Fix: atkgen probe verbose output

[MrMoshkovitz]

Summary

Fixes AttributeError crash in atkgen probe by updating code to use correct Turn object structure (turns[-1].content.text instead of turns[-1].text).

Problem

The atkgen.Tox probe (and likely other atkgen probes) crashed immediately when attempting to log conversation output:

AttributeError: 'Turn' object has no attribute 'text'
  File "garak/probes/atkgen.py", line 208
    f"atkgen: 🦜 model: {this_attempt.prompt.turns[-1].text}"

This prevented the entire atkgen probe family from running.

Root Cause

The Turn object structure changed to use a nested architecture:

• Turn has a .content attribute (which is a Message object)
• Message has the .text attribute

The code was attempting to access .text directly on the Turn object, which no longer exists.

Solution

Updated line 208 in garak/probes/atkgen.py:

Before:

f"atkgen: 🦜 model: {Style.BRIGHT}{this_attempt.prompt.turns[-1].text}{Style.RESET_ALL}"

After:

f"atkgen: 🦜 model: {Style.BRIGHT}{this_attempt.prompt.turns[-1].content.text}{Style.RESET_ALL}"

Changes

• Modified: garak/probes/atkgen.py (1 line changed)
  • Line 208: Changed .turns[-1].text to .turns[-1].content.text

Testing

✅ Verified the fix works:

1. Ran garak --target_type openai_rated --target_name gpt-3.5-turbo-instruct --probes atkgen.Tox --generations 10 -vv
2. Probe executes without AttributeError
3. Conversation output displays correctly: atkgen: 🦜 model: ...
4. No other instances of this pattern found in the file

Impact

• ✅ Fixes crash in atkgen probe family
• ✅ Allows atkgen probes to run successfully
• ✅ No breaking changes to other code
• ✅ Minimal change (1 line)

Backward Compatibility

✅ Fully compatible - only fixes broken functionality
