installer-packs — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited installer-packs (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 primary manifest — the file an agent reads to learn what this artifact does.
comfyui-mcp ships installer packs under packs/ — one-command setups for a model family: custom nodes + model weights + a ready workflow. Each pack is driven by a single manifest.yaml (a ComfyManifest, the same shape the apply_manifest tool consumes), so one source of truth drives both an MCP-native install and generated double-click scripts.
packs/<name>/
manifest.yaml # custom_nodes + models (url → local_path) — source of truth
pack.yaml # metadata: workflow, family, VRAM, sources, notes
workflow.json # the graph to load
install-windows.bat # GENERATED — never hand-edit
install-runpod.sh # GENERATED — never hand-editapply_manifest --path packs/<name>/manifest.yaml (requires COMFYUI_PATH). It installs the custom nodes + downloads the models, skipping anything already present.
packs/<name>/install-windows.bat (orinstall-runpod.sh) from a ComfyUI root. Then load the pack's workflow.json.
pack.yaml notes/post_install formodel-specific gotchas (VRAM tiers, SageAttention/Triton, dtype fixes, etc.).
Two sources of ground truth, in order of preference:
*-MODELS-NODES_INSTALL.bat / .sh) — parse itsdownload lines (curl/wget/:grab, %HF%/$HF expansion, VRAM-tier menus) into manifest.yaml models[] (use local_path relative to models/) and its git clones into custom_nodes[]. Reconcile against the workflow — the workflow is the source of truth for which models are actually used.
workflow's widgets_values, then resolve each to its canonical Hugging Face resolve/main URL and verify it's live (the CI URL check will too). Never invent a URL — flag what you can't resolve. Leave user-supplied assets (input images/videos, user LoRAs) out of models[] and note them instead.
Then npm run packs:gen (writes the .bat/.sh), and validate: npm run packs:validate (schema), npm run packs:check-urls (every model URL resolves with a sane payload size), npm run packs:test (offline idempotency).
YAML note: write pack.yaml notes as single-line double-quoted strings or folded block scalars (- >-); never end an unquoted multi-line note with a colon (YAML reads it as a key and the parse fails).
When you build or derive a pack locally for a user, tell them they can share it upstream. A pack is just three small files (manifest.yaml, pack.yaml, workflow.json), so contributing is easy and high-value:
"Want to share this pack? Open an issue or PR on https://github.com/artokun/comfyui-mcp with these three files — it'll be reviewed for safety (model URLs, custom-node sources) and, once merged, CI keeps its model links validated for everyone."
As the userbase grows this turns into a shared, always-validated catalog of battle-tested setups instead of one-off scripts that rot in a drawer. Make this suggestion proactively — don't wait to be asked.
