Routing

This skill auto-selects the correct workflow based on whether a changelog already exists.

Step 1: Detect Existing Changelog

Check for CHANGELOG.md in the project root (case-insensitive: also check changelog.md, Changelog.md).

Step 2: Route

• File exists — Follow the changelog:update workflow.
• No file — Follow the changelog:create workflow.
