Highlights

• 🚀 One command to productive — ccsk init and your repo is Claude-ready.
• 🎚️ Pick your kit version — an interactive picker lists available versions; stable by default, prereleases opt-in (--pre / --version). Discover with ccsk versions.
• 🧩 Plugin + materialized contract — installs the ccsk@ccsk-kit Claude Code plugin (the /ccsk: commands, agents, skills) and copies CLAUDE.md, .claude/rules, docs/, and .ccsk/ into your project.
• 📦 Fetches & caches — shallow-clones the kit and caches it at ~/.ccsk/kit/<version> for fast re-installs.
• 🔐 Auth-aware — detects SSH / gh CLI and guides you if access is missing (the kit repo is private).
• 🛟 Non-destructive re-init — never silently overwrites: an existing file is backed up to .bak (or kept, with the ccsk copy written alongside as .ccsk.bak). Your .ccsk/ memory is always preserved; uninstall keeps it by default (and backs it up before any purge).
• 🎨 Optional extras — tool setup (gh · RTK · context-mode · Serena MCP), ADD methodology, and design references — all skippable.
• 💻 Cross-platform & CI-friendly — macOS / Linux / Windows; -y for non-interactive runs.

Quick start

A global CLI tool, not a project dependency. Requires Node ≥ 20.

npm i -g @ccsk/cli
or: pnpm add -g @ccsk/cli · yarn global add @ccsk/cli · bun add -g @ccsk/cli
ccsk auth          # verify GitHub access (kit repo is private) ccsk versions      # see available kit versions (stable + beta) ccsk init          # install — pick a version when prompted claude             # open Claude Code /ccsk:plan <goal>  # start the Build Cadence (v2 kit)

How it works

ccsk init is auth-aware, cached, and non-destructive — it never silently overwrites a file you've edited (it asks how to handle conflicts and always keeps a copy — see Safe re-init & backups), preserves your .ccsk/ memory, and never touches your code. It also writes a fenced block to your .gitignore (AI artifacts ignored by default) and installs a Claude Code plugin.

Two things land — the plugin provides the /ccsk: commands, agents, and skills; the contract (CLAUDE.md, .claude/rules, docs/, .ccsk/) is materialized into your project (a plugin can't own project-root files):

See the ccsk-kit repo for the Build Cadence (Frame → Forge → Prove → Sign-off) and the full method.

Safe re-init & backups

Re-running ccsk init in an existing project is safe: it never silently overwrites a file you've touched. When kit files already exist, you get a three-way choice — applied to every conflicting file — and the install always proceeds (it never aborts midway):

• Overwrite — your existing file is backed up to <name>.<ext>.bak, then the ccsk version is written in its place. Your edits stay recoverable.
• Keep mine — your file is left untouched and the ccsk version is written alongside as <name>.<ext>.ccsk.bak, so you can diff or merge on your own terms.
• Cancel — abort the install (the escape hatch); your project is left exactly as-is.

Non-interactive runs (--yes, --force, or CI) default to the safe Overwrite-with-backup behavior — a file is never destroyed without a .bak copy first. Your .ccsk/ memory (plans, journals, ADRs, retros, milestones) is always preserved — never overwritten, never backed up away.

---

Kit versions & channels

The CLI is version-aware: stable by default, prereleases opt-in. A plain ccsk init (or --yes/CI) installs the latest stable kit; you reach a beta only via the interactive picker, --pre, or an exact --version.

ccsk versions                       # list available (remote) + cached + current
ccsk versions --all --pre           # include every prerelease
ccsk init                           # interactive: pick a version (default = latest stable)
ccsk init --pre                     # newest prerelease (e.g. the v2 beta)
ccsk init --version 2.0.0-beta-01   # an exact version (a leading v is fine too)

Heads-up (current state): the v2 kit (/ccsk: colon commands) ships as the prerelease 2.0.0-beta-01; the latest stable is v1.1.0 (older /ccsk-plan hyphen commands). So a default ccsk init installs v1.1.0 — use --pre / --version 2.0.0-beta-01 / the picker to get v2. A bare ccsk update never auto-downgrades: if you're on a newer beta it stays put.

ccsk init --version 1.2.0 --no-add -y   # pin a kit version, skip ADD, non-interactive
ccsk init --pre                          # opt into the newest prerelease kit
ccsk update --no-plugin                  # refresh CLI + templates, leave the plugin
ccsk uninstall --purge-memory            # remove everything (memory backed up first)

update is a three-layer, non-aborting operation: it self-updates the CLI, re-materializes the kit templates (preserving your memory), and runs claude plugin update ccsk — all pinned to one resolved version so the plugin and templates never drift. The CLI self-update always runs, but the kit layers (templates + plugin) are materialized only in an existing ccsk project (a dir with .ccsk/ or materialized .claude/skills/ccsk-*) — so running ccsk update in an unrelated directory won't scatter kit files there. To install into a fresh dir anyway, name it with --path <dir> or pass --force.

Tool setup

ccsk init offers an optional setup pass (skip with --no-setup) that wires, idempotently and without aborting on failure:

• gh CLI — installed if missing (for GitHub auth to the private kit repo).
• RTK-AI — installs rtk and runs rtk init to enable its Claude Code hook.
• context-mode — registers the context-mode MCP server (+ prints the manual plugin steps).
• Serena — registers the Serena MCP server (skipped if uv/uvx is absent).

The ccsk plugin itself is installed by init (skip with --no-plugin); if the claude CLI isn't found, init prints a hint and you can re-run later.

---

Works with ADD

ADD (AI-Driven Development) is a methodology where AI writes the code while humans own direction and verification — Specify → Scenarios → Contract → Tests → Build → Verify. ccsk init can install it (npx @pilotspace/add; skip with --no-add):

• ccsk scaffolds Claude Code's plugin (commands/agents/skills) + rules, docs, and .ccsk/ memory.
• ADD adds the specification-first, test-driven loop on top.

---

Privacy

• init writes a fenced block to your project .gitignore that ignores AI artifacts (.ccsk/, loop logs, …) by default, with commented opt-in lines to commit the contract/memory for team sharing.
• init records the installed version locally (~/.ccsk/install.json) and sends optional, fire-and-forget install telemetry (GitHub username + an email you may decline). No code is ever read or uploaded.

Troubleshooting

| Issue | Fix | | --- | --- | | command not found: ccsk | Add your global bin to PATH. npm: $(npm prefix -g)/bin. bun: ~/.bun/bin. | | Permission denied (publickey) / GitHub authentication required | Run ccsk auth and follow the steps (SSH keys, or gh auth login). | | Plugin step skipped | The claude CLI wasn't found — install Claude Code, then re-run ccsk init. | | No stable kit release yet in CI | A non-interactive run won't auto-pick a prerelease — pass --version <v> or --pre. | | Spinner shows raw text | Expected in CI or when piped — animations degrade gracefully. | | Something else is off | Run ccsk doctor, or CCSK_DEBUG=1 ccsk <cmd> for stack traces. |
