+## When to Use
+
+Use when a task requires tools whose names, capabilities, or argument shapes are not already clear. This is especially useful when many tools are available or a previous call failed because the wrong tool or parameters were selected.
+
+## Procedure
+
+1. Translate the request into required capabilities such as reading, searching, editing, executing, browsing, or verifying.
+2. Search the tool index for those capabilities and inspect the returned tool descriptions and schemas.
+3. Prefer one direct tool over a chain of indirect tools when it can complete the operation and provide evidence.
+4. Check required parameters, identifiers, path rules, side effects, and approval requirements before calling the tool.
+5. Make a small read-only probe when the environment or target is uncertain.
+6. Execute the selected action, inspect the result, and only broaden the tool search if the result shows a concrete capability gap.
+
+## Pitfalls
+
+- Do not guess tool names or argument keys from memory when the index or schema is available.
+- Do not load unrelated tool groups into context.
+- Do not repeat the same failed call without changing the arguments or strategy.
+- Do not use a broad shell or browser workaround when a scoped native tool already owns the operation.
+
+## Verification
+
+- The chosen tool directly matches the required capability.
+- Required arguments follow the exposed schema.
+- The result contains evidence of the requested effect or a specific error that guides the next step.
