Guidelines for testing and validating newly created modes to ensure they function correctly and integrate well with the Roo Code ecosystem. Mode slug is unique and follows naming conventions No spaces, lowercase, hyphens only All required fields are present and non-empty slug, name, roleDefinition, groups No customInstructions field in .roomodes All instructions must be in XML files in .roo/rules-[slug]/ File restrictions use valid regex patterns . your_file_regex_here ]]> whenToUse clearly differentiates from other modes Compare with existing mode descriptions XML files are well-formed and valid No syntax errors, proper closing tags Instructions follow XML best practices Semantic tag names, proper nesting Examples use correct tool syntax Tool parameters match current API File paths in examples are consistent Use project-relative paths Mode appears in mode list Switch to the new mode and verify it loads Tool permissions work as expected Try using each tool group and verify access File restrictions are enforced Attempt to edit allowed and restricted files Mode handles edge cases gracefully Test with minimal input, errors, edge cases Verify mode appears in available modes list Check that mode metadata displays correctly Confirm mode can be activated I've created the mode configuration. Can you see the new mode in your mode list? Yes, I can see the new mode and switch to it No, the mode doesn't appear in the list The mode appears but has errors when switching ]]> Use read tools on various files All read operations should work Try editing allowed file types Edits succeed for matching patterns Try editing restricted file types FileRestrictionError for non-matching files Execute main workflow from start to finish Test each decision point Verify error handling Check completion criteria Orchestrator mode compatibility Mode switching functionality Tool handoff between modes Consistent behavior with other modes Mode doesn't appear in list Syntax error in YAML Invalid mode slug File not saved Check YAML syntax, validate slug format File restriction not working Invalid regex pattern Escaping issues in regex Wrong file path format Test regex pattern, use proper escaping Mode not following instructions Instructions not in .roo/rules-[slug]/ folder XML parsing errors Conflicting instructions Verify file locations and XML validity Verify instruction files exist in correct location .roo true ]]> Check mode configuration syntax .roomodes ]]> Test file restriction patterns . your_file_pattern_here ]]> Test incrementally as you build the mode Start with minimal configuration and add complexity Document any special requirements or dependencies Consider edge cases and error scenarios Get feedback from potential users of the mode
