Stage 10 · Capstone

Bring everything together. You’ll build Release notes digest, a workflow that:

• starts from an HTTP trigger with a list of change titles;
• validates the input in Python;
• loops over each change, classifying it in Bash and scoring it in PowerShell;
• counts results in C#, computes a checksum in Rust, and formats Markdown in JavaScript;
• runs a Code file written in TypeScript;
• publishes through an HTTP endpoint (mock://) and an MCP tool;
• branches on whether there are breaking changes, asking an AI model for an upgrade warning only when there are.

• Prepare

  Runtimes, the project folder, a saved MCP server, and a saved model connection.

• Build it

  The complete release-digest workflow YAML, explained block by block.

• Trigger it and check the run

  Arm the HTTP trigger, POST changes with curl, and verify every block on Runs.
