failure-triage

failure-triage is a skill for Claude Code from yeaight7/agent-powerups. It costs 25 tokens per session (562 once invoked), scanned A, original, Apache-2.0.

A failure-triage guide for classifying an unknown CI or production failure before choosing a debugging method.

In plain words
What is it for?
Use it to distinguish build, logic, infrastructure, and intermittent failures, inspect first-party stack frames, and check recent changes before proceeding.
Why use it?
It prevents starting an unnecessarily deep investigation and helps identify the affected subsystem, failure type, and likely scope.

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

failure-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 1mo 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 — 64 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Purpose

Before diving deep into a stack trace or spending hours reproducing a bug, triage it to determine the blast radius, subsystem, and debugging approach. Do not start writing fixes until you have explicitly stated your triage hypothesis and confirmed the category.

When to Use

  • A CI job or production system is failing and the cause is unknown
  • A bug report arrives without a clear owner or subsystem
  • Before choosing between deep debugging, bisecting, or reproduction work

Inputs

  • The failure signal: stack trace, CI log excerpt, or error report
  • The repo, for recent-change inspection

Workflow

  1. Categorize the failure:

    • Syntax/Build error — fails before running
    • Logic error — runs, but produces wrong output
    • Infrastructure/Environment error — network timeout, missing DB table
    • Flaky/Non-deterministic error — fails sometimes
  2. Locate the origin. Scan the stack trace. Ignore framework/library internals. Find the highest frame that belongs to the first-party application code:

    # surface first-party frames (adjust the path filter to the repo layout)
    grep -n "src/" stacktrace.txt | head -20
    
  3. Check recent changes. Most bugs are in the newest code:

    git log -n 5 --oneline
    git diff HEAD~5 --stat
    git log -n 10 --oneline -- <suspect-file-or-dir>
    
  4. Formulate a hypothesis. State clearly: "I suspect this is an environment error caused by missing configuration, originating in src/config.ts."

Output

  • A stated category (build / logic / environment / flaky)
  • The suspected origin file or subsystem
  • An explicit triage hypothesis, before any fix is attempted

Verification

  • Failure assigned to exactly one category
  • Origin frame identified in first-party code, not framework internals
  • Recent commits checked for related changes
  • Hypothesis stated explicitly before any fix was written

Failure Modes

  • Fixing before triaging — patching the symptom at the crash site while the root cause lives elsewhere.
  • Blaming the framework — the highest first-party frame is the lead; library internals rarely are.
  • Skipping recent history — git log is the cheapest triage tool available; check it before anything expensive.

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.

failure-triage is a skill published in the GitHub repository yeaight7/agent-powerups (6 stars, last pushed 19d ago), licensed Apache-2.0. It adds 25 tokens to every session and 562 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-09-14.
