Build working prototypes from PRDs with mock data and stubbed integrations. Use when user has a PRD, spec, or feature description and wants a clickable demo to validate flows before full implementation. Triggers: build a prototype, functional prototype, make a demo, implement this PRD, prototype this spec, make it clickable.
Builds working prototypes from PRDs with mock data and stubbed integrations for clickable demos.

references/next-steps-template.mdBuild working prototypes from PRDs with realistic mock data and stubbed dependencies.
Extract:
Create a dedicated mocks directory with:
Stub patterns by dependency type:
| Dependency | Stub Pattern |
|---|---|
| Database | Return filtered/sorted mock data |
| Auth | Return mock user, always succeed |
| File upload | Store in memory/localStorage |
| Payment | Return success with fake transaction ID |
| External API | Return realistic mock response |
| Email/SMS | Console.log the message |
| Search | Filter mock data client-side |
For each screen:
After prototype is complete, ask user: "Would you like me to generate an integration guide documenting how to replace stubs with real implementations?"
If yes, create docs/integration-guide.md following references/integration-guide-template.md.
This skill should be used when the user asks to "create a slash command", "add a command", "write a custom command", "define command arguments", "use command frontmatter", "organize commands", "create command with file references", "interactive command", "use AskUserQuestion in command", or needs guidance on slash command structure, YAML frontmatter fields, dynamic arguments, bash execution in commands, user interaction patterns, or command development best practices for Claude Code.
This skill should be used when the user asks to "create an agent", "add an agent", "write a subagent", "agent frontmatter", "when to use description", "agent examples", "agent tools", "agent colors", "autonomous agent", or needs guidance on agent structure, system prompts, triggering conditions, or agent development best practices for Claude Code plugins.
This skill should be used when the user asks to "create a hook", "add a PreToolUse/PostToolUse/Stop hook", "validate tool use", "implement prompt-based hooks", "use ${CLAUDE_PLUGIN_ROOT}", "set up event-driven automation", "block dangerous commands", or mentions hook events (PreToolUse, PostToolUse, Stop, SubagentStop, SessionStart, SessionEnd, UserPromptSubmit, PreCompact, Notification). Provides comprehensive guidance for creating and implementing Claude Code plugin hooks with focus on advanced prompt-based hooks API.
