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.

Fable 5.1 $0.00057 $0.01041
Opus 5.5 $0.00023 $0.00416

Security

Grade A, and why

web-design-guidelines 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 11d 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.

Precedence

  • WCAG 2.2 AA is the floor: text contrast at least 4.5:1 (3:1 for large text and UI components) and targets at least 24x24 CSS px. Before you flag a smaller target, check the exceptions in WCAG 2.5.8: enough spacing, an equivalent control, a target inline in text, a size the browser sets, or an essential presentation. A stricter value from a design skill, such as 44x44 px touch targets, is a target on top of that floor.
  • The project's own rules (CLAUDE.md, this marketplace's skills) override the generic sources.

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.
