What problem does it solve? Long-running, multi-phase software projects lose integrity silently — missing gate outputs, stale handoffs, outdated backlogs, and skipped review steps go unnoticed until they block work. This Skill runs as a background health monitor that detects these gaps early and surfaces them with a specific recovery path, without ever halting progress. ## Core Features & Use Cases - Signal-based health checks: Verifies phase completion through file existence checks and the backlog At a Glance section instead of reading full documents, keeping token usage low. - Lifecycle activation points: Runs at mode activation (framework version check, project state read, 21-day long-gap detection), between phases (gate integrity), during sessions (milestone lines, one hygiene reminder), and at session end (handoff currency, backlog accuracy, open issues). - Non-blocking issue surfacing: Reports one issue at a time with a concrete recovery path, logs deferred items to the session handoff, and stays silent when everything is healthy. - Use Case: When moving from design sprint to design review, the monitor detects that the deferred decisions log is missing and asks whether to produce it before the next phase starts — the user can proceed, defer, or fix it immediately. ## Quick Start Activate guided or piloted mode and let the health monitor check the handoff, backlog, and expected phase outputs before starting new work.
