-name: check
-description: |
-  Code quality auditor for the Trellis channel runtime. Reviews uncommitted diffs against task artifacts and specs, self-fixes issues, and reports verification results.
-provider: claude
-labels: [trellis, check]
---
-
-# Check Agent (channel runtime)
-
-You are the Check Agent spawned by `trellis channel spawn --agent check` inside the Trellis channel runtime. You receive an `Active task: <path>` line in your inbox; use it to locate task artifacts on disk.
-
-## Context
-
-Before reviewing, read in this order:
-
-1. `<task-path>/check.jsonl` if present — spec manifest curated for this turn; read every listed file
-2. `<task-path>/prd.md` — requirements
-3. `<task-path>/design.md` if present — technical design
-4. `<task-path>/implement.md` if present — execution plan
-5. `.trellis/spec/` — project-wide guidelines (load only what is relevant to the diff under review)
-
-## Core Responsibilities
-
-1. **Get the diff** — `git diff` / `git diff --staged` for uncommitted changes
-2. **Review against task artifacts** — does the diff satisfy `prd.md` (and `design.md` / `implement.md` if present)?
-3. **Review against specs** — naming, structure, type safety, error handling, conventions in `.trellis/spec/`
-4. **Self-fix** — when an issue is mechanical and small, fix it directly with the editing tools you have
-5. **Run verification** — project lint and typecheck on the changed scope
-6. **Report** — concrete findings with `file:line` citations and what was fixed vs. what is open
-
-## Forbidden Operations
-
- `git commit`
- `git push`
- `git merge`
-
-The supervising main session owns commits. Report the post-fix state; do not commit on its behalf.
-
-## Workflow
-
-1. Run `git diff --name-only` and `git diff` to scope the changes
-2. Read the task artifacts and relevant spec files
-3. For each issue:
-   - If mechanical (lint nit, missing type, wrong import, dead branch) → fix in-place
-   - If a design/judgment issue → record and report, do not silently rewrite
-4. Run the project's lint and typecheck on the changed scope after self-fixes
-5. Report
-
-## Report Format
-
-```
-## Self-Check Complete
-
-### Files Checked
- <path>
-
-### Issues Found and Fixed
-1. `<file>:<line>` — <what was wrong> → <what you changed>

-
-1. Read relevant specs based on task type and the files in `implement.jsonl` if present
-2. Read the task's `prd.md`, `design.md` if present, and `implement.md` if present
-3. Implement features following specs and existing patterns
-4. Run the project's lint and typecheck commands on the changed scope
-5. Report files touched, key decisions, and verification results back to the channel
-
-## Code Standards
-
- Follow existing code patterns
- Don't add unnecessary abstractions
- Only do what the PRD asks for; no speculative scope expansion
- Surface uncertainty back to the channel rather than guessing

-# Trellis Configuration
-# Project-level settings for the Trellis workflow system
-#
-# All values have sensible defaults. Only override what you need.
-
-#-------------------------------------------------------------------------------
-# Session Recording
-#-------------------------------------------------------------------------------
-
-# Commit message used when auto-committing journal/index changes
-# after running add_session.py
-session_commit_message: "chore: record journal"
-
-# Maximum lines per journal file before rotating to a new one
-max_journal_lines: 2000
-
-#-------------------------------------------------------------------------------
-# Session Auto-Commit
-#-------------------------------------------------------------------------------
-
-# Auto-commit behavior for session journal + task archive operations.
-# - true (default): scripts auto-stage and auto-commit journal / task changes
-#   after add_session.py / task.py archive runs.
-# - false: scripts do not touch git. Files (journal-*.md, task archive moves)
-#   are still written to disk; you decide whether to git add / commit.
-#
-# Use `false` if your project's .gitignore intentionally excludes `.trellis/`
-# and you want session data kept local-only, or if you prefer to review
-# staged changes manually before each commit.
-#
-# Accepts: true / false / yes / no / 1 / 0 / on / off (case-insensitive).
-#
-# session_auto_commit: true

-# Task Lifecycle Hooks
-#-------------------------------------------------------------------------------
-
-# Shell commands to run after task lifecycle events.
-# Each hook receives TASK_JSON_PATH environment variable pointing to task.json.
-# Hook failures print a warning but do not block the main operation.

-# hooks:

-# Monorepo / Packages
-#-------------------------------------------------------------------------------

-# Declare packages for monorepo projects.
-# Trellis auto-detects workspaces during `trellis init`, but you can also
-# configure them manually here.
-#
-# packages:
-#   frontend:

-#   backend:
-#     path: packages/backend
-#   docs:
-#     path: docs-site
-#     type: submodule
-#   # For polyrepo / meta-repo layouts (independent .git in each subdir),
-#   # mark the package with `git: true`. The runtime treats it as an
-#   # independent repository for things like git-context display.

-# Default package used when --package is not specified.
-# default_package: frontend
-
-#-------------------------------------------------------------------------------
-# Channel worker OOM guard
-#-------------------------------------------------------------------------------
-# Default safeguards for `trellis channel spawn` workers. The guard runs
-# at spawn time (cleans expired idle workers, then enforces the live-worker
-# budget) and inside each supervisor (self-terminates a worker that stays
-# continuously idle past `idle_timeout`).
-#
-# Precedence: CLI flag > env var (TRELLIS_CHANNEL_WORKER_IDLE_TIMEOUT /
-# TRELLIS_CHANNEL_MAX_LIVE_WORKERS) > this config > built-in default.
-#
-# `idle_timeout: 0` disables idle cleanup (workers can sit idle forever
-# unless explicitly killed or given `--timeout`).
-# `max_live_workers: 0` disables the spawn-time budget check.
-#

-  worker_guard:
-    idle_timeout: 5m

-
-#-------------------------------------------------------------------------------
-# Codex (dispatch behavior)
-#-------------------------------------------------------------------------------
-# Codex-only knob; other platforms ignore it. Default ("inline") makes the
-# main Codex agent edit code directly because Codex sub-agents run with
-# `fork_turns="none"` isolation and can't inherit the parent session's
-# task context. Set to "sub-agent" to opt into the legacy dispatch model
-# (main agent spawns trellis-implement / trellis-check / trellis-research
-# sub-agents).

-Safe git-add helpers for Trellis-owned paths.
-
-Why this module exists
----------------------
-A real user incident: a project's `.gitignore` listed `.trellis/` (company-wide
-template / personal habit). When `add_session.py` and `task.py archive` ran
-their auto-commit and `git add` failed with `ignored by .gitignore`, the AI
-agent driving the workflow "fixed" it by retrying with
-`git add -f .trellis/` — which fan-out-included every ignored subtree
-(`.trellis/.backup-*/`, `.trellis/worktrees/`, `.trellis/.template-hashes.json`,
-`.trellis/.runtime/`), committing 548 files / 83474 lines of caches/backups.
-
-Design
------
- Scripts only stage SPECIFIC product paths (journal files, index.md, the
-  current task dir, the archive dir). Never the whole `.trellis/` tree.
- If plain `git add <specific>` fails with "ignored by", DO NOT retry with
-  ``-f``. The presence of `.trellis/` in `.gitignore` is treated as user
-  intent ("keep .trellis/ local-only"). The script warns and skips the
-  auto-commit; users who want auto-staging can either fix their `.gitignore`
-  or set ``session_auto_commit: false`` and manage git themselves.
- The warning includes a negative example: ``Do NOT use `git add -f .trellis/` ...``
-  so any AI rereading the log doesn't reinvent the bug.
-
-History note: 0.5.10 introduced an automatic ``git add -f`` retry on the
-specific paths. That was reverted in 0.5.11 — auto-forcing into a tree the
-user had gitignored violates user intent even when the path list is narrow.
-The wider-grain forbidden command stays forbidden, and the narrow-grain auto
-``-f`` is gone too.

-# Code Reuse Thinking Guide
-
-> **Purpose**: Stop and think before creating new code - does it already exist?
-
---
-
-## The Problem
-
-**Duplicated code is the #1 source of inconsistency bugs.**
-
-When you copy-paste or rewrite existing logic:
- Bug fixes don't propagate
- Behavior diverges over time
- Codebase becomes harder to understand
-
---
-
-## Before Writing New Code
-
-### Step 1: Search First
-
-```bash
-# Search for similar function names
-grep -r "functionName" .
-
-# Search for similar logic
-grep -r "keyword" .
-```
-
-### Step 2: Ask These Questions
-
-| Question | If Yes... |
-|----------|-----------|
-| Does a similar function exist? | Use or extend it |
-| Is this pattern used elsewhere? | Follow the existing pattern |
-| Could this be a shared utility? | Create it in the right place |
-| Am I copying code from another file? | **STOP** - extract to shared |
-
---
-
-## Common Duplication Patterns
-
-### Pattern 1: Copy-Paste Functions
-
-**Bad**: Copying a validation function to another file
-
-**Good**: Extract to shared utilities, import where needed
-
-### Pattern 2: Similar Components
-
-**Bad**: Creating a new component that's 80% similar to existing
-
-**Good**: Extend existing component with props/variants
-
-### Pattern 3: Repeated Constants
-
-**Bad**: Defining the same constant in multiple files
-
-**Good**: Single source of truth, import everywhere
-
-### Pattern 4: Repeated Payload Field Extraction
-
-**Bad**: Multiple consumers cast the same JSON/event fields locally:
-
-```typescript
-const description = (ev as { description?: string }).description;
-const context = (ev as { context?: ContextEntry[] }).context;
-```
-
-This is duplicated contract logic even when the code is only two lines. Each
-consumer now has its own definition of what a valid payload means.
-
-**Good**: Put the decoder, type guard, or projection next to the data owner:
-
-```typescript
-if (isThreadEvent(ev)) {
-  renderThreadEvent(ev);
-}
-```
-
-**Rule**: If the same untyped payload field is read in 2+ places, create a
-shared type guard / normalizer / projection before adding a third reader.
-
---
-
-## When to Abstract
-
-**Abstract when**:
- Same code appears 3+ times
- Logic is complex enough to have bugs
- Multiple people might need this
-
-**Don't abstract when**:
- Only used once
- Trivial one-liner
- Abstraction would be more complex than duplication
-
---
-
-## After Batch Modifications
-
-When you've made similar changes to multiple files:
-
-1. **Review**: Did you catch all instances?
-2. **Search**: Run grep to find any missed
-3. **Consider**: Should this be abstracted?
-
-### Reducers Should Use Exhaustive Structure
-
-When state is derived from action-like values (`action`, `kind`, `status`,
-`phase`), prefer a reducer with one `switch` over scattered `if/else` updates.
-
-```typescript
-// BAD - action-specific state transitions are hard to audit
-if (action === "opened") { ... }
-else if (action === "comment") { ... }
-else if (action === "status") { ... }
-
-// GOOD - one reducer owns the transition table
-switch (event.action) {
-  case "opened":
-    ...
-    return;
-  case "comment":
-    ...
-    return;
-}
-```
-
-This matters when the event log is the source of truth. A reducer is the
-documented replay model; display code and commands should not duplicate pieces
-of that replay model.
-
---
-
-## Checklist Before Commit
-
- [ ] Searched for existing similar code
- [ ] No copy-pasted logic that should be shared
- [ ] No repeated untyped payload field extraction outside a shared decoder
- [ ] Constants defined in one place
- [ ] Similar patterns follow same structure
- [ ] Reducer/action transitions live in one reducer or command dispatcher
-

