Agent Skills: Design Solution

Converge on a single recommended solution after brainstorming options. Use when you have multiple candidate approaches and need to analyze trade-offs, select one, and define decision criteria before planning.

Converge on a single recommended solution after brainstorming options. Use when you have multiple candidate approaches and need to analyze trade-offs, select one, and define decision criteria before planning.

Design Solution

Converge from multiple options to a single recommended approach.

Position in Workflow

Step 3 of development workflow:

  1. /research - Understand problem and constraints
  2. /brainstorm-solutions - Explore solution space
  3. /design-solution - Converge on a single solution (THIS)
  4. Plan, code, review, ship

Core Principle

Decide deliberately. Evaluate trade-offs, align to constraints, and pick the best fit.

Input

Default: Use the options from the current conversation.

If argument provided:

  • File path: Read the file for brainstorming output
  • GitHub issue: Fetch with gh issue view $ARG --comments

Workflow

1. Reconfirm Context

  • Restate the problem, constraints, and success criteria.
  • Identify any missing information that blocks a decision.

2. Evaluate Options

For each option, assess:

  • Pros: Benefits and what it enables
  • Cons: Risks and complexity
  • Codebase fit: Alignment with existing patterns
  • Effort: Low/Medium/High
  • Reversibility: Easy/Moderate/Hard to change later

3. Decide

  • Rank options against success criteria.
  • Select a recommended option.
  • State conditions that would change the decision.

4. Capture Open Questions

List unknowns that must be resolved before planning.

Output Format

## Solution Decision

### Context Summary
[Brief restatement of problem and key constraints]

### Decision Criteria
[What matters most: performance, time, simplicity, extensibility, etc.]

---

### Option Evaluation

#### Option 1: [Name] - Recommended
[Description]

**Pros:**
- ...

**Cons:**
- ...

**Codebase fit:** [How it aligns with existing patterns]
**Effort:** [Low/Medium/High]
**Reversibility:** [Easy/Moderate/Hard]

#### Option 2: [Name]
[Same structure]

#### Option 3: [Name]
[Same structure]

---

### Recommendation
[Why the recommended option wins, and when you would choose differently]

### Open Questions
[Anything that could change the recommendation]

### Next Step
Ready to plan implementation. Enter Plan Mode or run `/plan`.

Common Mistakes

| Mistake | Fix | |---------|-----| | Skipping decision criteria | State criteria before evaluating | | Over-weighting novelty | Prefer codebase fit and simplicity | | Ignoring reversibility | Consider how hard it is to change later | | Decision without evidence | Call out unknowns explicitly |

What NOT to Do

  • Do NOT re-brainstorm options
  • Do NOT proceed to planning without a chosen option
  • Do NOT hide assumptions or uncertainties
  • Do NOT ignore codebase constraints
