Session log parsing for AI coding agents.

Parses session logs from various AI coding agents:

• Claude Code (JSONL)
• Gemini CLI (JSON)
• OpenAI Codex CLI (JSONL)
• Normalize Agent (JSONL)

Architecture

This crate separates parsing from analysis:

• Parsing: LogFormat::parse() converts format-specific logs into a unified Session type
• Analysis: Consumers compute their own metrics from Session data

Each log format implements the LogFormat trait for format detection and parsing.

Example

use normalize_chat_sessions::{parse_session, Session};

let session = parse_session("~/.claude/projects/foo/session.jsonl")?;
for turn in &session.turns {
    for msg in &turn.messages {
        println!("{}: {} blocks", msg.role, msg.content.len());
    }
}