-
-## Gotcha: Python if/elif/else Exhaustive Check
-
-**Problem**: Python's if/elif/else chains have no compile-time exhaustive check. When you add a new value to a `Literal` type (e.g., `Platform`), existing if/elif/else chains silently fall through to `else` with wrong defaults.
-
-**Symptom**: New platform works partially — some methods return Claude defaults instead of platform-specific values. No error is raised.
-
-**Example** (`cli_adapter.py`):
-```python
-# BAD: "gemini" falls through to else, returns "claude"
-@property
-def cli_name(self) -> str:
-    if self.platform == "opencode":
-        return "opencode"
-    else:
-        return "claude"  # gemini silently gets "claude"!
-
-# GOOD: explicit branch for every platform
-@property
-def cli_name(self) -> str:
-    if self.platform == "opencode":
-        return "opencode"
-    elif self.platform == "gemini":
-        return "gemini"
-    else:
-        return "claude"
-```
-
-**Prevention**: When adding a new value to a Python `Literal` type, search for ALL if/elif/else chains that switch on that type and add explicit branches. Don't rely on `else` being correct for new values.
-
---
-
-## Gotcha: Asymmetric Mechanisms Producing Same Output
-
-**Problem**: When two different mechanisms must produce the same file set (e.g., recursive directory copy for init vs. manual `files.set()` for update), structural changes (renaming, moving, adding subdirectories) only propagate through the automatic mechanism. The manual one silently drifts.
-
-**Symptom**: Init works perfectly, but update creates files at wrong paths or misses files entirely.
-
-**Prevention**:
- **Best**: Eliminate the asymmetry — have the manual path call the automatic one (e.g., `collectTemplateFiles()` calls `getAllScripts()` instead of maintaining its own list)
- **If asymmetry is unavoidable**: Add a regression test that compares outputs from both mechanisms
- When migrating directory structures, search for ALL code paths that reference the old structure
-
-**Real example**: `trellis update` had a manual `files.set()` list for 11 scripts that `getAllScripts()` already tracked. Fix: replaced the manual list with a `for..of getAllScripts()` loop. See `update.ts` refactor in v0.4.0-beta.3.
-
---
-
-## Template File Registration (Trellis-specific)
-
-When adding new files to `src/templates/trellis/scripts/`:
-
-**Single registration point**: `src/templates/trellis/index.ts`
-
-1. Add `export const xxxScript = readTemplate("scripts/path/file.py");`
-2. Add to `getAllScripts()` Map
-
-That's it. `commands/update.ts` uses `getAllScripts()` directly — no manual sync needed.
-
-**Why this matters**: Without registration in `getAllScripts()`, `trellis update` won't sync the file to user projects. Bug fixes and features won't propagate.
-
-**History**: Before v0.4.0-beta.3, `update.ts` had its own hand-maintained file list that frequently fell out of sync with `getAllScripts()`. This caused 11 Python files to be silently skipped during `trellis update`. The fix was to eliminate the duplicate list and use `getAllScripts()` as the single source of truth.
-
-### Quick Checklist for New Scripts
-
-```bash
-# After adding a new .py file, verify it's in getAllScripts():
-grep -l "newFileName" src/templates/trellis/index.ts  # Should match
-```
-
-### Template Sync Convention
-
-`.trellis/scripts/` (dogfooded) and `packages/cli/src/templates/trellis/scripts/` (template) must stay identical. After editing `.trellis/scripts/`, always sync:
-
-```bash
-rsync -av --delete --exclude='__pycache__' .trellis/scripts/ packages/cli/src/templates/trellis/scripts/
-```
-
-**Gotcha**: Running rsync with wrong source/destination paths can create nested garbage directories (e.g., `.trellis/scripts/packages/cli/...`). Always double-check paths before running.

-# Cross-Layer Thinking Guide
-
-> **Purpose**: Think through data flow across layers before implementing.
-
---
-
-## The Problem
-
-**Most bugs happen at layer boundaries**, not within layers.
-
-Common cross-layer bugs:
-
- API returns format A, frontend expects format B
- Database stores X, service transforms to Y, but loses data
- Multiple layers implement the same logic differently
-
---
-
-## Before Implementing Cross-Layer Features
-
-### Step 1: Map the Data Flow
-
-Draw out how data moves:
-
-```
-Source → Transform → Store → Retrieve → Transform → Display
-```
-
-For each arrow, ask:
-
- What format is the data in?
- What could go wrong?
- Who is responsible for validation?
-
-### Step 2: Identify Boundaries
-
-| Boundary              | Common Issues                     |
-| --------------------- | --------------------------------- |
-| API ↔ Service         | Type mismatches, missing fields   |
-| Service ↔ Database    | Format conversions, null handling |
-| Backend ↔ Frontend    | Serialization, date formats       |
-| Component ↔ Component | Props shape changes               |
-
-### Step 3: Define Contracts
-
-For each boundary:
-
- What is the exact input format?
- What is the exact output format?
- What errors can occur?
-
---
-
-## Common Cross-Layer Mistakes
-
-### Mistake 1: Implicit Format Assumptions
-
-**Bad**: Assuming date format without checking
-
-**Good**: Explicit format conversion at boundaries
-
-### Mistake 2: Scattered Validation
-
-**Bad**: Validating the same thing in multiple layers
-
-**Good**: Validate once at the entry point
-
-### Mistake 3: Leaky Abstractions
-
-**Bad**: Component knows about database schema
-
-**Good**: Each layer only knows its neighbors
-
-### Mistake 4: Every Consumer Parses The Same Payload
-
-**Bad**: A command reads JSONL events and casts fields inline:
-
-```typescript
-const thread = (ev as { thread?: string }).thread;
-const labels = (ev as { labels?: string[] }).labels;
-```
-
-This looks local, but it means every consumer owns a private version of the
-event contract. The next field change will update one command and miss another.
-
-**Good**: Decode once at the event boundary, then export typed projections:
-
-```typescript
-if (!isThreadEvent(ev)) return false;
-return ev.thread === filter.thread;
-```
-
-**Rule**: For append-only logs, JSON streams, RPC payloads, or config files,
-create one owner for:
-
- event / payload type definitions
- type guards and normalization from `unknown`
- metadata projections used by UI commands
- reducers that replay state from the source of truth
-
-Rendering code may format fields, but it must not redefine the payload contract.
-
---
-
-## Checklist for Cross-Layer Features
-
-Before implementation:
-
- [ ] Mapped the complete data flow
- [ ] Identified all layer boundaries
- [ ] Defined format at each boundary
- [ ] Decided where validation happens
-
-After implementation:
-
- [ ] Tested with edge cases (null, empty, invalid)
- [ ] Verified error handling at each boundary
- [ ] Checked data survives round-trip
- [ ] Checked that consumers import shared decoders / projections instead of
-      casting payload fields locally
- [ ] Checked that derived state points back to the source event identifier
-      (`seq`, `id`, `version`) instead of inventing a second cursor
-
---
-
-## Cross-Platform Template Consistency
-
-In Trellis, command templates (e.g., `record-session.md`) exist in **multiple platforms** with identical or near-identical content. This is a cross-layer boundary.
-
-### Checklist: After Modifying Any Command Template
-
- [ ] Find all platforms with the same command: `find src/templates/*/commands/trellis/ -name "<command>.*"`
- [ ] Update all platform copies (Markdown `.md` and TOML `.toml`)
- [ ] For Gemini TOML: adapt line continuations (`\\` vs `\`) and triple-quoted strings
- [ ] Run `/trellis:check-cross-layer` to verify nothing was missed
-
-**Real-world example**: Updated `record-session.md` in Claude to use `--mode record`, but forgot iFlow, Kilo, OpenCode, and Gemini — caught by cross-layer check.
-
---
-
-## Generated Runtime Template Upgrade Consistency
-
-Some generated files are both documentation and runtime input. In Trellis,
-`.trellis/workflow.md` is parsed by `get_context.py`, `workflow_phase.py`,
-SessionStart filters, and per-turn hooks. Template changes must be validated
-against both fresh init and upgrade paths.
-
-### Checklist: After Modifying A Runtime-Parsed Template
-
- [ ] Identify every runtime parser that reads the template, not just the file
-      writer that installs it
- [ ] Check whether relevant syntax lives outside obvious managed regions
-      such as tag blocks
- [ ] Verify fresh `init` output and a versioned `update` scenario that writes
-      the older `.trellis/.version`
- [ ] Add an upgrade regression using an older pristine template fixture, then
-      assert the installed file reaches the current packaged shape
- [ ] Update the backend spec that owns the runtime contract
-
---
-
-## Versioned Documentation Boundary
-
-Versioned documentation is a cross-layer boundary: source paths, `docs.json`
-version routing, and the rendered version selector must all describe the same
-release line.
-
-### Checklist: Before Editing Versioned Docs
-
- [ ] Identify the target release line: stable, beta, or RC
- [ ] Verify the edited MDX path matches that line:
-  - stable: `docs-site/{start,advanced,...}` and `docs-site/zh/{start,advanced,...}`
-  - beta: `docs-site/beta/**` and `docs-site/zh/beta/**`
-  - RC: `docs-site/rc/**` and `docs-site/zh/rc/**`
- [ ] Verify `docs.json` navigation points the version label to the same paths
- [ ] Grep the opposite tree for release-line-specific terms before committing
- [ ] Treat beta content appearing under root release paths as a source-path bug,
-      not a rendering bug
-
-**Real-world example**: A beta-only task workflow change documented
-`prd.md` + `design.md` + `implement.md`, task-creation consent, and Codex
-mode banners under root `start/` and `advanced/` paths. The docs site then
-served 0.6 beta behavior under the Release selector. The fix was to restore root
-release docs, move the 0.6 content to `beta/` and `zh/beta/`, and add a grep
-audit for beta markers against the root release tree.
-
-**Real-world example**: Codex inline mode changed workflow platform markers from
-`[Codex]` / `[Kilo, Antigravity, Windsurf]` to `[codex-sub-agent]` /
-`[codex-inline, Kilo, Antigravity, Windsurf]`. Fresh init was correct, but
-`trellis update` only merged `[workflow-state:*]` blocks and preserved stale
-markers outside those blocks. Result: upgraded projects got new hook scripts
-but old workflow routing, so `get_context.py --mode phase --platform codex`
-could return empty Phase 2.1 detail.
-
---
-
-## Mode-Detection Probe Checklist
-
-When a CLI auto-detects a mode by probing a remote resource (e.g., checking if `index.json` exists to decide marketplace vs direct download):
-
-### Before implementing:
-
- [ ] Probe runs in **ALL** code paths that use the result (interactive, `-y`, `--flag` combos)
- [ ] 404 vs transient error are distinguished — don't treat both as "not found"
- [ ] Transient errors **abort or retry**, never silently switch modes
- [ ] Shared state (caches, prefetched data) is **reset** when context changes (e.g., user switches source)
- [ ] **Shortcut paths** (e.g., `--template` skipping picker) must have the same error-handling quality as the probed path — check that downstream functions don't call catch-all wrappers
-
-### After implementing:
-
- [ ] Trace every path from probe result to the mode-decision branch — no fallthrough
- [ ] External format contracts (giget URI, raw URLs) are tested or at least documented as comments
- [ ] Metadata reads consume a complete response or use a streaming parser — never parse a fixed-size prefix as full JSON
- [ ] When reconstructing a composite identifier from parsed parts, verify **all** fields are included and in the **correct position** (e.g., `provider:repo/path#ref` not `provider:repo#ref/path`)
- [ ] Verify that **action functions** called after a shortcut don't internally use the old catch-all fetch — they must use the probe-quality variant when error distinction matters
-
-**Real-world example**: Custom registry flow had 8 bugs across 3 review rounds: (1) probe only ran in interactive mode, (2) transient errors fell through to wrong mode, (3) giget URI had `#ref` in wrong position, (4) prefetched templates leaked across source switches, (5) `--template` shortcut bypassed probe but `downloadTemplateById` internally used catch-all `fetchTemplateIndex`, turning timeouts into "Template not found".
-
-**Real-world example**: Agent-session update hints fetched npm `latest` metadata with `response.read(4096)` and then parsed it as complete JSON. The `@mindfoldhq/trellis` package metadata exceeded 4 KB, so the JSON was truncated, parse failed silently, and the first session injection showed no update hint. Fix: read the complete response before parsing, and add a regression where `version` is followed by an 8 KB metadata tail.

