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 | $0.02348 | $0.02348 |
| Opus 5.5 | $0.00939 | $0.00939 |
| Sonnet 5.5 | $0.00470 | $0.00470 |
| Haiku 4.5 | $0.00235 | $0.00235 |
Grade A, and why
ui-kit CLAUDE.md 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.

UI Kit — Claude Code Project Guide
Project Overview
@annondeveloper/ui-kit — A zero-dependency React component library with 147 components across 3 weight tiers (Lite/Standard/Premium), physics-based animations, OKLCH color system, and Aurora Fluid design identity.
Repository: https://github.com/annondeveloper/ui-kit
Current: v2.8.1 on main branch
Legacy: v0.4.1 on v1 branch (archived)
Development Philosophy
Quality over speed. Always. Take as many turns, tokens, and time as needed to implement things properly. Never rush. This is a revolutionary library — every component must be built with care:
- Full TDD: write failing tests first, verify they fail, then implement
- Run spec compliance review AND code quality review after each task
- One task at a time — don't combine phases to save time
- Verify thoroughly: tests, build, typecheck, visual inspection
- Fix issues before moving on — never leave known problems for later
- Write comprehensive tests including edge cases, not just happy-path
- Build demo pages and Storybook stories alongside components, not deferred
- Visually inspect every component in browser after implementation
Key Architecture Decisions (v2)
- Zero external dependencies — only peer deps are
react^19 andreact-dom^19 - Embedded scoped CSS —
useStyles()hook auto-injects CSS viaadoptedStyleSheets - Dual-mode CSS — auto-inject for React users, standalone
.cssfiles for others - OKLCH color system — perceptually uniform, with relative color syntax for theme generation
- Aurora Fluid design — deep atmospheric surfaces, ambient glows, ethereal color washes
- Physics-based animations — real spring solver (differential equation), not approximations
- Motion intensity —
--motionCSS property (0=none, 1=subtle, 2=expressive, 3=cinematic) - Progressive enhancement — modern CSS features with
@supportsfallbacks - Built-in form engine —
createForm(),useForm(), validators, zero external deps - Container-first responsive — components adapt to container, not viewport
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-kit CLAUDE.md is an instructions file published in the GitHub repository annondeveloper/ui-kit (0 stars, last pushed 4mo ago), licensed MIT. It adds 2,348 tokens to every session, about $0.0094 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.
