What it does
Marimo Development is an agent skill from aiskillstore/marketplace. Expert guidance for creating and working with marimo notebooks - reactive Python notebooks that can be executed as scripts and deployed as apps. Use when the user asks to create marimo notebooks, convert Jupyter notebooks to marimo, build interactive dashboards or data apps with marimo, work with marimo's reactive programming model, debug marimo notebooks, or needs help with marimo-specific features (cells, UI elements, reactivity, SQL integration, deploying apps, etc.).
Its SKILL.md is about 1.5k tokens, which your agent loads only when the skill is triggered. The skill folder holds 91 other files, including reference files (for example `references/NAVIGATION.md`, `references/api/app.md` and `references/api/caching.md`).
It sits in Data & Analytics, covering Jupyter notebooks. It works with marimo, SQL and Python. The repository describes itself as: Security-audited skills for Claude, Codex & Claude Code. One-click install, quality verified.
When your agent uses it
- The user asks to create marimo notebooks
- Convert Jupyter notebooks to marimo
- Build interactive dashboards
- Data apps with marimo
Example prompts
- “/marimo-development”
Requirements
- Python 3
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Start with fundamentals: Read references/core-concepts.md - contains marimo's cell structure, reactivity model, UI elements, and essential…
- Use recipes for common tasks: Check references/recipes.md for code snippets
- Refer to API docs: Navigate references/api/ for specific function details
- Troubleshoot issues: See references/faq.md and references/troubleshooting.md
What it can do on your machine
Read from SKILL.md and the folder at commit 4ac52da. 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
No scripts in the folder and no shell commands in SKILL.md (its code samples are python).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
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
Marimo Development loads about 1.5k tokens when it runs, and up to ~47k if it reads all its reference files. Until then it costs about 124 tokens; SKILL.md has 423 words of instructions outside code blocks.
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.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 423 words (~1,517 tokens).
“Create reactive Python notebooks with marimo's interactive programming environment.”
