# Prompt: Generate External Modules Reference Page

## Goal

Create a reference documentation page at `docs/reference/modules.md` that lists all official external BMad modules with descriptions and links.

## Source of Truth

Read `tools/cli/external-official-modules.yaml` — this is the authoritative registry of official external modules. Use the module names, codes, npm package names, and repository URLs from this file.

## Research Step

and read its README to get:
- A 1-2 sentence description of what the module does
- The key agents and workflows it provides (if listed)
- Any notable features or use cases

## Output Format

Create `docs/reference/modules.md` following the project's Reference Catalog structure (see `docs/_STYLE_GUIDE.md`):
