comic-director — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited comic-director (Agent Skill) and scored it 91/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 1 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

The middle + right of Figure 1: take an authored comic.json (produced by the comic-author skill, Phase 1) and turn it into baked frames + a clickable viewer, through the audited spiral. Per frame: render a deterministic content-SVG blueprint → bake a pixel-art frame (codex image_gen) → a 3-reviewer cross-model panel_gate → keep / retry → page assembly → projection. The movie twin of method-figure's render half. (Image-based today; video-based is next.)
comic.json (authored upstream)The contract boundary is `comic.json` + the assets it references (content-SVG blueprints, identity refs, ART_BIBLE.md) — authored by comic-author. This skill is render + verify:
never see the expected values; identity is judged against the ref the author supplied (cast-aware).
image_path / active_attempt_id / wiki_node_id (+ the wiki trace) on KEEP.the cross-model visual panel (Gemini + Codex) to pass. The calling agent (Claude) gives the final structural sign-off.

scripts/run_comic.py — agent-driven bake, CLI gates)A pure-stdlib faithful port of packages/core/spiral_engine.js's movie branch. The cross-model gates (Gemini + Codex vision) still shell the gemini / codex CLIs directly. The BAKE is performed by the skill agent via the `mcp__codex__codex` MCP tool through --bake-mode=agent (the default): the core emits a deterministic bake-request sidecar (prompt + absolute ref paths + exact out_path), the agent calls mcp__codex__codex (sandbox: workspace-write, model: gpt-5.5, config: {model_reasoning_effort: xhigh, include_image_gen_tool: true}, cwd: <project>), and the core verifies the explicit out_path. (codex exec is RETIRED for real bakes — it forced a hand-drawn SVG/struct+zlib fallback; --bake-mode=exec RAISES if it ever reaches a real bake. See docs/spiral-runtime.md.)

