Crossmem moves coding context between AI agents

r/ClaudeWorkflowsJul 1, 2026 · 12d ago

Crossmem reads saved from local such as Claude Code, Codex, Copilot, Devin, and OpenCode, then packages the important into Markdown. A new agent can use that package to continue the same work without a long re-explanation. The problem is common for people who switch tools because one agent is better for a task, or because a usage limit stops the current session.

Rebuilding the same context wastes time, paid API credits, and tokens. Related tools are moving in the same direction: focuses on browsing and resuming Claude Code and Codex sessions, Handoff creates a verified bridge between Claude Code sessions, and Open Memory Protocol points toward one store for Claude, ChatGPT, and Cursor-style clients. Notion-focused workflows such as notion-skills attack a nearby issue by reducing context use and repeated OAuth logins.

Some local memory tools avoid LLM summarization, which can reduce extra token cost and keep more of the workflow on the user’s machine.

Key points

  • Crossmem turns saved sessions from several into a Markdown context bundle.
  • It targets Claude Code, Codex, Copilot, Devin, and OpenCode.
  • The main benefit is avoiding repeated project explanations when switching agents or hitting usage limits.
  • , Handoff, and Open Memory Protocol show a broader push toward portable agent memory.
  • Local workflows that avoid LLM summarization can save tokens and reduce data exposure.
