Create or inspect Jinkō data tables via the jinko-sdk. Use this skill whenever the user wants to upload observed data for trial overlays or calibration objectives from CSV, SQLite, or pandas DataFrame; check data-table schema columns; inspect existing data tables; or verify metadata.public.validForFitnessFunction. Do not use this skill for output sets; use jinko-output-set for that.
Create or update a Jinkō document from markdown through the jinko-sdk, including headings, tables, code blocks, links to Jinkō project items, uploaded images, and links to existing Jinkō References. Use this skill whenever the user wants to turn local markdown into a Jinkō document, refresh an existing document from edited markdown, prepare markdown so Jinkō renders cards and images correctly, or cite existing project References.
Product management and design-adjacent skills distilled from Lenny Rachitsky's podcast and newsletter archive, with named frameworks, checklists, and templates per skill. The catalogue installs the design-relevant ones: customer interviews, continuous discovery, feedback analysis, product reviews, onboarding and activation, PRDs, growth model, product taste, AI-native UX, and AI-assisted prototyping. The full library covers strategy, hiring, growth, and leadership too.
Expert-level Looker BI, LookML, explores, dimensions, measures, dashboards, and data modeling. Use when the user mentions LookML, BI, analytics, dashboards, or data modeling, or when the task involves LookML Basics, Advanced Dimensions and Measures, Persistent Derived Tables, or Explores and Joins.
Create high-quality Markdown weekly reports, work reports, summaries, introductions, and similar documents. If there is no draft, search the web and summarize; if there is a draft, organize, polish, and supplement it. Use when the user mentions a weekly report, work report, summary, introduction, performance review, or retrospective.
Migrate i18next/react-i18next projects to Lingui. Use when the user wants to replace i18next, react-i18next, useTranslation, i18n.t(), Trans i18nKey, or i18next JSON catalogs with Lingui equivalents. Covers package installation, config setup, code transformation patterns, plural migration, namespace handling, and catalog conversion.
Writing-time discipline for the prose an agent speaks to a human (replies, reports, pointers): a protected core never rewritten (code, commands, paths, errors, negators, numbers), filler dies, no narration, auto-clarity where terse misleads
Expert-level MongoDB database design, aggregation pipelines, indexing, replication, and production operations. Use when the user mentions NoSQL, database, aggregation, or performance, or when the task involves CRUD Operations, Query Operators, Aggregation Pipeline, or Indexing.
A complete guide to developing MusicFree music player plugins from scratch. Trigger when the user asks to write, create, or develop a MusicFree plugin, or adapt a music website or API into a MusicFree plugin. Covers the full process, including the plugin protocol, media type definitions, method signatures, sandbox environment, site analysis, local debugging, and publishing updates. This Skill is designed for AI execution and guides AI in collaborating with beginners to develop plugins.
Parse, navigate, and query materials science ontology structures — browse class hierarchies, inspect individual classes and their properties, look up object and data property definitions with domain/range, search for ontology terms by keyword, and parse or summarize raw OWL/XML files. Currently supports CMSO and ASMO; the broader OCDO ecosystem (CDCO, PODO, PLDO, LDO) is planned. Use when exploring what classes or properties an ontology provides, finding the right CMSO term for a crystal structure or simulation concept, understanding parent-child class relationships, or onboarding to an unfamiliar materials ontology, even if the user only says "what ontology terms describe my FCC copper simulation" or "show me the CMSO class hierarchy."
Gameplay development role for Phaser 4 mobile 2D games. Use to implement, recreate, refactor, or validate core loops, scenes, interactions, states, and testable features based on GDDs, TDDs, numerical design, and reference inputs, and collaborate with artists on production visual integration.
Create, edit, and analyze presentations. Use when Claude needs to work with presentations (.pptx) to: (1) create new presentations, (2) modify or edit content, (3) work with layouts, (4) add comments or speaker notes, or perform any other presentation task
Proofread and correct text for grammar, spelling, punctuation, style, clarity, and consistency, with support for multiple style guides and readability analysis. Use when the user requests proofreading or provides relevant inputs for this workflow.
Applies Qt Canvas2D (QtCanvas2D / Qt Canvas Painter, Qt 6.12+) best practices when producing or working with Canvas2D QML source code. Use whenever Canvas2D, Canvas2DContext, path2d, boxshadow2d, boxgradient2d, gridpattern2d, conicalgradient2d or transform2d is the subject: writing, reviewing, fixing, optimizing, or porting Qt Quick Canvas / HTML5 canvas drawing code to Canvas2D. Also use for GPU-accelerated imperative 2D drawing in QML — gauges, dials, charts, waveforms, oscilloscopes, clocks, freehand drawing — including choosing between Canvas2D and Shape/ShapePath when the renderer has not been decided yet. Do NOT trigger for plain Qt Quick Canvas work that must stay on the old CPU element, or for reviewing existing Shape/ShapePath code where the renderer is already settled.
