 ## Workflow
 
-1.  **Identify User Intent:** specific site (YouTube), specific type (Recipe), or general clipping?
-2.  **Check Existing Bases:** The user likely has a "Base" schema defined in `Templates/Bases/`.
-    *   **Action:** Read `Templates/Bases/*.base` to find a matching category (e.g., `Recipes.base`).
-    *   **Action:** Use the properties defined in the Base to structure the Clipper template properties.
-    *   See [references/bases-workflow.md](references/bases-workflow.md) for details.
-3.  **Fetch & Analyze Reference URL:** Validate variables against a real page.
-    *   **Action:** Ask the user for a sample URL of the content they want to clip (if not provided).
-    *   **Action:** Use `WebFetch` to retrieve the page HTML.
-    *   **Action:** Analyze the HTML for Schema.org JSON, Meta tags, and CSS selectors.
-    *   See [references/analysis-workflow.md](references/analysis-workflow.md) for analysis techniques.
-4.  **Draft the JSON:** Create a valid JSON object following the schema.
-    *   See [references/json-schema.md](references/json-schema.md).
-5.  **Verify Variables:** Ensure the chosen variables (Preset, Schema, Selector) exist in your analysis.
-    *   See [references/variables.md](references/variables.md).

+## Selector Verification Rules
+
+- **Always verify selectors** against live page content before responding.
+- **Never guess selectors.** If the DOM cannot be accessed or the element is missing, ask for another URL or a screenshot.
+- **Prefer stable selectors** (data attributes, semantic roles, unique IDs) over fragile class chains.
+- **Document the target element** in your reasoning (e.g., "About sidebar paragraph") to reduce mismatch.

 To ensure your template works correctly, you must validate that the target page actually contains the data you want to extract.
 
 ## 1. Fetch the Page
-Use the `WebFetch` tool to retrieve the content of a representative URL provided by the user.

 ## 2. Analyze the Output
 
 ### Check for Schema.org (Recommended)
+
 Look for `<script type="application/ld+json">`. This contains structured data which is the most reliable way to extract info.

 Compare the available data from your analysis with the properties required by the user's Base (see `references/bases-workflow.md`).
