What problem does it solve? Opening a pull request without checking branch hygiene, scope, and verification leads to noisy reviews, leaked secrets, and missing migrations or documentation. This Skill runs a structured readiness audit before a PR is created. ## Core Features & Use Cases - Git Hygiene Inspection: Reviews git status, staged and unstaged diffs, untracked files, and blocks committing secrets like .env files, tokens, or private keys. - Scope and Follow-Up Checks: Flags oversized branches for splitting and identifies required migrations, docs updates, and companion vellum-assistant-platform PRs. - Linear and PR Conventions: Enforces Linear issue IDs in branches and PR bodies (Closes JARVIS-123 vs Part of JARVIS-123) and provides a compact Summary/Test Plan/Risk PR template. - Use Case: Before opening a PR for a multi-package feature, run this Skill to confirm tests and typechecks ran, unrelated changes are excluded, and the PR body links the correct Linear issue. ## Quick Start Ask the assistant to check whether the current branch is ready for a pull request using the vellum-pr-readiness checklist.