Turn vague product, offer, benchmark, or campaign inputs into high-quality short-form script objects for AI UGC videos and TikTok or Instagram slideshows. Use this when the user needs hook variants, script variants, slideshow flows, reveal timing, proof logic, and downstream handoff artifacts rather than one-off copy. This skill should guide weak inputs into testable scripts, not merely rewrite them more naturally.
When the user wants to monitor reviews, mentions, and community sentiment about their own product. Also use when the user mentions "track our reviews", "what are people saying about us", "brand monitoring", "reputation management", or "review alerts"
Official Software Mansion skills for React Native and Expo: production patterns for animations (Reanimated), gestures, SVG, on-device AI, rich text, multithreading, audio and JSI, plus skills for RNRepo prebuilt libraries, Radon IDE debugging, TypeGPU, Meta Quest, Pulsar haptics, Fishjam streaming, Media over QUIC and Detour deep linking. From the team behind Reanimated and Gesture Handler.
Construir protótipos descartáveis para responder uma pergunta técnica, de interação ou visual com custo e fidelidade mínimos. Use para spikes, provas de conceito e exploração de alternativas; não promover protótipo a produção sem reimplementação e validação.
AI design agent for coding agents: design or redesign frontend UI, presentations and marketing graphics on the hosted Superdesign infinite canvas, with project context read from your code and branchable drafts you refine. Works through the @superdesign/cli package.
Survey Writer — writes sections of review papers according to a template. Activate when assigned writing by a research lead or paper analyst. Uses paper analysis cards and comparison tables to write a complete review paper in accordance with academic writing standards.
Background context for the Electronic Bookkeeping Act (電子帳簿保存法) in the shinkoku tax filing plugin. Contains requirements for electronic bookkeeping, scanner storage, mandatory electronic transaction data storage, and shinkoku's compliance status. This skill is not user-invocable — Claude loads it automatically when responding to electronic bookkeeping compliance questions.
Use when optimizing 3D models for web delivery: reducing file size, compressing meshes, optimizing textures, or generating LOD. Provides a complete GLTF optimization pipeline using Draco, KTX2, mesh simplification, and gltf-transform. Keywords: optimize model, reduce file size, Draco compression, KTX2, gltf-transform, mesh simplification, LOD, GLTF optimize, bundle size, model too big, slow loading, compress 3D model.
Decide whether an Upwork job post is worth applying to before spending Connects. Use when the user pastes an Upwork job post (or invitation) and wants a verdict (apply, skip, or apply with caution). Triggers include "is this job worth it", "should I apply", "check this job post", "is this client legit", "worth my Connects", "red flags in this job". Screens for scams, bad-client patterns, and dressed-up low-tier work, then weighs the Connects economics. Companion to upwork-proposal-writer (after an apply verdict) and upwork-invitation-responder (after a skip verdict on an invitation).
An Agent skill that turns long Markdown articles into 3:4 (1080×1440) image sets for Xiaohongshu. Includes five design skins (E Elegant Journal · default / A Warm Apricot Latte / B Misty Pine Green / C Ink and Gold / D Gilded Night Reading) plus three women-oriented themes (F Pink Kingdom / G Otome Game Night / H Ghibli) × multiple page layouts. The Agent reads the article, splits it into pages, and fills in HTML; the Playwright renderer captures and exports each image as PNG. Use when the user says “turn a long article into images”, “Xiaohongshu long image”, “turn this article into Xiaohongshu graphics/images/cards”, “article to images”, “typeset with my design draft”, “convert to a 3:4 image set”, wants a “women-oriented/girly/pink/otome-game/Ghibli-style” layout, or provides an article and mentions posting it on Xiaohongshu.
Interactively onboard a project to OpenSpec by running a structured interview and generating a complete QRSPI-configured openspec/config.yaml. Use this skill whenever a user mentions "openspec config", "config.yaml for openspec", "set up openspec", "onboard to openspec", "generate openspec config", "QRSPI config", or asks how to configure OpenSpec for their project — even if they just say "help me set up openspec" or "I want to use openspec". Always prefer this skill over ad-hoc config generation.
Creating algorithmic art using p5.js with seeded randomness and interactive parameter exploration. Use this when users request creating art using code, generative art, algorithmic art, flow fields, or particle systems. Create original algorithmic art rather than copying existing artists' work to avoid copyright violations.
