prd-builder skillA

prd-builder is agent-read markdown (skill) from vmobifystudio/app-dev-team: Use to construct a complete Product Requirements Document for a mobile app from a vision file. Used primarily by the CPO agent. Triggers on requests to "write the PRD", "spec out the product", or as part of /app-plan..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

What the file says

# PRD builder

Build `docs/10-prd.md` and `docs/11-backlog.md` from `docs/00-vision.md` and `docs/01-intake.md`.

## Required sections (in order)

1. **Product summary** — 2-3 sentences.
2. **Personas** — 1-3, each with: name, goal, frustration, context-of-use.
3. **User journeys** — 3-7 prose paragraphs. Each paragraph: entry → steps → exit → success state.
4. **Feature table** —

   | ID | Name | Description | Priority | Acceptance criteria |
   |----|------|-------------|----------|---------------------|

   Use F-001, F-002, ... Priority is P0/P1/P2.

5. **User stories** — for each P0 feature, 1–5 stories:
   *As a [persona], I want to [action] so that [outcome]*
   plus Given/When/Then acceptance.

6. **Out of scope** — explicit list.

7. **Open questions** — what needs CEO or user input.

## Backlog format

`docs/11-backlog.md` — every backlog item carries both the implementation ticket ID and the PRD feature ID so the chain is traceable end-to-end:

```
# Backlog

## Sprint 1 — MVP foundation
- APP-001 [F-001] <feature> — XS/S/M/L/XL
- APP-002 [F-002] <feature> — ...

## Sprint 2 — MVP completion
- ...

## v1.1+
- ...
```
