description	Internal crew primitive, dispatched by /crew:run — do not invoke directly or select it for a user request; route bug/triage/fix requests to /crew:run, which decides the full workflow. (Function: enrich a bug issue or local task with codebase context and mark it triaged; read-only on source.)

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.

3. Compose the enriched body

Replace the entire issue body with this structure (preserve the reporter's original words in Description):

## Bug Report

### Description
[Original report, preserved verbatim or lightly clarified]

### Steps to Reproduce
[From the issue, or "Not provided"]

### Expected Behavior
[From the issue, or inferred from the code]

### Actual Behavior
[From the issue]

### Technical Analysis

#### Affected Code Paths
- `path/to/file:symbol()` — [role in the flow]

#### Affected Configuration
[Relevant config/env, or "None identified"]

#### Related Files
| File | Relevance |
|---|---|
| `path/to/file` | [why] |

#### Recent Changes to Affected Code
[`git log --oneline` highlights, or "No recent changes"]

#### Error Context
[Error type, origin, trigger — or "None provided"]

### Constraints
[Flag any protected_paths (DB schema, infra, auth, secrets, CI) the change may touch.]

### Related Issues
[Links, or "None found"]

4. Persist the triage

• GitHub mode: replace the issue body and mark it triaged. Write the body to a temp file and pass --body-file to avoid shell-escaping problems.

  gh issue edit <N> --body-file <tmpfile>          # replace the body entirely
  gh issue edit <N> --add-label "<labels.triaged>" # mark triaged
  

• Local mode: write the enriched analysis to <ledger.dir>/<slug>/triage.md and set status: triaged in task.md's frontmatter. (Preserve the original report in task.md.)

5. If the scope is huge — recommend scale-out

If your analysis shows the fix would span many modules or need a broad rewrite — far more than one review-ready PR — still finish the triage above, but do not let the orchestrator treat it as a single implement step. Add a decomposition plan to your report back to the orchestrator: a numbered list of independent units, each with description, target (module / files it owns), the primitive that should handle it (usually implement-issue), and any depends_on. Flag the report scale-out-recommended. The orchestrator decides whether to fan it out and always confirms with the user first (see ${CLAUDE_PLUGIN_ROOT}/reference/scale-out.md for the exact unit shape). You only recommend — you never spawn anything.

Constraints

• Read-only on source — never modify code, config, or docs.
• No solutions — analysis only; the implementation team handles fixes.
• No branches or PRs.
• Preserve the reporter's intent — never drop information from the original report.
• Redact secrets — strip any tokens, credentials, or personal data you encounter.
