audit-code

audit-code is a skill for Claude Code, Codex from ProsusAI/prism. It costs 27 tokens per session (2,592 once invoked), scanned A, original, Apache-2.0.

A code-architecture audit that searches skill registries for relevant recommendations and compares a codebase with them.

In plain words
What is it for?
Use it when improving a codebase’s architecture: it finds matching skills from configured or local registries, then audits the code against their recommendations.
Why use it?
It gives the review a broader source of architectural guidance instead of relying only on local opinions or conventions.

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

audit-code scanned grade A with 1 finding 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 2mo 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.

The opening of the file, as written. The whole thing — 230 lines — stays where its author put it; the contents beside it link to each section on GitHub.

When to use this skill

Use when the user wants to improve their codebase architecture by checking it against skills present in the registry. Invoked as /audit-code (Claude Code) or @audit-code (Cursor).

Configuration

  • Primary source: All configured registries in ~/.prism/registries.json (with per-registry caching and source tagging)
  • Fallback 1: Local skill-registry.json in the current project directory
  • Fallback 2: Local _analysis/extracted_skills_codebase/ skill directories
  • Authentication: REGISTRY_TOKEN environment variable (global override) or per-registry token from registries.json

Skills from multiple registries are merged and each result is tagged with [registry-name] (e.g., [team], [community]) to identify the source.

Instructions

Step 1 -- Resolve skill registry source

Read ~/.prism/skills/_shared/registry-fetch.md and follow its instructions. It resolves all configured registries with ETag caching and local fallbacks, returning a skills array where each entry is tagged with _registry.

Outcomes:

  • Valid JSON array → use as the skills list, proceed to Step 2
  • REGISTRY_EMPTY → registry reached but empty, proceed to Step 2
  • NO_REGISTRIES → no registry reachable, stop (the shared file handles the user message)

Step 2 -- Check for empty registry

If the skills array from the resolved source is empty, respond with: "No skills have been published to the registry yet." and stop.

Step 2.5 -- Check for existing analysis files

Check which analysis files exist:

for f in _analysis/full_report.md _analysis/design.md _analysis/directives.md _analysis/incidents.md; do
  test -f "$f" && echo "FOUND: $f" || echo "MISSING: $f"
done

If at least one file is found, list them and ask the user:

"Found existing analysis files in _analysis/: {list found files}

Use these for matching, or run a fresh codebase scan?"

  • Fresh scan chosen → skip to Step 3, Path B.
  • Use existing files chosen → read all found files now (see table below), then continue to Step 3, Path A.
  • No files found → skip to Step 3, Path B.

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.
