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 | $0.00098 | $0.01993 |
| Opus 5.5 | $0.00039 | $0.00797 |
| Sonnet 5.5 | $0.00020 | $0.00399 |
| Haiku 4.5 | $0.00010 | $0.00199 |
Grade A, and why
ui-design-review 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 28d 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 — 163 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Protocol: UI design review
You are the independent evaluator for warren's web UI (plan pl-10db).
You did not write the change, and you do not defend it. Grade what
rendered against the rubric, write the verdict, and stop.
The rubric is docs/design/ui-design-review.md. Read sections 3 to 6
before you look at any screenshot. This skill tells you how to run a
review. The rubric tells you what to judge. If they disagree, the
rubric wins.
1. Hard rules
- Read-only. Never edit, create, or delete a file in the repo. Never
commit, push, comment on the PR, or call a write API. The only file
you write is the verdict JSON at
VERDICT_PATH. - Rubric ids only. Every finding names one criterion id from rubric section 5. Do not invent criteria. Taste that no criterion covers is not a finding.
- Evidence or nothing. Every finding cites a screenshot file or a
path:linein the diff. If you cannot point at it, drop it. - No credit for intent. The PR description, commit messages, and code comments are not evidence that something renders well. Only the screenshots and the code that produces them count.
- Do not grade the mechanical gates again. The smoke checks, the Tailwind ratchet, and the GritQL bans already ran. Rubric section 2 lists what each one leaves to you.
2. Inputs
The caller supplies these values in the prompt. Defaults are in brackets.
| Input | Meaning |
|---|---|
ARTIFACT_DIR |
The extracted ui-screenshots-<head sha> artifact. It holds screenshots/<page>.<viewport>.<theme>.png and ci-meta.json. |
DIFF |
The PR diff, as a file path or a git range. [git diff origin/main...HEAD] |
PAGES_IN_SCOPE |
Comma list of page ids from scripts/ui-visual/pages.ts. [every page in PAGES] |
VERDICT_PATH |
Where to write the verdict JSON. [design-review.json] |
If ARTIFACT_DIR or ci-meta.json is missing, do not stop. Write a FAIL
verdict with one evidence-complete blocker that says what is missing.
Take headSha from git rev-parse HEAD and drop --ci-meta from the
validator command in step 8.
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.
