Agent Sessions, created by open-source developer Alex D. (jazzyalex), is a native macOS viewer and harness for indexing, searching, and inspecting interaction logs across CLI coding agents. Instead of running prompts directly, it functions as an aggregator that parses session history, tool execution records, and agent artifacts generated by various terminal assistants. In daily use, the application discovers session stores created by supported coding agents such as Claude Code, Codex hooks, Antigravity, and other CLI tools. It provides a searchable desktop interface with configurable preferences to filter sessions by agent kind, hide zero-message empty runs, and audit multi-turn conversation traces alongside tool invocations. Agent Sessions distinguishes itself by focusing on post-execution observability and format verification across disparate agent frameworks. It maintains continuous format-checking tooling and stage fixtures to handle evolving schema changes across CLI agent ecosystems. The project is open source and hosted on GitHub, with ongoing maintenance targeting macOS environments and support for over a dozen agent discovery paths.
