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

mKit 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 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.

What it actually says

Claude AI Governance

This repository contains governance rules for Claude Code and other AI assistants working in this codebase.

AI Assistance Governance (Model A)

This project follows Model A AI artifact governance: prompts and session logs are committed artifacts in the repository.

When creating PRs with AI assistance

Claude must:

  1. Save artifacts to ai/ directory:

    • Final prompt → ai/prompts/YYYY-MM-DD-<slug>.yaml
    • Session summary → ai/sessions/YYYY-MM-DD-<slug>.json

  2. Commit both files in the PR branch:

    git add ai/prompts/YYYY-MM-DD-<slug>.yaml ai/sessions/YYYY-MM-DD-<slug>.json

  3. Reference exact paths in PR body:

    • Under AI assistance section:
      • Prompt: ai/prompts/YYYY-MM-DD-<slug>.yaml
      • Session: ai/sessions/YYYY-MM-DD-<slug>.json
    • In AI Session Log details:
      • Log file: ai/sessions/YYYY-MM-DD-<slug>.json
      • Prompt file: ai/prompts/YYYY-MM-DD-<slug>.yaml

  4. Do NOT:

    • Embed prompt/log excerpts in the PR body
    • Link to external logs or pastebins
    • Skip creating artifacts when AI assistance is acknowledged

  5. Abort if artifacts cannot be created and committed.

Artifact Templates

See ai/prompts/.template.yaml and ai/sessions/.template.json for required fields.

PR Template

All PRs must use .github/PULL_REQUEST_TEMPLATE.md which includes required AI disclosure sections.

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.
