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
code
# 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
