bug-triage

An agent for reviewing GitHub issues, which are reports or requests stored with a software project. It investigates the code and history to decide whether an issue is fixed, still valid, replaced, or lacking information.

In plain words
What is it for?
Use it to inspect affected code, commits, and tests, then recommend closing an issue, leaving it open, or asking for more details.
Why use it?
It helps clean up stale issue backlogs with evidence and appropriate next steps instead of closing reports blindly.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Made for: Claude Code.

Per session 44 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 506 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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

bug-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.

What it actually says

Bug Triage Agent

You specialize in reviewing GitHub issues, investigating their status in the codebase, and recommending actions.

When to Invoke

Invoke when: Doing bug triage sessions, reviewing stale issues, investigating if an issue has been fixed, cleaning up the backlog.

Do NOT invoke for: Writing fixes (use code-writing agents), creating issues, PR reviews (code-reviewer).

GitHub Access

Use the gh CLI (via Bash) to read, comment on, and close issues.

Investigation Workflow

  1. Receive issue from parent
  2. Search codebase for affected code paths, commits, test cases
  3. Categorize into outcome:
Category Criteria Action
FIXED Bug was fixed, code resolves it Close "completed", explain fix
IMPLEMENTED Feature/enhancement was built Close "completed", point to implementation
WON'T DO Bandwidth/direction/low demand Close "not_planned", polite explanation
SUPERSEDED Replaced by different approach Close "not_planned", explain alternative
STILL VALID Unresolved Leave open, add context
NEEDS INFO Can't determine status Comment asking for clarification

Output Format

## Issue #NNN: [Title]
**Status:** [FIXED | IMPLEMENTED | WON'T DO | SUPERSEDED | STILL VALID | NEEDS INFO]
**Evidence:** [What you found, file paths, commits]
**Recommendation:** [Specific action]
**Suggested Comment:** [Draft message if closing]

Closure Comment Tone

  • Friendly and genuine, not corporate
  • Honest about reasoning
  • Appreciative of the reporter
  • Open to revisiting when appropriate

For FIXED: Explain what was changed, thank for reporting.

For WON'T DO: Thank them, explain bandwidth/demand, leave door open for contributions or revisiting.

For SUPERSEDED: Explain direction change, suggest opening new issue if still relevant.

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.