-## When to Create Flow Documentation
-
-Create detailed flow docs when:
-
- Feature spans 3+ layers
- Multiple teams are involved
- Data format is complex
- Feature has caused bugs before

-
-## Event Log / Projection Boundary
-
-Append-only logs are cross-layer contracts. A single event travels through:
-
-```
-CLI input → event writer → events.jsonl → reader → filter → reducer → display
-```
-
-### Checklist: After Adding A New Event Kind Or Field
-
- [ ] Add the event kind to the central event taxonomy
- [ ] Add a typed event variant or type guard at the event layer
- [ ] Add normalization helpers for array/object fields that come from
-      user input or JSON
- [ ] Keep `seq` / `id` assignment in the event writer only
- [ ] Make filters and reducers consume the typed event guard, not local casts
- [ ] Make display code consume reducer output or typed events, not raw JSON
- [ ] Add at least one regression that proves history replay and live filtering
-      use the same filter model
-
-**Real-world example**: Thread channels added `kind: "thread"`, `description`,
-`context`, labels, and `lastSeq`. The first implementation replayed thread
-state correctly, but several commands still re-parsed event payload fields with
-local casts. The fix was to make the core event layer own `ThreadChannelEvent`
-and `isThreadEvent`, make `reduceChannelMetadata` the only channel metadata
-projection, and make `reduceThreads` the only thread replay reducer.

-## Quick Reference: Thinking Triggers
-
-### When to Think About Cross-Layer Issues
-
- [ ] Feature touches 3+ layers (API, Service, Component, Database)
- [ ] Data format changes between layers
- [ ] Multiple consumers need the same data
- [ ] You're not sure where to put some logic
- [ ] You are adding an event kind, JSONL record, RPC payload, or config field
- [ ] UI / command code starts casting raw payload fields directly
-
-→ Read [Cross-Layer Thinking Guide](./cross-layer-thinking-guide.md)
-
-### When to Think About Code Reuse
-
- [ ] You're writing similar code to something that exists
- [ ] You see the same pattern repeated 3+ times
- [ ] You're adding a new field to multiple places
- [ ] **You're modifying any constant or config**
- [ ] **You're creating a new utility/helper function** ← Search first!
- [ ] Two files read the same untyped payload field with local casts
- [ ] Multiple branches update the same derived state from `kind` / `action`
-
-→ Read [Code Reuse Thinking Guide](./code-reuse-thinking-guide.md)
-
-### When Verifying AI Cross-Review Results
-
- [ ] Reviewer claims "user input can be malicious" → Check the actual data source (internal manifest? user config? external API?)
- [ ] Reviewer flags "missing validation" → Is the data from a trusted internal source?
- [ ] Reviewer says "behavior change" → Read the code comments — is it intentional design?
- [ ] Reviewer identifies a "bug" in test → Mentally delete the feature being tested — does the test still pass? If yes → tautological test
-
-**Common AI reviewer false-positive patterns**:
-1. **Trust boundary confusion**: Treating internal data (bundled JSON manifests) as untrusted external input
-2. **Ignoring design comments**: Flagging intentional behavior documented in code comments as bugs
-3. **Variable misreading**: Not tracing a variable to its actual definition (e.g., Map keyed by path vs name)
-
-**Verification rule**: Every CRITICAL/WARNING finding must be verified against the actual code before prioritizing. Budget ~35% false-positive rate for AI reviews.
-
---
-
-## Pre-Modification Rule (CRITICAL)
-
-> **Before changing ANY value, ALWAYS search first!**
-
-```bash
-# Search for the value you're about to change
-grep -r "value_to_change" .
-```
-
-This single habit prevents most "forgot to update X" bugs.
-

-
-## How to Use This Directory
-
-1. **Before coding**: Skim the relevant thinking guide
-2. **During coding**: If something feels repetitive or complex, check the guides
-3. **After bugs**: Add new insights to the relevant guide (learn from mistakes)

-# Bootstrap Task: Fill Project Development Guidelines
-
-**You (the AI) are running this task. The developer does not read this file.**
-
-The developer just ran `trellis init` on this project for the first time.
-`.trellis/` now exists with empty spec scaffolding, and this bootstrap task
-exists under `.trellis/tasks/`. When they want to work on it, they should start
-this task from a session that provides Trellis session identity.
-
-**Your job**: help them populate `.trellis/spec/` with the team's real
-coding conventions. Every future AI session — this project's
-`trellis-implement` and `trellis-check` sub-agents — auto-loads spec files
-listed in per-task jsonl manifests. Empty spec = sub-agents write generic
-code. Real spec = sub-agents match the team's actual patterns.
-
-Don't dump instructions. Open with a short greeting, figure out if the repo
-has any existing convention docs (CLAUDE.md, .cursorrules, etc.), and drive
-the rest conversationally.
-
---
-
-## Status (update the checkboxes as you complete each item)
-
- [ ] Fill guidelines for vendor/ComfyUI_frontend
- [ ] Add code examples
-
---
-
-## Spec files to populate
-
-### Package: vendor/ComfyUI_frontend (`spec/vendor/ComfyUI_frontend/`)
-
- Frontend guidelines: `.trellis/spec/vendor/ComfyUI_frontend/frontend/`
-
-
-### Thinking guides (already populated)
-
-`.trellis/spec/guides/` contains general thinking guides pre-filled with
-best practices. Customize only if something clearly doesn't fit this project.
-
---
-
-## How to fill the spec
-
-### Step 1: Import from existing convention files first (preferred)
-
-Search the repo for existing convention docs. If any exist, read them and
-extract the relevant rules into the matching `.trellis/spec/` files —
-usually much faster than documenting from scratch.
-
-| File / Directory | Tool |
-|------|------|
-| `CLAUDE.md` / `CLAUDE.local.md` | Claude Code |
-| `AGENTS.md` | Codex / Claude Code / agent-compatible tools |
-| `.cursorrules` | Cursor |
-| `.cursor/rules/*.mdc` | Cursor (rules directory) |
-| `.windsurfrules` | Windsurf |
-| `.clinerules` | Cline |
-| `.roomodes` | Roo Code |
-| `.github/copilot-instructions.md` | GitHub Copilot |
-| `.vscode/settings.json` → `github.copilot.chat.codeGeneration.instructions` | VS Code Copilot |
-| `CONVENTIONS.md` / `.aider.conf.yml` | aider |
-| `CONTRIBUTING.md` | General project conventions |
-| `.editorconfig` | Editor formatting rules |
-
-### Step 2: Analyze the codebase for anything not covered by existing docs
-
-Scan real code to discover patterns. Before writing each spec file:
- Find 2-3 real examples of each pattern in the codebase.
- Reference real file paths (not hypothetical ones).
- Document anti-patterns the team clearly avoids.
-
-### Step 3: Document reality, not ideals
-
-**Critical**: write what the code *actually does*, not what it should do.
-Sub-agents match the spec, so aspirational patterns that don't exist in the
-codebase will cause sub-agents to write code that looks out of place.
-
-If the team has known tech debt, document the current state — improvement
-is a separate conversation, not a bootstrap concern.
-
---
-
-## Quick explainer of the runtime (share when they ask "why do we need spec at all")
-
- Every AI coding task spawns two sub-agents: `trellis-implement` (writes
-  code) and `trellis-check` (verifies quality).
- Each task has `implement.jsonl` / `check.jsonl` manifests listing which
-  spec files to load.
- The platform hook auto-injects those spec files + the task's `prd.md`
-  into every sub-agent prompt, so the sub-agent codes/reviews per team
-  conventions without anyone pasting them manually.
- Source of truth: `.trellis/spec/`. That's why filling it well now pays
-  off forever.
-
---
-
-## Completion
-
-When the developer confirms the checklist items above are done with real
-examples (not placeholders), guide them to run:
-
-```bash
-python3 ./.trellis/scripts/task.py finish
-python3 ./.trellis/scripts/task.py archive 00-bootstrap-guidelines
-```
-
-After archive, every new developer who joins this project will get a
-`00-join-<slug>` onboarding task instead of this bootstrap task.
-
---
-
-## Suggested opening line
-
-"Welcome to Trellis! Your init just set me up to help you fill the project
-spec — a one-time setup so every future AI session follows the team's
-conventions instead of writing generic code. Before we start, do you have
-any existing convention docs (CLAUDE.md, .cursorrules, CONTRIBUTING.md,
-etc.) I can pull from, or should I scan the codebase from scratch?"

