mb-red-verify

mb-red-verify is a skill for Claude Code, Codex from mrvladd-d/memobank. It costs 30 tokens per session (2,150 once invoked), scanned A, original, MIT.

An adversarial review workflow that checks whether a completed development task is correct in real use, not only whether its stated checks passed.

In plain words
What is it for?
Use it to pressure-test completed tasks, document semantic risks, and create follow-up work when serious concerns are found.
Why use it?
It can expose hidden failure modes, architectural damage, or a solution that satisfies the task record while solving the wrong problem.

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-red-verify 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 10d 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 — 171 lines — stays where its author put it; the contents beside it link to each section on GitHub.

mb-red-verify — Adversarial semantic verification

  • What it does: pressure-tests one completed TASK-* for semantic correctness, hidden failure modes, and systemic harm.
  • Use it when: a task may be locally correct yet still wrong in product/domain/architectural/operational reality.
  • Input: TASK_ID, task intent, actual change surface, tests/evidence, and only then relevant spec reconciliation.
  • Output: red-verification.md, a concise semantic-risk report, and follow-up bugs/tasks when concerns are serious.

Goal

Catch changes that are "disciplined but wrong":

  • pass acceptance criteria but solve the wrong problem
  • work locally but damage system integrity
  • overfit to the task record and ignore neighboring constraints
  • introduce architectural drift, state inconsistency, or hidden maintenance cost
  • create false confidence because the evidence surface is too narrow

This is intentionally different from existing commands

  • mb-verify checks acceptance criteria and evidence-backed task completion.
  • mb-review reviews Memory Bank quality, planning, and discipline in fresh context.
  • mb-red-verify asks: "Is this solution actually right in substance?"

Status Transition Modes

Status transitions have two modes.

Scheduler mode:

  • /autopilot and /autonomous own task status transitions.
  • Scheduler decides closure/failure/blocking eligibility.
  • /execute returns scoped implementation handoff; it does not close tasks.
  • /verify gives functional verdict/evidence; in scheduler mode it does not close/fail/block/promote.
  • /red-verify gives semantic verdict for T2/T3; in scheduler mode it does not close/fail/block/promote.
  • Scheduler must write the closure/failure/blocking decision, final task status, and evidence links to the authoritative indexed .memory-bank/tasks/TASK-*.task.json record before /mb-sync.
  • /mb-sync records/reconciles already-written task state. It does not decide closure/failure/blocking/promotion and must not sync a decision that exists only in scheduler context.
  • T0/T1 scheduler closure may use compact evidence / functional PASS according to tier policy.
  • T2/T3 scheduler closure requires VERDICT: PASS plus SEMANTIC_VERDICT: semantic-pass before scheduler marks done.
  • T3 scheduler closure also requires exact markers HUMAN_CHECKPOINT: done and ROLLBACK_RECOVERY_NOTE: present.

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.

mb-red-verify is a skill published in the GitHub repository mrvladd-d/memobank (55 stars, last pushed 3mo ago), licensed MIT. It adds 30 tokens to every session and 2,150 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
