What problem does it solve? Managing a Claude Code plugin marketplace involves error-prone operational work: reviewing skill PRs, landing merges correctly, promoting releases to machines, rolling back bad builds, and keeping versions, frontmatter, and documentation truthful. This Skill encodes that operational discipline so the marketplace is run consistently rather than re-derived each session. ## Core Features & Use Cases - Skill change review and landing: Runs the review-and-merge loop with content-verified squash merges, one ticket per PR, and a strict rule that a session never lands its own work. - Promotion and rollback: Executes the deliberate promotion of merges to the release ref and force-move rollback of bad builds, with verification that a real install received the change. - Roster and version hygiene: Enforces frontmatter checks, semver bump discipline (patch/minor/major as claims about the change), pin management, and keeps MANUAL.md accurate in the same PR as any change. - Use Case: A skill PR lands on main and needs to reach every team machine. This seat runs the promotion one-liner, adds the changelog row to MANUAL.md, and verifies a real install pulled the new version before declaring it shipped. ## Quick Start Ask the agent to review and land this skill PR, then promote lia-tools to release and verify the install.
