In plain words

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

navop-mcp AGENTS.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 2mo 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.

Project rules

  • Prefix shell commands with rtk.
  • Use TDD for CLI, MCP transport, discovery, Skill, and public output contract changes.
  • Keep navop and navop-mcp as independent executable entry points in one npm package.
  • Do not implement terminal, SSH, database, Redis, or SFTP business logic in TypeScript; call the authenticated Navop MCP runtime.
  • Keep stdout pure MCP data in navop-mcp mode.
  • Publish only exact package versions and never generate latest, wildcard, caret, or tilde launch specifications.
  • Run npm run check, npm pack --dry-run, and clean-install bin verification before release.
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.
