Design Explore

design-explore

Use this skill when the user asks for "design", "architecture", "approach", "options", "trade-offs", "how should we do X", or when task classifier returns level >= 3.

Workflow

1. Discover prior art — memory_recall(query="<task keywords>", mode="index", limit=10) + analogize(query="<task description>", exclude_project=None) — check if similar decision was made before.

2. Generate 2-4 options for the design space. For each option, fill:

   • Core approach (1 sentence)
   • Implementation sketch (3-5 lines)
   • Pros (3 bullets)
   • Cons (2-3 bullets)
   • Unknowns (what we don't yet know)

3. Build criteria matrix — list 3-5 criteria that matter (e.g. performance, maintainability, migration risk, team familiarity). Rate each option 1-5 per criterion.

4. Pick one with justification referring to matrix. Name what was discarded and why.

5. Save — save_decision(title, options, criteria_matrix, selected, rationale, discarded, project).

6. Only then proceed to implementation — with a clear decision in memory for next session.

Output template

## Decision: {title}

### Prior art
{memory_recall/analogize results — 1-2 sentences}

### Options

#### 1. {option name}
- **Approach:** {1 sentence}
- **Implementation:** {sketch}
- **Pros:** {3 bullets}
- **Cons:** {3 bullets}
- **Unknowns:** {bullets}

#### 2. {option name}
... (same structure)

### Criteria matrix

| Criterion | Option 1 | Option 2 | ... |
|---|:-:|:-:|:-:|
| {criterion} | 5 | 3 | ... |

### Selected: {option name}

{rationale — 2-3 sentences referencing matrix}

### Discarded

- **{option name}**: {1-sentence reason}

When NOT to use

• L1/L2 tasks (quick fixes, straightforward additions) — overkill, just do it.
• Single-option situations (no real trade-off).
• Implementation bugs (debug first, design later).
