mb-execute

mb-execute is a skill for Claude Code, Codex from mrvladd-d/memobank. It costs 31 tokens per session (1,648 once invoked), scanned A, original, MIT.

An implementation handoff workflow for completing one tracked development task with defined procedures, local checks, evidence, and a final handoff.

In plain words
What is it for?
Use it to implement a scoped task, run its required checks, record evidence, and pass the result to the process that manages task status.
Why use it?
It gives a repeatable path from reading a task to verifying the change without letting the implementation step decide whether the task is closed.

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-execute 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 5d 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.

mb-execute - Implementation Handoff

Purpose

mb-execute implements one scoped JSON task. It is not a mini-scheduler and it does not own task closure. Flow: read task -> minimal preflight -> protocol -> implement -> local gates -> evidence -> handoff.

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.

Manual mode:

  • Expected T0/T1 simple flow: /execute -> /verify for one TASK.
  • Manual closure is allowed only when an explicit closure owner exists.
  • explicit standalone owner means either the user directly asked the current top-level agent to close the task, or the top-level agent/orchestrator explicitly runs a manual workflow for one TASK and records that it owns closure. Subagents/worker prompts do not silently become closure owners.
  • /verify PASS may mark T0 / T1 status: done only when explicit closure ownership is present and completed evidence has been written to the task record verify field and the compact/full protocol required by tier.
  • If explicit closure owner is absent, /verify records VERDICT: PASS, evidence, and a closure recommendation, leaves status unchanged, and tells the scheduler/owner to close.
  • T2 / T3 manual closure requires /verify PASS plus /red-verify / mb-red-verify SEMANTIC_VERDICT: semantic-pass before status: done or /mb-sync; if semantic-pass is absent, leave closure pending or blocked, not done.
  • semantic-concern in manual mode means do not trust the existing done state without human review / follow-up.
  • Do not mix scheduler mode and manual mode inside one task run.
  • No persisted mode field is used.

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-execute is a skill published in the GitHub repository mrvladd-d/memobank (55 stars, last pushed 3mo ago), licensed MIT. It adds 31 tokens to every session and 1,648 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.
