What it does
Anywidget Generator is an agent skill from ericmjl/llamabot. Generate anywidget components for marimo notebooks.
Its SKILL.md is about 960 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. It works with marimo and JavaScript. The repository describes itself as: Pythonic class-based interface to LLMs.
When your agent uses it
- Tasks that involve Jupyter notebooks
Example prompts
- “/anywidget-generator”
Requirements
- Python 3
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Use vanilla JavaScript in _esm
- Include _css styling
- Wrap the widget for display
- Keep examples minimal
- External file paths: When using pathlib for external _esm/_css files, keep paths relative to the project directory, consider using…
What it can do on your machine
Read from SKILL.md and the folder at commit 30d24ae. 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.
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
Anywidget Generator loads about 957 tokens when it runs. Until then it costs about 18 tokens; SKILL.md has 470 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: warnings
The automated check found patterns that need a careful read before installing.

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 470 words (~957 tokens).
