chrisliu298 Skill

Fetch web pages or search the web via Jina AI (r.jina.ai / s.jina.ai). Use when WebFetch fails, returns empty/garbage, or for JS-heavy sites: x.com, Notion, SPAs, PDFs at a URL, Cloudflare-gated pages. Also use for grounded web search with full-page content. Triggers on "fetch this URL", "read this page", "search for", or after a WebFetch error. Do NOT use for simple static HTML.

chrisliu298 Skill

Read arxiv papers via their TeX source for full-fidelity math, tables, and figures. Use whenever the user shares an arxiv URL or paper ID and wants to discuss or understand the paper — even without "read". Triggers on arxiv URLs (abs, pdf, html), bare IDs like "2401.12345", or "explain this paper". Do NOT use for note generation (use note-gen).

React 19 + TypeScript for FMC TanStack Start apps: typed components, events, generics, ref-as-prop, Compiler-first memoization, and useEffect discipline (naming, when not to use Effect, alternatives). Use when typing React components/hooks/events, or writing/reviewing useEffect, useEffectEvent, derived state, data-fetch effects, or oxlint React Compiler / Rules of React effect rules. Not for routing/server boundaries (see tanstack-start-* skills).

react-map-gl/maplibre patterns for FMC geo apps: declarative Source/Layer (never addSource/addLayer), MapProvider + useMap(), interactiveLayerIds, flat Source/Layer, map-loaded guard, window.__mainMap debug exposure, Map event handlers (not useEffect), URL map state, initialViewState, cursor, feature state, missing images. Use when building or reviewing Map components, layers, click/hover handlers, setFeatureState, map URL sync, or agent/test map inspection in TanStack Start / Vite apps. Reference implementation: tilda-geo/app.

FMC conventions for Zustand v5 in React: file naming, custom-hook-only exports, atomic selectors, actions namespace, small focused stores. Use when adding or reviewing client global state, or debugging unnecessary re-renders and SSR/persist hydration issues. Not for server/async data (TanStack Query) or URL state (nuqs). For API details, middleware, slices, and migration, use the official llms.txt index below.

fixmyberlin Bundle

TanStack Router conventions for FixMyBerlin/FMC (SPA or Start): validateSearch with Zod, parseSearch/stringifySearch for clean share URLs, map=zoom/lat/lng search param, loader + React Query patterns, typed Link/params, and TanStack devtools.

luka-zivkovic Bundle

Publish an already-reviewed, digest-locked plan of GitHub PR thread replies and optional resolutions. Use only when the user explicitly invokes $publish-pr-feedback with the exact sealed plan path and SHA-256 digest, or explicitly asks this skill to seal a supplied draft plan for later approval. Verify host, repository, PR node, open state, current remote head, action scope, and plan digest before mutation. Do not judge feedback, edit code, invent or broaden replies, commit, push, merge, rebase, react, approve a PR, or run implicitly.

luka-zivkovic Bundle

Handle reviewer feedback on an open GitHub pull request. Use whenever the user asks to address, handle, work through, or resolve review comments, open review threads, or bot feedback; this includes prefetched thread data such as review/threads.json and a later approval message that asks the resolver to prepare its unsealed local plan. Fetch unresolved threads plus PR comments and review bodies, judge every item against actual code, apply valid local fixes within authorized scope, and draft replies. After a separate approval names an exact subset and root-confined plan path, prepare only that unsealed local plan. Never post, react, resolve, commit, push, merge, rebase, or approve; remote publication belongs only to explicit $publish-pr-feedback. Do NOT use to produce a new review, discuss one pasted comment, handle feedback without a PR, work on non-GitHub forges, or summarize without changes.

olzn Skill

Generate N different HTML implementations of a UI feature, preview them, and iterate a few times, a fast "show me the options" loop for exploring what a feature could look like. Default N is 5. Use when the user wants to prototype a UI, explore or compare designs for a feature, says "prototype this", "try a few designs", "explore some options for X", "what could this look like", or hands over a feature with no spec. Marks a quiet pick but does NOT collapse to one winner, research, implement, verify, or open a PR; a chosen direction hands off to the build skill, whose review gates check the result. For editable Paper artboards rather than throwaway HTML, use paper-prototype instead; for whether a state model, business logic, or data shape feels right, use logic-prototype.

olzn Bundle

Build a single-file HTML demo that answers whether a state model, business logic, or data shape feels right — a pure liftable module driven by free-play buttons and tabbed guided walkthroughs a non-developer can click through. Use when the user wants to sanity-check a state machine or reducer, probe an edge case ("what happens if X then Y"), feel out a data model or API shape before building it, or hand a domain expert something to poke at. For what a UI could look like use prototype; for editable Paper artboards use paper-prototype.

olzn Bundle

Create Paper-first UI prototype directions, especially after grill-with-docs has settled product and domain decisions. Use to explore layout, hierarchy, density, flow, or visual framing as editable Paper artboards before committing to code, to compare structurally distinct directions, or to turn settled product decisions into an interface. For throwaway HTML explorations rather than editable Paper frames, use the prototype skill instead. For business-logic or state-machine prototyping use logic-prototype, unless the user explicitly asks for Paper output.

olzn Skill

Run a post-implementation review that checks a built change against the intent that was set. Run lint, typecheck, tests, and build; confirm the result matches the chosen design direction and covers its promised states (loading, empty, error, disabled, permission, offline, long content, maximum volume, and partially complete data); check accessibility and responsive behaviour; flag any risky surface; and assemble the handoff evidence a reviewer needs. Read-only — it reviews and reports, it never edits. Invoked automatically by the build skill after implementation, and available manually after a build or a meaningful change, after ui-craft and before opening or finalising a PR, especially when the user asks to verify, review, sign off, sanity-check a built change before handoff, or asks whether a change is ready to ship.