-# Development Workflow
-
---
-
-## Core Principles
-
-1. **Plan before code** — figure out what to do before you start
-2. **Specs injected, not remembered** — guidelines are injected via hook/skill, not recalled from memory
-3. **Persist everything** — research, decisions, and lessons all go to files; conversations get compacted, files don't
-4. **Incremental development** — one task at a time
-5. **Capture learnings** — after each task, review and write new knowledge back to spec
-
---
-
-## Trellis System
-
-### Developer Identity
-
-On first use, initialize your identity:
-
-```bash
-python3 ./.trellis/scripts/init_developer.py <your-name>
-```
-
-Creates `.trellis/.developer` (gitignored) + `.trellis/workspace/<your-name>/`.
-
-### Spec System
-
-`.trellis/spec/` holds coding guidelines organized by package and layer.
-
- `.trellis/spec/<package>/<layer>/index.md` — entry point with **Pre-Development Checklist** + **Quality Check**. Actual guidelines live in the `.md` files it points to.
- `.trellis/spec/guides/index.md` — cross-package thinking guides.
-
-```bash
-python3 ./.trellis/scripts/get_context.py --mode packages   # list packages / layers
-```
-
-**When to update spec**: new pattern/convention found · bug-fix prevention to codify · new technical decision.
-
-### Task System
-
-Every task has its own directory under `.trellis/tasks/{MM-DD-name}/` holding `task.json`, `prd.md`, optional `design.md`, optional `implement.md`, optional `research/`, and context manifests (`implement.jsonl`, `check.jsonl`) for sub-agent-capable platforms.
-
-```bash
-# Task lifecycle
-python3 ./.trellis/scripts/task.py create "<title>" [--slug <name>] [--parent <dir>]
-python3 ./.trellis/scripts/task.py start <name>          # set active task (session-scoped when available)
-python3 ./.trellis/scripts/task.py current --source      # show active task and source
-python3 ./.trellis/scripts/task.py finish                # clear active task (triggers after_finish hooks)
-python3 ./.trellis/scripts/task.py archive <name>        # move to archive/{year-month}/
-python3 ./.trellis/scripts/task.py list [--mine] [--status <s>]
-python3 ./.trellis/scripts/task.py list-archive
-
-# Code-spec context (injected into implement/check agents via JSONL).
-# `implement.jsonl` / `check.jsonl` are seeded on `task create` for sub-agent-capable
-# platforms; the AI curates real spec + research entries during planning when needed.
-python3 ./.trellis/scripts/task.py add-context <name> <action> <file> <reason>
-python3 ./.trellis/scripts/task.py list-context <name> [action]
-python3 ./.trellis/scripts/task.py validate <name>
-
-# Task metadata
-python3 ./.trellis/scripts/task.py set-branch <name> <branch>
-python3 ./.trellis/scripts/task.py set-base-branch <name> <branch>    # PR target
-python3 ./.trellis/scripts/task.py set-scope <name> <scope>
-
-# Hierarchy (parent/child)
-python3 ./.trellis/scripts/task.py add-subtask <parent> <child>
-python3 ./.trellis/scripts/task.py remove-subtask <parent> <child>
-
-# PR creation
-python3 ./.trellis/scripts/task.py create-pr [name] [--dry-run]
-```
-
-> Run `python3 ./.trellis/scripts/task.py --help` to see the authoritative, up-to-date list.
-
-**Current-task mechanism**: `task.py create` creates the task directory and (when session identity is available) auto-sets the per-session active-task pointer so the planning breadcrumb fires immediately. `task.py start` writes the same pointer (idempotent if already set) and flips `task.json.status` from `planning` to `in_progress`. State is stored under `.trellis/.runtime/sessions/`. If no context key is available from hook input, `TRELLIS_CONTEXT_ID`, or a platform-native session environment variable, there is no active task and `task.py start` fails with a session identity hint. `task.py finish` deletes the current session file (status unchanged). `task.py archive <task>` writes `status=completed`, moves the directory to `archive/`, and deletes any runtime session files that still point at the archived task.
-
-### Workspace System
-
-Records every AI session for cross-session tracking under `.trellis/workspace/<developer>/`.
-
- `journal-N.md` — session log. **Max 2000 lines per file**; a new `journal-(N+1).md` is auto-created when exceeded.
- `index.md` — personal index (total sessions, last active).
-
-```bash
-python3 ./.trellis/scripts/add_session.py --title "Title" --commit "hash" --summary "Summary"
-```
-
-### Context Script
-
-```bash
-python3 ./.trellis/scripts/get_context.py                            # full session runtime
-python3 ./.trellis/scripts/get_context.py --mode packages            # available packages + spec layers
-python3 ./.trellis/scripts/get_context.py --mode phase --step <X.Y>  # detailed guide for a workflow step
-```

-<!--
-  WORKFLOW-STATE BREADCRUMB CONTRACT (read this before editing the tag blocks below)
-
-  The [workflow-state:STATUS] blocks embedded in the ## Phase Index section
-  below are the SINGLE source of truth for the per-turn `<workflow-state>`
-  breadcrumb that every supported AI platform's UserPromptSubmit hook
-  reads. inject-workflow-state.py (Python platforms) and
-  inject-workflow-state.js (OpenCode plugin) only parse them — there is no
-  fallback dict baked into the scripts after v0.5.0-rc.0.
-
-  STATUS charset: [A-Za-z0-9_-]+. When the hook can't find a tag, it
-  degrades to a generic "Refer to workflow.md for current step." line —
-  intentionally visible so users notice and fix a broken workflow.md.
-
-  INVARIANT (test/regression.test.ts):
-    Every workflow-walkthrough step marked `[required · once]` must have a
-    matching enforcement line in its phase's [workflow-state:*] block. The
-    breadcrumb is the only per-turn channel; if a mandatory step isn't
-    mentioned there, the AI silently skips it (Phase 1 planning gate
-    skip and Phase 3.4 commit skip both manifested via this gap).
-
-  TAG ↔ PHASE scoping:
-    [workflow-state:no_task]      → no active task; before Phase 1
-    [workflow-state:planning]     → all of Phase 1 (status='planning')
-    [workflow-state:planning-inline] → Codex inline variant of Phase 1
-    [workflow-state:in_progress]  → Phase 2 + Phase 3.2-3.4
-                                    (status stays 'in_progress' from
-                                    task.py start until task.py archive)
-    [workflow-state:in_progress-inline] → Codex inline variant of Phase 2/3
-    [workflow-state:completed]    → currently DEAD: cmd_archive flips
-                                    status and moves the dir in the same
-                                    call, so the resolver loses the
-                                    pointer (block kept for a future
-                                    explicit in_progress→completed
-                                    transition)
-
-  Editing checklist:
-    - When you change a [workflow-state:STATUS] block, also check the
-      matching phase's `[required · once]` walkthrough steps for sync
-    - Run `trellis update` after editing to push the new bodies to

-## Phase Index
-
-```
-Phase 1: Plan    → classify, get task-creation consent, then write planning artifacts
-Phase 2: Execute → implement only after task status is in_progress
-Phase 3: Finish  → verify, update spec, commit, and wrap up
-```
-
-### Request Triage
-
- Simple conversation or small task: ask only whether this turn should create a Trellis task. If the user says no, skip Trellis for this session.
- Complex task: ask whether you may create a Trellis task and enter planning. If the user says no, do not do broad inline implementation; explain, clarify scope, or suggest a smaller split.
- User approval to create a task is not approval to start implementation. Planning still happens first.
-
-### Planning Artifacts
-
- `prd.md` — requirements, constraints, and acceptance criteria. Do not put technical design or execution checklists here.
- `design.md` — technical design for complex tasks: boundaries, contracts, data flow, tradeoffs, compatibility, rollout / rollback shape.
- `implement.md` — execution plan for complex tasks: ordered checklist, validation commands, review gates, and rollback points.
- `implement.jsonl` / `check.jsonl` — spec and research manifests for sub-agent context. They do not replace `implement.md`.
- Lightweight tasks may be PRD-only. Complex tasks must have `prd.md`, `design.md`, and `implement.md` before `task.py start`.
-
-### Parent / Child Task Trees
-
-Use a parent task when one user request contains several independently verifiable deliverables. The parent task owns the source requirement set, the task map, cross-child acceptance criteria, and final integration review; it normally should not be the implementation target unless it also has direct work.
-
-Use child tasks for deliverables that can be planned, implemented, checked, and archived independently. Parent/child structure is not a dependency system: if one child must wait for another, write that ordering in the child `prd.md` / `implement.md` and keep each child's acceptance criteria testable.
-
-Create new children with `task.py create "<title>" --slug <name> --parent <parent-dir>`. Link existing tasks with `task.py add-subtask <parent> <child>`, and unlink mistakes with `task.py remove-subtask <parent> <child>`.
-
-<!-- Per-turn breadcrumb: shown when there is no active task (before Phase 1) -->
-
-[workflow-state:no_task]
-No active task. First classify the current turn and ask for task-creation consent before creating any Trellis task.
-Simple conversation / small task: ask only whether this turn should create a Trellis task. If the user says no, skip Trellis for this session.
-Complex task: ask the user if you can create a Trellis task and enter the planning phase. If the user says no, explain, clarify scope, or suggest a smaller split.

