Skill Creator

Skill Creator helps you build Claude Code skills step by step. It presents a guided Create mode where you write skill code, define inputs and outputs, and attach example prompts. The tool reads your project files, scaffolds handlers, and generates a local dev environment so you can run the skill and inspect logs without manual setup.

Eval mode runs test suites against your skill: it sends batches of prompts, records responses, and calculates concrete metrics like accuracy, response time, and failure rate. Improve mode applies targeted edits — you can generate new test cases, tweak prompt templates, or swap handlers, then re-run the same tests to compare results. The interface shows diffed outputs and highlights regressions.

Benchmark mode runs A/B comparisons across versions and records historical performance. You can export CSVs of results, map metrics to releases, and set pass/fail gates for CI. The tool also packages a production-ready skill bundle you can publish or deploy.

For example, a support team can use Skill Creator to build an FAQ skill, run dozens of real tickets through Eval, iterate prompts in Improve, and run a Benchmark to confirm the new version reduces incorrect answers — all without switching between editors, test runners, and spreadsheets.
