Systematic root-cause debugging: reproduce, investigate, hypothesize, fix with verification. Use when asked to "debug this", "fix this bug", "why is this failing", "troubleshoot", or mentions errors, stack traces, broken tests, flaky tests, regressions, or unexpected behavior.
Multi-agent review of implementation plans. Use after creating a plan but before implementing, especially for complex or risky changes.
Creates realistic cloud effects for web using SVG filters (feTurbulence, feDisplacementMap), CSS animations, and layering techniques. Use for atmospheric backgrounds, weather effects, skyboxes, parallax scenes, and decorative cloud elements. Activate on "cloud effect", "SVG clouds", "realistic clouds", "atmospheric background", "sky animation", "feTurbulence", "weather effects", "parallax clouds". NOT for 3D rendering (use WebGL/Three.js skills), photo manipulation (use image editing tools), weather data APIs (use data integration skills), or simple CSS gradients without volumetric effects.
Executes full-project QA like a real user by discovering the repository verification contract, running build, lint, test, and startup commands, exercising core workflows end-to-end, creating realistic fixtures when needed, fixing root-cause regressions, and rerunning the full gate. Use when validating a branch, release candidate, migration, refactor, or risky commit. Do not use for static code review only, one-off unit test edits, or architecture brainstorming without execution.
Review generated or changed production code before it ships, using Clean Code, SOLID, DRY, KISS, YAGNI, and LLM-specific failure-mode checks in any programming language. Best used reactively after an agent writes, edits, refactors, or fixes code, before presenting, committing, or merging the result. Use when the user asks "review this PR", "is this safe to merge?", "make this cleaner", "audit this code", "refactor this", "fix this bug", or after a coding agent produced implementation code. Can also guide writing when explicitly invoked before a risky edit. DO NOT USE for factual/conceptual questions, CI/tooling config, git workflow, running/debugging tests, pure architecture discussion, prose writing, data analysis, or test-code review (use test-guard).
Bootstrap new Hugo sites with Sveltia CMS and Basecoat UI, or convert existing sites (any SSG or CMS) to Hugo + Sveltia CMS. Use this skill whenever the user mentions Hugo, Sveltia CMS, Decap CMS migration, TinaCMS migration, static site CMS setup, headless CMS for Hugo, or wants to add a content management interface to a Hugo site. Also trigger when converting WordPress, Jekyll, Eleventy, TinaCMS, or other sites to Hugo, or when setting up Git-based content management. Covers the full workflow from scaffolding through Cloudflare Pages deployment with GitHub OAuth authentication.
Create attention-grabbing hooks and headlines using 15 proven formulas, sticky techniques, and the 4 U's test. This skill provides systematic frameworks for generating volume (10+ options) and selecting the best performers. Use for newsletter subject lines, social media hooks, blog headlines, or any content that needs to stop the scroll.
Expert patterns for 3D level design using GridMap with MeshLibrary, CSG constructive solid geometry, WorldEnvironment setup, ProceduralSkyMaterial, and volumetric fog. Use when building 3D levels, modular tilesets, BSP-style geometry, or environmental effects. Trigger keywords: GridMap, MeshLibrary, set_cell_item, get_cell_item, map_to_local, local_to_map, CSGCombiner3D, CSGBox3D, CSGSphere3D, CSGPolygon3D, WorldEnvironment, Environment, Sky, ProceduralSkyMaterial, PanoramaSkyMaterial, fog_enabled, volumetric_fog_enabled.
Use only when writing/updating/fixing C++ tests, configuring GoogleTest/CTest, diagnosing failing or flaky tests, or adding coverage/sanitizers.
Axios - promise-based HTTP client for browser and Node.js USE WHEN: user mentions "Axios", "HTTP requests", "API calls", "interceptors", "Axios instance", asks about "how to make HTTP calls", "configure Axios", "add auth header", "handle HTTP errors" DO NOT USE FOR: Fetch API - use `http-clients` instead; ky/ofetch - use `http-clients` instead; GraphQL clients - use `graphql-codegen` instead; tRPC - use `trpc` instead
Extract tables, form fields, and document layout from PDFs or images (scanned PDFs, PNG/JPG) using Syncfusion Smart Data Extractor. Trigger when users ask to parse/extract/convert document data (invoices, receipts, KYC/forms) into structured output and want C#/.NET integration code using the extractor.
Build Solana trading applications combining DFlow trading APIs with Helius infrastructure. Covers spot swaps (imperative and declarative), prediction markets, real-time market streaming, Proof KYC, transaction submission via Sender, fee optimization, shred-level streaming via LaserStream, and wallet intelligence.
