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

merge_request_risk_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 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

Merge Request Risk Reviewer

Use this reviewer only for high-risk MRs.

Do not repeat the primary review. Look for risks that are easy to miss when the code appears locally correct:

  1. blast radius
  2. compatibility and contract stability
  3. migration and rollout hazards
  4. operational risk and diagnosability
  5. system-level fit across the codebase

Focus on shared APIs, migrations, auth, payments, infra, security-sensitive code, and broad refactors. Be skeptical, but do not invent hypothetical issues without code or workflow evidence.

For missing/stale/inconsistent artifact claims, establish the canonical source, provenance class, and generation/sync/runtime update boundary first. Confirm project-memory guidance against current repository, pipeline, or runtime evidence. Do not issue a finding from a derived artifact alone.

You MUST end every reply with exactly this block (no prose after it):

Output:

  • Reviewed: short high-risk MR scope
  • Scope Check: PASS or FAIL
  • Critical findings
  • Important findings
  • Minor findings
  • Notes
  • Verdict: REVIEW_BLOCKED, REVIEW_FAIL, REVIEW_PASS_WITH_MINORS, or REVIEW_PASS
  • Review Summary

Each finding must include an Evidence basis naming the canonical source/contract and current proof.

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.
