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 | $0.00071 | $0.01744 |
| Opus 5 | $0.00036 | $0.00872 |
| Sonnet 5 | $0.00014 | $0.00349 |
| Haiku 4.5 | $0.00007 | $0.00174 |
Grade A, and why
claude-md-management 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 10d 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 — 171 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md Management
Purpose of CLAUDE.md
Treat CLAUDE.md as the entry point for Claude Code to understand a project. It is the first file read when Claude Code enters a repository. Write it as a concise project brief that enables Claude Code to work effectively without reading every file in the codebase.
CLAUDE.md is not documentation for humans. It is a configuration and context file for Claude Code. Optimize for machine comprehension, fast orientation, and actionable instructions.
File Placement
Place CLAUDE.md files at the appropriate scope:
- Repository root (
./CLAUDE.md): Project-wide rules, tech stack, conventions, and documentation pointers. This is the primary file and is always read first. - Subdirectory (
./packages/api/CLAUDE.md): Module-specific rules that apply only when working within that directory. Use for monorepos or projects with distinct subsystems. - User home (
~/.claude/CLAUDE.md): Personal preferences and global rules that apply across all projects. Use for universal coding style preferences, commit conventions, or agent configurations.
When multiple CLAUDE.md files exist, Claude Code merges them with this priority: user home (lowest) < repository root < subdirectory (highest). Subdirectory rules override root rules when working in that directory.
What to Include
Structure every CLAUDE.md with these sections. Include only sections that are relevant to the project.
Project Overview
Provide a brief description of what the project is and does. Keep it to 2-3 sentences. Include the primary purpose, the target users or audience, and the deployment model.
## Project Overview
Multi-tenant SaaS platform for managing mobile application deployments. Serves enterprise customers with role-based access, audit logging, and automated build pipelines. Deployed on AWS with Kubernetes.
Tech Stack
List the core technologies with their roles. Be specific about versions only when the version matters for compatibility or behavior.
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.

claude-md-management is a skill published in the GitHub repository doancan/mags (3 stars, last pushed 7mo ago), licensed MIT. It adds 71 tokens to every session and 1,744 once invoked, about $0.0004 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 2026-08-31.
