Capture an entire web page as a full-page screenshot using Chrome DevTools Protocol, Chrome's developer control interface. The workflow needs no additional dependencies and provides page images for portfolios, case studies, and audit reports.
Review website images and reduce file sizes while limiting visible quality changes. Check compression, formats, display dimensions, loading behavior, and delivery settings, then recommend suitable tools or build automation and verification in browser DevTools.
Plan and evaluate free calculators, generators, or assessment tools for marketing. Compare ideas by audience needs, search demand, and development effort, then outline essential features, email signup options, promotion, and success metrics.
Audit page loading speed with Chrome DevTools MCP, a tool connection for browser inspection. Measure performance indicators, investigate network delays and layout shifts, check accessibility gaps, and produce prioritized fixes with estimated impact and relevant code findings.
Provides and generates LangChain4j tool and function calling patterns: annotates methods as tools with @Tool, configures tool executors, registers tools with AiServices, validates tool parameters, and handles tool execution errors. Use when building AI agents that call tools, define function specifications, manage tool responses, or integrate external APIs with LLM-driven applications.

Investigate unexpected costs in the ECC Tools GitHub App by tracing events, queued jobs, analysis workers, and billing logic. Identifies repeated pull request creation, usage-limit bypasses, unintended premium-model calls, and duplicate retries, then verifies targeted fixes.
Review how a website behaves when images fail to load and add fallback images or meaningful placeholder content. Check loading behavior, consider loading placeholders, and use error logging and browser developer tools to investigate and verify fixes.
Control and inspect a live Chrome browser through Chrome DevTools MCP. Automate page interactions, capture screenshots, inspect errors and network requests, and record performance data to investigate slow loading and unexpected layout changes.
Verify desktop UI changes through the Chrome DevTools Protocol, a connection for controlling the running app. Reproduce the user’s actual steps and compare screenshots, measured state, and console errors to establish evidence before and after a fix.
Assess Bluetooth Classic devices such as older car kits, industrial sensors, and audio accessories. The skill guides device discovery, service inspection, authentication checks, and known vulnerability assessment, helping document exposed functions and device-specific findings.
Prepare screenshots and network traffic records for bug bounty submissions by masking session secrets and personal data while preserving useful verification details. The skill covers capture setup, HAR cleanup, evidence filenames, and credential handling after submission.
Automatically discover life science APIs online, create ToolUniverse tools, validate them, and prepare integration PRs. Performs gap analysis to identify missing tool categories, web searches for APIs, automated tool creation using devtu-create-tool patterns, validation with devtu-fix-tool, and git workflow management. Use when expanding ToolUniverse coverage, adding new API integrations, or systematically discovering scientific resources.

Build Claude Code hooks, automated checks triggered by events such as tool use or session start. The guidance covers prompt-based decisions, command scripts, configuration, testing, and debugging for validation and workflow automation.
A deprecated guide to building MCP servers with mcp-use, covering callable actions, data resources, reusable prompts, and interactive widgets. It includes design references and code examples, and directs users to the replacement skill, mcp-app-builder.
Audit page speed in a real browser to find delays in loading, script execution, and layout. Use measured results to identify bottlenecks, compare device and connection conditions, and guide performance improvements.
Build Claude Code plugin hooks: automated checks triggered by tool use or session events. Get guidance on prompt and command hooks for validating actions, checking task completion, loading context, and testing configurations.
Audit MCP servers, which provide external tools to AI agents, for hidden instructions, changes after approval, unsafe internal requests, and missing authentication. Use mcp-scan and manual checks to document risks and recommended fixes.
Customize a project's Docker environment with personal tools such as vim, ripgrep, or jq. The skill prepares user override files, adds requested packages, and provides rebuild commands while keeping personal configuration out of Git.
Operate Agent Zero projects, chats, and tasks, or develop new tools, extensions, and API features. The skill guides work through existing APIs, relevant documentation, current source code, and checks appropriate to the change.
Build Claude Code plugin hooks: automated checks triggered by tool use or session events. Get guidance on prompt and command hooks for validating actions, checking task completion, loading context, and testing configurations.
Set up language servers, programs that help tools understand source code, for Go, TypeScript, Python, and Rust. Check missing prerequisites, install them with approval, and verify the lsp tool against a real source file.
Build Claude Code plugin hooks: automated checks triggered by tool use or session events. Get guidance on prompt and command hooks for validating actions, checking task completion, loading context, and testing configurations.
Pre/post dev toolbox — named bundles of skills/agents loaded before development work and councils of experts invoked after. Run /toolbox or the toolbox.py CLI to list, activate, initialize, export, import, and validate toolboxes. Invoke at the start or end of a dev session, when setting up a new repo, or when sharing toolboxes with a team.
