Troubleshooting guide for Code Executor MCP issues - diagnose hanging, import errors, and connection problems
Systematic debugging discipline that enforces root cause investigation BEFORE fixes. Triggers on - bug, error, failing, broken, fix, not working, crash, issue, debug, investigate, diagnose, trace, root cause, why is, undefined, null, 500 error, RLS, timeout, infinite loop, exception, stack trace. Integrates with Zen MCP, TodoWrite, and verification-before-completion. Aligns with fail-fast engineering principle.
Systematic backward tracing through call chains to find where bugs originate. Triggers on debug, trace, root cause, call stack, error, exception, bug, investigate, find the source, test pollution, flaky test, bisect, why is this failing, where does this come from, track down. Integrates with mcp__zen__debug for hypothesis-driven investigation.
Debug the scoreboard UI in Chrome using DevTools MCP. Inspect page state, console errors, network requests, and interact with elements. Use when debugging UI issues, checking for JS errors, or testing user interactions.
Guide for implementing Cloudflare Browser Rendering - a headless browser automation API for screenshots, PDFs, web scraping, and testing. Use when automating browsers, taking screenshots, generating PDFs, scraping dynamic content, extracting structured data, or testing web applications. Supports REST API, Workers Bindings (Puppeteer/Playwright), MCP servers, and AI-powered automation. (project)
Controls Chrome browser: takes screenshots, clicks buttons, fills forms, downloads images, inspects pages, captures network requests, checks console errors, debugs API issues. Use when: 'screenshot', 'click', 'fill form', 'download image', 'check browser', 'look at screen', 'capture page', 'check for errors', 'debug network', 'API failing', 'console errors'. Provides MCP tool discovery for 70 tabz_* browser automation tools.
Token-efficient codebase exploration using MCP-first approach. Locates functions, classes, patterns, and traces dependencies with 80-90% token savings. Use when searching code, finding implementations, or tracing call chains.
Use when debugging web applications or automating browser tasks. Leverage Chrome DevTools MCP for inspection, performance analysis, and automated testing.
Audits web performance using Chrome DevTools MCP. Measures Core Web Vitals, finds render-blocking resources, dependency chains, layout shifts, caching issues, and accessibility gaps. Use for audits, profiling, debugging, or optimising page load performance and Lighthouse scores.
Use this skill when you need to discover MCP tool parameters, understand naming conventions, or debug tool call errors
Deep code intelligence via Narsil MCP providing 76 tools for security scanning (OWASP, CWE, taint analysis), call graph analysis (CFG, DFG, callers/callees), structural queries (symbols, definitions, references), and supply chain security (SBOM, license compliance). Accessed via Code Mode for token efficiency.
UI component generation patterns for IntelliFill. Replaces magic/21st.dev MCP to save ~3.4k tokens.
Creates a new Starlark MCP extension with tools, handlers, and proper structure. Use when the user wants to add a new extension to the starlark-mcp server.
