Subject: [PATCH 1/3] feat: add automatic worktree support via .worktreeinclude
 and post-checkout hook
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Three-layer worktree support ensures Kit workflows work seamlessly in
git worktrees without manual re-initialization:

1. .worktreeinclude — Claude Code native mechanism copies gitignored files
2. post-checkout hook — copies .agent/ and bridge dirs from main worktree
3. --skip-worktree flag — opt-out for users who don't need worktree support

New lib/worktree.js module with generateWorktreeInclude() and
installPostCheckoutHook(). Hook uses cp -RP for symlink safety and
provenance markers for idempotent operation.

 Bridge files are local-only artifacts, auto-regenerated by `kit init` and `kit update`. They are not tracked in git.
 
-For worktree users: run `kit init` in each worktree to regenerate bridges. This takes under 100ms and is idempotent.
+### Worktree Support
+
+Kit automatically configures worktree support during `kit init`:
+
+**Claude Code worktrees** — A `.worktreeinclude` file lists `.agent/` and bridge directories. Claude Code copies these files automatically when creating worktrees.
+
+**Manual worktrees** (`git worktree add`) — A `post-checkout` git hook copies `.agent/` from the main worktree and regenerates bridges. User customizations (decisions, rules, project identity) are preserved.
+
+Both mechanisms are installed automatically. No user configuration needed.
+
+To skip: `kit init --skip-worktree`
+
+> **Note:** If your project uses Husky or another hook manager that already has a `post-checkout` hook, Kit will not overwrite it. You can manually add Kit's worktree setup to your existing hook.

Subject: [PATCH 3/3] fix(review): address Gemini Code Assist findings in
 worktree hook
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

1. Prevent nested .agent/.agent/ — use mkdir -p + cp -RP with /. source
   pattern, consistent with bridge directory copy below.
2. Generate bridge dir list dynamically from IDE_BRIDGE_DIRS constant
   instead of hardcoding — eliminates drift risk.
