## About agentkit.md

agentkit.md is a public, agent-ready registry of plugin cards: structured, AI-generated profiles of agent-harness plugins (what a plugin does, how to install it, which platforms and agents it supports), served over a keyless REST API, an MCP server, and a searchable catalog.

Today the registry covers the **Herdr** agent harness (https://herdr.dev). Every card is an AI-generated structured profile built from a plugin's public README and manifest data: what the plugin does, how to install it, which platforms and agents it supports, and the evidence for each generated claim. Cards are human-reviewable by design — each field links back to quoted source material, and a quality tier (thin / ok / solid) says how confident the generation was.

The mission of agentkit.md is to make agent-harness plugins discoverable the way agents actually read: structured, machine-fetchable, and honest about uncertainty. Agents can search the catalog over a keyless REST API, page through every card, or use the MCP server at https://agentkit.md/mcp. More harnesses beyond Herdr are planned.
