Claude Code

A repository of agent skills from HumanLayer designed to enhance Claude Code and other AI coding assistants with specialized development workflows. The collection includes skills for improving instruction adherence in CLAUDE.md files, refining React component type definitions, and building agentic coding loops with GitHub Actions integration. Each skill is installed via the npx skills command and invoked through slash commands within your development environment. The toolkit enables developers to automate code quality improvements, create iterative agent workflows, and generate visual explanations with diagrams and artifacts.

Key Features

CLAUDE.md instruction file enhancement using conditional importance blocks for better agent adherence
React prop type narrowing that analyzes live code paths and removes test-only or mock-only type definitions
Agentic loop builder that scaffolds local skills plus GitHub Actions workflows with prompts and memory files
Control loop designer that interviews developers to create custom sensor-controller-actuator patterns tailored to specific codebases
Visual explanation skill that generates concise diagrams, code sketches, and focused HTML artifacts
NPM-based installation system allowing selective skill addition to projects
Slash-command invocation interface for quick skill execution during coding sessions
Repository-local skill architecture enabling customization and iteration

Use Cases

  • 01Refactoring CLAUDE.md configuration files to improve AI assistant instruction following and context awareness
  • 02Cleaning up overly broad TypeScript prop types in React codebases to reflect actual production usage
  • 03Setting up automated coding agent workflows that iterate on code improvements via scheduled GitHub Actions
  • 04Designing and implementing custom agentic control systems for monitoring and maintaining specific code patterns
  • 05Generating quick visual explanations and diagrams during code reviews or pair programming sessions
  • 06Building reusable local skills for team-specific development patterns and workflows
