Portable project memory across Claude Code, Codex and OpenCode, plus token accounting measured from harness transcripts. Local file I/O, no API calls, no telemetry.

Turns corrections into Preferences, Project-specific skills, and Shared skills for Claude Code, Codex, and OpenCode.

Letta's July 2026 library that normalizes native session transcripts from 15+ harnesses (Claude Code, Codex, Cursor, OpenCode, Pi, Gemini CLI, OpenHands, and more) into one validated, model-ready record format. Fills a real infrastructure gap — every runtime logs the same concepts (messages, reasoning, tool calls, results) in incompatible formats — and is explicitly designed for *agent* consumptio

One source of truth for AI coding rules across every IDE. Author rules, agents, and skills once in plain markdown, and the engine routes them into each tool's native format (Claude Code, Cursor, Copilot, Codex, Pi, OpenCode, AGENTS.md) with no duplication or drift. Zero dependencies, bash + awk, MIT
