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 A, and why

ClaudeWatch 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 1mo 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.md

Shared agent guidance lives in AGENTS.md, imported below. This file holds Claude Code–specific bits.

@AGENTS.md

Commands

# Run tests
bash tests/test-watchdog.sh

# Test the plugin locally
claude --plugin-dir .

Hook protocol

Claude Code passes tool invocations as JSON on stdin. The hook outputs {"hookSpecificOutput":{"hookEventName":"PreToolUse","permissionDecision":"deny|ask","permissionDecisionReason":"..."}} to reject or prompt the user, or nothing (allow). Exit code must always be 0 (see AGENTS.md "Core contracts").

Changes

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.
