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

platform-audit 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 6d 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

/platform-audit

Audit a design for platform convention compliance across iOS and Android.

Steps

  1. Platform patterns — Identify which elements follow or depart from native conventions using platform-conventions skill.
  2. Navigation — Review back navigation, tab structure, and gesture zones for each platform using platform-conventions skill.
  3. Controls — Check that components match platform-native equivalents (toggles, pickers, dialogs) using platform-conventions skill.
  4. Typography — Verify system font usage and dynamic type scale compliance for each platform using platform-conventions skill.
  5. Responsive — Confirm layout adapts across screen sizes and orientations using responsive-design skill.
  6. Report — Document findings as platform-mandated patterns, intentional departures, and unintended conflicts.

Output

Platform audit report with compliance findings per platform, categorised by severity: convention violations, gesture conflicts, and recommended changes. Consider following up with /design-screen to redesign non-compliant screens.

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.
