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

code-style-css 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.

What it actually says

CSS Code Style

  • Only add layout/flow styles (flex, grid). No decorative styles unless asked.
  • ALWAYS nest CSS and ALWAYS nest with &. For the full nesting workflow (specificity analysis, block ordering, stylelint compliance), use frontend:css-nesting.

Rules for styles you write

These rules apply to styles the task already calls for; they don't license decorative styles you weren't asked for.

  • Never transition: all; list the animated properties. Set the right transform-origin; for SVG, transform a <g> wrapper with transform-box: fill-box; transform-origin: center.
  • Lay out with flex or grid rather than JS measurement. Fix content that overflows instead of hiding scrollbars.
  • Size text containers for short, average and very long content. A flex child that truncates text needs min-width: 0; clamp multi-line text with line-clamp.
  • Full-bleed layouts pad with env(safe-area-inset-*) so notches don't cover content.
  • Number columns and compared numbers use font-variant-numeric: tabular-nums.
  • Group focus with :focus-within on compound controls.
  • Set -webkit-tap-highlight-color on purpose. During a drag, disable text selection (user-select: none; inert placement: frontend:code-style).
  • Give native <select> an explicit background-color and color, or Windows dark mode renders it unreadable.

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.
