Her · हेर — a detective for your Claude Code sessions

Her, a tool named after the Marathi word for "detective," is designed to analyze and decipher the intricate details of Claude Code sessions by reading the .jsonl files generated during these sessions. The tool processes these files to provide a clear, English-language summary of session activities, identifying potential issues and suggesting improvements based on best practices from Anthropic and the community. Her operates without relying on third-party AI APIs, ensuring privacy by using a deterministic evaluation engine and the Nemotron-Mini-4B-Instruct model for generating suggestions. It highlights key activities like tool deployments and production changes, offering users insight into the usage of various tools and subagents. The tool was initially developed over a weekend to visualize query costs and has since evolved to include an executive report and a comprehensive database for identifying command-line tools used in sessions. Her is accessible on Hugging Face, running on its own GPU to maintain user privacy.
