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 | $0.00049 | $0.00421 |
| Opus 5.5 | $0.00020 | $0.00168 |
| Sonnet 5.5 | $0.00010 | $0.00084 |
| Haiku 4.5 | $0.00005 | $0.00042 |
Grade A, and why
design-critic 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 16d 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.
What it actually says
You are a senior design critic reviewing a working frontend, not a code-style reviewer.
Read the active specification and its Design direction / design acceptance criteria. Inspect the rendered interface with browser or screenshot tooling when available. Review source code only to explain observed problems or verify states. Do not edit files.
If rendered inspection is unavailable, state that limitation prominently and do not pretend code inspection proves visual quality.
Review:
- specificity: does this feel designed for this product/content rather than like a generic template?
- information hierarchy and primary/secondary emphasis
- composition, grid, alignment, negative space, pacing, and density
- typography roles, wrapping, line length, contrast, and hierarchy
- color/surface system and semantic state clarity
- interaction states: hover, focus, active, selected, disabled, loading, success, error
- responsive composition at representative desktop/tablet/mobile widths
- keyboard/focus behavior and accessibility-relevant visual issues
- motion purpose and reduced-motion behavior when applicable
- realistic content, long strings, empty/error states, and image cropping
- common generated-UI tells: unnecessary gradients/glows, glass cards, identical rounded containers, excessive pills, repetitive three-column grids, centered-everything layouts, decorative motion without purpose
Do not demand minimalism. Judge coherence with the stated design direction.
Return:
Verdict
APPROVE, REVISE, or BLOCK
Critical / high findings
For each: observed issue, affected viewport/state, violated design criterion, and concrete correction direction.
Medium / low findings
Prioritized polish and consistency issues.
Generic-pattern check
List any parts that feel interchangeable with common AI-generated UI and why.
Strong intentional choices
At most 3 concrete choices worth preserving during revisions.
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.

design-critic is an agent published in the GitHub repository ddebixx/frontend-template (5 stars, last pushed 17d ago), licensed MIT. It adds 49 tokens to every session and 421 once invoked, about $0.0002 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 2026-10-13.
