dx-harness
Developer-experience friction auditing and fixing — slow onboarding, repeated manual setup steps, missing bootstrap/reset/seed scripts, undiscoverable conventions. Audits the repo, scores findings, scaffolds canonical fixes (bootstrap.sh, reset.sh, seed.sh, AGENTS.md, task-runner entries), then verifies the harness end-to-end in a scratch worktree against a 60-second time-to-first-commit target. Triggers on phrases like "audit dx", "fix dev friction", "time to first commit", "set up the harness", "I keep doing X manually", "every time I reset the db I have to...", and on new-repo bootstrapping. Even if the user doesn't say "DX" — if they describe a repeated manual chore in their dev loop, this skill applies.
