github-issue-triage

A workflow for reviewing GitHub issues by checking their claims against the code, project plans, and product direction before writing a structured comment.

In plain words
What is it for?
Use it to inspect an issue, verify relevant code, judge whether the request fits the roadmap, and post findings, corrections, a recommendation, and test steps.
Why use it?
It helps separate real, current problems from outdated reports or misunderstandings, while keeping fixes from being started before the issue is properly assessed.

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

github-issue-triage scanned grade A with 0 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 yesterday.

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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

GitHub Issue Triage

Assess a GitHub issue by verifying its claims against actual code, checking fit against product vision, and leaving a structured comment with findings, corrections, and a test plan. This skill assesses and comments — it does not implement fixes. Fixes follow a separate deliberate step per this repo's Recommendation Assessment mandate in CLAUDE.md.

The Prompt (canonical form)

Triage issue #N. Start by fetching the full issue details (title, body, comments, labels, linked PRs). Then verify every factual claim in the issue against the actual running code — grep the relevant source, read the actual files/lines, and where feasible run the relevant code path (in a scratch/sandboxed way) to confirm it's real, not stale, not a misunderstanding. Check the ask against roadmap/vision docs (ROADMAP.md, ARCHITECTURE.md, DECISIONS.md, MANIFEST.md) and note whether it's a scoped fix vs. a bigger direction-setting ask needing human scoping. Draft and post a gh issue comment with: confirmed findings with evidence, corrections to stale/wrong claims, a recommendation per CLAUDE.md's Recommendation Assessment mandate, and concrete test/verification steps for the fix. Report what you found and what you posted.

Procedure

1. Fetch the issue

Run gh issue view <n> --json title,body,comments,labels,linkedPullRequests. Extract:

  • Title and body (claims to verify)
  • All comments (context, earlier findings, clarifications)
  • Labels (priority, type, status signals)
  • Linked PRs (related work, partial fixes, predecessor context)

2. Verify every factual claim against running code

This is the hardest step and the highest leverage. Do not trust the issue's prose — verify against the source.

For each claim:

  • File changes: Does the file exist? test -e <path>. Read it and check the actual line/section.
  • Behavior claims: Grep for the relevant code path. If feasible, run it in a scratch/sandboxed context (e.g., a test, a manual script in a temp directory, a clone of this repo or the repo's dependency) to observe actual behavior.
  • "Already fixed" archaeology: Run git log --all -p --grep=<keyword> or git log --all -S<string> to check whether a claimed-broken thing was already fixed by a later commit on a different branch or after the issue was filed.
  • Misunderstandings: If the claim rests on a false premise (wrong file path, misread config, older API surface), note that explicitly.

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.
