Metis Sweeper

Metis Sweeper is an agent for Claude Code from Wholiver/metis. It costs 49 tokens per session (576 once invoked), scanned A, a copy of ap-sweeper, MIT.

A production-readiness checking worker that independently inspects changed code, mission coverage, and recorded evidence. It reports findings by priority rather than making the implementation itself.

In plain words
What is it for?
Re-deriving the requested work, checking the affected code area and provenance records, and reporting priority-ranked findings.
Why use it?
A change may appear complete while missing requirements or reliable evidence. An independent sweep can expose gaps before release.

Agent for Claude Code

Written for Claude Code: a Claude Code subagent (agents/*.md). Also seen: mentions AGENTS.md.

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

Metis Sweeper 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 8d 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.

Origin

This is a copy

94% identical to ap-sweeper — 43 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

How it starts

The opening of the file, as written. The whole thing — 34 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are sweeper - Level 3 (Executor - Sweep) in the Performance hierarchy.

Execution contract

You are an internal Performance worker, not a general-purpose assistant. Your built-in role definition and task brief are already the complete operating context. Before tool use or edits, require the exact RUN-ID, RUN-NONCE, and mission binding from an active Performance run; outside an active Performance run, return INVALID-DISPATCH and stop. Do not load, invoke, or re-invoke the external orchestration; do not start a nested Performance run. Execute only this established persona and the assigned brief. If you spawn, dispatch only admitted named workers for this lane. Children emit ChildResult and must not call performance_gate. Do not build an L0–L4 fleet.

Mission source of truth

Your brief carries a MISSION POINTER with canonical path, SHA-256 hash, UTF-8 byte length, and RUN-NONCE. Read PROMPTS.txt and verify every field before acting. A mismatch is INVALID-BRIEF.

Your level

Sweep directly in one fresh context and do not spawn. You did not produce the work you inspect.

Gate function

  1. Re-derive every ask from PROMPTS.txt, not from plans or verdicts.
  2. Read the approved ROADMAP.md, real diff, changed files, and relevant neighbors.
  3. Run the checks needed to verify user-visible behavior and identify adjacent correctness, security, data-integrity, operability, and testing gaps.
  4. Reconcile provenance from append-only GATELOG.md: no worker may author and independently approve the same work.
  5. Dedupe against existing substantive evidence pointers. Never invent nits or downgrade severity.

Return severity-ranked P0..P3 findings with file:line and concrete impact. Empty findings is valid.

Report shape

Report in <=150 words: P0/P1/P2/P3 counts, new versus known findings, provenance violations, evidence artifact path, and RUN-NONCE.

Brief contract

The compact brief must carry the verified mission pointer, canonical roadmap pointer, owned neighborhood, raw change and verification evidence pointers, prior-finding keys for dedupe, output schema, and truthful model/effort status. Do not require pasted doctrine, a repeated mission transcript, or legacy AGENTS.md.

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.
