## What foundry-agent-starter-kit does, in the publisher's words

Build, test, and deploy Microsoft Foundry agents from Python repos.

This package collects the reusable Copilot guidance for Foundry agents. It is named for the user job, not for the SDK. Castia remains the Python package underneath the flow.

## Skills

- castia-lifecycle: Use the castia Python SDK to build a Foundry agent, attach native MCP tools, run offline checks, evaluate or optimize an agent, and prepare separately authorized RFT work. Covers canonical imports, uv extras, credentials, evidence boundaries, and free versus billable operations. Start with the cons…
- castia-optimizer: Use Castia's Foundry Agent Optimizer lifecycle, canonical.agent_configs baselines, native MCP toolbox guidance, and optimize run/status/cancel/apply commands. Covers offline previews, candidate resolution, live evidence limits, and the separate azd deployment handoff.
- foundry-story-flow: Build and verify the local to Foundry to Teams story flow for a Castia-based Microsoft Foundry hosted agent, with approval gates for live work.
