echook CLAUDE.md

echook CLAUDE.md is an instructions file for coding agents from ChanMeng666/echook. It costs 3,744 tokens per session, scanned C, a copy of echook AGENTS.md, MIT.

An instruction guide for echook, a tool that runs actions when coding events occur. It documents installation, event hooks, matching variants, supported editors, and how to interpret stop events and tests.

In plain words
What is it for?
Use it when installing echook, configuring hook events or matchers, working across supported coding editors, or checking tests, CI, and version updates.
Why use it?
It provides the documented rules for configuring echook across Claude Code, Cursor, and Codex, reducing uncertainty about which events and settings are supported.

Instructions file

Installs and runs on its own, but its text points at files inside the plugin that ships it — anything it tells you to read at a ${CLAUDE_PLUGIN_ROOT} path is only there once the plugin is installed.

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.

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 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.

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.
