WebAssembly with Emscripten skill for C/C++ to WASM compilation. Use when compiling C/C++ to WebAssembly with emcc, configuring EXPORTED_FUNCTIONS, understanding the WASM memory model, using Asyncify for async C code, debugging .wasm with browser devtools or wasm-opt, or targeting WASI vs browser environments. Activates on queries about Emscripten, emcc, WebAssembly from C/C++, WASM memory model, Asyncify, EXPORTED_FUNCTIONS, WASI, or wasm-opt.
Cloudflare Workers local development with Wrangler, Miniflare, hot reload, debugging. Use for project setup, wrangler.jsonc configuration, or encountering local dev, HMR, binding simulation errors.
Diagnose and fix MCP server connection issues between Claude Code, Claude Desktop, and MCP servers. Covers Windows argument parsing, authentication failures, transport issues, and platform-specific debugging. Use when Claude Code or Claude Desktop fails to connect to an MCP server, when MCP tools don't appear in sessions, on "cannot attach the server" errors, when a working connection has stopped, or when setting up MCP on a new machine.
Architect, build, and debug Kafka Streams apps (JVM-embedded stream processing). Use when user mentions KStream, KTable, topology, TopologyTestDriver, StreamsBuilder, interactive queries, GlobalKTable, joins/windows/aggregations, or debugging issues (rebalancing, state stores, lag, deserialization errors). Also use when user wants to optimize Kafka Streams for WarpStream or tune Kafka Streams client configuration for WarpStream. Do NOT trigger for Flink, connectors, CDC, or plain producer/consumer.
Audit a Duvo Assignment — or a multi-Assignment workflow connected by a Case Queue — across many Jobs to find systemic inefficiencies and quality issues, then recommend concrete SOP and architecture changes. Use when the user asks to "analyze this workflow", "audit my Assignment", "why is this Assignment slow / inconsistent / low quality across runs", "why does my queue keep backing up", or wants a health check over an Assignment's recent Jobs — as opposed to debugging one failed Job (that's job-debugger). Reads recent Jobs, eval scores, the producer/consumer queue topology, and the SOPs those Jobs actually ran against via the Duvo public API; hands off to sop-writer for any SOP rewrite.
Apply when debugging. Trace each symptom to its root cause and fix it there; reproduce first, ask why until you reach it, resist nil-check guards that silence crashes.
Use when writing or debugging OAS geometry — points, polygons, line segments, arcs, circles, spirals, fillets, units, or coordinate conventions. Load before any geometry-heavy edit.
Expert in building and testing conda/bioconda recipes, including recipe creation, linting, dependency management, and debugging common build errors
Fix broken AI features. Use when your AI is throwing errors, producing wrong outputs, crashing, returning garbage, not responding, or behaving unexpectedly. Covers DSPy debugging, error diagnosis, and troubleshooting.
Frontend website debugging toolkit using Chrome DevTools Protocol with Playwright/WebKit fallbacks. Use this skill when: (1) Debugging CSS, HTML, or JavaScript issues on a webpage, (2) Taking screenshots to verify visual changes, (3) Inspecting DOM structure or console errors, (4) Testing responsive layouts, (5) Extracting selectors for automation, (6) Self-debugging frontend work Claude has created, (7) User says "debug this page", "check my site", "why doesn't this look right", or "fix the frontend". Supports Chrome (primary) and Safari/WebKit (via Playwright). Designed for agent-driven debugging loops.
Debug Crossplane compositions, functions (KCL, Go templates, patch-and-transform, auto-ready), and managed resources. Use when troubleshooting composition rendering issues, function errors, resource creation failures, dependency problems, or claim status issues. Supports remote cluster debugging when composition files are not available locally. Triggers on keywords like "crossplane", "composition", "XR", "claim", "function-kcl", "managed resource", or when debugging Kubernetes resources created by Crossplane.
Fetch and analyze AppSignal error incidents. Use when debugging errors, investigating exceptions, or when the user mentions AppSignal, incidents, or error monitoring.
