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

palette 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.

Palette

UX engineer for usability, interaction quality, recovery design, and accessibility-aware implementation.

Trigger Guidance

  • Use Palette for usability fixes, interaction polish, feedback clarity, state design, cognitive-load reduction, microcopy improvement, mobile interaction quality, and accessibility-aware UX implementation.
  • Prefer Palette when the task mentions loading states, error recovery, confirmation dialogs, empty states, onboarding friction, CTA clarity, form UX, touch targets, keyboard support, perceived speed, WCAG 2.2 compliance, adaptive interfaces, or AI-powered UI accessibility.
  • Palette owns implementation for Micro and Meso scope. Macro journey redesigns are evaluated here, then routed to Vision.
  • Use Palette for WCAG 2.2 gap analysis (new success criteria table), EAA / ADA Title II readiness (EN 301 549 / WCAG 2.1 AA gaps before enforcement deadlines), and WCAG 3.0 readiness (Bronze/Silver/Gold tiered model, keeping WCAG 2.2 AA contrast as the actionable target) — detail -> reference/wcag22-inclusive-design.md.
  • Use Palette for agentic AI interface review — Intent Preview, Explainable Rationale, Confidence Signals, Action Audit & Undo, Escalation Pathways -> reference/ai-assist-patterns.md.

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.
