GitHub Copilot + VSCode Agent for Marimo Notebooks

Marimo notebooks are now supported natively inside VSCode with an extension. To work on them agentically with the GitHub Copilot Chat Agent, add marimo.agent.md as an agent definition, and select the Marimo agent in the chat.

The agent understands the structure and common patterns of Marimo notebooks. It operates on the Python code directly and you can see the changes reflected instantly.

Default Agent Instructions

• You have useful tools available as MCP or command-line. Use them.
• Unless you are absolutely sure that you have correct and, crucially, up-to-date information in your knowledge, always get information from the web. You can use Tavily for searching and getting information, and you can always use curl to fetch web pages.
• If you are working on something that presents web pages, you should use Playwright to open these pages, take snapshots, and inspect them.
• When working in a git repository, always switch to a new branch, unless explicitly insutrcted not to.
• If the git repo has a corresponding repo on GitHub, use the gh tool for things like looking at issues, opening pull requests, reading review comments, and looking at CI results.

YouTube Transcript SKILL

Get youtube-transcript.zip

Use this skill to fetch the transcript of a YouTube video, with or without timestamps.

Use this skill with Claude (by extracting it to .claude/skills/) or with any other agent using Skillz.

Note: This skill is unlikely to run successfully on the Claude web app, since access to YouTube is blocked. Use it with Claude Code or other local agents.

Markdown Converter Skill

Uses uvx markitdown to convert many document and file types to Markdown.

Great replacement for markitdown-mcp.

Works in Claude (upload markdown-converter.skill), Claude Code (expand the skill zip file into ~/.claude/skills/ or just create a skill directory with SKILL.md) or in any agent using Skillz.

GitHub Pages File-Sharing

If you sometimes find yourself needing to share a file over HTTP, there are not many file-sharing solutions you can use.

This action works by publishing files via GitHub Pages behind an obscure prefix path. It updates the repository README with the URLs, so that you have links to the published files.

You can keep the repository secret, and the files are public but semi-secret, so you can share them without concern that other files will be discovered.

Claude Extended Thinking: The Ultimate Guide

When to use extended thinking across Claude models in the Claude App and Claude Code

What Is Extended Thinking?

Here's my AGENTS.md (also linked from CLAUDE.md as @AGENTS.md) for hacking agentically on MDFlow recipes.

I have this in ~/.mdflow/, and the agents/recipes live in ~/.mdflow/agents/ and added to the path so that they can be invoked as commands.

With this I can use a coding agent like Claude Code or GitHub Copilot in VSCode and say something like:

> create a new agent using copilot that reviews all the code files in this directory as a poem

⌘-Enter to Submit in AI Chats

The cure for premature chat submission - never lose an incomplete prompt again!

Install this user script (using a monkey extension like TamperMonkey or similar) to patch the textbox in common AI chats (currently supports Claude, ChatGPT, Gemini, and Google AI mode) so that instead of using Enter to submit and Shift-Enter for new lines, they use ⌘-Enter to submit and Enter just adds a new line.

Here Be Git

I run dozens of tasks and experiments every day. More often than not, I want the agent to auto-commit to track revisions. But for that, I need a git repo and some instructions. This SKILL sorts that out, and even asks me questions.

Installation

Save SKILL.md to .claude/skills/here-be-git/
