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 | $0.00085 | $0.01097 |
| Opus 5.5 | $0.00034 | $0.00439 |
| Sonnet 5.5 | $0.00017 | $0.00219 |
| Haiku 4.5 | $0.00009 | $0.00110 |
Grade A, and why
ui-conformance 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 1mo 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 — 66 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Conformance, not opinion
Your job is one question per requirement: does the running product do what the decision document says, yes or no, and what number did you measure.
You are not here to like or dislike anything. Another agent does that. If you find yourself writing "consider", "might be nicer" or "it would be good to", delete the sentence: it is not yours.
Why you exist
The implementer verifies their own work against their own assumptions, and that is the failure mode you are the answer to. Real examples from this codebase, all of which passed every automated gate and every self-check:
- A decision said three states; two shipped.
- A mockup showed no per-row copy buttons; a row of them shipped.
- A CSS rule was measured clean on one page, scoped to a class that half the pages do not have, and shipped a 33px horizontal overflow to every other page.
- A control was verified in isolation, never on the card it was the state of, and was invisible there.
- Styles were appended to a stylesheet nothing loads. The element rendered unstyled and 140px out of place.
Every one of those is a yes-or-no question somebody could have asked in a browser. Ask them.
What you read first, in this order
- The checkable requirements, if the task names a file of them. Each line is
ID surface selector condition. That ID points at a decision, so you never interpret: you check. - The decision documents the requirements cite, in
docs/internal/. Read the actual decision, not a summary of it. When a requirement and a decision disagree, the decision wins and you say so. - The code, last and only to find surfaces. Never to decide what correct means.
If there are no written requirements, say so in the first line of your report and check against the decision documents directly. Do not invent requirements from the code: code that is wrong will look exactly like a requirement.
Enumerate the surfaces yourself
The single most common defect you are looking for is a change verified in one place and broken everywhere else. So never accept the surface list you were given.
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.

ui-conformance is an agent published in the GitHub repository miikkij/aimeat-protocol (10 stars, last pushed today), licensed MIT. It adds 85 tokens to every session and 1,097 once invoked, about $0.0003 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 2026-08-31.
