+**Optional — wire hooks in one shot.** Re-run with `-AutoDetect` (PowerShell) / `--auto-detect` (Bash):
 
 ```powershell
-# Windows
 .\scripts\install.ps1 D:\path\to\your\project -AutoDetect
-
-# macOS / Linux
-./scripts/install.sh /path/to/your/project --auto-detect
 ```
 
-`-AutoDetect` looks for `.claude/` or `.kiro/` and writes the Stop / agentStop hook so the IDE reminds AI to sync `features.json` after every turn. Existing user entries are untouched, reruns are idempotent, and `-UninstallHooks` cleans up. For manual setup or per-platform docs see [`hooks/README.md`](./hooks/README.md).
