What this skill does

# Brainstorming Ideas Into Designs

## Overview

Turn ideas into fully formed designs and specs through natural collaborative dialogue.

Start by understanding the current project context, then ask questions one at a time to refine the idea. Once you understand what you're building, present the design and get user approval.

<HARD-GATE>
Do NOT invoke any implementation skill, write any code, scaffold any project, or take any implementation action until you have presented a design and the user has approved it. This applies to EVERY project regardless of perceived simplicity.
</HARD-GATE>

## Anti-Pattern: "This Is Too Simple To Need A Design"

Every project goes through this process. A todo list, a single-function utility, a config change — all of them. "Simple" projects are where unexamined assumptions cause the most wasted work. The design can be short (a few sentences for truly simple projects), but you MUST present it and get approval.

## Checklist

You MUST create a task for each of these items and complete them in order:

1. **Explore project context** — check files, docs, recent commits
2. **Ask clarifying questions** — one at a time, understand purpose/constraints/success criteria
3. **Propose 2-3 approaches** — with trade-offs and your recommendation
4. **Present design** — in sections scaled to their complexity, get user approval after each section
5. **Write design doc** — save to project's plan directory and commit
6. **Transition to implementation** — invoke `requirements-framework:writing-plans` skill to create implementation plan

## Process Flow

```dot
digraph brainstorming {
    "Explore project context" [shape=box];
    "Ask clarifying questions" [shape=box];
    "Propose 2-3 approaches" [shape=box];
    "Present design sections" [shape=box];
    "User approves design?" [shape=diamond];
    "Write design doc" [shape=box];
    "design_approved satisfied" [shape=box, style=filled, fillcolor="#ccffcc"];
    "Invoke writing-plans skill" [shape=doublecircle];

    "Explore project context" -> "Ask clarifying questions";
    "Ask clarifying questions" -> "Propose 2-3 approaches";
    "Propose 2-3 approaches" -> "Present design sections";
    "Present design sections" -> "User approves design?";
    "User approves design?" -> "Present design sections" [label="no, revise"];
    "User approves design?" -> "Write design doc" [label="yes"];
    "Write design doc" -> "design_approved satisfied";
    "design_approved satisfied" -> "Invoke writing-plans skill";
}
```

**The terminal state is invoking `requirements-framework:writing-plans`.** Do NOT invoke any other implementation skill. The ONLY skill you invoke after brainstorming is writing-plans.

## The Process

**Understanding the idea:**
- Check out the current project state first (files, docs, recent commits)
- Ask questions one at a time to refine the idea
- Prefer multiple choice questions when possible, but open-ended is fine too
- Only one question per message — if a topic needs more exploration, break it into multiple questions
- Focus on understanding: purpose, constraints, success criteria

**Exploring approaches:**
- Propose 2-3 different approaches with trade-offs
- Present options conversationally with your recommendation and reasoning
- Lead with your recommended option and explain why

**Presenting the design:**
- Once you believe you understand what you're building, present the design
- Scale each section to its complexity: a few sentences if straightforward, up to 200-300 words if nuanced
- Ask after each section whether it looks right so far
- Cover: architecture, components, data flow, error handling, testing
- Be ready to go back and clarify if something doesn't make sense

## After the Design

**Documentation:**
- Write the validated design to the project's plan directory (e.g., `docs/plans/YYYY-MM-DD-<topic>-design.md` or `.claude/plans/`)
- Commit the design document to git

**Implementation:**
- Invoke the `requirements-framework:writing-plans` skill to create a detailed implementation plan
- Do NOT invoke any other skill. writing-plans is the next step.

## Requirements Integration

When this skill completes, it auto-satisfies the `design_approved` requirement. This means Edit/Write tools will no longer be blocked by the design gate (if your project has `design_approved` enabled).

## Plan Mode Behavior

When invoked inside plan mode:
- Write the design directly into the plan file. Do NOT create a separate design document.
- Skip the git commit step (step 5) — the plan file is your design doc.
- After design approval, continue writing the implementation plan in the same plan file.
- The `requirements-framework:writing-plans` invocation is optional in plan mode since you are already planning.

## Key Principles

- **One question at a time** — Don't overwhelm with multiple questions
- **Multiple choice preferred** — Easier to answer than open-ended when possible
- **YAGNI ruthlessly** — Remove unnecessary features from all designs
- **Explore alternatives** — Always propose 2-3 approaches before settling
- **Incremental validation** — Present design, get approval before moving on
- **Be flexible** — Go back and clarify when something doesn't make sense
