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 | $0.00000 | $0.00562 |
| Opus 5 | $0.00000 | $0.00281 |
| Sonnet 5 | $0.00000 | $0.00112 |
| Haiku 4.5 | $0.00000 | $0.00056 |
Grade A, and why
perf 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 today.
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.
The source is not reproduced here
A licence we could not identify
The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.
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.

perf is a command published in the GitHub repository TidyFactor/Cinematic (3 stars, last pushed 2d ago), with no licence file. It costs nothing until one of its globs matches a file; then it loads 562 tokens. 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 2026-09-07.
Other commands, from other repositories
theme-swap
Recolour an extracted site's design around a new brand primary. OKLCH hue rotation preserves perceptual lightness — neutrals, type, spacing, and motion stay untouched. Side-by-side HTML preview + recoloured tokens (DTCG, Tailwind, shadcn, Figma).
color-palette
Run the full colour workflow — tonal scales, semantic mapping, contrast checks, dark mode, and chart colours — and output a documented palette.
design-screen
Design a complete screen layout from a description or requirements.
responsive-audit
Audit a design's responsive behaviour across breakpoints — layout, touch targets, and content reflow.
ux-motion
Animation and motion rubric. Checks timing, easing, meaning, reduced-motion compliance, and performance for every animation on a surface. Triggers on "motion check", "are the animations good", or "fix the motion". Use when auditing motion or animations, checking durations / easing / reduced-motion / performance, is…
ux-system
Propose a complete starter design system for a project that doesn't have one. Triggers on "we don't have a design system", "build us a system", "propose tokens", "what should our theme be". Use when proposing a starter design system, generating tokens / foundations / components from a brand brief, the project has no…
