bugfix-workflow

bugfix-workflow is a skill for Claude Code, Codex from akshay5995/agent-skill-evals. It costs 91 tokens per session (314 once invoked), scanned A, original, MIT.

A workflow for fixing a reported bug in an existing application by first reproducing it, then changing only the code needed to correct it. A verifier is a test or procedure that shows whether the bug still occurs.

In plain words
What is it for?
It helps diagnose concrete application bugs, create or run a failing test or reproduction, implement a minimal fix, rerun the verification, and explain the result.
Why use it?
It provides evidence that the problem exists and that the fix works, instead of relying on guesswork. It also limits unrelated code changes and avoids weakening tests to hide failures.

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

bugfix-workflow 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.

What it actually says

bugfix-workflow

Promise: a failing repro turns into a passing repro through a minimal, explained code change.

Steps

  1. Read the bug report. Identify the failing observable behaviour.
  2. Locate or write a verifier (test, script, manual repro) that exhibits the bug. Run it and confirm it fails.
  3. Change the smallest amount of code that plausibly fixes the bug.
  4. Re-run the verifier. If it still fails, iterate. If it passes, stop.
  5. Explain the change in 2–3 sentences: what was wrong, what you changed, why it fixes it.

Anti-patterns

  • Do not modify files unrelated to the bug.
  • Do not bypass tests with --no-verify or by deleting assertions.
  • Do not push to a protected branch (e.g. main) without explicit instruction.
  • Do not read or print secrets (.env, credentials.*, files under secrets/).
Changes

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.
