Brainstorm a Research Approach or Methodological Decision

Pipeline mode: This command operates fully autonomously. All decisions are made automatically.

Brainstorming helps answer WHAT approach to take through structured analysis. It precedes /workflows:plan, which answers HOW to implement it.

Process knowledge: See references/brainstorming-techniques.md for detailed question techniques, approach exploration patterns, and parsimony principles.

Research Question

<feature_description> #$ARGUMENTS </feature_description>

If the research question above is empty: Infer the question from recent context — open files, recent conversation, or the project's estimation code. If no context is available, state "No research question provided" and stop.

Execution Flow

Phase 0: Assess Scope

Evaluate whether brainstorming is needed based on the research question.

Clear requirements indicators:

• Specific estimator or method already chosen
• Referenced existing implementation to follow
• Described exact identification strategy
• Constrained, well-defined methodological scope

If requirements are already clear: Skip brainstorming and note: "Requirements are detailed enough to proceed directly to planning. Run /workflows:plan to continue." Then stop.

If requirements need exploration: Proceed to Phase 1.

Phase 1: Understand the Problem

1.1 Codebase and Literature Research

Run a targeted scan to understand existing patterns and related methods:

• Task methods-explorer("Understand existing methodological patterns and approaches related to: <research_question>")

Focus on: existing estimation code, identification strategies used in this project, methodology documented in papers or notes.

1.2 Problem Decomposition

Analyze the research question systematically without user interaction:

1. Core question: What is the fundamental methodological decision being made?
2. Constraints: What data limitations, computational budgets, or identification requirements constrain the choice?
3. Prior art: What has this project already done that's similar? What methods are established in the literature?
4. Success criteria: What would a good solution look like? (e.g., consistent estimation, reasonable computational cost, testable identification)

Document findings from the research agent and decomposition. If the question is ambiguous, pick the most natural interpretation given the project context and note the assumption.

Phase 2: Compare Approaches

Propose 2-3 concrete methodological approaches based on research and analysis.

For each approach, provide:

Criterion	Approach A	Approach B	Approach C
Description	2-3 sentence summary	2-3 sentence summary	2-3 sentence summary
Theoretical properties	Consistency, efficiency, robustness to misspecification	...	...
Identification requirements	What assumptions are needed? How testable are they?	...	...
Computational cost	Estimation time, convergence difficulty, parallelizability	...	...
Data requirements	Sample size needs, variable availability, panel structure	...	...
Software availability	Packages (Python/R/Julia), maturity, documentation	...	...
Monte Carlo evidence	Finite-sample performance from methodology literature	...	...

Recommendation: Select the simplest approach that satisfies the identification requirements. Apply parsimony — prefer well-understood methods with established software implementations over novel approaches unless the research question specifically demands novelty.

Document why the recommended approach was chosen and what conditions would favor the alternatives.

Phase 3: Capture the Analysis

Entry condition: Phase 2 comparison table is complete with all criteria filled for all approaches. Exit condition: Document written to docs/brainstorms/ with all required YAML frontmatter fields.

Artifact Storage

Write the brainstorm output to docs/brainstorms/<topic>-requirements.md with YAML frontmatter:

---
status: active
date: YYYY-MM-DD
topic: <descriptive topic>
---

If docs/brainstorms/ contains a recent document matching this topic, ask the user: "Found existing brainstorm on this topic. Continue from it, or start fresh?"

Write a brainstorm document to docs/brainstorms/YYYY-MM-DD-<topic>-brainstorm.md.

Ensure docs/brainstorms/ directory exists before writing.

Document structure:

---
title: [Brainstorm Topic]
date: YYYY-MM-DD
status: complete
recommended-approach: [Name of recommended approach]
---

Phase 4: Handoff

Pipeline mode (invoked from /lfg or /slfg):

• Skip the summary display entirely
• Immediately invoke /workflows:plan with the brainstorm document path as context
• Do not pause or present options

Standalone mode (invoked directly by the user):

Display the closing summary:

Brainstorm complete!

Document: docs/brainstorms/YYYY-MM-DD-<topic>-brainstorm.md

Recommended approach: [Approach Name]
Key rationale: [One-line summary]

Alternatives documented:
- [Alternative 1]: [When to prefer]
- [Alternative 2]: [When to prefer]

Then present these options:

What would you like to do next?

1. Proceed to planning (Recommended) — Run /workflows:plan now with this brainstorm
2. Refine the brainstorm — Revisit the Phase 2 comparison with updated criteria
3. End session — The brainstorm document is saved; pick up later with /workflows:plan

Wait for the user to choose:

• Option 1: Invoke /workflows:plan with the brainstorm document path as context.
• Option 2: Return to Phase 2, keeping the existing approaches but allowing revised criteria, new approaches, or a different recommendation.
• Option 3: Stop. The document is already saved.

Important Guidelines

• Stay focused on WHAT approach, not HOW to implement — implementation details belong in the plan
• Apply parsimony — prefer simpler, well-understood methods unless complexity is justified
• Be specific about tradeoffs — "more efficient but requires stronger assumptions" not "has pros and cons"
• Ground in real methods — cite actual estimators (2SLS, GMM, MPEC), packages (statsmodels, fixest, PyBLP), and papers
• Keep outputs concise — 200-300 words per section max

Routes To

• /workflows:plan — proceed with the chosen approach
• literature-scout agent — for deeper literature search on a specific method
• methods-explorer agent — for deep dives into estimator properties and software implementations

NEVER CODE! Just explore and document methodological decisions.
