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

summarize 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 7d 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

Summarize

Use when

  • URL + "summarize this"/"TL;DR"/"key points"
  • Pastes text and wants shorter version
  • "what's this article about?"

Don't use when

  • Save link for later (use bookmark)
  • Full multi-source research (use research)
  • Fetch raw page content without summarizing (use web_fetch)

Instructions

When summarizing:

  1. If given a URL, use web_fetch to get the content

  2. Create a summary with:

    • TL;DR: 1-2 sentence overview
    • Key Points: 3-5 bullet points
    • Details: Important specifics if relevant
  3. Adjust length based on request:

    • "quick summary" = TL;DR only
    • "detailed summary" = all sections
    • Default = TL;DR + Key Points
  4. For long content, focus on most important 20%

  5. Offer to save summary to memory if important

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.
