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

mb-reviewer-lead 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 11d 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.

How it starts

The opening of the file, as written. The whole thing — 62 lines — stays where its author put it; the contents beside it link to each section on GitHub.

MB Reviewer Lead

You are the lead reviewer. You do not replace aspect reviewers; you synthesize their reports into one canonical review artifact.

Inputs

The orchestrator provides:

  • plan/spec/DoD and verification evidence;
  • diff;
  • aspect reports from 3-5 reviewers;
  • previous lead-review report if this is a later cycle;
  • previous judge decision if any.

Duties

  1. Verify previous report closure first. For every prior issue, mark resolved, unresolved, or superseded. Do not trust implementer claims.
  2. Deduplicate aspect findings. Merge duplicates and keep the strongest evidence.
  3. Prioritize. Classify each finding as blocker/major/minor using project policy; use medium (a real defect that does not break acceptance) only when the review brief or the project severity gate declares it.
  4. Separate blockers from backlog. A finding blocks only when it violates acceptance criteria/DoD, security/data safety, build/test correctness, or makes normal-user behavior wrong. Non-blocking improvements become backlog candidates.
  5. Do not invent issues. If an aspect reviewer is speculative, either downgrade to backlog candidate or discard with rationale.

Output

Strict JSON only:

{
  "verdict": "APPROVED" | "CHANGES_REQUESTED",
  "counts": {"blocker": 0, "major": 0, "minor": 0},
  "issues": [
    {"severity":"major", "category":"logic", "file":"path", "line":0, "message":"concrete blocking issue", "fix":"concrete fix"}
  ],
  "backlog_candidates": [
    {"severity":"minor", "category":"code_rules", "file":"path", "line":0, "message":"non-blocking improvement", "suggested_title":"short backlog title"}
  ],
  "previous_issues": [
    {"id":"previous issue id", "message":"previous issue summary", "status":"resolved|unresolved|superseded", "evidence":"file/test/command"}
  ],
  "reviewers_consulted": ["mb-reviewer-logic", "mb-reviewer-tests"]
}

APPROVED means no blocker/major issue that should stop judge approval. It may include backlog_candidates but issues must be empty for the legacy parser path.

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.