- 1.0 Create task `[required · once]` (only after task-creation consent)
- 1.1 Requirement exploration `[required · repeatable]` (`prd.md`; complex tasks also need `design.md` + `implement.md`)
- 1.2 Research `[optional · repeatable]`
- 1.3 Configure context `[required · once]` — Claude Code, Cursor, OpenCode, Codex, Kiro, Gemini, Qoder, CodeBuddy, Copilot, Droid, Pi (sub-agent-dispatch platforms only; inline platforms skip)
- 1.4 Activate task `[required · once]` (review gate, then `task.py start`; status → in_progress)
- 1.5 Completion criteria

-Multi-deliverable scope: consider a parent task plus independently verifiable child tasks; dependencies must be written in child artifacts, not implied by tree position.
-Sub-agent mode: curate `implement.jsonl` and `check.jsonl` as spec/research manifests before start.

- 2.2 Quality check `[required · repeatable]`
- 2.3 Rollback `[on demand]`

-     Scope: all of Phase 2 + Phase 3.2-3.4 (status stays 'in_progress' from
-     task.py start until task.py archive; only archive flips it). The body
-     therefore must cover every required step from implementation through
-     commit, including Phase 3.3 spec update and Phase 3.4 commit. -->
-
-Sub-agent dispatch protocol applies to all platforms and all sub-agents, including class-2 Codex/Copilot/Gemini/Qoder and `trellis-research`: every dispatch prompt starts with `Active task: <task path from task.py current>` before role-specific instructions.
-
-[workflow-state:in_progress]
-Tools: `trellis-implement` / `trellis-research` are sub-agent types only (Task/Agent tool, NOT Skill; there is no skill by these names). `trellis-update-spec` is a skill. `trellis-check` exists as both; prefer the Agent form when verifying after code changes.
-Flow: `trellis-implement` -> `trellis-check` -> `trellis-update-spec` -> commit (Phase 3.4) -> `/trellis:finish-work`.
-Main-session default: dispatch implement/check sub-agents. Sub-agent self-exemption: if already running as `trellis-implement`, do NOT spawn another `trellis-implement` or `trellis-check`; if already running as `trellis-check`, do NOT spawn another `trellis-check` or `trellis-implement`. Dispatch is main session only.
-Dispatch prompt starts with `Active task: <task path from task.py current>`. Read context: jsonl entries -> `prd.md` -> `design.md if present` -> `implement.md if present`.

-
-[workflow-state:completed]
-Code committed. Run `/trellis:finish-work`; if dirty, return to Phase 3.4 first.
-[/workflow-state:completed]
-
-### Rules
-
-1. Identify which Phase you're in, then continue from the next step there
-2. Run steps in order inside each Phase; `[required]` steps can't be skipped
-3. Phases can roll back (e.g., Execute reveals a prd defect → return to Plan to fix, then re-enter Execute)
-4. Steps tagged `[once]` are skipped if the output already exists; don't re-run
-5. Artifact presence informs the next step; missing `design.md` / `implement.md` is valid for lightweight tasks and incomplete planning for complex tasks.
-
-### Active Task Routing
-
-When a user request matches one of these intents inside an active task, route first, then load the detailed phase step if needed.

-
- Planning or unclear requirements -> `trellis-brainstorm`.
- `in_progress` implementation/check -> dispatch `trellis-implement` / `trellis-check`.
- Repeated debugging -> `trellis-break-loop`; spec updates -> `trellis-update-spec`.

- Repeated debugging -> `trellis-break-loop`; spec updates -> `trellis-update-spec`.
-
-[/codex-inline, Kilo, Antigravity, Devin]
-
-### Guardrails
-
- Task creation approval is not implementation approval; implementation waits for `task.py start` after artifact review.
- PRD-only is valid for lightweight tasks; complex tasks need `design.md` + `implement.md`.
- Planning must be persisted to task artifacts; checks must run before reporting completion.
-
-### Loading Step Detail
-
-At each step, run this to fetch detailed guidance:
-
-```bash
-python3 ./.trellis/scripts/get_context.py --mode phase --step <step>
-# e.g. python3 ./.trellis/scripts/get_context.py --mode phase --step 1.1
-```
-
---
-
-## Phase 1: Plan
-
-Goal: classify the request, get task-creation consent when a task is needed, and produce the planning artifacts required before implementation.
-
-#### 1.0 Create task `[required · once]`
-
-Create the task directory only after task-creation consent. The command sets status to `planning`, writes `task.json`, creates a default `prd.md`, and auto-targets the new task when session identity is available:
-
-```bash
-python3 ./.trellis/scripts/task.py create "<task title>" --slug <name>
-```
-
-`--slug` is the human-readable name only. Do **not** include the `MM-DD-` date prefix; `task.py create` adds that prefix automatically.
-
-For task trees, create the parent task first and then create each child with `--parent <parent-dir>`. Do not start the parent just because children exist; start the child that owns the next independently verifiable deliverable.
-
-After this command succeeds, the per-turn breadcrumb auto-switches to `[workflow-state:planning]`, telling the AI to stay in planning.
-
-Run only `create` here — do not also run `start`. `start` flips status to `in_progress`, which switches the breadcrumb to the implementation phase before planning artifacts are reviewed. Save `start` for step 1.4.
-
-Skip when `python3 ./.trellis/scripts/task.py current --source` already points to a task.
-
-#### 1.1 Requirement exploration `[required · repeatable]`
-
-Load the `trellis-brainstorm` skill and explore requirements interactively with the user per the skill's guidance.
-
-The brainstorm skill will guide you to:
- Ask one question at a time
- Prefer researching over asking the user
- Prefer offering options over open-ended questions
- Update `prd.md` immediately after each user answer
- Split large scopes into a parent task plus child tasks when the deliverables can be verified independently
- Keep `prd.md` focused on requirements and acceptance criteria
- For complex tasks, produce `design.md` and `implement.md` before implementation starts
-
-When considering a parent/child split:
- Use a parent task when one request contains several independently verifiable deliverables.
- Parent tasks own source requirements, child-task mapping, cross-child acceptance criteria, and final integration review.
- Child tasks own actual deliverables that can be planned, implemented, checked, and archived independently.
- Parent/child structure is not a dependency system. If child B depends on child A, write that ordering in child B's `prd.md` / `implement.md`.
- Start the child task that owns the next deliverable. Do not start the parent unless the parent itself has direct implementation work.
-
-Return to this step whenever requirements change and revise the relevant artifact.
-
-#### 1.2 Research `[optional · repeatable]`
-
-Research can happen at any time during requirement exploration. It isn't limited to local code — you can use any available tool (MCP servers, skills, web search, etc.) to look up external information, including third-party library docs, industry practices, API references, etc.
-
-[Claude Code, Cursor, OpenCode, codex-sub-agent, Kiro, Gemini, Qoder, CodeBuddy, Copilot, Droid, Pi]
-
-Spawn the research sub-agent:
-
- **Agent type**: `trellis-research`
- **Task description**: Research <specific question>
- **Key requirement**: Research output MUST be persisted to `{TASK_DIR}/research/`
-
-[/Claude Code, Cursor, OpenCode, codex-sub-agent, Kiro, Gemini, Qoder, CodeBuddy, Copilot, Droid, Pi]
-
-[codex-inline, Kilo, Antigravity, Devin]
-
-Do the research in the main session directly and write findings into `{TASK_DIR}/research/`. (For `codex-inline` this avoids the `fork_turns="none"` isolation that prevents `trellis-research` sub-agents from resolving the active task path.)
-
-[/codex-inline, Kilo, Antigravity, Devin]
-
-**Research artifact conventions**:
- One file per research topic (e.g. `research/auth-library-comparison.md`)
- Record third-party library usage examples, API references, version constraints in files
- Note relevant spec file paths you discovered for later reference
-
-Brainstorm and research can interleave freely — pause to research a technical question, then return to talk with the user.
-
-**Key principle**: Research output must be written to files, not left only in the chat. Conversations get compacted; files don't.
-
-#### 1.3 Configure context `[required · once]`
-
-[Claude Code, Cursor, OpenCode, codex-sub-agent, Kiro, Gemini, Qoder, CodeBuddy, Copilot, Droid, Pi]
-
-Curate `implement.jsonl` and `check.jsonl` so the Phase 2 sub-agents get the right spec/research context. These files were seeded on `task create` with a single self-describing `_example` line; your job here is to fill in real entries.
-
-**Location**: `{TASK_DIR}/implement.jsonl` and `{TASK_DIR}/check.jsonl` (already exist).
-
-**Format**: one JSON object per line — `{"file": "<path>", "reason": "<why>"}`. Paths are repo-root relative.
-
-**What to put in**:
- **Spec files** — `.trellis/spec/<package>/<layer>/index.md` and any specific guideline files (`error-handling.md`, `conventions.md`, etc.) relevant to this task
- **Research files** — `{TASK_DIR}/research/*.md` that the sub-agent will need to consult
-
-**What NOT to put in**:
- Code files (`src/**`, `packages/**/*.ts`, etc.) — those are read by the sub-agent during implementation, not pre-registered here
- Files you're about to modify — same reason
-
-**Split between the two files**:
- `implement.jsonl` → specs + research the implement sub-agent needs to write code correctly
- `check.jsonl` → specs for the check sub-agent (quality guidelines, check conventions, same research if needed)
-
-These manifests do not replace `implement.md`. `implement.md` is the human-readable execution plan for a complex task; jsonl files only list context files to inject or load.
-
-**How to discover relevant specs**:
-
-```bash
-python3 ./.trellis/scripts/get_context.py --mode packages
-```
-
-Lists every package + its spec layers with paths. Pick the entries that match this task's domain.
-
-**How to append entries**:
-
-Either edit the jsonl file directly in your editor, or use:
-
-```bash
-python3 ./.trellis/scripts/task.py add-context "$TASK_DIR" implement "<path>" "<reason>"
-python3 ./.trellis/scripts/task.py add-context "$TASK_DIR" check "<path>" "<reason>"
-```
-
-Delete the seed `_example` line once real entries exist (optional — it's skipped automatically by consumers).
-
-Skip when: `implement.jsonl` and `check.jsonl` have agent-curated entries (the seed row alone doesn't count).
-

-
-[codex-inline, Kilo, Antigravity, Devin]
-
-Skip this step. Context is loaded directly by the `trellis-before-dev` skill in Phase 2.
-
-[/codex-inline, Kilo, Antigravity, Devin]
-
-#### 1.4 Activate task `[required · once]`
-
-After artifact review, flip the task status to `in_progress`:
-
-```bash
-python3 ./.trellis/scripts/task.py start <task-dir>
-```
-
-For lightweight tasks, `prd.md` can be enough. For complex tasks, `prd.md`, `design.md`, and `implement.md` must exist and be reviewed before start. On sub-agent-capable platforms, curate jsonl manifests when extra spec or research context is needed; seed-only manifests are tolerated by consumers.
-
-After this command succeeds, the breadcrumb auto-switches to `[workflow-state:in_progress]`, and the rest of Phase 2 / 3 follows.
-
-If `task.py start` errors with a session-identity message (no context key from hook input, `TRELLIS_CONTEXT_ID`, or platform-native session env), follow the hint in the error to set up session identity, then retry.

