Run a phased performance investigation workflow that establishes baselines, maps code paths, profiles hotspots with flame graphs, generates and tests hypotheses via benchmarks, logs evidence, and synthesizes recommendations with decisions for Node/JS, Python, Rust, Go, Java projects.
npx claudepluginhub composiohq/awesome-claude-plugins --plugin perfSynthesize perf findings into evidence-backed recommendations and decisions.
Map likely code paths for perf scenarios before profiling.
Append structured investigation notes with exact user quotes and rationale.
Coordinate /perf investigations across all phases, enforcing non-negotiable perf rules.
Generate top performance hypotheses after reviewing git history and current metrics.
Use when synthesizing perf findings into evidence-backed recommendations and decisions.
Use when managing perf baselines, consolidating results, or comparing versions. Ensures one baseline JSON per version.
Use when running performance benchmarks, establishing baselines, or validating regressions with sequential runs. Enforces 60s minimum runs (30s only for binary search) and no parallel benchmarks.
Use when mapping code paths, entrypoints, and likely hot files before profiling.
Use when appending structured perf investigation notes and evidence.

Performance analysis, profiling, and optimization recommendations
Use this agent for comprehensive performance testing, profiling, and optimization recommendations. This agent specializes in measuring speed, identifying bottlenecks, and providing actionable optimization strategies for applications. Examples:\n\n<example>\nContext: Application speed testing
Profile application performance with CPU, memory, and execution time analysis
CodSpeed plugin for Claude Code helping with performance measurement and optimization.
Analyze and optimize code performance
Performance engineering agents providing expertise in profiling, optimization, and scalability
Creates git commits using conventional commit format with appropriate emojis, following project standards and creating descriptive messages that explain the purpose of changes.
Create distinctive, production-grade frontend interfaces with high design quality. Generates creative, polished code that avoids generic AI aesthetics.
Use this agent when designing APIs, building server-side logic, implementing databases, or architecting scalable backend systems. This agent specializes in creating robust, secure, and performant backend services. Examples:\n\n<example>\nContext: Designing a new API\nuser: "We need an API for our social sharing feature"\nassistant: "I'll design a RESTful API with proper authentication and rate limiting. Let me use the backend-architect agent to create a scalable backend architecture."\n<commentary>\nAPI design requires careful consideration of security, scalability, and maintainability.\n</commentary>\n</example>\n\n<example>\nContext: Database design and optimization\nuser: "Our queries are getting slow as we scale"\nassistant: "Database performance is critical at scale. I'll use the backend-architect agent to optimize queries and implement proper indexing strategies."\n<commentary>\nDatabase optimization requires deep understanding of query patterns and indexing strategies.\n</commentary>\n</example>\n\n<example>\nContext: Implementing authentication system\nuser: "Add OAuth2 login with Google and GitHub"\nassistant: "I'll implement secure OAuth2 authentication. Let me use the backend-architect agent to ensure proper token handling and security measures."\n<commentary>\nAuthentication systems require careful security considerations and proper implementation.\n</commentary>\n</example>
Guide for creating high-quality MCP (Model Context Protocol) servers that enable LLMs to interact with external services through well-designed tools.
Streamlines pull request creation by handling the entire workflow: creating a new branch, committing changes, formatting modified files with Biome, and submitting the PR.
