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

english-only 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 5d 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

English only — repository (binding)

All project artifacts in this repo must be English:

  • CLAUDE.md, .cursor/rules/*.
  • docs/** (requirements, SDD, architecture, OpenAPI descriptions and examples).
  • Source comments.
  • User-visible UI copy (also requires i18n — see i18n-mandatory.mdc).
  • Commit messages.
  • READMEs, config / doc strings you add or edit.

Forbidden

Adding Chinese or other natural languages to those artifacts.

Allowed

  • Conversation language in chat may follow the user — say what you want in chat. Anything written into the codebase stays English.
  • Legal quotes / verbatim user content that must be preserved in another language — requires explicit user approval.

Enforcement

  • npm run check:terminology — terminology guard on product surfaces (CI gate).
  • Code review — reviewer rejects non-English content.

What this protects

  • Globally distributable codebase.
  • Tool / search / lint compatibility (most tools assume English identifiers).
  • Predictable diff readability for international contributors.

Skipping this rule requires explicit user approval in chat (e.g., "we need to embed a Chinese legal quote here").

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.
