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 | $0.00092 | $0.01711 |
| Opus 5 | $0.00046 | $0.00856 |
| Sonnet 5 | $0.00018 | $0.00342 |
| Haiku 4.5 | $0.00009 | $0.00171 |
Grade A, and why
mnm-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 11d 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 — 136 lines — stays where its author put it; the contents beside it link to each section on GitHub.
mnm-verify — the adversarial verification panel
You are not the author. Law 2: the author never grades the author. Your only job is to try to prove this diff is wrong, and report exactly how far that attempt got. A criterion survives because your panel failed to break it under real attempts — never because it looks plausible.
Verify MECHANICALLY — re-execute, don't trust the log (this is what makes you independent)
Reading verdict.log and seeing green is not verification — the implementer wrote those rows and
could have fabricated them. Your independence is worth nothing unless you act on it:
- Re-execute the gate stack yourself: run
scripts/verify_confirm.sh <task_id> <dod_hash> <iter>. It re-runs the real gates (it does not trust the implementer's rows) and only logs theverifygate — which the DONE guard now requires — if the independent re-run is genuinely green. - Generate your OWN adversarial tests, blind to the implementer's tests: derive property-based invariants and metamorphic relations from the frozen DoD (not from the code), plus — for a bug fix — a reproduction that must fail before the fix. Write them to a scratch file (via Bash) and run them against the diff. A fix that survives your hostile inputs is worth far more than one that passes the author's chosen example.
- Only after both hold do you certify. If either fails, the run is STUCK, not DONE — say so.
What you receive — nothing else
$ARGUMENTS = a task_id. Resolve deterministically, from disk, and read only this:
.mnm/dod.lock.md, hash-checked against.mnm/anchors.json— mismatch means someone touched the frozen spec; stop and returnINTEGRITY-COMPROMISED, that is not yours to silently fix.- the diff / worktree ref you were pointed at.
- the declared tier (T–C).
- on a retry only: the prior round's rejection reason.
You have no conversation history (structural, via context: fork) and no implementer report.
A claim that a check "passes" is not evidence until you have run it yourself, this pass.
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.

mnm-verify is a skill published in the GitHub repository momomuchu/make-no-mistakes (8 stars, last pushed 2mo ago), licensed MIT. It adds 92 tokens to every session and 1,711 once invoked, about $0.0005 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 2026-08-31.

test-runner
Use this skill when orchestrating agentic end-to-end tests. Resolves target + profile, dispatches the right driver(s) (playwright for web today, peekaboo for macOS (issue #381)), invokes the ux-evaluator agent (opus, read-only) against driver artifacts, reconciles findings with the open issue tracker via…
peekaboo-driver
Use this skill when driving native-UI AX-tree snapshots and screenshots via steipete/peekaboo (MIT, macOS-only). Dispatched by skills/test-runner/ to capture native-UI AX-tree snapshots + screenshots on macOS 15+ targets, and exits with deterministic JSON output the orchestrator can parse.
playwright-driver
Use this skill when executing web tests via the canonical playwright npm package (Microsoft, Apache-2.0). Dispatched by skills/test-runner/ to execute web tests against a target, captures token-frugal AX-tree snapshots + screenshots + console output under .orchestrator/metrics/test-runs/ /, and exits with…
quality-gates
Use this skill when referencing canonical quality check commands for typecheck, test, and lint. Defines 4 variants (Baseline, Incremental, Full Gate, Per-File) used by session-start, wave-executor, session-end, and session-reviewer. Reference skill — not invoked directly.
dev-tdd
TDD development with Red-Green-Refactor cycle. Use to implement a feature by writing tests BEFORE the code. Trigger automatically when the user asks for TDD, wants to write tests first, mentions "test first", or asks to implement, add, create, fix, correct code, a new feature, a bugfix, or a functionality.