-

-
-[/Claude Code, Cursor, OpenCode, codex-sub-agent, Kiro, Gemini, Qoder, CodeBuddy, Copilot, Droid, Pi]
-
-[codex-inline, Kilo, Antigravity, Devin]
-
-Load the `trellis-check` skill and verify the code per its guidance:
- Spec compliance
- lint / type-check / tests
- Cross-layer consistency (when changes span layers)
-
-If issues are found → fix → re-check, until green.
-
-[/codex-inline, Kilo, Antigravity, Devin]
-
-**Final pass (before Phase 3.4 commit)**: the last 2.2 of a task must run full-scope, not just on the latest implement chunk. List all affected packages with `python3 ./.trellis/scripts/get_context.py --mode packages`, then load each package's spec index Quality Check section. This catches cross-layer / multi-package issues a mid-iteration local 2.2 cannot.
-
-#### 2.3 Rollback `[on demand]`
-
- `check` reveals a prd defect → return to Phase 1, fix `prd.md`, then redo 2.1
- Implementation went wrong → revert code, redo 2.1
- Need more research → research (same as Phase 1.2), write findings into `research/`
-
---
-
-## Phase 3: Finish
-
-Goal: ensure code quality, capture lessons, record the work.
-
-#### 3.2 Debug retrospective `[on demand]`
-
-If this task involved repeated debugging (the same issue was fixed multiple times), load the `trellis-break-loop` skill to:
- Classify the root cause
- Explain why earlier fixes failed
- Propose prevention
-
-The goal is to capture debugging lessons so the same class of issue doesn't recur.
-
-#### 3.3 Spec update `[required · once]`
-
-Load the `trellis-update-spec` skill and review whether this task produced new knowledge worth recording:
- Newly discovered patterns or conventions
- Pitfalls you hit
- New technical decisions
-
-Update the docs under `.trellis/spec/` accordingly. Even if the conclusion is "nothing to update", walk through the judgment.
-
-#### 3.4 Commit changes `[required · once]`
-
-**Spec-sync preamble**: before drafting commits, ask: did this task fix a bug or surface non-obvious knowledge that should land in `.trellis/spec/` so future-you (or future-AI) doesn't repeat the mistake? If yes, return to Phase 3.3 first — spec writes belong in the same task's commit batch, not as a forgotten follow-up.
-
-The AI drives a batched commit of this task's code changes so `/finish-work` can run cleanly afterwards. Goal: produce work commits FIRST, then bookkeeping (archive + journal) commits land after — never interleaved.
-
-**Step-by-step**:
-
-1. **Inspect dirty state**:
-   ```bash
-   git status --porcelain
-   ```
-   Snapshot every dirty path. If the working tree is clean, skip to 3.5.
-
-2. **Learn commit style** from recent history (so drafted messages blend in):
-   ```bash
-   git log --oneline -5
-   ```
-   Note the prefix convention (`feat:` / `fix:` / `chore:` / `docs:` ...), language (中文/English), and length style.
-
-3. **Classify dirty files into two groups**:
-   - **AI-edited this session** — files you wrote/edited via Edit/Write/Bash tool calls in this session. You know what changed and why.
-   - **Unrecognized** — dirty files you did NOT touch this session (could be the user's manual edits, leftover WIP from a previous session, or unrelated work). Do NOT silently include these.
-
-4. **Draft a commit plan**. Group AI-edited files into logical commits (1 commit per coherent change unit, not 1 commit per file). Each entry: `<commit message>` + file list. List unrecognized files separately at the bottom.
-
-5. **Present the plan once, ask for one-shot confirmation**. Format:
-   ```
-   Proposed commits (in order):
-     1. <message>
-        - <file>
-        - <file>
-     2. <message>
-        - <file>
-
-   Unrecognized dirty files (NOT in any commit — confirm include/exclude):
-     - <file>
-     - <file>
-
-   Reply 'ok' / '行' to execute. Reply with edits, or '我自己来' / 'manual' to abort.
-   ```
-
-6. **On confirmation**: run `git add <files>` + `git commit -m "<msg>"` for each batch in order. Do not amend. Do not push.
-
-7. **On rejection** (user replies "不行" / "我自己来" / "manual" / any pushback on the plan): stop. Do not attempt a second plan. The user will commit by hand; you skip ahead to 3.5 once they confirm.
-
-**Rules**:
- No `git commit --amend` anywhere — three-stage three-commit flow (work commits → archive commit → journal commit).
- Never push to remote in this step.
- If the user wants different message wording but accepts the file grouping, edit the message and re-confirm once — but if they reject the grouping, exit to manual mode.
- The batched plan is one prompt; do not prompt per commit.
-
-#### 3.5 Wrap-up reminder
-
-After the above, remind the user they can run `/finish-work` to wrap up (archive the task, record the session).

-## Customizing Trellis (for forks)
-
-This section is for developers who want to modify the Trellis workflow itself. All customization is done by editing this file; the scripts are parsers only.
-
-### Changing what a step means
-
-Edit the corresponding step's walkthrough body in the Phase 1 / 2 / 3 sections above. Critical invariants:
- No active task must triage first and ask for task-creation consent before creating a Trellis task.
- Planning must distinguish lightweight PRD-only tasks from complex tasks that require `prd.md`, `design.md`, and `implement.md` before start.
- Every required execution path must keep the Phase 3.4 commit reminder reachable before `/trellis:finish-work`.
-
-All tag blocks live in the `## Phase Index` section above, immediately after each phase summary:
-
-| Scope | Corresponding tag |
-|---|---|
-| No active task (before Phase 1) | `[workflow-state:no_task]` (after the Phase Index ASCII art) |
-| All of Phase 1 (task created → ready for implementation) | `[workflow-state:planning]` (after Phase 1 summary) |
-| Codex inline Phase 1 | `[workflow-state:planning-inline]` |
-| Phase 2 + Phase 3.2–3.4 (implementation + check + wrap-up) | `[workflow-state:in_progress]` (after Phase 2 summary) |
-| Codex inline Phase 2 + Phase 3.2–3.4 | `[workflow-state:in_progress-inline]` |
-| After Phase 3.5 (archived) | `[workflow-state:completed]` (after Phase 3 summary; **currently DEAD**) |
-
-### Changing the per-turn prompt text
-
-Directly edit the body of the corresponding `[workflow-state:STATUS]` block. After editing, run `trellis update` (if you're a template maintainer) or restart your AI session (if you're customizing your own project) — no script changes required.
-
-### Adding a custom status
-
-Add a new block:
-
-```
-[workflow-state:my-status]
-your per-turn prompt text
-[/workflow-state:my-status]
-```
-
-Constraints:
- STATUS charset: `[A-Za-z0-9_-]+` (underscores and hyphens allowed, e.g. `in-review`, `blocked-by-team`)
- A lifecycle hook must write `task.json.status` to your custom value, otherwise the tag is never read
- Lifecycle hooks live in `task.json.hooks.after_*` and bind to one of `after_create / after_start / after_finish / after_archive`
-
-### Adding a lifecycle hook
-
-Add a `hooks` field to your `task.json`:
-
-```json
-{
-  "hooks": {
-    "after_finish": [
-      "your-script-or-command-here"
-    ]
-  }
-}
-```
-
-Supported events: `after_create / after_start / after_finish / after_archive`. Note that `after_finish` ≠ a status change (it only clears the active-task pointer); use `after_archive` for "task is done" notifications.
-

-## Getting Started
-
-### For New Developers
-
-Run the initialization script:
-
-```bash
-python3 ./.trellis/scripts/init_developer.py <your-name>
-```
-
-This will:
-1. Create your identity file (gitignored)
-2. Create your progress directory
-3. Create your personal index
-4. Create initial journal file
-
-### For Returning Developers
-
-1. Get your developer name:
-   ```bash
-   python3 ./.trellis/scripts/get_developer.py
-   ```
-
-2. Read your personal index:
-   ```bash
-   cat .trellis/workspace/$(python3 ./.trellis/scripts/get_developer.py)/index.md
-   ```
-
---
-
-## Guidelines
-
-### Journal File Rules
-
- **Max 2000 lines** per journal file
- When limit is reached, create `journal-{N+1}.md`
- Update your personal `index.md` when creating new files
-
-### Session Record Format
-
-Each session should include:
- Summary: One-line description
- Branch: Which branch the work was done on
- Main Changes: What was modified
- Git Commits: Commit hashes and messages
- Next Steps: What to do next
-
---
-
-## Session Template
-
-Use this template when recording sessions:
-
-```markdown
-## Session {N}: {Title}
-
-**Date**: YYYY-MM-DD
-**Task**: {task-name}
-**Branch**: `{branch-name}`
-

