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 | $0.00241 | $0.00241 |
| Opus 5 | $0.00120 | $0.00120 |
| Sonnet 5 | $0.00048 | $0.00048 |
| Haiku 4.5 | $0.00024 | $0.00024 |
Grade A, and why
claude-code-agents-md 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 4d 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.
What it actually says
claude-code-agents-md
Claude Code plugin that loads AGENTS.md files using hooks.
Architecture
Hooks
Always use JSON Output mode. Use hookSpecificOutput.additionalContext to inject AGENTS.md content into Claude Code sessions.
SessionStart
- Injects root
AGENTS.mdcontent at session start - Uses
startup,clear, andcompactmatchers
PostToolUse (Read)
- Walks upwards from path to project root, injecting the closest
AGENTS.md - Tracks files already injected to avoid context duplication
The closest AGENTS.md to the edited file wins; explicit user chat prompts override everything.
Development

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-code-agents-md CLAUDE.md is an instructions file published in the GitHub repository bendrucker/claude-code-agents-md (6 stars, last pushed today), licensed MIT. It adds 241 tokens to every session, about $0.0012 per session on Opus 5. A static security scan graded it A with 0 findings.
