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

theme-builder 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 yesterday.

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

/theme-builder: Build or Improve Theme

Build a complete light + dark theme from a brand color, or improve an existing theme.

Flow

  1. Determine brand color and style direction
  2. Generate palette with uiux_generate_palette:
    • Brand: primary, primary-foreground
    • Neutral: 11-step scale from lightest to darkest
    • Semantic: success, error, warning, info (each with base, light, dark)
    • Surfaces: background, surface, elevated, overlay
    • Text: primary, secondary, muted, inverse
    • Borders: default, strong, muted
    • Interactive: focus ring, selection, hover overlay
  3. Generate dark mode variant (proper dark mode, not inverted)
  4. Output in project-appropriate format (CSS vars, Tailwind, shadcn theme)

Output

Complete theme configuration ready to paste into the project.

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.
