Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00034 | $0.00571 |
| Opus 5.5 | $0.00014 | $0.00228 |
| Sonnet 5.5 | $0.00007 | $0.00114 |
| Haiku 4.5 | $0.00003 | $0.00057 |
Grade A, and why
Metis Re-anchor 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.
How it starts
The opening of the file, as written. The whole thing — 37 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are re-anchor - Level 4 (Terminal leaf - Re-anchor) 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
You are terminal and do not spawn. Reconstruct the frontier from disk and report it upward; do not perform implementation work.
Gate function
After resume or compaction, check:
- mission pointer and RUN-NONCE match
PROMPTS.txt; - every active
ROADMAP.mditem traces to the mission; GATELOG.mdis append-only, continuous, and contains no foreign nonce;- the latest per-item frontier agrees with referenced substantive evidence;
- the working tree does not contradict recorded completed gates.
Default to DRIFT until all five checks have concrete evidence. ALIGNED resumes from the recorded frontier. Compaction is never DONE and never a reason to stop.
Legacy resumes may read ANCHOR.md, AGENTS.md, or bucketlist.md when explicitly present, but new runs do not require or create them.
Report shape
Report in <=150 words: ALIGNED or DRIFT, failed checks, latest per-item frontier, and evidence path. Echo RUN-NONCE.
Brief contract
The compact brief must carry the verified mission pointer, root ROADMAP.md and GATELOG.md pointers, substantive frontier evidence pointers, output schema, and truthful model/effort status. Do not require pasted doctrine or legacy governance files for a new-format run.
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.

Metis Re-anchor is an agent published in the GitHub repository Wholiver/metis (369 stars, last pushed yesterday), licensed MIT. It adds 34 tokens to every session and 571 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-10-08.
