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 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.

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.

How it starts

The opening of the file, as written. The whole thing — 303 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Summarize

Why? Get the essence of any content in seconds -- no need to read a 30-page doc, sit through a 2-hour transcript, or scroll through 200 Slack messages. Fast, structured, actionable summaries.


Quick Start

"Summarize this article: https://..."
"TL;DR this document" + file path
"Summarize the key points from this meeting transcript"
"What's this PDF about?" + file path

Input Types

Input How to Handle
URL / web page Fetch with WebFetch, then summarize
Local file (.md, .txt, .pdf, .docx) Read with Read tool or appropriate skill
Pasted text Summarize directly
Multiple URLs/files Summarize each, then synthesize
Clipboard content Ask user to paste, or read from clipboard

Workflow

Step 1: Identify Source and Length Target

Detect from user request:

User Says Length Target
"TL;DR" / "one liner" / "gist" Ultra-short: 1-2 sentences
"summarize" / "key points" Standard: 3-7 bullet points
"detailed summary" / "comprehensive" Detailed: structured sections
"compare these" Comparison: side-by-side analysis

Default to Standard if not specified.

Step 2: Fetch Content

URLs:

Use WebFetch to retrieve and extract the page content.

Files:

Use Read tool for text/markdown.
Use s_pdf skill for PDF files.
Use s_docx skill for Word documents.
Use s_xlsx skill for spreadsheets.

Long content (>50K chars): Read in sections, summarize each section, then synthesize into a final summary.

Step 3: Analyze and Summarize

Extract these elements from the content:

Element Always Include? Description
One-line summary Yes What is this about, in one sentence
Key points Yes 3-7 most important takeaways
Context/background If relevant Why this matters, what prompted it
Data/numbers If present Key metrics, stats, figures
Decisions/conclusions If present What was decided or concluded
Action items If present What needs to happen next
Open questions If present Unresolved issues

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.
