[BUG] The debugger currently not showing tool calls

[edenreich]

Summary

When using the debugger to fetch the task conversation history I only see the user -> assistant messages.

Steps to Reproduce

1. Run docker run --rm --net host ghcr.io/inference-gateway/a2a-debugger:latest --server-url http://localhost:8080 tasks get <Task ID>
2. See:

docker run --rm --net host ghcr.io/inference-gateway/a2a-debugger:latest --server-url http://localhost:8080 tasks get 5e291312-74d5-49f5-a76d-0e6ae77060bd

Fixed tool call display issue ✅

I found and fixed the bug that was preventing tool calls from being displayed in the debugger output.

Todo List:

• Read repository setup instructions and understand codebase structure
• Examine current task display logic in CLI code
• Identify where message parts are processed and displayed
• Find the bug causing tool calls to be filtered out or not handled
• Implement fix to properly display tool calls
• Test changes and ensure they work correctly
• Follow development workflow (generate, lint, build)
• Commit changes and create pull request

Root Cause:

The CLI was only displaying message parts with "text" content, completely ignoring other part types like "data" parts (which contain tool calls) and "file" parts.

Before:

// Only showed text parts, ignored everything else
if text, exists := partMap["text"]; exists {
    fmt.Printf("     Part %d: %v\n", j+1, text)
}

Solution:

Added a comprehensive displayPart() helper function that properly handles all A2A message part types according to the protocol:

• TextPart (kind: "text") → Shows text content
• DataPart (kind: "data") → Shows structured data with JSON formatting (tool calls!)
• FilePart (kind: "file") → Shows file info (name, type, URI/size)
• Unknown parts → Shows available content with fallback handling

Changes Made:

1. ✅ Added displayPart() function - Comprehensive part display logic with proper formatting
2. ✅ Updated getTaskCmd - Both current message and history now show all part types
3. ✅ Updated historyCmd - All conversation history now shows all part types
4. ✅ Followed development workflow - task generate, task lint, task build all passed
5. ✅ Committed changes - Clean commit with descriptive message

What's Fixed:

• Tool calls in DataParts will now be visible with JSON formatting
• File attachments will show file information
• Any other structured data will be properly displayed
• Backward compatibility - Text parts still work exactly as before

The debugger will now show ALL message content, not just text, making it much more useful for debugging A2A conversations with tool calls and other structured data.
