New project: $ARGUMENTS

1. Name. It must be kebab-case (a-z, 0-9, -). If the name is missing or invalid, ask for one. Refuse if a folder with that name already exists.
2. Location. You must be in the workspace root, the folder that contains this .claude/. Otherwise, stop and say so.
3. Create the project:

   mkdir <name> && cd <name> && git init -b main

   • .gitignore:

     .claude/runs/
     .claude/worktrees/
     .claude/settings.local.json
     .DS_Store
     .idea/
     .vscode/
     *.log

   • CLAUDE.md:

     # <name>
     
     Specs: docs/specs/ (start with /dev-workflow:spec-interview). Plans: docs/plans/.
     
     ## Commands
     <!-- Filled in by milestone M0: build, test, run. -->

4. Enable the workflow plugin at project scope. This writes <name>/.claude/settings.json, which gets committed so every clone has the plugin:

   cd <name>
   claude plugin marketplace add cenron/claude-kit --scope project
   claude plugin install dev-workflow@claude-kit --scope project

   If either command fails (offline, for example), report the error and continue. The user can rerun it later.
5. Make the architect the project's default agent. Merge "agent": "dev-workflow:architect" into <name>/.claude/settings.json, keeping the keys the plugin commands wrote. After that, a plain claude in the project starts as the architect (Opus, high effort, with the default Claude Code prompt).
6. Don't commit. Tell the user to run cd <name> && claude, then /dev-workflow:spec-interview <idea>, and later /dev-workflow:milestone M0 in a fresh session.
