| instructions | Use this skill when the user wants to compare multiple implementation approaches. Generates N variants (default 3) using different agent profiles (concise, robust, readable, performant, testable), benchmarks each on error handling, readability, and conciseness, then ranks and selects a winner. Usage: /ab-compare "task description" [--variants 3] [--benchmark] |
| examples | [{"input":"/ab-compare \"add input validation to login form\"","output":"3 variants generated. Winner: robust-agent (score: 78/100)"},{"input":"/ab-compare \"implement retry with exponential backoff\" --variants 4","output":"4 variants compared. Winner: performant-agent (score: 82/100)"}] |

Generates multiple implementation variants for a task using different agent profiles, benchmarks each variant, and selects the best one.
/ab-compare "task description" [--variants 3] [--benchmark]
| Profile | Strategy |
|---|---|
| concise-agent | Minimal code, one-liners, built-in methods |
| robust-agent | Comprehensive error handling, edge cases |
| readable-agent | Self-documenting, clarity over brevity |
| performant-agent | Optimized, minimal allocations |
| testable-agent | Pure functions, DI, clear interfaces |
| Criterion | Weight | Description |
|---|---|---|
| Conciseness | 30% | Fewer lines = higher score |
| Error Handling | 35% | try/catch, null checks, throw |
| Readability | 35% | Line length, comments, naming |
