**Multi-agent shared brain across Claude Code/Desktop, Codex, Antigravity CLI (`agy`), Copilot, and VS Code.** Cross-session memory, self-improving skill loops, and inter-agent signaling — one local MCP server turns parallel agent instances into a coordinated multi-agent system instead of N isolated chats.

Every connected client (Claude Code, Claude Desktop, Codex CLI + desktop, Antigravity CLI, Copilot, every MCP-aware VS Code extension) shares one SQLite store, one set of threads, one user model, and one learning loop that improves the skill library autonomously over time.

The brief format is dense — structural tags, opaque IDs, ~6 KB per session-start injection. Optimized for agent consumption, not human reading.

Why

Every agent CLI starts cold. Context dies at session boundaries. Skills you taught Claude don't transfer to Codex. Threads you closed in yesterday's Antigravity chat are invisible to today's Copilot. Parallel agent instances running the same task don't know about each other and duplicate work or step on each other's writes.

thread-keeper is the substrate underneath. Three things that together make it more than a memory store:

• Collective memory — threads, notes, verbatim quotes, dialectic claims about you. Survives session, restart, CLI swap. One agent records, every other agent (any CLI) reads. The brief injected at session start gi
