 ## Summary
 
+- **Default policy**: All tools `ask` — only explicitly whitelisted tools auto-allow
 - **File operations**: `read`, `glob`, `grep`, `edit`, `write` all allowed in workspace
 - **Nix operations**: Build/eval/flake commands auto-allowed (writes to store only)
 - **Linting & formatting**: All check commands auto-allowed
 - **System diagnostics**: Read-only system info auto-allowed
 - **Sensitive files**: Credentials, keys, and cloud configs are blocked
-- **Destructive operations**: `rm` requires explicit user confirmation
+- **Bash commands**: Read-only ops auto-allowed; `rm` requires confirmation; `sudo` blocked
-- **Privilege escalation**: `sudo` is completely blocked
 - **Scope control**: `task` and `external_directory` require approval
