fixbugs

fixbugs is a skill for Claude Code from TweekFawkes/prompts. It costs 153 tokens per session (642 once invoked), scanned A, original, Unlicense.

A recurring bug-fixing workflow that reads Markdown bug reports from a specified open-bugs folder, fixes them, and reruns the command that exposed each failure.

In plain words
What is it for?
Use it in a separate coding session to process bug reports oldest first, reproduce failures, apply small fixes, verify the results, and repeat at a chosen interval.
Why use it?
It keeps checking for newly reported test failures, so known bugs can be worked through without manually restarting the process each time.

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

fixbugs 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

/fixbugs — auto-fix the bug reports filed by the auto-testing rotation

This is the standing wrapper for the /loop prompt that runs after each auto-testing pass. Instead of pasting that long string by hand, the user runs /fixbugs and the agent starts the same recurring fix loop.

Context

  • The PRODUCER is whatever writes bug reports — a test runner, a scheduled test rotation, or CI. It runs the test suite(s) and writes every failure as a *.md bug report into z_tickets/open_bugs/ (each report's "Context" section names the exact command that reproduces the failure).
  • This skill is the CONSUMER: it watches that directory and fixes the reports.
  • Run /fixbugs in a separate CLI session from the producer so the two sessions don't fight over the same working tree / branch.

What to do

  1. Parse the argument after /fixbugs as $INTERVAL (integer seconds). If absent or invalid, use 300. Enforce a floor of 60.

  2. Invoke the built-in loop skill with exactly this prompt, substituting $INTERVAL:

    /loop --interval $INTERVAL Scan z_tickets/open_bugs/ for *.md bug reports (skip files starting with _ or .). For each bug, oldest first: read it, reproduce the failure using the exact command in its Context, find and fix the root cause (smallest change that works), then re-run that exact command to verify it is green. On success, move the file to z_tickets/closed/ and commit on a branch. If you cannot fix or reproduce it, leave the file in place, append a short "Investigation" note, and move on. If z_tickets/open_bugs/ is empty, do nothing this iteration.
    
  3. Honor the project's guardrails while fixing: smallest change that works, never mix formatting with behavioral changes, never --no-verify without approval, and keep each fix on its own branch. Production is gated — do not deploy to prod as part of a fix without explicit approval.

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.
