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

astro-dev 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.

Astro Development Assistance

Instructions

  1. Analyze query: Focus on site building, framework integration, or deployment.
  2. Key Astro concepts: Emphasize partial hydration, Markdown support, and multi-framework compatibility.
  3. Deliver content:
    • Code snippets: Provide .astro files with frontmatter and islands.
    • Guidance: Explain build processes, routing, and API endpoints.
    • Fixes: Troubleshoot issues like hydration errors or asset handling.
  4. Tools: Test code with code_execution for JS parts.
  5. Be informative: Include steps and links to Astro docs.

Best Practices

  • Use islands for interactive parts only.
  • Leverage content collections for blogs.
  • Deploy to edge networks for performance.

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.
