Mixedbread's official semantic grep: search code, text, PDFs and images in natural language, and hook it into Claude Code, Codex and other coding agents in one step to cut token use. Requires a Mixedbread sign-in, and files are synced to its cloud index.

Writes or rewrites English docs in the spirit of ASD-STE100 Simplified Technical English: short sentences, active voice, condition before command, one word one meaning, terms defined at first use. Plain mode by default, Strict mode for STE compliance, plus a rule-by-rule check mode.

Keeps agents from reporting done too early on substantial work: writes acceptance gates with runnable checks before starting, runs only user-approved commands, splits large jobs into a depth tree of verified leaves, and re-checks evidence before reporting. Optional Claude Code Stop hook.

Generates 26+ chart types with AntV, including line, bar, Sankey, word cloud, mind map and pivot table, returning image links. Officially maintained by Ant Group's AntV team; uses a public rendering service by default and can be self-hosted.

Spec-driven development MCP: the agent writes requirements, design and task docs in three steps, then implements task by task. A web dashboard or VS Code extension lets PMs review, comment, approve and track progress. Needs Node.js; launch the dashboard separately via npx.

Create, read and modify xlsx workbooks without Microsoft Excel installed: formulas, formatting and conditional formatting, charts, pivot tables and tables. Runs locally over stdio or as a remote HTTP service.

Three.js fundamentals with code: setting up the scene, cameras and WebGLRenderer, Object3D hierarchy, coordinate systems and transforms, the render loop and resize handling. A starting point for building a 3D scene on the web.

Three.js geometry reference with code: parameters for built-in shapes like boxes, spheres, cylinders and tori, building custom meshes from vertices with BufferGeometry, and instanced rendering for large numbers of objects.

Three.js interaction reference with code: raycasting for click detection and object selection, camera controls such as OrbitControls, and mouse and touch input handling for interactive 3D experiences.

Three.js lighting reference with code: ambient, hemisphere, directional, point, spot and area lights with their cost and shadow support, shadow setup, image-based environment lighting and lighting performance tips.

Three.js asset loading reference with code: loading GLTF models, textures, images and HDR environments, coordinating loaders and progress with LoadingManager, and async loading patterns.

Three.js materials reference with code: when to use Basic, Lambert, Phong, Standard, Physical, Toon and other materials, PBR properties such as roughness and metalness, custom ShaderMaterial and material performance.

Three.js post-processing reference with code: chaining passes with EffectComposer, adding bloom, depth of field, color grading, blur and glow, and writing custom screen-space shader passes.

Three.js shader reference with code: writing GLSL vertex and fragment shaders, ShaderMaterial versus RawShaderMaterial, uniforms and animating them, and extending built-in materials for custom visual effects.

Three.js texture reference with code: loading and configuring texture maps, UV mapping, cubemaps and HDR environment maps, texture settings and optimization.

Three.js animation reference with code: procedural motion with Clock, the AnimationClip, AnimationMixer and AnimationAction keyframe system, playing GLTF animations, skeletal animation, morph targets and blending multiple animations.

Open-source marketing plugin with 48 skills: SEO and AI search optimization (GEO), GA4 and Search Console analysis, ad diagnostics for Google, Meta, X, LinkedIn, Reddit and TikTok, and WordPress upkeep. Some SEO skills need only a URL; live data requires NotFair OAuth and linked accounts.

Expo's official plugin covering Expo Router navigation, native UI, data fetching and SDK upgrades, plus EAS builds, OTA updates and app store submission. Some service-related skills rely on paid EAS.

Expo's official skills: Expo Router navigation, native-feeling UI, animations, native modules and SDK upgrades, plus EAS build and submit, OTA updates and CI workflows. EAS skills use Expo's paid services.

From Dagger: gives each coding agent its own container and git branch so multiple agents work in parallel without interfering, with command logs and the ability to take over the terminal at any time. Connects via MCP; needs Docker and Git. Still experimental.

From Dagger: gives every coding agent an isolated container and Git branch so several agents can work in parallel, and you can view command logs, take over the terminal or discard results anytime. Needs Docker and Git locally; still experimental.

Hugging Face's official hf CLI: search, download and upload models and datasets, manage repos and storage buckets, and run jobs on Hugging Face's cloud. Output adapts automatically for agents, and hf skills add installs companion skills. Uploads and similar actions need a login.

Knownsec's open-source Python-use agent: describe a task in plain language and it writes and runs Python on your machine, e.g. tidying Excel files, summarizing attendance or screening resumes. Needs Python 3.11+ and a model API key such as DeepSeek; code runs locally, so back up important files.

Guides SwiftUI view building: choosing @State, @Binding, @Observable or @Environment by ownership, wiring TabView, NavigationStack and sheets, async loading with .task, small composed views and previews, plus anti-patterns and a component reference index.
