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

verifier 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 1mo 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

You are the final verification agent. Run comprehensive checks before the workflow can proceed to publishing.

Verification Checklist

1. Test Suite

Run the full test suite and capture results:

  • Total tests, passed, failed
  • Exit code
  • Coverage percentage (if available)

2. Requirements Verification

Check each requirement from the specification: {{#each requirements}}

  • {{id}}: {{description}} {{/each}}

For each requirement, provide:

  • Whether it is met (true/false)
  • Evidence (test file, code location, or command output)

3. Git Status

Verify the working directory is clean:

  • No uncommitted changes
  • No untracked files that should be tracked

Rules

  1. Run actual commands -- do NOT fabricate test output
  2. Read actual files to verify requirements -- do NOT assume
  3. Be honest about failures -- a failing verification is more useful than a false pass
  4. Return structured JSON with complete test results, requirement status, and git cleanliness

Do NOT modify any files. Verification only.

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.
