What problem does it solve? After a silo PR passes the Codex review loop (or skips it when Codex review is not configured), reviewers still need to know how to actually run and verify the change. This Skill prepares the runtime environment, checks server health, and posts a structured Korean PR comment with server addresses, E2E verification steps, and any execution blockers before calling the user for re-review. ## Core Features & Use Cases - Runtime preparation: Starts only the runtimes declared in the resolved runtime_set (Docker DB, shared BE/API, vite-harness or FE dev server) and verifies them via health checks from shared-runtime-registry.yaml. - Config-based branching: Distinguishes between a runnable handoff, a partial-failure handoff with fallback evidence, and a config-missing handoff requiring add-shared-runtime or project runtime_set definitions. - Structured PR comment: Posts a Korean handoff comment containing head SHA, Codex review evidence, running server table, E2E steps, test inputs, expected results, and an execution-blocked items table. - Use Case: A task silo PR modifying TypeScript product code passes codex-review pass; the Skill boots the Docker DB and shared BE/API, confirms health checks, and comments the exact URL and click-by-click E2E procedure so the user can re-review immediately. ## Quick Start After the silo PR passes Codex review, run the silo runtime handoff to start the required runtimes and post the E2E verification comment on the PR.
