-# Review Findings - PR #20361
-
-## Summary
-
-The PR implements "auto-add to policy by default" with workspace-first
-persistence and rule narrowing for edit tools. The core logic is sound, but
-there are several violations of the "Strict Development Rules".
-
-## Actionable Findings
-
-### 1. Type Safety (STRICT TYPING Rule)
-
-- **`packages/core/src/scheduler/policy.test.ts`**: Still uses `any` for
-  `details` in 'should narrow edit tools with argsPattern' test (Line 512).
-- **`packages/cli/src/ui/components/messages/ToolConfirmationMessage.tsx`**: The
-  `initialIndex` calculation logic uses `confirmationDetails` which is complex.
-  Ensure no `any` is leaked here.
-
-### 2. React Best Practices (packages/cli)
-
-- **Dependency Management**: In `ToolConfirmationMessage.tsx`, the `useMemo`
-  block for `question`, `bodyContent`, etc. (Lines 418-444) includes many new
-  dependencies. Ensure `initialIndex` is calculated correctly and doesn't
-  trigger unnecessary re-renders.
-- **Reducers**: The `initialIndex` is derived state. While `useMemo` is
-  acceptable here, verify if this state should be part of a larger reducer if
-  the confirmation UI becomes more complex.
-
-### 3. Core Logic Placement
-
-- **Inconsistency**: Narrowing for edit tools is implemented in both
-  `scheduler/policy.ts` and individual tools (`write-file.ts`, `edit.ts`).
-  - _Recommendation_: Centralize the narrowing logic in the tools via
-    `getPolicyUpdateOptions` and ensure `scheduler/policy.ts` purely respects
-    what the tool provides, rather than duplicating the
-    `buildFilePathArgsPattern` call.
-
-### 4. Testing Guidelines
-
-- **Snapshot Clarity**: The new snapshot for `ToolConfirmationMessage` includes
-  a large block of text. Ensure the snapshot specifically highlights the change
-  in the selected radio button (the `●` indicator).
-- **Mocking**: In `persistence.test.ts`, ensure `vi.restoreAllMocks()` or
-  `vi.clearAllMocks()` is consistently used to avoid pollution between the new
-  workspace persistence tests and existing ones.
-
-### 5. Settings & Documentation
-
-- **RequiresRestart**: The `autoAddToPolicyByDefault` setting has
-  `requiresRestart: false`. Verify if the `ToolConfirmationMessage` correctly
-  picks up setting changes without a restart (it should, as it uses the
-  `settings` hook).
-- **Documentation**: Ensure this new setting is added to
-  `docs/get-started/configuration.md` as per the general principles.
-
-## Directive
-
-Fix all findings above, prioritizing strict typing and removal of duplicate
-narrowing logic.
