- Complete metadata section
- Success metrics tables
- Architecture diagrams
- Detailed API design sections
- Security threat analysis
- Monitoring & observability
- Risk assessment matrix
- Rollout and rollback plans
- Dependencies tracking

## Best Practices
**Do:**
- Include measurable acceptance criteria
- Add architecture diagrams
- Define explicit API contracts
- Quantify performance targets
- Document risks and mitigations
- Get stakeholder review before implementation
- Include security considerations
- Define rollback procedures
**Don't:**
- Use vague requirements ("fast", "scalable")
- Skip non-functional requirements
- Ignore security considerations
- Leave alternatives unexplored
- Omit testing strategy
- Forget dependencies and risks
Creating algorithmic art using p5.js with seeded randomness and interactive parameter exploration. Use this when users request creating art using code, generative art, algorithmic art, flow fields, or particle systems. Create original algorithmic art rather than copying existing artists' work to avoid copyright violations.
Applies Anthropic's official brand colors and typography to any sort of artifact that may benefit from having Anthropic's look-and-feel. Use it when brand colors or style guidelines, visual formatting, or company design standards apply.
Create beautiful visual art in .png and .pdf documents using design philosophy. You should use this skill when the user asks to create a poster, piece of art, design, or other static piece. Create original visual designs, never copying existing artists' work to avoid copyright violations.
