What problem does it solve? Keeping a copied-into-.claude/ orc pack installation current is error-prone when the install is several releases behind, since renames, removals, and migration steps accumulate across versions. This Skill automates the full upgrade path in one pass, converging the install on the latest released kit without manual diffing. ## Core Features & Use Cases - Version and provenance detection: Reads the local pack version marker and provenance file to establish the installed version, source repo, and install root. - Cumulative migration map: Fetches the latest GitHub release via gh, assembles every in-range changelog section into an ordered update map, and falls back to a git diff when release notes are thin. - Subagent-driven convergence: Dispatches the orc-updater subagent (Opus 4.8) to converge the install on the fetched kit, then verifies file parity, frontmatter integrity, and provenance re-recording. - Use Case: You installed orc-pack 1.1.0 months ago and the latest release is 1.4.0. Run the update and the Skill applies all intermediate migrations, refreshes every pack file, preserves your local edits, and reports the full transition. ## Quick Start Ask the assistant to update the orc pack to the latest release and it will detect your installed version, fetch the newest kit, and converge the installation.
