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

genblaze 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

Genblaze — Claude Code Config

  • Follow AGENTS.md at all times
  • Read order: README.md → ARCHITECTURE.md → AGENTS.md → relevant feature doc
  • Plans go in docs/exec-plans/active/
  • Test commands: make test (full-suite gate), /test-package <name> (one package), /test-package changed (only changed packages)
  • Quick single-file run: cd libs/core && pytest tests/unit/<file>.py -v
  • Lint: make lint. Python edits are auto-formatted via .claude/hooks/auto-format.sh.
  • Always run make test before considering work complete
  • Update docs in the same PR as code changes
  • Keep diffs minimal — only change what's needed
  • Adding a new connector: use /scaffold-provider. Before tagging a release: run make pre-release and read RELEASING.md. After publish: make post-release VERSION=<umbrella-version>. Auditing docs freshness: /verify-docs.
  • Release flow: tag name follows the CHANGELOG wave header (v0.3.0), not any single package's version. Workflow at .github/workflows/release.yml triggers on GitHub Release creation; workflow_dispatch runs a TestPyPI dry-run.
  • CI policy: Dependabot PRs run NO CI. Every job in .github/workflows/ci.yml and security.yml is guarded by if: ${{ github.actor != 'dependabot[bot]' && github.event.pull_request.user.login != 'dependabot[bot]' }}. When adding a job to any pull_request-triggered workflow, copy that same guard onto it, otherwise Dependabot PRs would start running CI again. release.yml has no pull_request trigger, so it needs no guard.
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.
