Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00666 |
| Opus 5 | $0.00000 | $0.00333 |
| Sonnet 5 | $0.00000 | $0.00133 |
| Haiku 4.5 | $0.00000 | $0.00067 |
Grade A, and why
audit-claude-md 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 9d 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 — 105 lines — stays where its author put it; the contents beside it link to each section on GitHub.
audit-claude-md Skill
Audit and refactor CLAUDE.md files to eliminate bloat, enforce context engineering best practices, and create folder-level CLAUDE.md files for complex domain-specific instructions.
Quick Start
Run the audit command to analyze all CLAUDE.md files:
/audit-claude-md
Or audit a specific file:
/audit-claude-md path/to/CLAUDE.md
What This Audits
Line Count Analysis
| File Type | Warning | Maximum |
|---|---|---|
| Feature CLAUDE.md | 100 lines | 200 lines |
| Project CLAUDE.md | 150 lines | 300 lines |
| Root CLAUDE.md | 300 lines | 400 lines |
Vague Language Detection
Prohibited patterns that degrade LLM instruction-following:
- "should probably" → Use MUST, SHOULD, or MAY
- "might want to" → Be specific or omit
- "you could" → Use imperative voice
- "consider maybe" → Decide and state clearly
- "it's good to" → Use SHOULD or MUST
- "try to" → State the requirement directly
Required Sections
Root CLAUDE.md must have:
## WHAT This Is- Purpose and scope## WHY This Approach- Rationale## HOW To Use It- Instructions
Quality Scoring
| Component | Weight |
|---|---|
| Line count | 30% |
| Vague language | 25% |
| Strong modals (MUST/SHOULD/NEVER) | 15% |
| Required sections | 15% |
| External references | 10% |
| Freshness | 5% |
Grades
- A (80-100): Excellent - Follows best practices
- B (60-79): Good - Minor improvements needed
- C (40-59): Needs Improvement - Significant issues
- F (0-39): Critical - Major refactoring required
Refactoring Recommendations
If Line Count Exceeds Maximum
- Extract deep-dive content to
docs/references/ - Keep only essential instructions in CLAUDE.md
- Add links to reference documentation
- Use progressive disclosure pattern
If High Vague Language Count
Replace uncertain language with strong modals:
- "should probably" → "MUST" or "SHOULD"
- "might want to" → "Consider" or omit
- "you could" → Direct imperative
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.

audit-claude-md is a skill published in the GitHub repository marcusgoll/Spec-Flow (92 stars, last pushed 4mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 666 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 2026-08-30.
