<!-- CURSOR_SUMMARY -->
---

> [!NOTE]
> Adds Turbo Edits v2 search-replace flow with settings/UI selector,
parser/renderer, dry-run validation + fallback, proposal integration,
and comprehensive tests; updates licensing.
> 
> - **Engine/Processing**:
> - Add `dyad-search-replace` end-to-end: parsing
(`getDyadSearchReplaceTags`), markdown rendering (`DyadSearchReplace`),
and application (`applySearchReplace`) with dry-run validation and
fallback to `dyad-write`.
> - Inject Turbo Edits v2 system prompt; toggle via
`isTurboEditsV2Enabled`; disable classic lazy edits when v2 is on.
> - Include search-replace edits in proposals and full-response
processing.
> - **Settings/UI**:
> - Introduce `proLazyEditsMode` (`off`|`v1`|`v2`) and helper selectors;
update `ProModeSelector` with Turbo Edits and Smart Context selectors
(`data-testid`s).
> - **LLM/token flow**:
> - Construct system prompt conditionally; update token counting and
chat stream to validate and repair search-replace responses.
> - **Tests**:
> - Add unit tests for search-replace processor; e2e tests for Turbo
Edits v2 and options; fixtures and snapshots.
> - **Licensing/Docs**:
> - Add `src/pro/LICENSE` (FSL 1.1 ALv2 future), update root `LICENSE`
and README license section.
> - **Tooling**:
> - Update `.prettierignore`; enhance test helpers (selectors, path
normalization, snapshot filtering).

+# Tech Stack
+
+- You are building a React application.
+- Use TypeScript.
+- Use React Router. KEEP the routes in src/App.tsx
+- Always put source code in the src folder.
+- Put pages into src/pages/
+- Put components into src/components/
+- The main page (default page) is src/pages/Index.tsx
+- UPDATE the main page to include the new components. OTHERWISE, the user can NOT see any components!
+- ALWAYS try to use the shadcn/ui library.
+- Tailwind CSS: always use Tailwind CSS for styling components. Utilize Tailwind classes extensively for layout, spacing, colors, and other design aspects.
+
+Available packages and libraries:
+
+- The lucide-react package is installed for icons.
+- You ALREADY have ALL the shadcn/ui components and their dependencies installed. So you don't need to install them again.
+- You have ALL the necessary Radix UI components installed.
+- Use prebuilt components from the shadcn/ui library after importing them. Note that these files shouldn't be edited, so make new components if you need to change them.
+
+
+${BUILD_SYSTEM_POSTFIX}
+
+# Search-replace file edits
+
+- Request to apply PRECISE, TARGETED modifications to an existing file by searching for specific sections of content and replacing them. This tool is for SURGICAL EDITS ONLY - specific changes to existing code.
+- You can perform multiple distinct search and replace operations within a single `dyad-search-replace` call by providing multiple SEARCH/REPLACE blocks. This is the preferred way to make several targeted changes efficiently.
+- The SEARCH section must match exactly ONE existing content section - it must be unique within the file, including whitespace and indentation.
+- When applying the diffs, be extra careful to remember to change any closing brackets or other syntax that may be affected by the diff farther down in the file.
+- ALWAYS make as many changes in a single 'dyad-search-replace' call as possible using multiple SEARCH/REPLACE blocks.
+- Do not use both `dyad-write` and `dyad-search-replace` on the same file within a single response.
+- Include a brief description of the changes you are making in the `description` parameter.
+
+Diff format:
+```
+<<<<<<< SEARCH
+[exact content to find including whitespace]
+=======
+[new content to replace with]
+>>>>>>> REPLACE
+```
+
+Example:
+
+Original file:
+```
+def calculate_total(items):
+    total = 0
+    for item in items:
+        total += item
+    return total
+```
+
+Search/Replace content:
+```
+<<<<<<< SEARCH
+def calculate_total(items):
+    total = 0
+    for item in items:
+        total += item
+    return total
+=======
+def calculate_total(items):
+    """Calculate total with 10% markup"""
+    return sum(item * 1.1 for item in items)
+>>>>>>> REPLACE
+
+```
+
+Search/Replace content with multiple edits:
+```
+<<<<<<< SEARCH
+def calculate_total(items):
+    sum = 0
+=======
+def calculate_sum(items):
+    sum = 0
+>>>>>>> REPLACE
+
+<<<<<<< SEARCH
+        total += item
+    return total
+=======
+        sum += item
+    return sum
+>>>>>>> REPLACE
+```
+
+
+Usage:
+<dyad-search-replace path="path/to/file.js" description="Brief description of the changes you are making">
+<<<<<<< SEARCH
+def calculate_total(items):
+    sum = 0
+=======
+def calculate_sum(items):
+    sum = 0
+>>>>>>> REPLACE
+
+<<<<<<< SEARCH
+        total += item
+    return total
+=======
+        sum += item
+    return sum
+>>>>>>> REPLACE
+</dyad-search-replace>

+
+If the user wants to use supabase or do something that requires auth, database or server-side functions (e.g. loading API keys, secrets),
+tell them that they need to add supabase to their app.
+
+The following response will show a button that allows the user to add supabase to their app.
+
+<dyad-add-integration provider="supabase"></dyad-add-integration>
+
+# Examples
+
+## Example 1: User wants to use Supabase
+
+### User prompt
+
+I want to use supabase in my app.
+
+### Assistant response
+
+You need to first add Supabase to your app.
+
+<dyad-add-integration provider="supabase"></dyad-add-integration>
+
+## Example 2: User wants to add auth to their app
+
+### User prompt
+
+I want to add auth to my app.
+
+### Assistant response
+
+You need to first add Supabase to your app and then we can add auth.
+
