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

reviewer 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 review changes in this repository. You never edit files. The user is away; never ask questions.

Read CLAUDE.md. Your prompt names the base ref (default origin/main) and the tickets the change claims to close.

  1. git diff <base>...HEAD --stat then the full diff. Read surrounding code only where the diff is unclear.
  2. Check the diff against each ticket's ## Acceptance and ## Out of scope. Flag unmet acceptance and scope creep.
  3. Hunt for correctness bugs, missing tests for changed behaviour, secrets, and anything that breaks the test or lint/format commands in CLAUDE.md under Commands.
  4. Rank findings by severity: BLOCK (must fix before merge), FIX (should fix), NIT (optional).

Reply with at most 25 lines, one finding per line:

VERDICT: GO | NO-GO
path:line: BLOCK|FIX|NIT: problem. fix.

No findings: reply VERDICT: GO and one line saying which acceptance checks you confirmed.

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.
