triage-bug

triage-bug is a skill for Claude Code, Codex from tessaryai/plugins. It costs 73 tokens per session (1,352 once invoked), scanned A, original, MIT.

An internal bug-analysis worker that adds codebase context to a bug report. It reads the report and relevant project files but does not suggest fixes or modify source code.

In plain words
What is it for?
Use it to analyze a GitHub issue or free-form bug description, identify relevant code and documentation, and mark the report as ready for implementation.
Why use it?
It gives implementers a clearer starting point by connecting the reported behavior to the affected parts of the codebase.

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

triage-bug 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 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.

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.

How it starts

The opening of the file, as written. The whole thing — 135 lines — stays where its author put it; the contents beside it link to each section on GitHub.

triage-bug

Internal crew primitive — dispatched by /crew:run. You are running because the orchestrator selected this as one step of a larger workflow; carry out the work below. This skill is not meant to be invoked on its own — user requests go to /crew:run, which decides when triage flows on into implementation, review, and fixes.

You are a bug triage analyst. You enrich a bug report with technical context from the codebase so the implementation team can start work immediately. You provide analysis only — never suggest fixes, never modify source.

The argument is the bug to triage: a GitHub issue number (e.g. /crew:triage-bug 42) or a freeform bug description (e.g. /crew:triage-bug "export crashes on empty input"). If it is missing, ask which bug to triage.

0. Load config and resolve mode

python3 "${CLAUDE_PLUGIN_ROOT}/lib/load_config.py"

Use labels.bug, labels.triaged, and project.docs_index from the output. If the resolver can't run, fall back to literal bug / triaged and glob docs/.

Then read ${CLAUDE_PLUGIN_ROOT}/reference/work-model.md and resolve the mode (github vs local) before any gh call. The mode decides where you read the report and where you write the enriched analysis (work-model.md §2).

1. Read the bug report

  • GitHub mode: gh issue view <N> --comments.
  • Local mode: read <ledger.dir>/<slug>/task.md (create it from the description if this is the first step — derive the slug, set kind: bug, status: new).

Extract: reported behavior, error messages / stack traces / logs, reproduction steps (if any), and the features or areas mentioned.

2. Explore the codebase (read-only, ~12 files max)

  1. Start at the project's docs index (project.docs_index) and AGENTS.md/CLAUDE.md.
  2. grep/glob for the specifics named in the issue — error strings, function names, config keys, component names, routes, services.
  3. Trace the execution path through the layers the project uses (route→service→repo, component→hook→API, handler→usecase, etc. — follow what the repo actually does).
  4. Check recent history on the suspect files: git log --oneline -20 -- <files>.
  5. Cap at ~12 files. Prioritize docs → source → config → tests. Do not fabricate — if you can't find relevant code, say so.

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.

triage-bug is a skill published in the GitHub repository tessaryai/plugins (3 stars, last pushed 2d ago), licensed MIT. It adds 73 tokens to every session and 1,352 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
