What problem does it solve? Product specs often reach Engineering, Design, and QA with missing sections, vague language like "fast" or "user-friendly", and incomplete user stories, causing misalignment and rework during the build phase. ## Core Features & Use Cases - Section Completeness Checks: Verifies required sections such as Objective, Scope, Personas, Functional Requirements, User Stories, Non-Functional Requirements, and Success Metrics exist and are not placeholder-only. - Vague Language Detection: Flags unquantified adjectives and verbs ("fast", "handle", "improve") and demands concrete metrics, dates, and quantities. - Story Coverage & ID Validation: Confirms every functionality block covers happy, edge, error, and empty paths, and that requirement IDs are unique and sequential. - Use Case: Before sending a Smart Follow-Up feature spec to stakeholders, run the review to get a scorecard grading each check as PASS, FAIL, or WARN, plus an ordered fix list. ## Quick Start Review the spec at 08-product-features/smart-follow-up-prd.md and give me a pass/fail scorecard with fix suggestions.
