Stop Codex from satisfying a request by copying an unrelated pre-existing
image from generated_images instead of generating a new one. Verification
now requires a PNG in this thread's generated_images dir (or an image_gen
stream item, kept as a forward-compatible signal), and the spawned-agent
instruction forbids reading or reusing history images before image_gen is
called. Removes the findCpToTarget fallback that allowed the shortcut.
Validated against a real codex exec run: image_gen leaves no stream item,
so the filesystem check is the load-bearing signal; locked in via a
condensed real-stream regression fixture.
Closes#185
Expose Codex CLI's built-in image_gen tool through baoyu-image-gen's
standard CLI + batch flow as a dedicated provider. The provider spawns
the bundled scripts/codex-imagegen/main.ts (synced from
packages/baoyu-codex-imagegen/src/) so the skill remains self-contained
and inherits retry, cache, file-lock, and JSONL logging. No
OPENAI_API_KEY required — uses the user's Codex subscription.
New env vars: BAOYU_CODEX_IMAGEGEN_{BIN,CACHE_DIR,TIMEOUT_MS,RETRIES,LOG_FILE}.
Hyphenated provider names now resolve under-scored env vars (e.g.,
BAOYU_IMAGE_GEN_CODEX_CLI_CONCURRENCY). codex-cli is never auto-selected
— pin via --provider or default_provider in EXTEND.md.
