Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

finesse-skill AGENTS.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 13d 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 — 161 lines — stays where its author put it; the contents beside it link to each section on GitHub.

finesse — Agent Instructions

For OpenAI Codex and other agent runtimes that read AGENTS.md. The full skill is at skills/finesse-ui/SKILL.md. Deep reference material lives in skills/finesse-ui/references/. Load what you need per phase — do not inline everything at once.


Apple design language

For Apple / 苹果风 requests, read skills/finesse-ui/references/apple-design.md before choosing the substrate. Keep the register and add design-language=apple plus apple-mode=editorial|app|spatial. The scoped aesthetic overrides there supersede conflicting defaults in this file. Editorial recipes and seven portable interactive studies are indexed in skills/finesse-ui/references/apple-patterns.md. Reuse interaction-motion.md for gestures; app and spatial do not automatically mean Bento or glass everywhere.

What finesse does

finesse builds interfaces routed by register:

  • brand — landing pages, brand sites, launches, portfolios, hero pages. Design IS the product. Optimize for spectacle + soul + first impression. Uses a real visual engine (Three.js / Canvas / GLSL / GSAP).
  • product — dashboards, admin panels, analytics, data tables, app shells, settings. Design SERVES the product. Optimize for clarity + density + usability.
  • commerce — PDP, PLP, cart, checkout. A hybrid: route to brand or product by what the specific page is doing.
  • h5 — pages that only ever live on a phone: H5 / 移动端页面 / 活动页 / mini-program screens / app prototypes / mobile PDPs. A container register — it fixes the phone frame, safe areas, thumb zone and native furniture, then wraps one of the three above for content. A mobile PDP is h5 + commerce.

All share the same premium substrate and anti-slop blacklist. None is allowed to look cheap.


Commands (targeted iteration)

A full build runs the whole workflow below. For iterating on an existing page, route the request through one verb instead of rebuilding — Codex has no slash commands, so map the user's intent to the verb and load only that reference.

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.
