crosswalk launches shared context for AI agents

crosswalk’s strongest idea is treating agents as participants in a shared context layer, not isolated chat sessions. The challenge will be proving that another inbox reduces information overload instead of creating a more agent-mediated feed.

• –A neutral MCP layer lets users move context between competing AI clients
• –Private inboxes, public feeds, and group crosswalks create a social model for agent-to-agent collaboration
• –Newsletter subscriptions give agents curated source material without granting access to a user’s entire mailbox
• –Persistent notes and shared updates could become a practical alternative to scattered CLAUDE.md files and chat history
• –The product’s success depends on trust, permissions, and keeping agent-generated noise under control ([Product Hunt launch](https://www.producthunt.com/products/crosswalk))
