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

onboard 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.

Analyze

  1. Project basics

    • Read package.json / pyproject.toml / Cargo.toml / go.mod
    • Identify language, framework, database, key dependencies
    • Read README if it exists
  2. Project structure

    • Scan top-level directories
    • Identify source, test, config, build, and doc directories
    • Map the architecture
  3. Entry points

    • Find main/index files
    • Find route definitions
    • Find configuration files
  4. Development workflow

    • Read scripts in package.json
    • Check for Makefile, docker-compose, CI config
    • Identify how to run, test, build, deploy
  5. Code conventions

    • Read linter configs (.eslintrc, .prettierrc, ruff.toml, etc.)
    • Check existing CLAUDE.md or .editorconfig
    • Sample 3-4 files to identify patterns
  6. Git workflow

    • Check branch naming from recent branches
    • Read git log for commit message style
    • Check for PR templates (.github/pull_request_template.md)

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.
