claude-code-mastery-project-starter-kit: Command for Claude Code

Arguments: $ARGUMENTS

---

Step 0 — Resolve Source (Starter Kit)

Find the starter kit source directory:

1. If CWD has BOTH claude-mastery-project.conf AND .claude/commands/new-project.md → use CWD as $SOURCE
2. Else read ~/.claude/starter-kit-source-path → verify it still has both files
3. Else ask via AskUserQuestion: "Where is the starter kit cloned?" with a text input

Store as $SOURCE.

Step 1 — Registry Picker (Select Target)

1. Read ~/.claude/starter-kit-projects.json

   • If file doesn't exist or empty → error: "No projects found. Use /new-project to create one first."
   • If file is invalid JSON → error: "Project registry is corrupted. Check ~/.claude/starter-kit-projects.json."

2. Filter to projects whose path directory still exists on disk

3. If no valid projects remain → error: "No registered projects found on disk. Use /new-project to create one."

4. Display list with AskUserQuestion:

   • "Which project do you want to update?"
   • Options: up to 4 most recent projects (by createdAt), each showing: name — language/framework — path
   • If more than 4: the 4th option should be "Other (type a path)"

5. Store selected path as $TARGET

Validations (all must pass — stop with clear error if any fail)

1. $TARGET directory exists → if not: "Directory not found: $TARGET"
2. $TARGET is a git repo → run: git -C "$TARGET" rev-parse --is-inside-work-tree 2>/dev/null
   • If not a git repo: "This project must be a git repo. Run git init && git commit --allow-empty -m 'init' first."
3. $TARGET is NOT the starter kit itself (compare resolved paths of $SOURCE and $TARGET)
   • If same: "Cannot update the starter kit itself."
4. $TARGET is registered in ~/.claude/starter-kit-projects.json
   • If not registered: "This project isn't in the registry. Use /convert-project-to-starter-kit instead."
