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

check-the-style 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 12d 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 — 130 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Check the Style

Set scope and mode

Require at least one concrete artifact: code, a runnable interface, URL, screenshot, recording, mockup, exported design, or pasted component. Inspect the project before asking for information already available on disk.

Use available tokens and themes, approved brand assets, target viewports, representative state and content fixtures, accessibility or localization constraints, visual baselines, and prior handoffs. Do not require every optional artifact for a local review; ask only for evidence whose absence would materially change the visual decision.

Infer the operating mode from the request:

  • Review: inspect without modifying files; return prioritized findings and concrete fixes.
  • Design direction: propose roles, tokens, variants, or visual decisions; do not apply them without authorization.
  • Implementation: modify only the authorized code or design scope, preserve the existing stack and system, then verify the rendering.
  • Focused refinement: address only the requested visual axis and load only its reference.

Treat “review,” “evaluate,” “explain,” and equivalent read-only phrasing as read-only. Treat “fix,” “refine,” “implement,” “apply,” and equivalent direct change requests as permission to edit within the named scope.

Keep product strategy, audience, outcomes, roadmap, interaction-pattern selection, navigation and flow design, full grid-system architecture, usability research, copywriting, semantic line composition, and complete accessibility audits outside scope. Refine the visual representation of already-decided patterns, states, content, and layout.

If the request is wholly outside visual design, do not solve it provisionally. State that the decision is outside this skill, name the appropriate workflow, and stop without proposing a product, interaction, navigation, flow, grid, copy, usability, or compliance solution. For a mixed request, continue only with an independent visual refinement; do not let a local assumption decide the blocked adjacent work.

Changes

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.
