 "title": "Add a business tool to the agent as a plugin",
 "page_title": "How to add a business tool to the agent as a plugin with Agnes Harness",
 "summary": "Register a customer-specific tool as a backend plugin so the agent can call it.",
 "who": "A solutions engineer whose customer needs the agent to query an internal order or knowledge system.",
 "problem": "Writing customer systems directly into the agent means forking it for every deployment.",
 "outcome": "A backend plugin registers a tool the agent can call, and each call keeps its inputs and structured output.",
 "steps": [
  "Clone the Agnes Harness repository and open its root directory.",
  "Run `pnpm install --frozen-lockfile`.",
  "Run `pnpm --filter @agnes/cli build:local`.",
  "Read the backend plugin guide at docs/develop/backend.md and start from the demo_text_stats example.",
  "Run `node packages/cli/dist/local/agnes.mjs serve`, open the printed loopback URL, and call your tool in a task."
 ],
 "agent_prompt": "Work in the agnes-harness repository at <repo path>. Follow docs/develop/backend.md to add a backend plugin that exposes a tool named <tool name> for <business system>. Confirm the tool appears in a task and returns structured output. Report the files you changed.",
 "agents": [
  "any"
 ],
 "difficulty": "Intermediate",
 "time": "1 hour",
 "basis": "readme",
 "caveat": "AGH is a pre-alpha developer preview, and ordinary backend plugins run as trusted in-process code, so review plugin code before enabling it.",
