By ComposioHQ
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.
Synthesize 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.

Streamlines pull request creation by handling the entire workflow: creating a new branch, committing changes, formatting modified files with Biome, and submitting the PR.
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>
Manage auth and connect to 500+ apps using Composio. Perform real actions from Claude Code - send emails, create issues, post messages, and more.
Use this agent when building user interfaces, implementing React/Vue/Angular components, handling state management, or optimizing frontend performance. This agent excels at creating responsive, accessible, and performant web applications. Examples:\n\n<example>\nContext: Building a new user interface\nuser: "Create a dashboard for displaying user analytics"\nassistant: "I'll build an analytics dashboard with interactive charts. Let me use the frontend-developer agent to create a responsive, data-rich interface."\n<commentary>\nComplex UI components require frontend expertise for proper implementation and performance.\n</commentary>\n</example>\n\n<example>\nContext: Fixing UI/UX issues\nuser: "The mobile navigation is broken on small screens"\nassistant: "I'll fix the responsive navigation issues. Let me use the frontend-developer agent to ensure it works perfectly across all device sizes."\n<commentary>\nResponsive design issues require deep understanding of CSS and mobile-first development.\n</commentary>\n</example>\n\n<example>\nContext: Optimizing frontend performance\nuser: "Our app feels sluggish when loading large datasets"\nassistant: "Performance optimization is crucial for user experience. I'll use the frontend-developer agent to implement virtualization and optimize rendering."\n<commentary>\nFrontend performance requires expertise in React rendering, memoization, and data handling.\n</commentary>\n</example>
