description	Add reference material to a project — use when: add a reference, save inspiration, attach examples, link this site as reference, drop in a moodboard

Adds reference material (screenshots, wireframes, brand guidelines, competitor examples, design specs, URLs) to a project's `references/` directory for use by all downstream agents.

References are loaded by design, build, and research commands and passed to their agents as additional context.

Add reference material to a project for downstream agents to consume.

Input: User-provided files, URLs, or descriptions Output: {project}/references/ with organized reference files + references/INDEX.md

- Always use `AskUserQuestion` for user interaction — never prompt via plain text - One decision per question — never batch multiple questions in a single message ## Step 0: Resolve project

Scan .design/projects/ for project directories. If only one project exists, use it. If multiple, ask the user which project to work on.

Set PROJECT_PATH = .design/projects/{project}

Step 1: Ensure references directory

mkdir -p {PROJECT_PATH}/references

Step 2: Determine reference type

If the user provided a file path, URL, or description in the skill invocation, use that. Otherwise, ask:

Use AskUserQuestion with options:

• Screenshot or image — "Add a screenshot, mockup, or wireframe"
• URL — "Save a webpage or design reference from a URL"
• Competitor example — "Document a competitor's approach"
• Brand guidelines — "Add existing brand guidelines or style guide"
• Design spec — "Add a design specification or requirements doc"
• Other — "Add any other reference material"

Step 3: Process reference

For file paths (images, PDFs, documents):

1. Verify the file exists
2. Copy to {PROJECT_PATH}/references/ with a descriptive name
3. If it's an image, read it to generate a text description
4. Write a companion .md file with metadata (source, date added, description, relevant screens/phases)

For URLs:

1. Fetch the URL content
2. Write a summary to {PROJECT_PATH}/references/url-{kebab-name}.md with:
   • Source URL
   • Date captured
   • Key takeaways
   • Relevant screens/phases
   • Screenshots or key quotes

For descriptions/notes:

1. Write to {PROJECT_PATH}/references/note-{kebab-name}.md with:
   • Description
   • Date added
   • Relevant screens/phases

Step 4: Update index

Write or update {PROJECT_PATH}/references/INDEX.md:

# Project References
> Project: {name} | Last updated: {DATE}

## References

| # | Reference | Type | File | Added | Relevant To |
|---|-----------|------|------|-------|-------------|
| 1 | {description} | {screenshot/url/note/guideline} | [{filename}](./{filename}) | {DATE} | {screens/phases} |

Step 5: Confirm

Display what was added and which phases will use it:

• Research agents scan references for competitive context
• Design agents use references as visual/functional inspiration
• Build agents reference implementation examples
• Review agents check against reference expectations

"Reference added. It will be available to all downstream phases."
