What it does

Add Molab Badge is an agent skill from marimo-team/skills. Add "Open in molab" badge(s) linking to marimo notebooks. Works with READMEs, docs, websites, or any markdown/HTML target.

Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Data & Analytics, covering Jupyter notebooks and Technical documentation. It works with marimo, WebAssembly and GitHub. The repository describes itself as: skills for coding agents related to marimo. The licence is Apache-2.0.

When your agent uses it

Tasks that involve Jupyter notebooks

Example prompts

“Open in molab”

Workflow steps

6 steps, taken from the step headings in SKILL.md.

Session export for molab
Determine the notebook links
Construct the molab URL
Apply the /wasm suffix rules
Format the badge
Insert or replace badges in the target

What it can do on your machine

Read from SKILL.md and the folder at commit 6454470. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
- uvx
- git
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
- marimo.io
- molab.marimo.io
- github.com
- marimo.app
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Add Molab Badge loads about 1.1k tokens when it runs. Until then it costs about 35 tokens; SKILL.md has 489 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~35
When it runs · the whole SKILL.md, loaded when a task matches: ~1.1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description: Add "Open in molab" badge(s) linking to marimo notebooks. Works with READMEs, docs, websites, or any markdown/HTML target.

Add molab badge

Add "Open in molab" badge(s) linking to marimo notebooks. The badge can be added to any target: a GitHub README, documentation site, blog post, webpage, or any other markdown/HTML file.

Instructions

0. Session export for molab

molab previews render much nicer if the github repository has session information around. This can be added via:

bash

uvx marimo export session notebook.py
uvx marimo export session folder/

This executes notebooks and exports their session snapshots, which molab uses to serve pre-rendered notebooks.

Key flags:

--sandbox — run each notebook in an isolated environment using PEP 723 dependencies
--continue-on-error — keep processing other notebooks if one fails
--force-overwrite — overwrite all existing snapshots, even if up-to-date

1. Determine the notebook links

The user may provide notebook links in one of two ways:

User provides links directly. The user pastes URLs to notebooks. Use these as-is — no discovery needed.
Notebook discovery (README target only). If the user asks you to add badges to a repository's README and doesn't specify which notebooks, discover them:
1. Find all marimo notebook files (.py files) in the repository. Use Glob with patterns like **/*.py and then check for the marimo header (import marimo or app = marimo.App) to confirm they are marimo notebooks.
2. If the README already has links to notebooks (e.g., via marimo.app links or existing badges), replace those.
3. Otherwise, ask the user which notebooks should be linked.

2. Construct the molab URL

For each notebook, construct the molab URL using this format:

https://molab.marimo.io/github/{owner}/{repo}/blob/{branch}/{path_to_notebook}

{owner}/{repo}: the GitHub owner and repository name. Determine from the git remote (git remote get-url origin), the user-provided URL, or by asking the user.
{branch}: typically main. Confirm from the repository's default branch.
{path_to_notebook}: the path to the .py notebook file relative to the repository root.

3. Apply the `/wasm` suffix rules

If replacing an existing marimo.app link, append /wasm to the molab URL. This is because marimo.app runs notebooks client-side (WASM), so the molab equivalent needs the /wasm suffix to preserve that behavior.
If adding a new badge (not replacing a marimo.app link), do not append /wasm unless the user explicitly requests it.

4. Format the badge

Use the following markdown badge format:

markdown

[![Open in molab](https://marimo.io/molab-shield.svg)](URL)

Where URL is the constructed molab URL (with or without /wasm per the rules above).

For HTML targets, use:

html

<a href="URL"><img src="https://marimo.io/molab-shield.svg" alt="Open in molab" /></a>

5. Insert or replace badges in the target

When replacing existing badges or links:
- Replace marimo.app URLs with the equivalent molab.marimo.io URLs.
- Replace old shield image URLs (e.g., https://marimo.io/shield.svg or camo-proxied versions) with https://marimo.io/molab-shield.svg.
- Set the alt text to Open in molab.
- Preserve surrounding text and structure.
Edit the target file in place. Do not rewrite unrelated sections.
If the user just wants the badge markdown/HTML (not editing a file), output it directly.

Examples

Replacing a marimo.app badge in a README:

Before:

markdown

[![](https://marimo.io/shield.svg)](https://marimo.app/github.com/owner/repo/blob/main/notebook.py)

After:

markdown

[![Open in molab](https://marimo.io/molab-shield.svg)](https://molab.marimo.io/github/owner/repo/blob/main/notebook.py/wasm)

Note: /wasm is appended because this replaces a marimo.app link.

Adding a new badge from user-provided links:

User says: "Add molab badges for these notebooks: https://github.com/owner/repo/blob/main/demo.py, https://github.com/owner/repo/blob/main/tutorial.py"

Output:

markdown

[![Open in molab](https://marimo.io/molab-shield.svg)](https://molab.marimo.io/github/owner/repo/blob/main/demo.py)
[![Open in molab](https://marimo.io/molab-shield.svg)](https://molab.marimo.io/github/owner/repo/blob/main/tutorial.py)

Note: no /wasm suffix by default for new badges.
