claude-md-audit

claude-md-audit is a skill for Claude Code from adamwstauffer/shidler. It costs 99 tokens per session (1,063 once invoked), scanned A, original, MIT.

A read-only audit of CLAUDE.md and stored project memories. It checks whether referenced files still exist, facts conflict, information is duplicated, or the memory has grown too large.

In plain words
What is it for?
Use it periodically or after major reorganisations to find stale references, contradictions, duplicated facts, and bloated memory entries.
Why use it?
Project restructures can leave outdated paths and contradictory or repeated instructions behind.

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

claude-md-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 11d 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.

CLAUDE.md + Memory Audit Skill

This repo restructures courses/ often (subject-first renames, archive moves, supersessions). Every restructure risks leaving CLAUDE.md or a memory citing a path that no longer exists. This skill catches that drift on a periodic scan rather than trying to check every commit (the most-skipped kind of rule).

Scope

The canonical instruction + memory surface:

  • CLAUDE.md (repo root) — the single project instruction file.
  • MEMORY.md — the memory index loaded each session (at ~/.claude/projects/C--GitHub-shidler/memory/MEMORY.md).
  • The memory fact filesfeedback_*.md, project_*.md, etc. in the same dir.

The four checks (run all, in order)

1. Stale references (highest value here)

Extract every path CLAUDE.md and MEMORY.md cite (backtick-quoted paths, links, table "Path" columns) and confirm each resolves in the live tree:

# pull backtick-quoted paths from CLAUDE.md, test each
grep -oE '`[^`]+`' CLAUDE.md | tr -d '`' | grep -E '/|\.md|\.json|\.xlsx|\.py' | sort -u \
  | while read p; do [ -e "$p" ] || echo "MISSING: $p"; done

Do the same for MEMORY.md and for any path a fact file names in its body. Flag each miss with the citing file:line and the likely correct path (grep the tree for the basename — a restructure usually moved it, didn't delete it).

2. Cross-file contradictions

Compare claims that appear in more than one place — CLAUDE.md vs. a memory, or two CLAUDE.md sections. Common drift: a stage count, a weight table, a "current vs. archived" status, a naming convention. Quote both sides with file:line. (Example class: CLAUDE.md's "Active Courses" table vs. a project_* memory's description of the same course.)

3. Duplication + bloat

Facts stated in full in two places should live in one home with a pointer from the other (single-sourcing). Flag: a fact duplicated between CLAUDE.md and a memory; a memory that just restates code/git history (which the memory rules say not to store); a CLAUDE.md section that has grown past its usefulness.

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.
