Brainstorm

Overview

Use this skill to convert rough ideas into clear, reviewable design outputs through structured dialogue.

The goal is to:

1. Clarify requirements and constraints
2. Explore alternatives with trade-offs
3. Produce a concrete, validated design brief in artifacts or a handoff to planning

Workflow

Step 1: Gather Project Context

Load only the project context relevant to the current idea:

• If docs/SUMMARY.md exists, read it first.
• Load only task-relevant detail docs.
• Prioritize Code Standard docs for implementation conventions.
• If docs conflict with code or user intent, use the available interactive input/question tool before broad changes.

Also check key implementation files relevant to the idea and note constraints from existing architecture, dependencies, and conventions.

Keep this pass focused. Only gather what is needed for the current idea.

Step 2: Clarify Requirements

Ask targeted questions sequentially to remove ambiguity with interactive input/question tool:

• Focus on:
  • Objective and user value
  • Scope boundaries
  • Constraints (technical, UX, performance, timeline)
  • Success criteria
  • Non-goals

Do not jump to implementation details too early.

Step 3: Explore Approaches

Propose 2-5 viable approaches.

For each approach, include:

• Short summary
• Pros
• Cons / risks
• Complexity estimate
• Recommended use conditions

Lead with your recommended option and explain why it best fits the project context and constraints.

After presenting all approaches, use interactive input/question tool to let the user pick their preferred approach. List the summary options. Example:

• Approach A, short summary
• Approach B, short summary
• Approach C, short summary
• Other (please specify)

with the tag added for the recommended approach to guide the user.

Step 4: Present the Design Incrementally

After user selection, present the design incrementally with sections:

• 1. Foundation - Problem framing, goals, and proposed architecture/flow.
• 2. Technical Details - Data model, interfaces, error handling, edge cases and risks.
• 3. Delivery - Testing/verification strategy and rollout considerations (if applicable).

After presenting, use input/question tool immediately to ask whether to:

1. Proceed to the next step
2. Adjust the design (require typing)

Step 5: Close the Loop

After you and the user have worked through requirements and the design is validated, determine the next actions.

Use input/question tool to present the user with three high-level next actions:

• "Write plan immediately" - skip the artifact step and move straight to a write-plan handoff with visualization.
• "Write artifacts" - continue by authoring the brainstorm documents described in Step 6.
• "Implement immediately" - if the design is clear and low-risk, the user may choose to skip both artifacts and planning and move straight to implementation.
• "End session" - stop; the conversation has produced enough insight for now.

Step 6 (optional): Write Brainstorm Artifacts

Only perform this step after the user has explicitly chosen "Write artifacts" during Step 5.

Persist results to the standardized location:

• Directory: docs/.brainstorms/YYMMDD-HHmm-<topic-slug>/
• Main file (required): docs/.brainstorms/YYMMDD-HHmm-<topic-slug>/SUMMARY.md
• Optional supporting files:
  • docs/.brainstorms/YYMMDD-HHmm-<topic-slug>/section-01-<slug>.md
  • docs/.brainstorms/YYMMDD-HHmm-<topic-slug>/section-02-<slug>.md
  • etc.

SUMMARY.md format: strictly follow the template inside references/summary-template.md.

Once the draft artifacts exist, use input/question tool again to validate them with options:

• "Write plan with current artifacts, context"
• "End session - artifacts are sufficient for now"
• "Need changes" (free-form text) - collect the feedback, revise the artifacts, and re-ask.

Rules

• Do not write production code or make implementation changes in this skill in the brainstorm session.
• Keep interaction lightweight and iterative; every step should be run in the same session.
• Prefer clarity over completeness when uncertain; ask a follow-up question.
• Align all recommendations with project documentation and standards.
• Keep assumptions explicit; do not guess silently.
• Think before coding: Surface assumptions explicitly. If multiple interpretations exist, present them — don't pick silently. If a simpler approach exists, say so and push back when warranted.
• Write all artifacts in language same with the current session.
