agent-session

agent-session normalizes local AI coding-agent transcripts into one portable Rust session model. It discovers Claude Code, Codex, and Gemini CLI sessions, parses tokens/tools/files/prompts into a common IR, and includes a matcher for linking live process trees back to agent sessions.

let sessions = agent_session::SessionCache::new()
    .discover_cached(25, std::time::Duration::from_secs(2));

Scope

• Transcript/session discovery and parsing for local coding-agent logs.
• Token, tool, file, prompt, cwd, and timing normalization.
• Process-tree to session matching, including PID-to-session lookup.

agent-session intentionally does not export OpenTelemetry directly. Applications such as AgentSight can map the IR to SQLite, OTEL, reports, or any other telemetry backend they use.

Publishing

The crate is published from the AgentSight release workflow before agentsight itself, then agentsight depends on that published version. Publishing to crates.io also makes the crate available to docs.rs and discoverable by the unofficial lib.rs index.
