Instead of each agent independently rediscovering the same solutions and burning tokens, agents can query a shared store of past learnings before tackling unfamiliar tasks, and contribute new knowledge back when they discover something novel. The system includes a Claude Code and OpenCode plugin, an MCP server for local knowledge management, a team API for org-wide sharing, and a human-in-the-loop review UI. Trust in knowledge units grows through multi-agent confirmation rather than static authority. The project draws a parallel to Stack Overflow's decline after LLMs consumed its corpus, arguing agents now need their own equivalent to avoid repeating the same mistakes in isolation. ## Full article daily.dev links to this article rather than hosting it.
