What You Can Do

You can instantly access up-to-date documentation for any developer technology—from React and Next.js to Django and AWS SDKs. This skill resolves library names to their official documentation and pulls current API signatures, configuration options, and code examples, ensuring you're always working with the latest version information. Perfect for API syntax questions, version migration issues, setup instructions, and debugging library-specific behavior.

Features

Resolve any library name to its official documentation

handles frameworks, SDKs, CLI tools, and cloud services

Retrieve current API signatures and method documentation

never rely on potentially outdated training data

Pull configuration options and setup instructions

verify exact syntax and required parameters

Access version-specific documentation

query docs for specific library versions when needed

Get code examples and usage patterns

see real examples from official docs, not from training data

Support for well-known and niche libraries

works equally well for React, Prisma, Spring Boot, or lesser-known tools

CLI-based workflow

uses Context7 CLI for reliable, direct access to documentation sources

Example Output

Example 1: React Hook Documentation

Query: "How do I clean up useEffect with async operations?"

Result:

code
// Cleanup function for async operations in useEffect
useEffect(() => {
  let isMounted = true;
  
  const fetchData = async () => {
    const result = await fetch('/api/data');
    if (isMounted) {
      setData(result);
    }
  };
  
  fetchData();
  
  return () => {
    isMounted = false; // Cleanup
  };
}, []);

Example 2: Next.js Deployment Configuration

Query: "What are the environment variables for Vercel deployment?"

Result: Current docs showing NEXT_PUBLIC_* prefixes, build settings, and vercel.json configuration options with latest API syntax.

Example 3: TypeScript + Express Setup

Query: "How do I set up Express with TypeScript?"

Result: Step-by-step setup with current package versions, tsconfig settings, and middleware configuration from the latest Express documentation.

Implement Task

You can deploy this agent to execute specific implementation tasks within a larger development plan. It operates independently with fresh context, follows test-driven development principles for every code change, and creates comprehensive handoff documentation that captures progress, decisions, and learnings for the next task executor. This ensures consistent code quality, prevents rework, and maintains continuity across distributed implementation efforts.

Integration Spec
$30
Integration Spec

You'll generate detailed integration specifications that bridge business requirements and technical implementation. The skill documents API endpoints and contracts, defines field-by-field data transformations with business rules, specifies error handling and retry strategies, and establishes SLAs with monitoring criteria—giving development teams everything needed to build production-ready integrations between systems.

Full-Stack Feature Development Workflow

Full-Stack Feature Development Workflow

You'll transform high-level feature requirements into a complete development plan covering API design, frontend implementation, testing strategy, and documentation. The skill helps you identify dependencies, parallelize work across frontend and backend teams, and establish quality gates that ensure features ship bug-free with proper error handling and logging.

Move/Rust Smart Contract Audit Reviewer

Rust/Move3.9(34)
Move/Rust Smart Contract Audit Reviewer

Conduct comprehensive security reviews of Move and Rust smart contract code to catch vulnerabilities before mainnet deployment. Claude analyzes resource handling, witness access patterns, input validation, privilege escalation vectors, memory safety concerns, and arithmetic operations—providing concrete code remediation examples and optimization recommendations tailored to Aptos, Solana, Substrate, and Cosmos ecosystems.

Audit Env Variables

Full-Stack4.7(51)
Audit Env Variables

You can perform a complete audit of your project's environment variables to discover unused configurations, identify which services are integrated (Stripe, AWS, Supabase, etc.), and understand permission scopes. The skill maps exactly where each variable is used in your codebase, then optionally removes unused variables with automatic regression detection to prevent breaking changes.

Debug

Full-Stack4.4(51)
Debug

You can systematically investigate application failures by examining logs, querying database state, and reviewing git history to identify root causes. This skill helps you understand the current state of your system without making changes, providing the contextual foundation needed to solve bugs efficiently during manual testing or implementation work.

Debug Hooks
$25
Full-Stack4.4(42)
Debug Hooks

You can systematically diagnose why hooks aren't firing, producing incorrect output, or behaving unexpectedly. This skill guides you through verification steps—checking hook registration, confirming file existence, testing hooks manually, and identifying silent failures—to pinpoint the exact cause of hook breakdowns and implement targeted fixes.

Code Review Checklist

Full-Stack4.6(50)
Code Review Checklist

This skill performs multi-dimensional code audits that go beyond surface-level feedback. You submit code in any major language (Python, JavaScript, Java, Go, Rust, etc.), and Claude systematically examines it against structured criteria: security vulnerabilities, performance anti-patterns, maintainability issues, test coverage gaps, naming conventions, and architectural pattern compliance. Each finding includes severity levels, remediation steps, and corrected code examples.
