Obsidian has quietly become the front end for AI agents. Two plugins make that work: Agent Client and its fork Agent Console. Both run Claude Code, Codex, Gemini CLI, OpenCode, and any other ACP-compatible agent inside your vault, let you @mention notes for context, and surface permission prompts before anything runs.
Same foundation (the Agent Client Protocol, the same JSON-RPC stdio transport Hermes uses over ACP). But they’ve diverged hard.
Agent Client by RAIT-09 is the ancestor. It’s the biggest and most battle-tested — 2,358 stars, 227k+ community downloads, 504k+ release downloads, Apache-2.0, TypeScript.
