devlens-installer

Interactive installer for the DevLens skill.

One command, no shell scripts:

npx devlens-installer

It asks which harness(es) you use (Command Code, Claude Code, Codex, Gemini CLI, OpenCode) and which components you want (core skill + per-harness wrapper commands), shows you the exact install plan, and installs everything for the selected harness in one go.

What it installs

• Core skill — SKILL.md, commands/, references/, scripts/, templates/ → each selected harness's skills directory (e.g. ~/.commandcode/skills/devlens/).
• Wrapper commands — the short aliases (/learn, /ask, /debug, /quiz, …) → each selected harness's commands directory (e.g. ~/.commandcode/commands/), only when that harness has an adapter with wrappers.

Trust & safety

• No opaque shell script — the installer is a plain Node.js package you run with npx; you see exactly what it will copy before anything is written.
• Nothing is ever deleted; re-running is safe and idempotent.
• Every copy reports source → destination.

Usage after install

/devlens tour          # get the lay of the land
/devlens learn         # start building in learning units

The plan → learn loop: /plan <task> → press esc (Cancel — the plan stays saved) → /devlens learn reads the saved plan and drives implementation with checkpoints.

Development

npm run build   # stage the skill tree into bundle/ (run before publishing)
npm run test    # syntax-check all files
npm publish     # from this directory, after bumping the version
