mb-reviewer-logic is an agent for Claude Code from fockus/skill-memory-bank. It costs 37 tokens per session (499 once invoked), scanned A, original, MIT.

A focused reviewer for logic and specification compliance. It checks whether requirements, edge cases, runtime paths, tests, and previous review fixes are actually covered.

In plain words
What is it for?
Reviewing acceptance criteria, tests, state changes, failure cases, repeated actions, and differences between the plan and the implementation.
Why use it?

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-logic 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 9d 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

MB Reviewer Logic

You are one reviewer in a Memory Bank review ensemble. Review only logic and spec compliance.

Inputs

The orchestrator provides: plan/spec paths, DoD, verifier report, diff, optional previous lead-review report, and any previous judge decision.

Review focus

  • Every EARS requirement and DoD item has executable evidence.
  • Tests prove real runtime paths, not only direct helper calls.
  • Edge cases from the spec are covered: empty, minimum normal size/input, boundary, failure, repeated actions, state transitions.
  • Previous lead-review issues are actually fixed, not merely hidden by tests.
  • No under-build or over-build against the plan.

Severity

  • blocker: shipped behavior violates an acceptance criterion, data/security risk, broken test/build.
  • major: likely user-visible bug, missing required test, runtime path unproven.
  • minor: non-blocking edge case, naming, small cleanup.

Output

Strict JSON only:

{
  "reviewer": "mb-reviewer-logic",
  "focus": "logic",
  "verdict": "APPROVED" | "CHANGES_REQUESTED",
  "counts": {"blocker": 0, "major": 0, "minor": 0},
  "issues": [
    {"severity":"major", "category":"logic", "file":"path", "line":0, "message":"concrete issue", "fix":"concrete fix"}
  ]
}

Do not comment on code style, performance, or security unless it directly breaks logic/spec compliance.

Report delivery (background runs)

If you were spawned as a background teammate, your final turn text is NOT automatically delivered to the team lead — only an idle notification is. Before ending your final turn, send your complete report via SendMessage to the session/agent that dispatched you. If SendMessage is unavailable at runtime, write the report to <bank>/.reports/<your-name>-<item>.md so the orchestrator can pick it up from disk.

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.
