MVP 2 Sprint 3 Completion Summary

🎯 Sprint Overview

Goal: Transform Gradio UI to display comprehensive PlannedStep information including tool details, prompt templates, and execution guidance.

Duration: Completed in ~4 hours Status: ✅ COMPLETED SUCCESSFULLY

📋 Tasks Completed

✅ Task 30: Implement format_planned_step_for_display Helper Function

Duration: 60 minutes | Status: COMPLETED

Implementation Highlights:

• ✅ Created format_planned_step_for_display() function in app.py
• ✅ Transforms PlannedStep objects into structured dictionaries for Gradio JSON display
• ✅ Handles empty tags and variables gracefully with "N/A" and "None" fallbacks
• ✅ Comprehensive test coverage with 6 test cases covering all scenarios

Key Features:

def format_planned_step_for_display(step: PlannedStep) -> Dict[str, Any]:
    return {
        "ACTION PLAN": f"Use Tool '{step.tool.name}' with Prompt '{step.prompt.name}'",
        "Tool Details": {
            "ID": step.tool.tool_id,
            "Name": step.tool.name,
            "Description": step.tool.description,
            "Tags": ", ".join(step.tool.tags) if step.tool.tags else "N/A",
            "Invocation Command": step.tool.invocation_command_stub
        },
        "Prompt Details": {
            "ID": step.prompt.prompt_id,
            "Name": step.prompt.name,
            "Description": step.prompt.description,
            "Template String": step.prompt.template_string,
            "Required Input Variables": ", ".join(step.prompt.input_variables) if step.prompt.input_variables else "None",
            "Difficulty Level": step.prompt.difficulty_level,
            "Tags": ", ".join(step.prompt.tags) if step.prompt.tags else "N/A",
            "Target Tool ID": step.prompt.target_tool_id
        },
        "Relevance Score": step.relevance_score if step.relevance_score else "Not calculated"
    }

✅ Task 31: Update handle_find_tools and Gradio UI Output Component

Duration: 90 minutes | Status: COMPLETED

Implementation Highlights:

• ✅ Updated handle_find_tools() to use format_planned_step_for_display() for each PlannedStep
• ✅ Enhanced UI component label to "🎯 Suggested Action Plans"
• ✅ Maintained backward compatibility with existing API endpoints
• ✅ Comprehensive test coverage with 6 test cases for various scenarios

Key Features:

• Rich JSON display showing tool and prompt details
• Clear action plans with relevance scoring
• Template strings and input variables visible for execution guidance

• ✅ PlannedStep validation working correctly
• ✅ UI provides enhanced value with comprehensive tool+prompt information

Validated Scenarios:

• Sentiment Analysis Queries: "I need sentiment analysis for customer feedback"
• Image Processing Queries: "Help me with image captions"
• Code Quality Queries: "Check code quality for security issues"
• Text Processing Queries: "Summarize long documents"
• Edge Cases: Empty queries, no results, special characters

---

✅ Task 33: Final Sprint Checks (Dependencies, Linters, Tests, CI)

Duration: 30 minutes | Status: COMPLETED

Quality Assurance Results:

Code Quality:

• ✅ Fixed linting violations in ontology.py (string literals in exceptions)
• ✅ Type checking configured to exclude duplicate modules
• ✅ All 69 tests passing (100% success rate)
• ✅ No functional regressions introduced

• ✅ All edge cases covered (empty fields, validation, error handling)

System Stability:

• ✅ Application starts and runs without errors
• ✅ API endpoints respond correctly
• ✅ Backward compatibility maintained
• ✅ No breaking changes introduced

🎉 Sprint 3 Achievements
