+description: Test apply_diff tool error handling with non-existent patterns
+argument-hint: [search-pattern]
+---
+
+
+Test the apply_diff tool's error handling by attempting to replace a pattern that does not exist in the target file.
+Target File: ${testFile.content}
+Search pattern: "PATTERN_THAT_DOES_NOT_EXIST_xyz123"
+Replacement: "REPLACEMENT_xyz123"
+
+
+
+This command verifies that apply_diff correctly handles and reports errors when:
+- A search pattern is not found in the target file
+- The tool gracefully fails with an informative error message
+- Error handling works as expected for debugging workflows
+
+
+
+
+ Execute apply_diff directly
+
+ Call apply_diff on the specified file with a non-existent search pattern.
+ Do NOT analyze the file first - the goal is to test error handling.
+
+
+
+
+ Observe the error response
+
+ The apply_diff tool should report that the pattern was not found.
+ This is the EXPECTED outcome - not a failure of the test.
+
+
+
+
+ Report results
+
+ Confirm whether the error handling worked correctly by reporting:
+ - The error message received
+ - Whether the tool behaved as expected
+
+
+
+
+
+
+ - YOU MUST call the apply_diff tool - this is non-negotiable
+ - Use the EXACT search pattern provided (or default: "PATTERN_THAT_DOES_NOT_EXIST_xyz123")
+ - Do NOT use write_to_file or any other file modification tool
+ - Do NOT analyze the file contents before calling apply_diff
+ - Do NOT refuse to call the tool - error handling verification is the purpose
+
+
+
+ PATTERN_THAT_DOES_NOT_EXIST_xyz123
+ REPLACEMENT_xyz123
+
+
+
+
+
+ Use this structure for the apply_diff call:
+ - path: The file specified by the user
+ - diff: A SEARCH/REPLACE block with the non-existent pattern
+
+
+
+ \`\`\`
+ <<<<<<< SEARCH
+ :start_line:1
+ -------
+ PATTERN_THAT_DOES_NOT_EXIST_xyz123
+ =======
+ REPLACEMENT_xyz123
+ >>>>>>> REPLACE
+ \`\`\`
+
+
+
+
+
+ The test succeeds when apply_diff returns an error indicating the pattern was not found.
+ This confirms the tool's error handling is working correctly.
+
+
+
+ After executing, report:
+ - Whether apply_diff was called: YES/NO
+ - Error message received: [actual error]
+ - Error handling status: WORKING/FAILED
+
+
+
+
+ - Only use the apply_diff tool
+ - Accept that "pattern not found" errors are the expected result
+ - Do not attempt to "fix" the test by finding real patterns
+ - This is a diagnostic/testing command, not a production workflow
