Automation

Install Codex skills into $CODEX_HOME/skills from a curated list or a GitHub repo path. Use when a user asks to list installable skills, install a curated skill, or install a skill from another repo (including private repos).

This skill runs as a Stop hook at the end of Claude Code sessions to analyze conversation transcripts and extract reusable patterns. It identifies error resolutions, debugging techniques, workarounds, and project-specific conventions, saving them as learned skills for future reference.

Continuous Learning v2 is an advanced learning system that observes your Claude Code sessions through hooks, capturing tool usage patterns. It creates atomic 'instincts' with confidence scoring that can evolve into reusable skills, commands, and agents. The system learns your preferences and workflows to make Claude more personalized over time.

This skill provides comprehensive guidance for writing production-grade Bash scripts using defensive programming patterns. It covers strict mode settings, error trapping, safe variable handling, structured logging, and idempotent script design to help developers create reliable shell scripts for CI/CD pipelines, system administration, and automation tasks.

This skill helps manage major dependency version upgrades in JavaScript/TypeScript projects. It provides strategies for compatibility analysis, staged upgrade workflows, codemod automation, and comprehensive testing approaches including rollback plans and automated update configuration with Renovate or Dependabot.

Provides production-ready GitHub Actions workflow templates for common CI/CD tasks including automated testing, Docker image building, Kubernetes deployments, matrix builds, and security scanning. Templates follow best practices with pinned action versions, caching, and reusable workflows.

Intelligently organizes your files and folders across your computer by understanding context, finding duplicates, suggesting better structures, and automating cleanup tasks. Reduces cognitive load and keeps your digital workspace tidy without manual effort.

Automatically creates user-facing changelogs from git commits by analyzing commit history, categorizing changes, and transforming technical commits into clear, customer-friendly release notes. Turns hours of manual changelog writing into minutes of automated generation.

A comprehensive PDF processing skill that enables text and table extraction, PDF creation, merging and splitting documents, and form filling. It includes specialized scripts for handling both fillable and non-fillable PDF forms with visual validation workflows.

This skill provides a complete workflow for creating Claude Code skills. It includes scripts to initialize new skill directories with proper templates, validate skill structure and metadata, and package skills into distributable zip files. The skill also contains comprehensive documentation on skill anatomy, progressive disclosure patterns, and best practices for writing effective skills.

This skill scans your codebase to recommend tailored Claude Code automations. It analyzes your project's language, frameworks, and tools to suggest the most valuable hooks, skills, MCP servers, and subagents for your workflow. The skill is read-only and outputs recommendations without making any changes to your project.

This skill helps users create and optimize email marketing sequences including welcome series, lead nurture campaigns, re-engagement flows, and onboarding emails. It provides comprehensive templates, copy guidelines, and best practices for email automation without requiring any external integrations.

Multiagent AI system for scientific research assistance that automates research workflows from data analysis to publication. This skill should be used when generating research ideas from datasets, developing research methodologies, executing computational experiments, performing literature searches, or generating publication-ready papers in LaTeX format. Supports end-to-end research pipelines with customizable agent orchestration.

Hookify lets you create custom hooks that warn or block specific behaviors in Claude Code. Define rules in markdown files with regex patterns to catch dangerous commands, debug code, or enforce workflows - no complex configuration needed.

Ralph Loop implements continuous self-referential AI loops for interactive iterative development. It uses a stop hook to repeatedly feed the same prompt, allowing Claude to see and improve upon its previous work until completion criteria are met.

A code review skill that launches multiple AI agents to audit pull requests for bugs and guideline compliance, filtering results by confidence score to reduce false positives.

Feature Development provides a structured 7-phase workflow for building new features: discover requirements, explore the codebase with specialized agents, clarify ambiguities, design architecture, implement with approval, review quality, and summarize results. Uses code-explorer, code-architect, and code-reviewer agents in parallel for thorough analysis.

Automates common git operations with three commands: /commit for smart commits, /commit-push-pr for complete PR workflows, and /clean_gone for branch cleanup. Integrates with GitHub CLI for PR creation.

This skill provides comprehensive documentation for writing hookify rules - markdown files with YAML frontmatter that define patterns to watch for and messages to show when those patterns match. It covers rule file format, event types (bash, file, stop, prompt), regex pattern syntax, advanced conditions, and best practices for organizing rule files.

A comprehensive guide for creating Claude Code plugin hooks that automate validation, context loading, and workflow enforcement. Includes working example scripts for validating file writes and bash commands, plus utility scripts for testing and linting hook implementations before deployment.

This skill automates the creation of Claude Code skills from the Trail of Bits Testing Handbook (appsec.guide). It analyzes handbook content for security testing tools (static analysis, fuzzers), techniques (sanitizers, coverage), and domains (cryptography, web security), then generates properly structured skills using templates. The generator includes a two-pass system for content and cross-references, automated validation, and self-improvement workflows.

Claudeception enables Claude Code to build persistent knowledge by extracting reusable skills from debugging sessions and problem-solving. When you discover a non-obvious solution, workaround, or debugging technique, it captures that knowledge as a new skill that can be automatically retrieved in future sessions facing similar problems.

This skill provides instructions for using the tmux-cli command to communicate with other CLI agents or scripts running in different tmux panes. It enables executing commands in specific panes with exit code detection, useful for multi-step automation and agent coordination. Requires separate installation of the claude-code-tools package.

This skill sets up Geoffrey Huntley's 'Ralph Wiggum' autonomous coding technique - a bash loop that feeds prompts to Claude CLI for automated code generation. It supports planning mode (gap analysis) and building mode (implementation), with Docker isolation as an option for safer execution.

For CLI agents WITHOUT subagent support (e.g., Codex CLI). Search previous code agent sessions for specific work, decisions, or code patterns.

Expert guidance for creating, building, and using Claude Code subagents and the Task tool. Use when working with subagents, setting up agent configurations, understanding how agents work, or using the Task tool to launch specialized agents.

Expert guidance for creating, configuring, and using Claude Code hooks. Use when working with hooks, setting up event listeners, validating commands, automating workflows, adding notifications, or understanding hook types (PreToolUse, PostToolUse, Stop, SessionStart, UserPromptSubmit, etc).

This skill integrates the OpenAI Codex CLI with Claude Code, allowing users to run code analysis, refactoring, and automated editing tasks. It provides a structured workflow with explicit permission prompts before executing high-impact operations, and supports resuming previous Codex sessions.

This skill provides comprehensive guidance for end-to-end testing with Playwright. It covers Page Object Model patterns, authentication handling, cross-browser testing, network mocking, visual testing, and CI/CD integration with GitHub Actions.

This skill provides structured templates and best practices for iterative test-driven development using the Ralph Wiggum loop plugin. It guides Claude through self-referential development cycles where the AI iterates on code until tests pass, with clear completion criteria and error classification to distinguish between fixable code issues and environment blockers.