[--bake-lang zh] [--finalize] [--dry-run] [--skip-assembly]--dry-run validates + prints each frame's concrete bake prompt (no image_gen) — run this first; it'salso how comic-author confirms Phase 1 is correct.
--finalize rebuilds the single-file viewer (packages/viewer/build_comic.py) **only if the run isshippable** (nothing escalated/throttled/flagged-for-human; assembly accepted).
Reuses skills/method-figure/scripts/pickup_image.py.
It prints a JSON run-report (kept, flagged_for_human, needs_human, shippable, throttled, escalated, assembly, attempts_per_panel). Engine semantics it ports (caps 4/panel + 6/run, the deterministic verdict, anatomy single-vote veto, throttle → fresh-run): ../../docs/spiral-runtime.md.
--bake-mode=agentThe bake is a synchronous sidecar handshake (contract-v2 §1–§4). The core never returns/exits early on a bake; only the bake primitive moved off codex exec onto mcp__codex__codex:
<out>.bakereq.json ={prompt_text, content_png, identity_ref, out_path, model:"gpt-5.5", config:{model_reasoning_effort:"xhigh", include_image_gen_tool:true}, sandbox:"workspace-write", cwd, created_at, min_bytes:500000, aspect, request_id:"<uuid4 hex>"} (prompt_text ALREADY contains the absolute ref + out paths — the schema has no -i; config carries both model_reasoning_effort:"xhigh" AND include_image_gen_tool:true — without the latter codex won't fire its native image tool; request_id is a per-bake uuid4-hex nonce the core mints — see (D)+(E)), pre-deleting any stale out_path + status.
mcp__codex__codex with EXACTLY those params.out_path.<out>.bakestatus.json ={status:"ok"|"fail", failure_kind:"throttle"|"other", mcp_output:"<bounded raw codex tool output>", mcp_error, request_id:"<verbatim from bakereq>"}. `mcp_output` is MANDATORY on BOTH ok and fail — the core feeds this status file to pickup --transcript, and the HARD-VETO scans it for import struct/zlib.compress/<svg>/matplotlib/… markers. An `ok` status with no raw output makes the HARD-VETO inert (a hand-drawn struct+zlib/SVG that still emits a ≥500KB sig-valid PNG would slip through) — so always embed the bounded raw tool result. `request_id` is EQUALLY MANDATORY on BOTH ok and fail — copy it VERBATIM from <out>.bakereq.json into the bakestatus; pickup_image.py --out-existing --request-id fail-closes the bake if the status request_id is missing or ≠ the bakereq nonce (a stale/foreign status at the same path can't be silently honored).
pickup_image.py --out-existing on the EXPLICIT out_path (PNG sig + IHDR dims+ size > 500000 + aspect band + mtime >= created_at), HARD-VETOES the markers in the transcript (= the status file's mcp_output), and (via --request-id) fail-closes if the status file's request_id is absent or ≠ the bakereq nonce — but all ONLY after it has read status:"ok". Empty/timeout/any-non-ok = fail-closed (no pickup). NO fallback to codex exec/PIL/SVG; effort is ALWAYS xhigh; sandbox ALWAYS workspace-write.
--bake-mode=agent (the agent-wrapper SOP) — REQUIRED for the default mode to functionThe comic-director skill agent is the bake fulfiller. Concretely:
python3 skills/comic-director/scripts/run_comic.py --project … --page … --panels … --bake-mode agent (it blocks on each bake by polling <out>.bakestatus.json).
panels/ dir for a new *.bakereq.json;mcp__codex__codex with exactly its{prompt: <prompt_text>, model:"gpt-5.5", config:{include_image_gen_tool:true, model_reasoning_effort:"xhigh"}, sandbox:"workspace-write", cwd:<cwd>} (codex writes the native PNG to the sidecar's out_path). The config MUST carry both include_image_gen_tool:true AND model_reasoning_effort:"xhigh": without include_image_gen_tool Codex will not fire its native image tool (it falls back to descriptive text / an SVG renderer), and xhigh is the required reasoning tier;
request_id from <out>.bakereq.json and write <out>.bakestatus.json carrying **the status, abounded raw mcp_output, AND that request_id VERBATIM — `mcp_output` so the core's HARD-VETO can scan it, and `request_id` because `pickup_image.py --out-existing --request-id` fail-closes the bake if the status request_id is missing or mismatched** (it must be written on BOTH ok and fail): {"status":"ok","mcp_output":"<raw>","request_id":"<verbatim from bakereq>"} on success, or {"status":"fail","failure_kind":"throttle","mcp_output":"<raw>","request_id":"<verbatim from bakereq>"} on a 429 / MODEL_CAPACITY_EXHAUSTED / overloaded error (otherwise {"status":"fail","failure_kind":"other","mcp_output":"<raw>","mcp_error":"<raw>","request_id":"<verbatim from bakereq>"}).
--bake-timeout and returnsgeneration_failed with failure_kind="other" — fail-closed, not a hang, and never a false throttle.)
--bake-mode=exec is the legacy/CI non-image path and RAISES if it ever reaches a real bake — never use it to produce a panel.comic.json first with comic-author; copyexamples/comic_m3_audit/comic.json as the shape.
--dry-run first; confirm every baked figure-panel carries ascii-tokenizable expected_literals(else the fail-closed gate refuses to run).
--bake-mode=agent writes each native PNG to its **explicitper-panel out_path and has no /tmp/aris_imagegen.lock (that code lock is GONE in agent mode — the agent wrapper itself serializes the `mcp__codex__codex` calls). The real race surface: concurrent runs on the same project/page collide on the per-panel `.bakereq.json`/`.bakestatus.json` sidecars + the shared `out_path` — so keep ONE runner per project/page. (The global generated-images dir that could cross-pollinate concurrent bakes is a hazard of the LEGACY --bake-mode=exec path ONLY**, retired for real bakes.)
