npx skills add a5c-ai/babysitter --skill solution-comparator --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# Solution Comparator Skill ## Purpose Compare multiple algorithm solutions against the same test cases to verify correctness and benchmark performance. ## Capabilities - Run solutions against same test cases - Performance benchmarking and comparison - Output diff analysis - Find minimal failing test case - Memory usage comparison - Time complexity validation ## Target Processes - correctness-proof-testing - complexity-optimization - upsolving - algorithm-implementation ## Comparison Modes 1. **Correctness**: Compare outputs against a known-correct solution 2. **Performance**: Benchmark execution time across solutions 3. **Stress Testing**: Run with random large inputs to find discrepancies 4. **Minimal Counter-example**: Binary search to find smallest failing case ## Input Schema ```json { "type": "object", "properties": { "solutions": { "type": "array", "items": { "type": "object", "properties": { "name": { "type": "string" }, "code": { "type": "string" }, "language": { "type": "string" } } } }, "testCases": { "type": "array" }, "mode": { "type": "string", "enum": ["correctness", "performance", "stress", "minimal"] }, "oracleSolution": { "type": "string" }, "timeout": { "type": "

What does the solution-comparator skill do?
Compare multiple solutions for correctness and performance
How do I install it?
Run `npx skills add a5c-ai/babysitter --skill solution-comparator --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From a5c-ai/babysitter, a repository with 1,642 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
