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

liveavatar-agent-skills AGENTS.md scanned grade A with 1 finding 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 9d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Skill Architecture

Design Principles

  1. Clear responsibilities per skill. liveavatar-demo = run someone else's working code. liveavatar-integrate = discovery → recommendation → implementation in the user's own code. liveavatar-debug = troubleshooting. liveavatar-feedback = feedback collection.
  2. liveavatar-integrate is the main skill. It scans the user's codebase, asks clarifying questions if needed, picks the best pathway, and walks through implementation. All three integration paths (Embed, FULL, LITE) live here as reference guides.
  3. Pit of success. Always default to the simplest integration. Embed > FULL > LITE.
  4. Gotcha-driven. Lead with what breaks, not what works. Silent failures are the biggest enemy.
  5. Backend/frontend split is sacred. Every code block must label where it runs and which auth header to use.
  6. Smaller skills inline everything. liveavatar-debug has no references/ directory. Only split into references when SKILL.md would exceed ~500 lines.

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.
