Cc Arch Hands

cc-arch-hands (`cah`)

Installer for the artifacts that turn Claude Code into an architect's workshop: per-model slash-commands, per-model delegated sub-agents, and skills. Zero runtime dependencies — only Node.js built-ins.

npx cc-arch-hands install        # that's it — installs commands, agents & skills into ~/.claude/

Other ways to run: [npm global install](#quick-start), [from source](#from-source). Full command reference in [Use](#use).

What it installs

Three kinds of Claude Code artifacts under `~/.claude/` (commands, agents, skills), all generated from a single model registry so they stay in lockstep — plus the three companion bins that some skills use as hooks or statusLine commands, copied into `~/.claude/cah-bin/` at install time.

The artifacts:

• per-model slash-commands (43) under ~/.claude/commands/,
• per-model sub-agents (43) under ~/.claude/agents/,
• skills (10) under ~/.claude/skills/,
• companion bins under ~/.claude/cah-bin/ (since 0.4.0).

Optional artifacts are installed only when requested:

• Codex custom agents (30) under ~/.codex/agents/, via --codex-agents.
• Agent-tree skills (agent, agent-new — 2) under ~/.claude/skills/, via --agent-tree.

**Since 0.4.0:** `cah install` copies the companion bins into `~/.claude/cah-bin/` and `settings.json` references them by absolute path (`node "/.claude/cah-bin/bin/cah-status.js"`) rather than a bare PATH name. This means `/clock` and `/checkpoint-watch` keep working even if the `cc-arch-hands` npm package is moved, relinked, or uninstalled. Re-running `/clock` (or `/checkpoint-watch`) migrates a pre-0.4.0 bare-name command to the new absolute path automatically.

The companion bins:

• cah (and its alias cc-arch-hands) — the installer CLI itself.
• cah-checkpoint-hint — Stop hook
