Write a Functional Requirements Document. Use when the user says "write an FRD", "functional requirements", "system requirements", "SRS", "what should the system do", "document the functional specs", "software requirements specification", "detailed requirements for engineering", "functional spec" - even if they don't explicitly say "FRD".
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
## Reference Files - `references/requirements-attributes.md` - Standard attributes for each requirement (ID, type, priority, status, source, rationale, fit criterion, dependencies). Read this in Step 3 when writing individual requirements. ## Overview Based on **Software Requirements** by Karl Wiegers & Joy Beatty - the modernized IEEE 830 SRS structure that organizes functional requirements by feature or use case, not by system component. Also draws on **User Stories Applied** by Mike Cohn for agile-format FRDs using the INVEST criteria (Independent, Negotiable, Valuable, Estimable, Small, Testable). The key insight from Wiegers: every functional requirement must have a rationale (why it exists) and a fit criterion (how you know it's satisfied). Requirements without these two attributes are wishes, not requirements. ## Workflow ### Step 1: Define the system context Before writing requirements, establish what the system is: ``` SYSTEM NAME: [name] PURPOSE: [one sentence] USERS: [user roles and their primary goals] ADJACENT SYSTEMS: [systems this integrates with] SCOPE REFERENCE: [link to BRD or scope document] ``` ### Step 2: Organize by functional area …

How to install
mdr add qa-aman/claude-skills/frd-writer@sha256:56227c0fa71fc5adThe line at the top of this page pins the label git:20260323.771ca1c, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
