Web & Frontend

danmossa Bundle

Use when writing SpacetimeDB TypeScript or JavaScript clients, generated TS bindings, `DbConnection`, `DbContext`, query builders, subscriptions, reducer events, cache callbacks, React provider/hooks, Vue, Svelte, browser, Node, Bun, Deno, Next.js, Nuxt, Remix, TanStack, or Angular integrations. Triggers on: TypeScript SDK, JavaScript SDK, useSpacetimeDB, useTable.

dathere Skill

Build an interactive HTML dashboard — a Data Schematic — with charts, filters, and tables. Use when creating a dashboard, an executive overview with KPI cards, turning query results into a shareable self-contained report, building a team monitoring snapshot, or needing multiple charts with filters in one browser-openable file.

discountry Skill

Detect, review, prevent, and remove AI-generated UI convergence patterns ("AI slop") in frontend code. Use whenever building or styling a UI, reviewing frontend changes, refining visual design, or when the user asks to remove the AI look, make an interface feel human-designed, polish a page, audit UI quality, or explain why a design feels generic. Covers HTML, CSS, JSX/TSX, Vue, Svelte, and Tailwind; audits 46 catalogued patterns plus composition-level checks, separates source-confirmed, rendered, and judgment-based evidence, and rewrites authorized code toward a product-specific design direction without requiring external dependencies.

discountry Bundle

React best practices for component design, state management, and Effect discipline. Use when writing, reviewing, or refactoring React components, custom hooks, or any .ts/.tsx/.js/.jsx file that uses React.

discountry Skill

Write, review, and debug `useEffect` correctly. Use whenever touching React code that contains an Effect — authoring a new one, reviewing a diff that includes one, or debugging symptoms like a spinner that never resolves, UI stuck in a loading/pending/verifying phase, a button permanently disabled, an Effect that fires twice or loops forever, a fetch race condition, a cleanup that cancels the wrong request, a stale closure reading old props/state, or a `react-hooks/exhaustive-deps` warning. Also use for setInterval / setTimeout / subscriptions / AbortController inside Effects, StrictMode double-invocation questions, multi-step async flows and state machines driven by Effects, and any .tsx/.jsx/.ts/.js file where `useEffect`, `useLayoutEffect`, or a custom hook wrapping them appears.

duthaho Bundle

Community-pulse research on any topic — "what are people saying about X right now." Fans out parallel sub-agents across web search, Hacker News, Reddit, and GitHub; ranks findings by real engagement (points/upvotes/stars/comments); flags rumors; and writes a cited brief to chat plus saved .md and .html files. Use when the user wants the current community conversation / recent buzz / sentiment / "last 30 days" view on a person, product, project, or concept — e.g. "/pulse <topic>", "what's the buzz on X", "what are people saying about X lately", "research recent discussion on X". For exhaustive, adversarially fact-checked web reports, prefer the deep-research skill instead.

duthaho Bundle

Human-facing documentation, architecture docs, and mermaid diagrams for a codebase, a module, or a feature — "draw me the architecture, with receipts." Fans out read-only sub-agents to build a grounded component graph first: every node is a real path, every edge backed by a grep-verified import or call — unverifiable edges are dropped, not drawn. Diagrams render from that verified table per a fixed checklist (never freehand mermaid), capped at 5–8 top-level components with drill-down pages; every doc section cites its sources as file:line. Drafts in chat, writes docs/blueprint/ only on your yes, and stamps a manifest with date + commit so /blueprint refresh regenerates only what the diff touched. Use for "generate an architecture diagram", "document this codebase or module for people", "create a mermaid diagram of this feature" — e.g. "/blueprint", "/blueprint the payment flow", "/blueprint refresh". For agent-facing orientation (AGENTS.md) use map; blueprint is the human-facing sibling.

pixiesgeosun Bundle

Use this skill when a task needs browser automation through PinchTab: open a website, inspect interactive elements, click through flows, fill out forms, scrape page text, log into sites with a persistent profile, export screenshots or PDFs, manage multiple browser instances, or fall back to the HTTP API when the CLI is unavailable. Prefer this skill for token-efficient browser work driven by stable accessibility refs such as `e5` and `e12`.

arkan Bundle

Create a self-contained HTML file for whatever the user is describing, in the effective HTML style. Use when the user wants an HTML artifact that isn't specifically a diagram or a plan — a report, explainer, comparison, deck, prototype, or anything else best delivered as one HTML file.

arkan Bundle

arkan Bundle

Create a self-contained HTML file for visualizing architecture and understanding the stack with a high-quality SVG diagram. Use when the user wants a full-screen diagram, wants the output to be light on prose, or wants an HTML artifact that is mostly there to make the architecture click fast.

open-gsd Skill

Plan, batch, and verify dependency upgrades safely. Triages outdated packages into risk tiers, upgrades in order (dev/minor/patch first, runtime majors last), verifies each batch, and produces an auditable commit sequence. Use when asked to "upgrade deps", "bump packages", "update node_modules", "fix vulnerabilities", "upgrade React/Node/TypeScript", or after `/gsd start dep-upgrade`.

pdbjork Skill

Ship a redesigned (or new) static website end-to-end on a VPS — design the site, build it, validate it, deploy to a static mirror under /var/www or equivalent, smoke-test nginx (with the right Host header) AND the backend capture service, write a handoff report, and ping the user. Load when the user asks to "redesign", "build", "ship", "deploy", or "publish" a website, especially a research/education/foundation/nonprofit public-facing site where privacy-by-default, consent-first forms, and "no false claims" discipline matter. Skip for SPA / SSR app deploys (Next.js, Vite, etc.) — those have their own build pipelines. Skip for hosted-platform-only deploys (Vercel/Netlify/Cloudflare Pages with no VPS mirror).

gastownhall Bundle

Implements any user intent, requirement, story, bug fix or change request by producing clean working code artifacts that follow the project's existing architecture, patterns and conventions. Use when the user wants to build, fix, tweak, refactor, add or modify any code, component or feature.

freightcognition Skill

Use when creating workflow editors, data flow diagrams, organizational charts, mindmaps, process visualizations, DAG editors, or any interactive node-graph UI. Supports custom nodes/edges, layouts (dagre, hierarchical), animations, and advanced features like proximity connect, floating edges, and contextual zoom.

witooh Skill

Ingest an external source (JIRA card, Confluence page, URL, image, HTML, text, or a verbal brief) once into `docs/knowledge/` as curated, reusable context — with provenance (source url, fetched_at, version/etag when available). The memory primitive that neo's ingest-first step depends on. Standalone — call it directly (`/ingest <url>`) to pre-warm the knowledge base, or neo triggers it when a task needs context that is not yet ingested. Triggers: "/ingest", "ingest <source>", "remember this", "add <url> to the knowledge base", or neo routing here during the ingest-first gate.
