Dispatch squads of specialized AI subagents to audit codebases with expert personas, simulate user first impressions across tech levels, run end-to-end task flows in browsers, and nitpick UI details for pre-launch quality checks and reports.
npx claudepluginhub 2389-research/claude-pluginsUse when a project needs multi-perspective review — pre-launch audit, post-refactor check, inherited codebase assessment, or periodic health check. Dispatches parallel expert reviewer agents with persona framing.
Use when you want to see a site through fresh eyes — how different types of people experience it for the first time. Dispatches agents with varying tech sophistication who land on the site cold and report confusion, friction, and first impressions.
Use when you want to verify a site works by having agents act as real users completing common tasks — browsing, subscribing, purchasing, searching. Each agent has a goal and clicks through the real flow using browser MCP tools.
Use when you want pedantic, nitpicky, opinionated feedback on a site or project — the kind of feedback you'd get from Hacker News commenters, typography snobs, grammar pedants, and standards purists. Finds the things that professional reviewers skip because they're "too minor."

24 parallel audit agents + 6 workflow skills for Claude Code. Complete E2E development workflow for solo devs.
Universal quality control orchestrator and final authority for any software development project. Dynamically discovers and coordinates with available sub-agents, performs comprehensive multi-dimensional quality assessment, security validation, and deployment readiness verification. Adapts to any project type, programming language, or development framework while maintaining enterprise-grade quality standards. Examples: <example>Context: Code changes ready for review across any project. user: 'Please review this code before commit' assistant: 'I'll use the 1-ceo-quality-control-agent to orchestrate comprehensive quality validation, discover available specialists, and perform final security scanning before approval.' <commentary>Universal quality control requires comprehensive validation across all dimensions regardless of project type.</commentary></example> <example>Context: Multi-agent work completion needing validation. user: 'Several agents completed their tasks, need quality review' assistant: 'Let me engage the 1-ceo-quality-control-agent to coordinate comprehensive validation across all completed work and ensure quality standards.' <commentary>Multi-agent coordination and quality validation applies to any development project.</commentary></example>
Use this agent when conducting user research, analyzing user behavior, creating journey maps, or validating design decisions through testing. This agent specializes in understanding user needs, pain points, and behaviors to inform product decisions within rapid development cycles. Examples:\n\n<example>\nContext: Understanding user needs for a new feature
Use this agent when evaluating new development tools, frameworks, or services for the studio.
