Upload local artifact files or directories (HTML reports, screenshots, analysis bundles, any static files) to the team's Cloudflare R2 share bucket and return a public unguessable https://share.fun.country/<slug>/... URL. Use when the user says 'upload this to cloudflare somewhere I can share', wants a link to drop in Slack, or wants a local HTML report viewable by teammates. Requires a secret env file at ~/.config/cf-share/env (see references/setup.md). Not for deploying apps or product content (ps-content CDN), not for claude.ai Artifacts, and not for material that must stay private.

Add internationalization (i18n) to a Nuxt 3 project — install @nuxtjs/i18n, extract hardcoded strings from components into locale JSON files, configure routing strategy, create a language switcher component, and fix hosting config for SSR locale routes. Use this skill whenever the user wants to translate a Nuxt site, add multiple languages, add a language switcher, localize content, or migrate a monolingual Nuxt site to multilingual. Also triggers when adding specific languages (e.g., "add German to my site") or when the user mentions i18n, localization, or translation in a Nuxt context.

Seed a new or empty Instagram account with a 9-post grid (3×3) so the profile looks established the moment a new visitor lands. Designed for festivals, new businesses, product launches, conferences, communities — any time an empty IG profile would hurt conversion from external traffic (QR scans, flyer drops, cross-promo). Generates assets via /image-from-gemini (per content-publishing rules — never HTML), writes captions with hashtag sets, and outputs a posting order + cadence plan. Trigger generously: phrases like '9 posts for instagram', 'fill my IG', 'starter grid', 'launch grid', 'instagram seed', '9-post grid', 'IG account not to look empty', 'first instagram posts', 'feed bootstrap', '3x3 grid', 'instagram launch content'. Even if the user mentions only one piece (just the images, just the captions, just the order), use this skill — the grid only works as an integrated bundle.

aelaguiz Bundle

Use as a Flutter app-building reference for architecture, code quality, Dart style, state management, lifecycle, performance, rendering, testing, CI, accessibility, localization, security, platform integration, and Flame/game-loop guidance. Use when authoring, reviewing, repairing, or diagnosing Flutter mobile apps or games. Do not use for non-Flutter frontend work, generic visual design, running Flutter tooling, or latest Flutter/Dart facts without checking official docs.

aelaguiz Bundle

Build, restyle, or audit Google Sheets (and Excel) workbooks so a human can read, scan, change and trust them: header-only frozen rows, one line per cell, merges only for group headers, numbers right and text left, consistent number formats, one documented colour key, and every number owned: observations shown as data, assumptions styled as inputs, everything derived as formulas. Use when the user asks to make a spreadsheet readable, consistent, presentable or user-friendly, to fix freeze panes, paragraphs in cells, hardcoded numbers or inconsistent formatting, to apply a house style through the Sheets API or gws CLI, or to audit a sheet's formatting. Not for choosing the analysis or metrics, data cleaning or statistics, chart or dashboard design outside the grid, or HTML/PDF report styling.

mcj-coder Skill

Build, structure, and ship web apps/sites with the Hono framework — the the user default for new sites and for converting React SPAs to SSR. Use when the user wants to create a Hono app, convert/remake a site in Hono, add SSR + islands on Cloudflare Workers, set up Hono routing/middleware/JSX, choose between hono/jsx (server) and hono/jsx/dom (client), wire the Vite build, or asks "is this Hono", "make it Hono", "Hono SSR", "Hono on Workers", "@hono/jsx", "islands", "hono framework". Loads current, verified Hono API patterns so you leverage the framework fully instead of guessing from memory.

Reverse-engineer ANY binary, bundle, distributable, OR the private API of a website you're logged into. Binaries — compiled native (.exe/.dll/.so/.dylib/Mach-O), JVM (.jar/.apk/.dex), .NET (.dll/.exe IL), iOS (.ipa), browser extensions (.crx/.xpi), WebAssembly (.wasm), Python bytecode (.pyc), React Native Hermes (.hbc), JS bundles, firmware blobs, installers (.deb/.rpm/.dmg/.msi). Websites — record a real logged-in session to HAR (incl. the log-out/log-in auth handshake), distill it, and generate a typed TypeScript client + MCP server. Routes to the correct tool per artifact class — Ghidra is just one tool in the kit. Use when the user says decompile, disassemble, reverse-engineer, RE, "look inside this binary/app/extension/firmware", "make an API/MCP server for this website", "capture the network calls this site makes", HAR, triage malware, audit a binary for vulns, diff functions across versions, or port a closed-source thing to a CLI. Does NOT debug or pentest live websites — for debugging route to /debug

Deep multi-source research on a topic across a 10-provider search stack via the `websearch` CLI with automatic quota failover — self-hosted SearXNG and Marginalia (both keyless/unmetered), Linkup, Parallel, You.com, Tavily, Brave, Jina, Exa, TinyFish — plus the Exa MCP for filtered/semantic search and full-page crawling. Fans out queries, reads sources, adversarially verifies every load-bearing claim, and synthesizes a cited HTML report. Use when the user says 'deep research', 'research <topic>', 'dig into <topic>', 'deepsearch', '/deepsearch', or wants a thorough, fact-checked, multi-source brief — NOT a single quick lookup (use the plain WebSearch tool for that).

barkleesanders Skill

Drive the macOS GUI (click / type / scroll / drag / screenshot any native app) from Claude or any CLI via the open-source `cua` command — real hardware CGEvents (cliclick) + screenshots (screencapture) + Accessibility element finding (osascript). No Codex, no cloud vision, no reverse-engineering. Ships a Cobra CLI AND an MCP server (`cua_*` tools). Use when the user wants to operate a native Mac app, automate a desktop task, take over a GUI, click a control that ignores synthetic clicks (file pickers, Chrome/Polymer toggles, "Load unpacked"), or asks about "computer use", "control my Mac", "drive an app", "click/type in <app>", "cua". Replaces the old /computer-use-bridge skill.

Default output format for reports, summaries, analyses, dashboards, audits, comparisons, digests, briefings, and any deliverable with structured/spatial information. Generates a single self-contained HTML file (no external dependencies) the user can open in a browser, share, print to PDF, or paste into Notion. Lightweight cousin of /design and /magazine — no AI generation server, no editorial chrome, just clean Tailwind-via-CDN HTML that beats Markdown on scannability, comparison, and feel. Use whenever the user asks for a report, summary, breakdown, analysis, audit, dashboard, comparison, or any deliverable that previously would have been a .md file. Triggers: 'report', 'summary', 'audit', 'analysis', 'dashboard', 'compare', 'breakdown', 'rundown', 'brief', 'digest', 'overview', 'recap', 'write up', 'document', 'deliverable'.
