In plain words
What is it for?

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

add-registry 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 — 74 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Add a new entry to registry.yaml for the notebook specified in the prompt above.

Instructions

  1. Read the notebook at the specified path to understand its content
  2. Check author exists in authors.yaml:
    • Ask the user for the GitHub username of the notebook author
    • Read authors.yaml and check if that username exists as a key
    • If the author does NOT exist, ask the user for their details and add them to authors.yaml:
      • name: Full display name
      • website: GitHub profile URL or personal website
      • avatar: Use https://github.com/<username>.png as default
  3. Generate the registry entry with these fields:

Required Fields

  • title: Extract from the notebook's first heading or create a concise, descriptive title
  • description: Write a brief 1-2 sentence description summarizing what the notebook teaches
  • path: The notebook path relative to the repository root
  • authors: Use the GitHub username from step 2
  • date: Use today's date in YYYY-MM-DD format
  • categories: Select 1-2 appropriate categories from this list:
    • Agent Patterns
    • Claude Agent SDK
    • Cybersecurity
    • Evals
    • Fine-Tuning
    • Multimodal
    • Integrations
    • Observability
    • RAG & Retrieval
    • Responses
    • Skills
    • Thinking
    • Tools

Style Guidelines

  • Title should be concise but descriptive (see existing entries for examples)
  • Description should be ~15-20 words, focusing on what the user will learn/build
  • Choose categories that best match the notebook's primary focus

Output

  1. If author is new, show the proposed authors.yaml entry for review and add it after approval
  2. Show the user the proposed registry.yaml entry for review
  3. After user approval, use the Edit tool to append the entry to registry.yaml
  4. Maintain alphabetical ordering by path within the file, or append to the end if unclear

Example Entry Formats

authors.yaml (only if new author)

github-username:
  name: Full Name
  website: https://github.com/github-username
  avatar: https://github.com/github-username.png

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.
