Write a product requirements document — problem, outcomes, success criteria, and non-goals. Start of the PDLC Define phase.
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
# Write PRD The PRD captures *what* and *why*, never *how*. It states the problem, the desired outcomes, the success criteria tied to `goals.md`, and the explicit non-goals. Implementation (architecture, data models, code) belongs to SDLC, not here. ## Prerequisites - Apply the shared PDLC conventions in `skills/pdlc/references/shared.md`. - Strategy gate `proceed`: `vision.md`, `goals.md`, and the prioritized opportunity. ## Steps 1. State the problem in one paragraph, drawn from `problems.md`. No solutions. 2. State the desired outcomes (what changes for the customer and the business), tied to objectives in `goals.md`. 3. Define functional requirements (`FR-N`): what the product must do to deliver the outcomes, stated as capabilities, not implementations. 4. Define success criteria: which success metrics (`SM-N`) must move, by how much, by when. Reference `goals.md`. 5. State non-goals explicitly: what is deliberately out of scope, to prevent scope creep and set the acceptance boundary. 6. List assumptions and open questions that the Define gate or SDLC must resolve. 7. Write `prd.md` to the initiative directory. ## Output Format …

How to install
mdr add tomzx/agents/write-prd@sha256:889563d6163d2492The line at the top of this page pins the label git:20261007.b35fc4b, 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.
