A command for checking a codebase after a bug fix to find other places with the same bug pattern or risky context.

Use it after fixing a bug to scan related files, review high-risk matches, report likely duplicates, and optionally record a new debugging lesson.

Fixing one occurrence can leave similar defects elsewhere. This review helps identify those possible matches for inspection.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00000	$0.00445
Opus 5.5	$0.00000	$0.00178
Sonnet 5.5	$0.00000	$0.00089
Haiku 4.5	$0.00000	$0.00044

Measured 27d ago against content hash 68325230870a, method: parsed. Prices are Anthropic first-party input rates as of 2026-10-07, from the pricing page.

Security

Grade A, and why

post-fix 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 27d 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

Post-Fix Analysis Command

A bug has been fixed. Now perform a comprehensive post-fix analysis to find similar issues across the codebase.

Instructions

Understand the fix: Ask the user (or infer from recent conversation) what the bug was and what pattern caused it.
Extract the pattern: Identify:
- The code pattern that caused the bug (e.g., getInstance(), setTimeout without cleanup)
- Any risky context that makes the pattern dangerous (e.g., Tone., audioContext)
- The file that was fixed

Run the post-fix analysis tool:

cd "$(git rev-parse --show-toplevel)/app" && npx tsx scripts/post-fix-analysis.ts \
  --pattern "PATTERN_HERE" \
  --risky-context "CONTEXT_HERE" \
  --file "FIXED_FILE" \
  --symptom "SYMPTOM"

Review high-risk matches: For any matches marked as HIGH RISK:
- Read the affected files
- Determine if they have the same bug
- Report findings to the user
Update documentation if warranted: If this is a new bug pattern:
- Consider adding to src/utils/bug-patterns.ts
- Consider adding to docs/DEBUGGING-LESSONS-LEARNED.md
- Use npx tsx scripts/bug-capture.ts --interactive if detailed capture needed
Report to user:
- How many similar patterns were found
- Which are high risk and need review
- Recommendations for prevention

Example Usage

User: "I fixed a singleton bug in engine.ts where getInstance() was caching Tone.js nodes"

Response:

Run post-fix analysis with pattern getInstance and risky context Tone\.
Review matches in audio/ directory
Report findings

Arguments

$ARGUMENTS - Optional: Description of the bug that was fixed (pattern, file, symptom)

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.

post-fix is a command published in the GitHub repository adewale/keyboardia (3 stars, last pushed yesterday), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 445 tokens. 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 2026-08-31.
