Skill UI

This skill provides a comprehensive guide for creating production-quality custom Semgrep rules. It teaches best practices for detecting security vulnerabilities, enforcing robust coding standards, and identifying specific bug patterns. By emphasizing a test-first approach and utilizing advanced techniques like taint mode, users can write highly accurate static analysis rules that drastically reduce false positives.

This skill provides a structured workflow for porting existing Semgrep security rules to multiple target languages. It guides users through applicability analysis, test-first rule creation, and validation for each language variant, ensuring consistent and accurate security coverage across polyglot codebases.

This skill provides a systematic methodology for iteratively improving complex skill documentation. By utilizing a reviewer agent, it identifies and categorizes issues (Critical, Major, Minor) in a structured loop. The process ensures that the skill meets high standards of quality, reliability, and functional completeness before deployment, moving beyond simple manual edits.

A comprehensive, canonical workflow for defining, writing, and improving complex AI skills. It guides users through a structured, multi-step process, including resolving targets, synthesizing information, enforcing depth gates, authoring artifacts, optimizing descriptions, and conducting thorough evaluation and validation.

This skill provides a robust and safe mechanism for updating SpecKit templates and configurations from GitHub. It is designed to automatically apply the latest changes while meticulously preserving any existing project customizations, ensuring a non-disruptive workflow. It features a conversational, two-step approval process, guiding the user through the update process, reporting conflicts, and handling fresh installations gracefully. Ideal for developers needing reliable, version-controlled updates to their SpecKit environment.

Provides a static code analysis capability that inspects source files without running them, helping developers catch issues early in the build pipeline.

This tool systematically audits a project's dependencies to identify potential supply chain security risks. It evaluates critical factors such as maintenance status, contributor count, popularity, and the presence of high-risk features. It is ideal for pre-security audits, assessing the overall attack surface, and mitigating risks before deployment.

Provides curated testing handbook techniques, summarizing workflows and readiness checks for QA teams looking to standardize quality assurance practices.

Master the complete animation pipeline within Three.js. This resource covers everything from creating custom keyframe tracks (position, quaternion, color) to managing complex animations using AnimationMixer and AnimationAction. Learn about procedural motion, animation blending (crossfading), morph targets, and loading skeletal animations from GLTF files for realistic 3D experiences.

This guide provides a comprehensive overview of the core concepts of Three.js, the leading JavaScript library for WebGL 3D rendering. It covers setting up the entire 3D environment, including the Scene, Camera types (Perspective, Orthographic), and the WebGLRenderer. Users will learn to handle object hierarchies, apply transforms (position, rotation, scale), and manage complex rendering settings like lighting, shadows, and environment maps. Essential for any developer starting a WebGL project.

Master the creation and manipulation of 3D geometry within the Three.js framework. This guide covers built-in primitive shapes (Box, Sphere, Cylinder), advanced procedural geometries (Extrude, Tube, TorusKnot), and text visualization. Crucially, it details the use of BufferGeometry, allowing developers to store vertex, normal, UV, and color data in optimized typed arrays for high-performance rendering and custom mesh construction.

A comprehensive guide to implementing various lighting techniques in Three.js, covering Ambient, Directional, Point, Spot, and RectArea lights. Learn how to configure realistic shadow maps, optimize lighting performance, and achieve high visual fidelity for your 3D web scenes.
