Turn HAR Files, Claude Code, Copilot CLI, and Codex CLI Logs into ATIF (github.com)

A new command-line tool, "atifact," has been released to convert various agent logs—including HAR files, Claude Code logs, Copilot CLI logs, and Codex CLI logs—into standardized ATIF v1.7 trajectory JSON format. This tool simplifies the log conversion process by requiring zero dependencies and can be invoked with straightforward commands like "atifact session.har" or "atifact claude-log.jsonl." Once installed, AI coding agents can extract these trajectories with ease, making debugging, visualization, fine-tuning, and reinforcement learning pipelines more efficient. The significance of this development lies in its potential to streamline workflows within the AI/ML community by enabling developers to easily analyze and refine agent interactions. The generated ATIF trajectories contain detailed metrics, including user messages, agent responses, tool calls, and aggregated totals, all preserved in a structured format with timestamps. Notably, it supports embedding subagent trajectories for tools such as Copilot and Codex, enhancing the granularity of data analysis. This advancement not only facilitates better debugging practices but also opens up new avenues for optimizing AI training and deployment strategies.
