bug-capture

bug-capture is a skill for Claude Code, Codex from tmusser/ai-engineering-skills. It costs 14 tokens per session (244 once invoked), scanned A, original, MIT.

A format for recording discovered software bugs in a BUGS.md file. It preserves what happened, what should happen, how to reproduce it, and how it was checked.

In plain words
What is it for?
Documenting observed and expected behavior, reproduction steps, affected files, likely causes, status, verification commands, and resolutions.
Why use it?
It keeps bug details available after the current conversation and gives another developer enough information to investigate or verify the issue.

Written for no agent in particular: nothing here depends on one.

Good fit Documenting observed and expected behavior, reproduction steps, affected files, likely causes, status, verification commands, and resolutions.

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

bug-capture 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 8d 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

Bug Capture

Purpose

Preserve discovered bugs as artifacts.

When to use

Use when a bug is found, whether or not it is fixed in the current session.

Inputs

  • Observed behavior
  • Expected behavior
  • Reproduction steps
  • Affected files
  • Verification command

Workflow

  1. Create or update BUGS.md.
  2. Add a bug title.
  3. Record observed and expected behavior.
  4. Write reproduction steps.
  5. List affected files.
  6. Add hypothesis and status.
  7. Record verification command.
  8. Add resolution if fixed.

Outputs

  • BUGS.md entry with bug title, observed behavior, expected behavior, reproduction steps, affected files, hypothesis, status, verification command, and resolution if fixed

Stop conditions

  • The bug is captured well enough for another session to reproduce.
  • The issue is not a bug and should become a decision or task instead.

Anti-patterns

  • Leaving bug knowledge trapped in chat history.
  • Recording "broken" without reproduction steps.
  • Closing a bug without verification evidence.
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.
