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

c-research 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

What This Skill Does

Uses the summarize CLI to extract key information from URLs, PDFs, YouTube videos, and podcast feeds. Returns a concise summary of the content.

CLI Tool: summarize

Common Commands

# Summarize a web URL
summarize https://example.com/article

# Summarize a PDF (local file or URL)
summarize /path/to/document.pdf
summarize https://example.com/report.pdf

# Summarize a YouTube video
summarize https://www.youtube.com/watch?v=VIDEO_ID

# Summarize a podcast episode
summarize https://podcast-feed-url.com/episode.mp3

# Request a specific output format
summarize --format bullets https://example.com/article
summarize --format paragraph https://example.com/article

Usage Guidelines

  1. Always pass the full URL or absolute file path.
  2. For YouTube, use the full watch?v= URL — short links may not resolve.
  3. If the user asks to "look up", "read", or "check" a link, default to summarizing it.
  4. Present the summary in a clean, readable format — use bullet points for articles, prose for videos/podcasts.

Notes

  • Requires an active internet connection for remote content.
  • Very large PDFs may take longer to process.
  • If summarize is not installed, check the project docs for the install method.

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.
