I built a manifest standard for agent-callable CLI tools – 93.6% routing accuracy, zero fine-tuning

I've been building agentic systems and kept running into the same problem: agents either stuff entire tool docs into every prompt, or hallucinate the wrong tool entirely. CLI tools are 10–32× cheaper than MCP and nearly 100% reliable — but there's no standard way for agents to discover and invoke them. So I built CLIbrary: an open standard where each CLI tool has a manifest.json with intent_triggers — natural language phrases describing when to use it. A routing layer does nearest-neighbor searc
