report-bug

report-bug is a skill for Claude Code, Codex from sandyup/comfyui-mcp. It costs 135 tokens per session (1,898 once invoked), scanned A, original, MIT.

A coding-agent procedure for diagnosing software bugs, trying a safe local fix, and sending the issue to the appropriate project. It covers ComfyUI, a tool for building image-generation workflows, its sidebar panel, custom nodes, and ComfyUI itself.

In plain words
What is it for?
Use it to trace errors to their root cause, apply a small local repair, and report bugs in ComfyUI-related projects through the correct channel.
Why use it?
It helps the agent continue working when a real software bug occurs instead of stopping at the error. It also separates software defects from ordinary workflow problems such as missing models or out-of-memory errors.

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 A, and why

report-bug scanned grade A with 1 finding 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 3d 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.

Self-heal & report bugs (make the ecosystem better)

Goal: when something is broken, don't just stop — diagnose it, try to fix it so the user keeps working, and get the fix/report to whoever can fix it upstream. Do this autonomously: act, then inform the user with a short summary — don't pepper them with permission prompts. (Exceptions where you DO pause: a fix that touches the user's own workflow/data, anything large/risky, or anything you can't make safe — explain and ask.)

This is for bugs in software, not ordinary workflow/generation errors (OOM, missing model, bad params → use troubleshooting). First decide whose bug it is.

Step 1 — Diagnose (root cause, not symptom)

  • Read the exact error + stack. For ComfyUI runs: get_history, get_logs.
  • Follow the stack to the actual file/line. Read the code there.
  • Form a concrete root cause + a minimal fix you can defend.

Step 2 — Classify whose bug it is

  • OURScomfyui-mcp (server/tools/orchestrator/agent) or comfyui-mcp-panel (the sidebar pack / panel JS / __init__.py). → Steps 3–5 (self-heal + Worker/PR).
  • THIRD-PARTY — a custom node pack, or ComfyUI core itself. → Step 6 (their GitHub; our Worker can't file there).

Step 3 — Attempt a local fix (so the user keeps working)

Patch the code where it actually runs so relief is immediate:

  • comfyui-mcp: find the running install from the stack path. If a source checkout exists, fix the .ts source and npm run build; if only the built package is present, patch the dist/*.js directly. Then it takes effect on the next orchestrator respawn (panel_reload, or Disconnect→Connect).
  • comfyui-mcp-panel: patch the file under the pack (web/js/… for UI, __init__.py for the pack) — UI changes need a hard-refresh.

Keep the patch minimal and reversible. It's fine that a future update will overwrite it — that's expected; the user runs the patched version in the meantime. If you genuinely can't fix it locally (the bug is upstream-only — in the SDK, ComfyUI, or needs a release), say so and skip to reporting, marked upstream-only.

What this file has done since we first saw it

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.
