Marimo Notebook Inspector
Inspect marimo notebook execution results by reading HTML snapshots stored in the __marimo__ directory.
Purpose
Marimo automatically saves HTML snapshots during editing sessions. This skill reads those snapshots to verify:
- Cell execution outputs
- Error messages and tracebacks
- Visualization renders
- UI element states
Snapshot Location
HTML snapshots are stored in:
__marimo__/directory (relative to notebook).marimo/directory (alternative location)
Workflow
- Locate the
__marimo__or.marimo/directory using Glob - List available HTML snapshots
- Read the HTML file with the Read tool
- Parse and analyze:
- Cell outputs (text, tables, plots)
- Error states and messages
- Console output
- Report findings to user
Usage Pattern
# Find snapshots
Glob: **/__marimo__/*.html
# Read snapshot
Read: __marimo__/notebook_name.html
Analysis Focus
When inspecting HTML snapshots:
- Look for
<div class="output">sections for cell outputs - Check for error indicators and stack traces
- Identify visualization elements (plots, charts)
- Note any warning or info messages
