Marimo Eda Prototype

Marimo EDA Prototype

Responsible for prototype-first marimo notebooks, not turning notebooks into interactive products.

USE FOR

• Create or modify marimo notebooks for EDA / prototype analysis
• Optimize notebook cell cohesion, interaction density, and module boundaries
• Determine whether a piece of notebook logic should be extracted to a helper / module

DO NOT USE FOR

• Full frontend applications or long-term UI products
• General Python script development
• Pure API queries without notebook structure decisions

Execution Skeleton

1. First confirm the notebook's primary task is still analysis, not UI orchestration.
2. Follow [workflow](references/workflow.md): write the static analysis version first, then decide whether to add minimal interaction.
3. Use [boundary](references/boundary.md) and [design-patterns](references/design-patterns.md) to assess cell cohesion, graph hygiene, and extraction signals.
4. For technical checks, prefer running uvx marimo check; [eval-fixtures](references/eval-fixtures.md) serves as sample notebooks for evaluation.

Reference Map

• [boundary](references/boundary.md): boundaries, guardrails, decision table, examples
• [workflow](references/workflow.md): default workflow, guardrails, pre-completion checklist
• [design-patterns](references/design-patterns.md): high-value patterns and anti-patterns
• [eval-fixtures](references/eval-fixtures.md): sample notebooks and evaluation materials
• [trigger-cases](evals/trigger-cases.md): minimal trigger examples
• [execution-cases](evals/execution-cases.md): key execution scenarios
• [optimization-notes](reports/optimization-notes.md): current round refactoring decisions

Output Contract

• Default output is an analysis-first, interaction-restrained, clearly structured marimo notebook
• If the notebook is evolving into an app, explicitly recommend extracting modules or transitioning to product code
