Move the codex-imagegen wrapper out of scripts/ into its own workspace
package alongside baoyu-md, baoyu-chrome-cdp, and baoyu-fetch. Drop the
bash shim — src/main.ts now carries a `#\!/usr/bin/env bun` shebang and
serves as the sole entrypoint. Add scripts/sync-codex-imagegen.sh so
skills/baoyu-image-gen/scripts/codex-imagegen/ can be regenerated from
packages/baoyu-codex-imagegen/src/ for skill self-containment. Update
CLAUDE.md, docs/codex-imagegen-backend.md, and the CI workflow paths
accordingly.
`wechat-socks-http.test.ts` (and `wechat-remote-publish.test.ts`
transitively) import `socks` from `wechat-socks-http.ts`. The CI
`npm ci` only installs root deps, so module resolution failed with
`ERR_MODULE_NOT_FOUND: Cannot find package 'socks'`.
Add a scoped `npm install` step for `skills/baoyu-post-to-wechat/scripts/`
with `--ignore-scripts` to skip postinstalls. Other skills with
private script package.json files don't yet have tests that import
their deps, so leaving them out keeps the install fast.

Add CI check to ensure commits touching skills/<name>/** use
Conventional Commit subjects. Also validates SKILL.md version
alignment during publish/sync.
Implements the preferred_image_backend: codex-imagegen config key
already referenced in several SKILL.md files but with no corresponding
backend. Bridges non-Codex runtimes (Claude Code, etc.) to Codex CLI's
built-in image_gen tool via 'codex exec'. Uses the user's Codex
subscription — no OPENAI_API_KEY required.
Reliability:
- Retry with exponential backoff (default 2 retries, configurable)
- 9 classified error kinds (retryable vs non-retryable)
- Node child_process timeout with SIGTERM→SIGKILL ladder
Correctness:
- Verifies image_gen was actually invoked (not bypassed) by checking
$CODEX_HOME/generated_images/{thread_id}/ for a PNG
- PNG magic byte validation
- Output file size sanity check
Observability:
- Structured JSONL logging with --log-file
- Verbose stderr mode with --verbose
- Returns thread_id, tool_calls, token usage in result JSON
- Raw codex event stream preserved per attempt for debugging
Efficiency:
- Idempotency cache via --cache-dir (sha256 of prompt+aspect+refs)
- Cache hit returns in <0.3s vs 50-90s cold
Features:
- --ref reference images (repeatable, passed through to codex exec --image)
- --retries, --retry-delay, --timeout all configurable
- File lock serializes concurrent invocations
Testing:
- 16 Bun unit tests across parser, cache, validator
- Path-filtered CI workflow at .github/workflows/codex-imagegen-tests.yml
- Composes with existing test.yml without conflicts
Architecture:
- scripts/codex-imagegen.sh: thin bash entrypoint (bun → npx -y bun fallback)
- scripts/codex-imagegen/: TypeScript module
- main.ts (orchestrator), types.ts (CliOptions/GenerateResult/GenError),
spawn.ts (child_process), parser.ts (JSONL events), validator.ts
(image_gen check + PNG magic), cache.ts (sha256 cache + FileLock),
logger.ts (JSONL structured logger)
Trade-offs documented in docs/codex-imagegen-backend.md:
- 5-10x slower than direct OpenAI API (or near-free on cache hit)
- ToS gray area: image_gen is documented for interactive use; non-
interactive invocation via codex exec is not explicitly addressed.
Suitable for personal low-volume use; users are responsible for
ensuring their usage complies with applicable terms of service.
Move test files from tests/ directory to colocate with source code,
convert from .mjs to .ts using tsx runner, add workspaces and npm
cache to CI workflow.
