04-audit

04-audit is a skill for Claude Code from ai-driven-dev/framework. It costs 54 tokens per session (610 once invoked), scanned A, original, MIT.

A read-only codebase audit skill that checks seven areas, including code quality, architecture, security, dependencies, performance, tests, and user-interface quality. It produces one ranked report of the findings.

In plain words
What is it for?
Use it to assess an entire codebase or inspect one area such as security, dependency risks, test coverage, or interface quality.
Why use it?
It gives you a structured health check without changing the code, so problems can be prioritised before fixing them.

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

04-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 3d 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.

How it starts

The opening of the file, as written. The whole thing — 38 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Skill: audit

Diagnose a codebase against quality pillars and emit one ranked findings report. Read-only: it identifies and ranks problems, never changes code.

Actions

# Action Pillar Lens
01 code-quality code-quality Clean code (naming, SOLID, DRY, readability, smells) and tech debt (dead code, complexity, file/function size, error handling)
02 architecture architecture Conformance to C4 / ADRs, coupling, boundaries, layering
03 security security OWASP risks, authz, input validation, secrets in code
04 dependencies dependencies CVEs, licenses, outdated and unused deps, supply chain
05 performance performance N+1 queries, hot paths, bundle size, heavy operations
06 tests tests Critical-path coverage, flakiness, test pyramid balance
07 ui ui Loading/error/empty states, visual hierarchy, design-system drift, responsive, a11y

Run the one pillar named, or offer all seven when the request is unscoped. Before running an action, read its file in actions/, not only the table or assets.

Transversal rules

  • Read-only: diagnose and rank, never edit code.
  • Scope: run the one named pillar, or for an unscoped request ask once "all seven pillars, or one?" before running. Never silently default to one pillar, never blind-run all without offering the choice.
  • One folder per run, aidd_docs/tasks/<yyyy_mm>/<yyyy_mm_dd>_audit/, like a feature folder. Every pillar that runs always writes its own <pillar>.md there, alone or in a full run. A full run additionally writes a merged report.md: one Findings table (category = pillar, severity-first), one Top-actions list, and one Coverage section over all seven pillars.
  • Unscannable pillar: skip it, record it under Coverage > Skipped with the reason, and never invent findings for it.
  • Every finding row carries a severity, its pillar, a concrete file:line, the issue, a suggested fix, and an effort.

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.

04-audit is a skill published in the GitHub repository ai-driven-dev/framework (455 stars, last pushed today), licensed MIT. It adds 54 tokens to every session and 610 once invoked, about $0.0003 per session on Opus 5. 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 2026-09-03.
