 "summary": "Use Pydantic AI Harness's Coder capability to get file access, shell, repo context and sub-agents in one agent.",
 "who": "An engineer who wants a coding agent they fully control, with their choice of models.",
 "problem": "Off-the-shelf coding agents are hard to customise and tie you to one vendor.",
 "outcome": "A chat-in-the-terminal coding agent built from composable capabilities you can swap or extend.",
 "steps": [
  "Install with `uv add pydantic-ai \"pydantic-ai-harness[coder]\"`",
  "Create an Agent with capabilities Coder(), and optionally WebSearch() and an Advisor on a second model, as in the README",
  "Call agent.to_cli_sync() and run the file to chat with it",
  "Or try it without code using the README's uvx command that runs the exported coder_agent with clai",
  "Replace Coder() with its building blocks such as FileSystem, Shell and RepoContext to customise it"
 ],
 "agent_prompt": "Using pydantic/pydantic-ai and pydantic-ai-harness[coder], create a terminal coding agent on <model> with Coder() and WebSearch(), restrict the shell to an allowlist, and run it on this repo to <task>.",
