triage-issue

triage-issue is a skill for Claude Code, Codex from Shiven0504/claude-skills-collection. It costs 65 tokens per session (848 once invoked), scanned A, a copy of triage-issue, MIT.

A workflow for investigating a reported software bug, finding its underlying cause in the code, and opening a GitHub issue with a test-driven development (TDD) plan. TDD means writing tests that describe the fix before changing the code.

In plain words
What is it for?
Use it to trace a bug through a codebase, review related code and tests, check relevant file history, and prepare a GitHub issue for fixing it.
Why use it?
It turns a vague bug report into a documented diagnosis and an actionable fix plan. This reduces guesswork about where the problem comes from and how to verify the repair.

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-issue 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 11d 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.

Triage Issue

Investigate a reported problem, find its root cause, and create a GitHub issue with a TDD fix plan. This is a mostly hands-off workflow - minimize questions to the user.

Process

1. Capture the problem

Get a brief description of the issue from the user. If they haven't provided one, ask ONE question: "What's the problem you're seeing?"

Do NOT ask follow-up questions yet. Start investigating immediately.

2. Explore and diagnose

Use the Agent tool with subagent_type=Explore to deeply investigate the codebase. Your goal is to find:

  • Where the bug manifests (entry points, UI, API responses)
  • What code path is involved (trace the flow)
  • Why it fails (the root cause, not just the symptom)
  • What related code exists (similar patterns, tests, adjacent modules)

Look at:

  • Related source files and their dependencies
  • Existing tests (what's tested, what's missing)
  • Recent changes to affected files (git log on relevant files)
  • Error handling in the code path
  • Similar patterns elsewhere in the codebase that work correctly

3. Identify the fix approach

Based on your investigation, determine:

  • The minimal change needed to fix the root cause
  • Which modules/interfaces are affected
  • What behaviors need to be verified via tests
  • Whether this is a regression, missing feature, or design flaw

4. Design TDD fix plan

Create a concrete, ordered list of RED-GREEN cycles. Each cycle is one vertical slice:

  • RED: Describe a specific test that captures the broken/missing behavior
  • GREEN: Describe the minimal code change to make that test pass

Rules:

  • Tests verify behavior through public interfaces, not implementation details
  • One test at a time, vertical slices (NOT all tests first, then all code)
  • Each test should survive internal refactors
  • Include a final refactor step if needed
  • Durability: Only suggest fixes that would survive radical codebase changes. Describe behaviors and contracts, not internal structure. Tests assert on observable outcomes (API responses, UI state, user-visible effects), not internal state. A good suggestion reads like a spec; a bad one reads like a diff.

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.
