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 | $0.03744 | $0.03744 |
| Opus 5 | $0.01872 | $0.01872 |
| Sonnet 5 | $0.00749 | $0.00749 |
| Haiku 4.5 | $0.00374 | $0.00374 |
Grade C, and why
echook CLAUDE.md scanned grade C with 2 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 today.
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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

How it starts
The opening of the file, as written. The whole thing — 84 lines — stays where its author put it; the contents beside it link to each section on GitHub.
echook — AI Operator Guide
v6.5.1 · Multi-platform: Claude Code (plugin) · Cursor (native + auto-bridge) · Codex (plugin + native). Source-of-truth for every capability is
audio-hooks manifest(live JSON, includespointers,editor_targets,supported_editors). This file is orientation only.
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.
