Individual skill

harness-test-drive

Test-drives coding agents (Claude Code, Codex, Gemini CLI) on tasks mined from the user's own git history: each agent gets a past commit message in a fresh copy of the repo, and the repo's own tests score how many tasks it completes, dollars per task, minutes, and change size. Use when the user asks which coding agent or harness works best on their codebase; wants to compare or benchmark agents on their own repository instead of trusting leaderboards such as SWE-bench; wants to trial one agent against another before switching; or asks what each agent costs per fixed bug. Spends money: the harness CLIs call their model providers, so a dollar cap is required. The scripts make no network calls.
