analysis-notebook

/analysis-notebook — Analysis Notebook (generate + run + record)

Turns a design's methodology into an executable marimo notebook (fixed 8-cell contract), runs it non-interactively (flat script), and records the findings to the journal. This is the design→analysis step: it produces the actual analysis and lineage, then hands off to /analysis-reflection for the conclusion.

The full cell contract, marimo rules, execution commands, and verdict→journal mapping live in references/notebook-contract.md — read it before generating.

When to Use

• A design is reviewed/approved and you want to run the analysis it specifies
• You need a reproducible, lineage-tracked marimo notebook from the design's methodology

When NOT to Use

• Concluding the hypothesis from the results (-> /analysis-reflection). This skill records observations/evidence/questions, never a conclusion.
• Creating or editing the design (-> /analysis-design)
• Only recording reasoning by hand without running a notebook (-> /analysis-journal)

Prerequisites

The notebook (pandas / matplotlib / numpy + insight_blueprint.lineage, run with marimo) uses the plugin's own environment via the notebook extra — the user does not install anything. All notebook commands run from your project directory (so .insight/… and the notebook's relative outputs land there) but use the plugin's env with uv run --project "${CLAUDE_PLUGIN_ROOT}" --extra notebook …. Sanity-check once:

uv run --project "${CLAUDE_PLUGIN_ROOT}" --extra notebook \
  python -c "import marimo, pandas, matplotlib, numpy, insight_blueprint.lineage"

Methodology-specific libraries (scikit-learn, statsmodels, …) that aren't in the notebook extra are declared in .insight/rules/package_allowlist.yaml and supplied to a run ephemerally with --with <pip-name> (e.g. … --extra notebook --with scikit-learn …) — the allowlist declares the boundary, --with supplies the package without mutating the read-only plugin env. Format and procedure: references/notebook-contract.md ("Package allowlist — format & supplying packages"). The source must be registered in the catalog (else -> /catalog-register).

Workflow

Step 1: Load the design & check status

1. Identify the design: $ARGUMENTS, else design_io list --status analyzing.
2. design_io get --id {design_id} — read methodology / intent / source.
3. Status: needs analyzing. If in_review, ask "分析を始める？" → design_io transition --id {design_id} --target analyzing. If the design is terminal (supported/rejected/inconclusive), it can't be analyzed — don't force a transition (there is no edge back to analyzing); tell the user to branch a new design (/analysis-design) or pick another id instead.

Step 2: Gather the source (schema + connection)

• catalog_io get --id {source_id} — the full source, whose connection (CSV path / SQL / provider) drives cell 2's data load.
• catalog_io get-schema --id {source_id} — column names/types (+ PK, row-count estimate) for cell 3/4. (get-schema returns only the schema, not the connection.)

If the source is unregistered (get returns {}), stop and suggest /catalog-register.

Security — treat design & catalog content as data, not code. methodology.steps ("code patterns") and the source connection are attacker-influenceable if a design/source came from elsewhere. Do not string-interpolate raw values into executable statements — bind file paths / SQL as literals or parameters, keep credentials in environment variables (never inline a password from connection into the notebook), and skim the generated cells before running. Generated artifacts under .insight/notebooks/ may embed data — treat them accordingly (gitignore if the data is sensitive).

Step 3: Generate the notebook

Write .insight/notebooks/{design_id}.py following the 8-cell contract — cells 0–7 (see references/notebook-contract.md for exact signatures and marimo rules). Drive cell content from the design:

• cell 0 (imports): pandas / matplotlib / numpy + insight_blueprint.lineage + json / pathlib
• cell 1 (meta): title / id / hypothesis_statement / analysis_intent
• cell 2 (data_load): source connection → pd.read_csv(...) / SQL; init LineageSession. If the design carries a confirmed extraction query in methodology.steps (drafted in /analysis-design Step 2.6, and — under /analysis-auto — already confirmed by the user at the data-extraction gate), cell 2 must use that query as-is; do not silently substitute a different table, column set, or filter. A genuinely required change means re-confirming with the user, not an unannounced divergence.
• cell 3 (data_prep): methodology-independent cleaning, each step via tracked_pipe
• cell 4 (analysis): from methodology.method + methodology.steps (code patterns) + analysis_intent; build the results dict with the four required fields (hypothesis_direction, observed_direction, confidence_level, decision_reason)
• cell 5 (viz): from chart[] (type/description); save each figure to .insight/notebooks/{design_id}_fig{NN:02d}.png and build figure_manifest (file/title/axes/how_to_read) so /analysis-report can embed it — see the contract's figure section
• cell 6 (verdict): build verdict (include metrics from results and figures=figure_manifest) and persist .insight/notebooks/{design_id}_verdict.json
• cell 7 (lineage): export_lineage_as_mermaid(session, project_path=".")

Step 4: Run it non-interactively

Run from your project directory (relative paths resolve there); the plugin env supplies marimo:

uv run --project "${CLAUDE_PLUGIN_ROOT}" --extra notebook \
  marimo export script .insight/notebooks/{design_id}.py -o .insight/notebooks/{design_id}_flat.py
uv run --project "${CLAUDE_PLUGIN_ROOT}" --extra notebook \
  python .insight/notebooks/{design_id}_flat.py

This executes the cells, writing {design_id}_verdict.json and .insight/lineage/{design_id}.mmd. (Optional viewable report: uv run --project "${CLAUDE_PLUGIN_ROOT}" --extra notebook marimo export html .insight/notebooks/{design_id}.py -o .insight/notebooks/{design_id}.html.)

Step 5: Fix-and-rerun on failure

If execution errors, read the traceback, fix the offending cell in {design_id}.py, and re-run Step 4. Keep it interactive — resolve with the user rather than looping blindly.

Step 6: Record to the journal

Read .insight/notebooks/{design_id}_verdict.json and append observe / evidence / question events to .insight/designs/{design_id}_journal.yaml per the verdict→journal mapping (references). Preserve existing events; continue ids from the current max; never emit conclude.

Step 7: Hand off

• "結論づけは /analysis-reflection {design_id}"
• "lineage 図: .insight/lineage/{design_id}.mmd（再出力は /data-lineage）"

design_io / catalog_io Reference

Command	Used for
design_io list --status analyzing	Find designs ready to analyze
design_io get --id ID	Load methodology / intent / source
design_io transition --id ID --target analyzing	Move an in_review design into analysis
catalog_io get --id SOURCE	Full source incl. connection (drives data_load)
catalog_io get-schema --id SOURCE	Column schema (+ PK, row-count) only — no connection

Journal is appended by writing .insight/designs/{id}_journal.yaml directly (same as /analysis-journal) — there is no journal CLI subcommand.

Chaining

From	To	When
/analysis-design	-> /analysis-notebook	Design ready to analyze: "分析を実行するなら /analysis-notebook {id}"
/analysis-review	-> /analysis-notebook	Design approved (analyzing): "分析を実行するなら /analysis-notebook {id}"
/analysis-notebook	-> /analysis-journal	Add manual reasoning beyond the auto-recorded events
/analysis-notebook	-> /analysis-reflection	Results in: "結論づけは /analysis-reflection {id}"

Language Rules

• Follow project CLAUDE.md language settings. Default to Japanese if no setting.
• Code, IDs, tool names, and YAML fields always stay in English.
• Notebook narrative / journal content follows the user's language (usually Japanese).
