io.github.nexu-io/open-design/webgl-aurora-veil

io.github.nexu-io/open-design/frame-flowchart-sticky

SVG curve connectors, sticky-note nodes, and cursor interaction with a whiteboard-brainstorm feel.

io.github.nexu-io/open-design/pptx-html-fidelity-audit

Audit a python-pptx export against its source HTML deck, identify layout/content drift (footer overflow, cropped content, missing italic/em, lost styling, off-rhythm spacing), and re-export with strict footer-rail + cursor-flow layout discipline. Use this skill whenever the user has a .pptx that was generated from an HTML slide deck and asks to compare/audit/verify/fix the export — including phrases like "compare ppt with html", "fidelity audit", "fix the pptx", "ppt is cut off", "footer overlap", "italic missing in pptx", "re-export the deck", "pptx-html-fidelity-audit", or any case where a python-pptx → HTML round-trip needs verification or repair. Also trigger when the user shows you a deck.html and a deck.pptx side by side and is debugging visual differences.

io.github.nexu-io/open-design/webgl-depth-gallery

A scroll-reactive 3D image gallery in Three.js: Z-stacked images crossfade over per-image mood backgrounds with velocity breath, a glowing cursor trail and an editorial CMYK/RGB/HEX/PMS color card.

io.github.PostHog/posthog/setting-up-a-custom-rest-source

Connect an arbitrary REST API to the PostHog data warehouse as a Custom source by authoring a JSON manifest, with no per-source code. Use when the user points at an API that has no built-in PostHog connector — "import data from this REST API", "sync my internal API", "connect this API from its docs", "build a custom data warehouse source" — and gives a docs URL or a natural-language description of the endpoints. Walks through drafting the RESTAPIConfig manifest (auth — bearer, API key, HTTP basic, or OAuth2 client credentials / refresh token — pagination, record path, incremental cursor, parent/child fan-out), validating it, test-reading live rows to verify the field mappings, and creating the source. If the API already has a native PostHog connector, use setting-up-a-data-warehouse-source instead — this skill checks the connector registry first and only handles APIs with no native connector.

io.github.paperclipai/paperclip/paperclip-distill

Use when an operation issue is a Paperclip cursor-window, distill, or backfill. Turn source-bundled Paperclip activity into wiki-insightful project standups, durable project pages, decisions, and history without asset dereferencing.

io.github.affaan-m/ECC/ui-demo

io.github.pingdotgg/t3code/scratchpad

Extract the JSDoc example nearest the active source selection or cursor into ./scratchpad as a TypeScript file. Use when the user asks to dump, copy, open, or try a source example in scratchpad.

io.github.electric-sql/electric/electric-proxy-auth

Set up a server-side proxy to forward Electric shape requests securely. Covers ELECTRIC_PROTOCOL_QUERY_PARAMS forwarding, server-side shape definition (table, where, params), content-encoding/content-length header cleanup, CORS configuration for electric-offset/electric-handle/ electric-schema/electric-cursor headers, auth token injection, Bun fetch concurrency cap (BUN_CONFIG_MAX_HTTP_REQUESTS default 256), ELECTRIC_SECRET/SOURCE_SECRET server-side only, tenant isolation via WHERE positional params, onError 401 token refresh, and subset security (AND semantics). Load when creating proxy routes, adding auth, or configuring CORS for Electric.

SVG curve connectors, sticky-note nodes, and cursor interaction with a whiteboard-brainstorm feel.

io.github.ReadyToGo-Education/fluxo_criativo/css-effects

Aplica efeitos visuais CSS e JavaScript em qualquer elemento de site — texto, cards, botões, formulários, navegação, modais, imagens, loaders, scroll, cursor, fundos, e microinterações. Use SEMPRE que o usuário pedir para "adicionar efeito", "deixar mais bonito", "animar", "modernizar", "tornar interativo", "estilizar", "deixar profissional", ou enviar print/screenshot/descrição de um elemento (botão, card, título, seção, navbar, hero, formulário, menu, modal) pedindo melhorias visuais. Também ativa em pedidos como "que efeito posso usar aqui", "sugere algo legal pra essa parte", "como deixar esse site mais interessante", "essa seção tá sem graça", "como faz aquele efeito do site X", ou qualquer pergunta sobre o que cada efeito CSS faz e como funciona. Use mesmo se o usuário não citar "CSS" explicitamente — qualquer pedido de melhoria visual em UI web aciona esta skill. Também ativa quando o usuário diz que está construindo um site, landing page, portfolio, dashboard, e quer torná-lo memorável ou competitivo.
