What problem does it solve? Teams often judge sprint health by velocity alone, missing architectural decay, growing tech debt, and stale backlogs. This Skill runs a periodic system audit that produces an actionable report: top risks, a tech debt score, recommended new issues, and backlog cleanup suggestions. ## Core Features & Use Cases - Architecture Review: Evaluates active quality dimensions (Reliability, Data Integrity, Security, Performance, Observability, Maintainability, plus optional add-ons) against ARCHITECTURE_DESIGN.md and SYSTEM_ARCHITECTURE.md. - Tech Debt & Backlog Hygiene: Detects code duplication, hardcoded values, orphaned issues, missing dependencies, and obsolete tickets. - Learning Loop (L1/L2/L3): Mandatory retrospective step that writes lessons-learned entries to a journal, from a simple markdown file up to a SQLite-backed metrics store. - Use Case: Run a quarterly health check that reads your backlog, architecture docs, config, and git log, then outputs a summary report plus ready-to-create Linear tickets for identified tech debt. ## Quick Start Ask the assistant to run a sprint review of the current project, auditing architecture, tech debt, and backlog hygiene.
