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…

What this skill can do

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'dx-harness' ] || [ -L ~/.agents/skills/'dx-harness' ]; then echo 'A skill folder named dx-harness already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/pproenca/dot-skills' "$d" && git -C "$d" checkout --quiet 'cf93c57cac89d6fc3e4194686000411567f5caf3' -- 'skills/.experimental/dx-harness' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/.experimental/dx-harness' ~/.agents/skills/'dx-harness' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'dx-harness' ~/.claude/skills/'dx-harness' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