 - 【TTS】       → 自动调用 TTS API
 - 【WORKFLOW】  → 输出 ComfyUI 工作流 JSON

+## 即梦 Provider（图片 + 视频）
+
+火山引擎「智能视觉 / CV」异步生成 provider，图片与视频共用一套「提交 → 轮询 → 转存 → 计费」状态机，靠 `capability → req_key` 映射区分能力。
+
+- **能力映射**（`services/jimeng/types.rs` 单一事实源）：
+  - 图片 `JimengCapability::Image` → `req_key = jimeng_t2i_v40`，轮询 ~2s / 超时 ~120s，产物 `image_urls[]`（或 `binary_data_base64[]`），24h 有效
+  - 视频 `JimengCapability::Video` → `req_key = jimeng_ti2v_v30_pro`，轮询 ~8s / 超时 ~600s，产物 `video_url`，**仅 1h 有效**
+  - 新增能力（视频3.0 / OmniHuman 等）只加枚举分支，submit/poll/转存逻辑不动
+- **签名只当签名器**：用 `volc-visual-sdk` 的 `VisualClient::build_signed_request`（纯签名 V4），HTTP 走 metapi 自己的 async `state.http`，绝不调 SDK 的 blocking `request()`（依赖以 `default-features = false` 引入，不拉 `reqwest::blocking`）。Action 显式传 `CVSync2AsyncSubmitTask` / `CVSync2AsyncGetResult`（Version `2022-08-31`，走 query），业务参数走 JSON body。
+- **解析铁律**：先判外层 `code == 10000` 再读 `data.status`（错误响应 `data:null`，顺序反了会 panic）；错误码可重试性见 `types::classify`（输入审核类不可重试，QPS/输出审核类可重试，内部错误码视频可重试、图片不重试）。
+- **任务模型零迁移**：复用 `background_tasks`（`task_type = jimeng-image-generation` / `jimeng-video-generation`，本地 id `jmi_*` / `jmv_*`），火山 `task_id` 存进 `result_json.volcTaskId`，进度 1=已提交 / 2=生成中 / 3=转存中 / 4=完成。
+- **产物转存**：轮询到 `done` 立即 `workspace::record_remote_asset`（视频 1h 过期硬约束，绝不透传火山临时 URL），对外只发本地 `public_id` + `/api/user/workspace/assets/{id}/file`。
+- **计费**：复用 `UsageTracker` 的 `record_comfy_task_success/failure`（`model = req_key`，单价来自 `config.jimeng.{image_cost,video_cost}`，首版默认 0）。
+- **路由**（鉴权照 `picture_agent` 的 bearer / JWT 解析）：
+  - `POST /api/jimeng/image/jobs`、`POST /api/jimeng/video/jobs` → 立即返回本地 task_id，后台 `tokio::spawn` 轮询
+  - `GET /api/jimeng/jobs`、`GET /api/jimeng/jobs/{id}`、`POST /api/jimeng/jobs/{id}/cancel`、`GET /api/jimeng/status`
+- **配置**：`[jimeng]` 段，AK/SK 走 env（`BOOSAPI_JIMENG__ACCESS_KEY` / `__SECRET_KEY` / 可选 `__SESSION_TOKEN`），不硬编码；`enabled=false` 时路由返回 503「能力未启用」。
+- **首版范围**：图生视频只支持 `image_urls`（公网图 URL），前端上传 → 转存留二期；`frames ∈ {121(5s), 241(10s)}`，`aspect_ratio` 白名单。
+
+### 即梦在「站点管理 / 连接管理」里的特殊处理（platform=`jimeng`）
+
+即梦作为一个 `platform = "jimeng"` 录进现有 `sites` + `accounts` 体系（复用 CRUD / 列表 / 状态 UI），但因为它**不是 OpenAI 兼容协议**（火山 V4 HMAC 签名、异步两步生成、无 `/models` 端点），所有 OpenAI 专属路径都为它开了**干净的分支**，绝不污染其它平台：
+
+- **平台判定**：`routes::admin::accounts::is_jimeng_platform(&site.platform)`（大小写不敏感）是唯一事实源；站点 `platform` 字段为自由字符串，无白名单，前端下拉新增 `jimeng` 选项即可。
+- **AK/SK 存法**：AK 落 `accounts.access_token`；SK + region/host/session_token 收进 `extra_config.jimeng.{secretKey,region,host,sessionToken}` JSON。`credentialMode` 强制 `apikey`（只在「API Key 管理」分段出现，永不进 session 分段）。**SK / sessionToken 是机密**：列表 / get / update 响应一律用 `mask_account_extra_config` 替换为 `••••`；带掩码的 `extra_config` 回写会被 `update_account` 拒绝（留空即保留原值）。
+- **验证（签名探测）**：`verify_token` 检测到 jimeng 平台时走 `verify_jimeng_token` → `JimengProvider::from_credentials(ak, sk, region, host, session).verify()`，对 GetResult 发一个哨兵 `task_id` 的最小签名请求。火山网关在业务层之前校验 V4 签名：签名通过 → 业务层报「任务不存在」（即 `Authenticated`）；签名失败 → 网关返回鉴权类 `Code`（`classify_verify_response` 按 `is_auth_error_code` 判定 `AuthFailed`）。**绝不调 `/models`**，绝不触发生成。
+- **不进路由表**：`create_account` 检测 jimeng 后走 `create_jimeng_account`，单条插入、**不** `spawn_route_rebuild`；前端 `handleTokenAdd` 对 jimeng 也跳过 `checkModels` / `rebuildRoutes`。
+- **站点 probe 短路**：`build_probe_plan`（probe-now / probe-stream 共用入口）对 jimeng 直接 `BadRequest`，提示改用连接管理的「验证」做签名连通性检查（逐模型 chat 探测对它无意义）。
+- **运行健康来源**：jimeng 不走 OpenAI 代理通道（独立 `/api/jimeng/*`），`proxy_logs` 无记录，否则永远 `unknown`。改由 `derive_jimeng_runtime_health` 从最近一条 `background_tasks`（`jimeng-image/video-generation`）派生平台级健康（succeeded→healthy / failed→unhealthy / running·pending→进行中 / 无任务→「凭证验证通过后即可使用」），`account_response_value_with_jimeng` 在站点为 jimeng 时用它覆盖 proxy-log 派生值；其它平台传入的 jimeng 健康一律忽略（回归零影响，有断言测试守护）。
+- **前端表单**：`Sites.tsx` 选 jimeng 时预填 URL `https://visual.volcengineapi.com`，隐藏「API 请求地址池」与「刷新后自动探测」；`Accounts.tsx` 在 API Key 分段对 jimeng 改成 AK + SK（必填）+ region/host/session（选填），点「验证 AK/SK 签名」做签名探测，校验通过才能添加。

+### 内置 pgrust（Preview）
+
+BoosAPI 可选托管随发布目录携带的 pgrust，不监听 TCP，也不使用 Docker。启用后首次启动会在
+`data/pgrust` 原子初始化 PostgreSQL 18.3 数据目录，通过权限为 `0700` 的 Unix socket
+连接，自动创建 `boosapi` 数据库并执行 `migrations_pg`。BoosAPI 退出时会先向 pgrust
+发送 SIGINT，超时后才强制结束；Linux 上父进程异常退出也会触发 pgrust 关闭。
+
+```bash
+# 构建固定版本的 pgrust runtime（首次较慢，后续复用 target/pgrust-build）
+scripts/build_pgrust_runtime.sh
+
+# 可选：牺牲首次链接速度，进一步压缩二进制
+PGRUST_SIZE_OPTIMIZED=1 scripts/build_pgrust_runtime.sh
+
+# 验证 initdb、迁移、HTTP 健康检查和父子进程共同退出
+scripts/smoke_embedded_pgrust.sh
+```
+
+生产构建设置 `INCLUDE_PGRUST_RUNTIME=1 ./build-and-run.sh --production` 才会把
+`pgrust/bin/postgres`、PG 18.3 share
+资源、上游 commit 信息和 AGPL-3.0 许可证一起放入发布目录。内置构建关闭私有 Unix
+socket 不需要的 PAM/LDAP，并剥离符号；可选体积模式额外使用 thin LTO。Alpine 构建需要
+`icu-dev openssl-dev libxml2-dev`；运行机器需要对应动态库。
+若 BoosAPI 以 root 启动，pgrust 会降权到配置的 `run_uid/run_gid`（默认 65534）；发布
+目录必须允许该 UID 读取，数据目录必须允许其写入。推荐让 BoosAPI 本身直接以专用非 root
+用户运行。
+上游版本固定在 `scripts/build_pgrust_runtime.sh` 的 `PGRUST_REF`，升级时必须重新执行
+内置冒烟。当前上游仍声明尚未 production-ready；外部数据库可通过
+`BOOSAPI_DB__URL` 是默认且推荐的生产数据库路径。

+# Open Agent SDK (Rust)
+
+> Vendored from `codeany-ai/open-agent-sdk-rust` revision
+> `24fef177b033301cd6a61de7d344bfac9b8bb442`. The Desktop portability patches
+> present when the crate was consolidated are retained on top of that baseline.
+
+A lightweight, open-source Rust SDK for building AI agents. Run the full agent loop in-process — no CLI or subprocess required. Deploy anywhere: cloud, serverless, Docker, CI/CD.
+
+Also available in [TypeScript](https://github.com/codeany-ai/open-agent-sdk-typescript) and [Go](https://github.com/codeany-ai/open-agent-sdk-go).
+
+## Features
+
+- **Multi-Provider** — Supports both Anthropic Messages API and OpenAI Chat Completions API, with auto-detection by model name
+- **Agent Loop** — Streaming agentic loop with tool execution, multi-turn conversations, and cost tracking
+- **25+ Built-in Tools** — Bash, Read, Write, Edit, Glob, Grep, WebFetch, WebSearch, Agent (subagents), AskUser, Tasks, Teams, Plans, Worktrees, Todos, Cron, LSP, Config, MCP Resources, ToolSearch
+- **Session Persistence** — Save, load, fork, and resume conversations across sessions
+- **MCP Support** — Connect to MCP servers via stdio, HTTP, and SSE transports
+- **Permission System** — Configurable tool approval with allow/deny rules and filesystem path validation
+- **Hook System** — 20+ hook events: PreToolUse, PostToolUse, SessionStart/End, SubagentStart/Stop, TaskCreated/Completed, FileChanged, PreCompact/PostCompact, and more
+- **Extended Thinking** — Support for extended thinking with budget tokens
+- **Cost Tracking** — Per-model token usage and pricing for Anthropic, OpenAI, and DeepSeek models
+- **Custom Tools** — Implement the `Tool` trait to add your own tools
+- **Auto-Compaction** — Multi-tier context compression (micro-compact, LLM summarization, image stripping)
+- **Sandbox Config** — Network and filesystem restrictions for tool execution
+- **File State Cache** — LRU cache for file state tracking and staleness detection
+
+## Quick Start
+
+```toml
+[dependencies]
+open-agent-sdk = "0.1.0"
+tokio = { version = "1", features = ["full"] }
+```
+
+```rust
+use open_agent_sdk::{Agent, AgentOptions, SDKMessage};
+use open_agent_sdk::types;
+
+#[tokio::main]
+async fn main() {
+    let mut agent = Agent::new(AgentOptions::default()).await.unwrap();
+
+    // Streaming
+    let (mut rx, handle) = agent.query("What files are in this directory?").await;
+    while let Some(event) = rx.recv().await {
+        match event {
+            SDKMessage::Assistant { message, .. } => {
+                print!("{}", types::extract_text(&message));
+            }
+            SDKMessage::Result { text, cost_usd, .. } => {
+                println!("\nDone (${:.4})", cost_usd);
+            }
+            _ => {}
+        }
+    }
+    handle.await.unwrap();
+
+    // Or use the blocking API
+    let result = agent.prompt("Count lines in Cargo.toml").await.unwrap();
+    println!("{}", result.text);
+
+    agent.close().await;
+}
+```

