Prompt: Plan Cross-Repository Feature

Use this prompt in anuva-main-video-creator when a product feature needs coordinated planning across implementation repositories.

Read the Anuva Video Creator product docs in this repository.
Follow the product-main workflow from anuva-engineering-handbook.

Plan the following cross-repository feature:

Feature name:
Feature goal:
User outcome:
Known constraints:

Create or update a product change folder:

docs/changes/<YYYY-MM-DD-feature-name>/

Include:
- Product intent
- Non-goals
- Affected capabilities
- Affected repositories
- Repository impact summary
- Cross-repository dependencies
- Product acceptance criteria
- GitHub issue handoff requirements
- GitHub Project field assumptions
- Documentation updates required
- Product ADR recommendation, if needed
- Open questions

Create drafts for:
- FeatureBrief.md
- RepositoryImpact.md
- HandoffPrompts.md
- tasks.yml
- GitHubTasks.md placeholder
- Progress.md placeholder
- ReviewChecklist.md

Do not add implementation code. Do not create GitHub issues until the product
docs are reviewed.
