What problem does it solve? Starting a release involves repetitive git mechanics — cutting the release branch, scaffolding the CHANGELOG, pushing, and opening a draft PR — plus confirming the release actually exists in the shared Marshall store. This Skill runs that whole sequence in the correct order with hard preflight checks, so a release never starts from a dirty tree, a stale default branch, or an unseeded store entry. ## Core Features & Use Cases - Store-first verification: Confirms the release is seeded in the hosted Marshall store via MCP before touching git, and refuses to proceed if the MCP server is disconnected. - Preflight guardrails: Stops on a dirty working tree, wrong branch, out-of-date default branch, or an already-existing release branch — no auto-fixing. - Git and PR mechanics: Cuts the release branch from the configured pattern, scaffolds the CHANGELOG entry with a theme, pushes, and opens a draft release PR with a wrap-status checklist. - Optional tracker linking: On explicit approval only, links the release to a GitHub milestone or an existing tracker collection (Linear Project/Cycle) via release_update. - Use Case: A maintainer says "start release v0.7.0" — the Skill verifies the release exists in the store, creates release/v0.7.0, scaffolds the CHANGELOG, and opens the draft PR that topic branches will target. ## Quick Start Say "start release v0.7.0" or run /release-open and answer the prompts for the release version and theme.
