v0.5.0

What's New

Detailed Execution Logs (datagen agents logs)

You can now drill into a specific execution to see the full step-by-step logs -- what the agent did, what tools it called, what errors it hit.

New flags:

Flag	Description
--execution <id>	Show detailed logs for a specific execution
--session <id>	Look up by session ID
--level <level>	Filter by log level (INFO, WARNING, ERROR)
--transcript	Show full Claude conversation transcript

Examples:

# Detailed logs for an execution
datagen agents logs <agent-id> --execution <execution-id>

# Look up by session ID
datagen agents logs <agent-id> --session <session-id>

# Errors only
datagen agents logs <agent-id> --execution <id> --level ERROR

# Full Claude conversation transcript
datagen agents logs <agent-id> --execution <id> --transcript

Log Output Improvements

• Duplicate log entries are deduplicated (no more 3x repeated messages)
• JSON log messages are parsed into readable format (assistant thinking, tool calls, system init)
• Binary signatures and noise stripped from output
• Long content truncated with ... for readability
