Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md. Also seen: names the AskUserQuestion tool; mentions Claude Code.

This is TongilKim/ClauTunnel's own configuration. It tells Claude Code how to work on ClauTunnel itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything ClauTunnel configures →

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

ClauTunnel CLAUDE.md scanned grade A with 1 finding 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 9d 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.

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