Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md.

This is v0idw4lker/trustmcp's own configuration. It tells Claude Code how to work on trustmcp 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 trustmcp 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

trustmcp 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 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.

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

Writing style

  • Never use em dashes (—) or en dashes (–), anywhere: code, docs, commit messages, PR descriptions, issue text. Use a comma, a period, or parentheses instead, whichever fits the sentence.
  • Write in a direct, confident, human voice. No AI-typical filler ("furthermore", "it's important to note", "leverage", "seamless", "robust", "cutting-edge", "dive in", "unlock", "game-changer"), no perfectly balanced three-item lists, no repetitive "X does this, Y does that" sentence rhythm. Vary sentence length like a real person writing.
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.
