agent-fix-bug

agent-fix-bug is a command for Claude Code from Amey-Thakur/AI-SKILLS. It costs 26 tokens per session (394 once invoked), scanned A, original, MIT.

A command brief for finding and fixing the underlying cause of a software bug. It requires the agent to reproduce the problem, make a small fix, and verify the result.

In plain words
What is it for?
Use it when a feature behaves incorrectly, to trace the failure, fix the responsible code, reproduce the original case, and run relevant tests.
Why use it?
It reduces the risk of masking symptoms with an untested patch. The process also checks that existing behavior still works and adds a regression test when the project supports tests.

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

agent-fix-bug 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 12d 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

You were invoked as a slash command. The user's input:

$ARGUMENTS

Use that input to fill this prompt's variables (take the main content, topic, or task from it; ask only if a required value is missing and not supplied), then follow the prompt exactly.


You are a coding agent. Find and fix the root cause of this bug. Do not patch the symptom.

BUG: {bug}

CONTEXT: {context}

Process, in order:

  1. Reproduce it first. Confirm you can trigger the bug and see the wrong behavior. If you cannot reproduce it, say so and ask for what you need: do not guess at a fix for a bug you have not seen.
  2. Find the root cause. Trace the actual execution path to where the behavior goes wrong. State the root cause in one sentence before fixing. Do not fix the first plausible-looking line; fix the cause.
  3. Fix it minimally. Change the least code that correctly addresses the root cause. Do not rewrite surrounding code or add unrelated changes.
  4. Prove it is fixed: reproduce the original scenario and show it now behaves correctly. Run the existing tests to confirm you broke nothing. Add a regression test that would have caught this bug, if the project has tests.
  5. Check for the same bug elsewhere: if this pattern could exist in other places, note them.

Report: the root cause, the fix and why it is correct, how you verified it, and the regression test.

Rules: be honest if the root cause is uncertain or the fix is a mitigation rather than a true fix. Do not claim it is fixed without demonstrating it.

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.
