comfyui-pack-live-smoke

comfyui-pack-live-smoke is a skill for Claude Code from laurigates/claude-plugins. It costs 48 tokens per session (2,291 once invoked), scanned B, original, MIT.

A live testing tool for checking a ComfyUI custom-node pack in an actually running ComfyUI instance, through a browser or its API.

In plain words
What is it for?
It helps verify a pack end to end before opening a registry or GitOps pull request, including frontend behavior, backend routes, and feature permissions.
Why use it?
It catches interface and browser-to-server problems that isolated unit tests can miss, such as a disabled button or an incorrect request format.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade B, and why

comfyui-pack-live-smoke scanned grade B with 2 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

How it starts

The opening of the file, as written. The whole thing — 167 lines — stays where its author put it; the contents beside it link to each section on GitHub.

comfyui-pack-live-smoke

A ComfyUI pack's just check (pytest + vitest + tsc + build) can be fully green while the pack is broken in the running app, because the two halves are tested in isolation: pytest stubs server/folder_paths, vitest only covers DOM-free pure helpers, and the modal DOM + the frontend↔backend contract (route names, JSON shapes, gating predicates) are exercised by neither. Stand the pack up in a real ComfyUI and click through it (or drive it headlessly over the API) before opening the registry/gitops PR. This is where bugs that ship green actually surface.

Canonical break (comfyui-touch-manager, 2026-06): every gate green, jsdom modal mount green — yet live in the running app the Install-from-URL button was disabled on the normal 127.0.0.1 setup. The frontend gated on config.allow_remote_install alone (the non-loopback env override) while the backend /install gate actually permits the clone when is_loopback || override. The headline feature was dead in the common case; only a browser smoke caught it.

When to Use This Skill

Use this skill when... Use instead when...
Verifying a pack end-to-end in a running ComfyUI instance before opening a PR Writing the pack's code in the first place -> comfyui-node-authoring
Confirming an edited/built workflow JSON actually runs Editing the workflow JSON itself -> comfy-workflow-json

Target host — COMFYUI_HOST

Every recipe below reads the target instance from the COMFYUI_HOST environment variable, defaulting to 127.0.0.1:8188 (a local/CPU-fork smoke). Set it in .claude/settings.local.json's env block (gitignored, per-machine) to point at a different install without hardcoding a host in any command:

{ "env": { "COMFYUI_HOST": "192.0.2.10:8188" } }

Lesson 1: frontend gating must mirror the backend gate's full predicate

When the backend enforces a security/permission gate, the frontend's show/enable/disable logic must replicate the entire predicate, not a convenient sub-flag. Gating on a partial predicate silently disables a feature in the case the backend would have allowed.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
