Record your application to gather performance data and debug issues. It enables users to install Replay ClI, record a session, upload and manage them.
Set up and configure Replay for recording Cypress tests with time-travel debugging.
Set up and run Playwright tests with Replay Browser to record test executions for debugging and performance analysis.
DRY and abstraction audit for duplication, reusable hooks/components, and maintainability patterns. Use when looking for refactor opportunities.
Orchestrate selected audit roles with fresh sub-agents, configurable model tier, and optional --dry-run/--debug validation. Use when running full multi-role audits.
Security audit for OWASP Top 10 risks, auth flaws, injection vectors, and secret handling. Use when validating exploitable application security issues.
This skill should be used when the user asks to "create an MCP App", "add a UI to an MCP tool", "build an interactive MCP View", "scaffold an MCP App", or needs guidance on MCP Apps SDK patterns, UI-resource registration, MCP App lifecycle, or host integration. Provides comprehensive guidance for building MCP Apps with interactive UIs.
