What problem does it solve? Teams following Spec-Driven Development (SDD) need a fast way to verify that their repository contains the required structure — .github/memory/, specs/, and per-feature spec.md, plan.md, and tasks.md files — before opening a PR or starting new work. This Skill performs a read-only audit and reports exactly what is missing, empty, or out of convention. ## Core Features & Use Cases - Structural validation: Checks .github/memory/ (constitution.md, tech.md), specs/ subdirectories, and every feature folder for required artifacts with canonical sections. - PASS/FAIL/WARN report: Emits a structured compliance report where missing files are FAIL, empty or in-progress files are WARN, and every failure includes a suggested remediation action. - Content quality metrics: Uses freshness scoring (time-based tiers plus behavior-based signals) and coverage thresholds (green/yellow/red) to flag stale or incomplete specs. - Use Case: Before merging a feature branch, run the audit to confirm spec.md, plan.md, and tasks.md exist and are non-empty, then follow the suggested actions (e.g., run /sdd-explore-tech to populate an empty tech.md). ## Quick Start Ask the assistant to validate the SDD structure of this repository and report any missing or empty spec artifacts.
