Antibody
Antibody is a plugin and tool layer that shares error fixes across running coding agent fleets.
Antibody sits underneath coding agent tools to watch for errors and move fixes between running agents. When a tool call fails, the layer normalizes the message into a fingerprint and shares the recorded fix with other sessions in the repository. It supports Claude Code, Gemini CLI, Codex CLI, and any agent that speaks MCP. Shared memory lives in the repository common git directory without needing a server or database. It includes live terminal monitoring tools, event logs, and human-editable memory files.
