A hands-on walkthrough of building a release notes generator using the Cline SDK, an open-source TypeScript framework for embedding AI agent runtimes into custom tools and scripts. The tutorial covers project setup, defining a custom `get_recent_commits` tool, configuring an Agent with OpenAI, and wiring a system prompt to produce structured markdown output. Key insight: the Cline SDK separates the agent runtime from the VS Code extension, making it embeddable in CI jobs, internal tools, and scripts. The same pattern can be reused for PR summaries, changelog drafting, and other SDLC automation tasks.
