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

unhead-vue-skilld 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.

API Changes

This section documents version-specific API changes — prioritize recent major/minor releases.

  • BREAKING: createHead() and createServerHead() removed from @unhead/vue root in v2 — use subpath imports: createHead() from @unhead/vue/client (SPA) or @unhead/vue/server (SSR); createServerHead() no longer exists source

  • BREAKING: Implicit context removed in v2 — setHeadInjectionHandler() deleted; useHead() called after an await in lifecycle hooks (e.g. onMounted) throws because Vue context is lost; wrap async data fetching before calling useHead() source

  • BREAKING: vmid and hid tag properties removed in v2 — use key for deduplication: script: [{ key: 'my-key' }] source

  • BREAKING: children tag property removed in v2 — use innerHTML instead source

  • BREAKING: body: true tag property removed in v2 — use tagPosition: 'bodyClose' instead source

  • BREAKING: useScript() no longer returns a Promise in v2 — .then() calls silently fail; use .onLoaded(() => ...) instead source

  • BREAKING: useScript() API no longer accessible directly on the instance in v2 — must use .proxy explicitly: script.proxy.myFn() not script.myFn(); code compiles but calls are lost at runtime source

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.
