Provides Playwright-powered browser automation that detects dev servers, writes tests to /tmp, launches a visible Chromium, and exercises login flows, responsive layouts, form submissions, link checks, or any browser task to validate web functionality.

Automates Plisio workflows through Composio’s Rube MCP toolkit by always discovering current schemas, managing toolkit connections, and running multi-execute tool calls with session-aware workflows.

Automates Plotly chart creation by offering step-by-step guidance, best-practice patterns, and production-ready code or configuration whenever visual content, diagrams, or presentations need charts.

Automates Claude Code plugin audits whenever audit or security keywords appear, checking for vulnerabilities, compliance with CLAUDE.md standards, marketplace/MCP requirements, best practices, documentation, and repository hygiene before emitting a structured report.

This guide details the recommended pattern for managing per-project plugin settings and state within a development environment. Plugins store their configuration in a dedicated `.claude/plugin-name.local.md` file. This file utilizes YAML frontmatter for structured settings (like enabling flags, retry counts, and parameters) and a Markdown body for additional context or instructions. It provides techniques for reading these settings using Bash hooks, commands, and agents.

This guide details the standardized directory structure and best practices for building robust and maintainable plugins for Claude Code. It covers critical components including the plugin manifest (plugin.json), commands, agents, skills, and hooks. Use this skill when you need to scaffold a new plugin, understand the required component organization, or configure the plugin's architecture according to best practices.

Guides API integration teams through polling mechanism setup, offering best practices, code samples, and validation to ensure reliable third-party connectivity.

Automate Polygon tasks through Rube MCP and Composio’s toolkit by always discovering current tool schemas, validating active Polygon connections, and running schema-compliant executions across workflows.

Guide for orchestrating Polygon IO tasks through Composio’s Rube MCP toolkit, covering tool discovery, connection validation, execution, and best practices for schema-compliant automation.

Use Composio’s Poptin toolkit with Rube MCP to automate tool discovery, connection checks, and multi-tool execution workflows for any Poptin tasks while always querying RUBE_SEARCH_TOOLS first to respect live schemas.