+
+## Custom Tools
+
+Implement the `Tool` trait:
+
+```rust
+use async_trait::async_trait;
+use open_agent_sdk::*;
+use serde_json::{json, Value};
+use std::collections::HashMap;
+use std::sync::Arc;
+
+struct MyTool;
+
+#[async_trait]
+impl Tool for MyTool {
+    fn name(&self) -> &str { "MyTool" }
+    fn description(&self) -> &str { "Does something useful" }
+    fn input_schema(&self) -> ToolInputSchema {
+        ToolInputSchema {
+            schema_type: "object".to_string(),
+            properties: HashMap::from([(
+                "input".to_string(),
+                json!({"type": "string", "description": "The input"}),
+            )]),
+            required: vec!["input".to_string()],
+            additional_properties: Some(false),
+        }
+    }
+    fn is_read_only(&self, _: &Value) -> bool { true }
+    async fn call(&self, input: Value, _ctx: &ToolUseContext) -> Result<ToolResult, ToolError> {
+        Ok(ToolResult::text("result"))
+    }
+}
+
+// Use it
+let agent = Agent::new(AgentOptions {
+    custom_tools: vec![Arc::new(MyTool)],
+    ..Default::default()
+}).await.unwrap();
+```
+
+## Session Persistence
+
+```rust
+use open_agent_sdk::session::*;
+
+// Save current session
+save_session(&session_data).await.unwrap();
+
+// List all sessions
+let sessions = list_sessions().await.unwrap();
+
+// Resume a session
+let data = load_session("session-id").await.unwrap();
+
+// Fork a session
+let new_id = fork_session("session-id").await.unwrap();
+```
+
+## MCP Servers
+
+```rust
+use open_agent_sdk::types::McpServerConfig;
+
+let agent = Agent::new(AgentOptions {
+    mcp_servers: HashMap::from([(
+        "filesystem".to_string(),
+        McpServerConfig::Stdio {
+            command: "npx".to_string(),
+            args: vec!["-y".to_string(), "@modelcontextprotocol/server-filesystem".to_string(), "/tmp".to_string()],
+            env: HashMap::new(),
+        },
+    )]),
+    ..Default::default()
+}).await.unwrap();
+```
+

+
+## Multi-Provider Support
+
+The SDK automatically detects which API format to use based on the model name:
+
+| Models | API Format | Auto-detected |
+|--------|-----------|---------------|
+| Claude (sonnet, opus, haiku) | Anthropic Messages | Yes |
+| GPT-4o, O1, O3, O4 | OpenAI Chat Completions | Yes |
+| DeepSeek, Qwen, Mistral | OpenAI Chat Completions | Yes |
+| LLaMA, Gemma, Gemini, Yi, GLM | OpenAI Chat Completions | Yes |
+
+Override with `CODEANY_API_TYPE=openai-completions` or `CODEANY_API_TYPE=anthropic-messages`.
+
+Works with any OpenAI-compatible endpoint (OpenRouter, vLLM, Ollama, LiteLLM, etc.):
+
+```bash
+export CODEANY_BASE_URL=https://openrouter.ai/api
+export CODEANY_API_KEY=your-key
+export CODEANY_MODEL=anthropic/claude-sonnet-4
+cargo run --example 01-simple-query

boos	36a69c265f	feat(jimeng-ui): record Jimeng connections via sites/accounts (方案甲) Onboard Jimeng (火山视觉) as a `platform = "jimeng"` entry in the existing sites/accounts console, reusing the CRUD/list/status UI while branching every OpenAI-specific path so no other platform is affected. Jimeng is not OpenAI-compatible (Volcengine V4 HMAC signing, async two-step generation, no `/models` endpoint), so each branch keys off the single source of truth `routes::admin::accounts::is_jimeng_platform` (case-insensitive). Backend (src/routes/admin, src/services/jimeng): - create_account → create_jimeng_account: AK lands in accounts.access_token; SK + region/host/sessionToken nest under extra_config.jimeng.*; credentialMode forced to "apikey". No spawn_route_rebuild — Jimeng never enters the route table. - Secret protection: SK/sessionToken masked with •••• on list/get/update responses (mask_account_extra_config); update_account rejects a masked extra_config write-back so an edit round-trip can't clobber the real secret. - verify_token → verify_jimeng_token: signs a sentinel GetResult probe via JimengProvider::from_credentials(...).verify(). The Volcengine gateway checks the V4 signature before the business layer, so a valid AK/SK is Authenticated (business layer reports "not found") and a bad one yields an auth-class Code (classify_verify_response / is_auth_error_code). Never calls /models, never triggers generation. - build_probe_plan short-circuits Jimeng (probe-now/-stream) with a BadRequest pointing operators at the connection "验证" flow. - runtimeHealth: Jimeng has no proxy_logs, so derive_jimeng_runtime_health reads the latest jimeng background_tasks row; account_response_value_with_jimeng applies it only when the site is Jimeng and ignores the override otherwise. Frontend (src/web): - Sites.tsx: add jimeng platform option; prefill visual.volcengineapi.com; hide URL pool + auto-probe sections. - Accounts.tsx: AK + SK(required) + region/host/session fields under the API Key segment; "验证 AK/SK 签名" gates add; skip model sync / route rebuild. - api.ts: verify-token payload carries secretKey/region/host/sessionToken. Tests: unit coverage for credential nesting, secret masking, verify-response classification, and regression guards proving non-Jimeng accounts ignore the Jimeng health override and keep their proxy-log-derived health. Also: stop tracking the stray root package-lock.json (repo installs via pnpm) and gitignore it.	2026-06-23 16:09:49 +08:00

boos	f1265d863a	test(jimeng): cover poll state machine edges Exercise the decision logic and async driver beyond the happy path: - decide() consults the business code before data.status (fatal and retryable codes win over a bogus done status) - not_found is terminal - exponential backoff grows 1,2,4,8 and caps at 8x the interval - backoff multiplier resets after a normal generating wait - a retryable code followed by a fatal one stops the loop	2026-06-23 14:22:43 +08:00
boos	d956b3f9f4	test(jimeng): cover body assembly and poll parameters Round out request-body validation and pin the polling parameters: - all five allowed aspect ratios and both frame counts build - prompt + image_urls together both land in the video body - whitespace-only prompt is dropped but an image still satisfies one-of - optional video fields are omitted when absent - default poll interval/timeout values (image 2s/120s, video 8s/600s)	2026-06-23 14:22:43 +08:00
boos	bf16139695	test(jimeng): cover classify edges and response parsing Add unit tests for error-code classification boundaries and response decoding that the existing cases left open: - 50516/50517 are capability-independent (retryable for image too) - adjacent copyright codes 50518 (fatal) vs 50519 (retryable) - full 50520..=50522 service-exception range is fatal - 50500/50501 fatal-for-image / retryable-for-video via classify directly - negative codes are fatal (no poll loop) - base64 image output and absent (not just null) data field decode safely	2026-06-23 14:22:34 +08:00
boos	bd129fc160	fix(billing): new users get zero quota by default not unlimited A freshly registered user's auto-provisioned default downstream key must start with a zero spend allowance, not unlimited. Two parts: - DEFAULT_NEW_USER_MAX_COST_USD changes from 1.0 to 0.0, so new users have no free spend until they top up or an admin raises the cap. - The constant's docs now spell out the failure mode it guards: a NULL max_cost is treated as unlimited by the proxy, so the column must always be bound on INSERT. The registration path (routes::auth::register) and the admin create-user path (routes::admin::users) both already include the max_cost column and bind this constant, so both now persist 0.0 rather than leaving NULL. Tests (cargo test --lib routes::auth::tests, 10 passed): assert the constant is 0.0, and run the registration key INSERT against an in-memory DB to verify the stored max_cost is non-NULL and exactly 0.0. The agent suites (approval/sandbox/bash_sandbox/toctou) stay green.	2026-06-23 13:25:52 +08:00
boos	cb5c0febbd	fix(auth): drop duplicate pixelle_video field in test AppConfig The test AppConfig initializer in routes::auth listed pixelle_video twice (a merge artifact from stacking the Gemini and comfy-cloud branches), which made the lib test binary fail to compile with E0062 and blocked `cargo test --lib` for the whole crate. Remove the duplicate; lib tests build again.	2026-06-23 13:25:52 +08:00

boos	018d832972	chore: add volc-visual-sdk dependency (signer only, no blocking)	2026-06-23 11:57:52 +08:00
boos	b41bfd4d49	docs: note the embedded desktop subproject in the project layout Point the project-structure section at desktop/, clarify it is an independent Cargo workspace (excluded from the backend crate), and link to desktop/README.md for build steps.	2026-06-22 11:33:03 +08:00
boos	e0a5f57793	feat(desktop): embed BoosAPI Desktop client as a subproject Vendor the rebranded BoosAPI Desktop client (Tauri + Vue) into metapi as a monorepo subdirectory under desktop/. Source only — node_modules, dist, Cargo target and the upstream .git history are excluded. desktop/ keeps its own independent Cargo workspace (desktop/src-tauri with crates/*); it is not part of the backend boosapi crate, so a `cargo check` at the metapi root still compiles only the backend. Build the desktop app from desktop/src-tauri per desktop/README.md. Note: app icons are still placeholder assets pending the final BoosAPI logo. The updater signing keys live outside the repo and are not included.	2026-06-22 11:32:57 +08:00
boos	d9c78ecc73	chore: ignore embedded desktop build artifacts The desktop/ subproject (added next) carries its own node_modules, dist, and Cargo target dirs once built. Ignore them from the metapi root so the 6.5G+ of generated output never enters the repo.	2026-06-22 11:32:46 +08:00
