[plan] Complete MaxInputSize and MaxOutputSize extraction in copilot engine

[github-actions]

Objective

Complete 2 TODO items in pkg/workflow/copilot_engine.go related to extracting MaxInputSize and MaxOutputSize from tool calls for accurate resource tracking.

Context

Current TODO comments indicate incomplete functionality:

• MaxInputSize: 0, // TODO: Extract input size from tool call parameters if available
• MaxOutputSize: 0, // TODO: Extract output size from results if available

These values are important for:

• Accurate resource tracking for Copilot tool usage
• Debugging tool configuration issues
• Monitoring and performance analysis

Approach

1. Locate TODO comments in pkg/workflow/copilot_engine.go
2. Examine tool call structure to identify where size metadata is stored:
   • Input size: Check tool call parameter structure
   • Output size: Check tool result structure
3. Implement extraction logic:

   // Extract input size with fallback to 0 if not present
   maxInputSize := extractInputSize(toolCall.Parameters)
   
   // Extract output size with fallback to 0 if not present  
   maxOutputSize := extractOutputSize(result)

4. Add error handling for missing or invalid size data
5. Document the logic with comments explaining size extraction
6. Add tests verifying size extraction with sample tool calls

Files to Modify

• pkg/workflow/copilot_engine.go (lines with TODO comments)
• pkg/workflow/copilot_engine_test.go (add tests for size extraction)

Acceptance Criteria

• MaxInputSize extraction from tool call parameters is implemented
• MaxOutputSize extraction from tool results is implemented
• Implementation includes proper error handling for missing/invalid size data
• Tests verify size extraction works correctly with sample data
• TODO comments are removed
• Code is documented with comments explaining the extraction logic
