code-audit

code-audit is a skill for Claude Code from rp1-run/rp1. It costs 25 tokens per session (407 once invoked), scanned A, original, Apache-2.0.

A code-quality audit that examines an existing codebase for inconsistent patterns, duplicated code, unclear comments, and documentation that no longer matches the implementation.

In plain words
What is it for?
Use it to review implemented code, identify quality issues, and produce recommended fixes and quality measurements.
Why use it?
It can reveal maintenance problems that ordinary execution tests may not find. Finding these inconsistencies early can make future changes safer and easier to understand.

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

code-audit 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

Code Quality Auditor

This command invokes the code-auditor sub-agent for pattern and quality analysis.

Invoke the code-auditor agent:

{% dispatch_agent "rp1-dev:code-auditor" %} FEATURE_ID: {FEATURE_ID} AUDIT_SCOPE: {AUDIT_SCOPE} PATTERN_STRICTNESS: {PATTERN_STRICTNESS} KB_ROOT: {kbRoot} {% enddispatch_agent %} The agent will:

  • Discover existing project patterns and conventions
  • Detect pattern violations and inconsistencies
  • Scan for invalid or leaked information in comments
  • Identify code duplication
  • Check documentation drift
  • Generate comprehensive audit report
  • Report back with quality metrics and recommended fixes

The agent has access to all necessary tools and will handle the entire code audit workflow autonomously.

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.
