Upload, sync, and manage files across cloud storage providers using rclone. Use when uploading files (images, videos, documents) to S3, Cloudflare R2, Backblaze B2, Google Drive, Dropbox, or any S3-compatible storage. Triggers on "upload to S3", "sync to cloud", "rclone", "backup files", "upload video/image to bucket", or requests to transfer files to remote storage.
Browser automation using Vercel's agent-browser CLI. Use when you need to interact with web pages, fill forms, take screenshots, or scrape data. Alternative to Playwright MCP - uses Bash commands with ref-based element selection. Triggers on "browse website", "fill form", "click button", "take screenshot", "scrape page", "web automation".
Verify Home Assistant YAML for DRY and efficiency issues by detecting redundant trigger/condition/action/sequence structures and repeated blocks across automations, scripts, and packages. Use when creating, reviewing, or refactoring YAML in config/packages, config/automations, config/scripts, or dashboard-related YAML where duplication risk is high.
Deprecate a public API (class, method, property, type, constant, or context token) following the 2-major-version rule. Use when removing or replacing any publicly exported symbol that external consumers may depend on — includes exports from package index.ts files, global components, extension type aliases, and manifest schemas.
Create a new workspace for an entity in the Umbraco backoffice. Supports two workspace types — default (simple, manifest-only, for root/listing pages) and routable (entity detail editing with create/edit flows). Use when the user says "create a workspace", "add a workspace for X", or "scaffold a workspace". For routable workspaces, the entity must already have a package, entity type, repository, and data source.
Official skill for the XcodeBuildMCP CLI. Use when doing iOS/macOS/watchOS/tvOS/visionOS work (build, test, run, debug, log, UI automation).
Test browser extensions in real browsers using built artifacts, Edge + Playwright automation, runtime-message triggering, DOM debugging, and truthful screenshot capture.
GEO-first SEO analysis tool. Optimizes websites for AI-powered search engines (ChatGPT, Claude, Perplexity, Gemini, Google AI Overviews) while maintaining traditional SEO foundations. Performs full GEO audits, citability scoring, AI crawler analysis, llms.txt generation, brand mention scanning, platform-specific optimization, schema markup, technical SEO, content quality (E-E-A-T), and client-ready GEO report generation. Use when user says "geo", "seo", "audit", "AI search", "AI visibility", "optimize", "citability", "llms.txt", "schema", "brand mentions", "GEO report", or any URL for analysis.
Full website GEO+SEO audit with parallel subagent delegation. Orchestrates a comprehensive Generative Engine Optimization audit across AI citability, platform analysis, technical infrastructure, content quality, and schema markup. Produces a composite GEO Score (0-100) with prioritized action plan.
AI crawler access analysis. Checks robots.txt, meta tags, and HTTP headers to determine which AI crawlers can access the site. Provides a complete access map and recommendations for maximizing AI visibility while maintaining appropriate control.
Technical SEO audit with GEO-specific checks — crawlability, indexability, security, performance, SSR, and AI crawler access
Frontend design skill fused from Impeccable + custom extensions. Covers design philosophy, anti-AI-slop patterns, typography, color (OKLCH), spatial design, motion, interaction, responsive, UX writing, state management, engineering, and 4 style variants. Includes 20 command skills for audit/critique/polish/animate/etc.
Systematically audits any Armeria-based Java project for event loop blocking issues — discovers project patterns, scans for blocking operations, traces call chains, and produces a fix plan without modifying code. Use when experiencing latency spikes, connection timeouts, deadlocks, or thread starvation in Armeria services, or as a pre-release audit. Invoked as `/eventloop-audit` for the full project or `/eventloop-audit <path>` for a specific directory.
Pyrogram Telegram机器人开发技巧：解析消息链接、自定义Session超时、避免视频黑屏上传、去除消息广告。Use when working with Pyrogram, parsing Telegram message links, uploading videos, or removing advertisement content from messages.
Automatically diagnose Mooncake deployment and runtime issues. Checks services (mooncake_master, metadata server), RDMA devices, environment variables, connectivity, memory limits, and analyzes logs for common error patterns. Use when Mooncake deployment fails, services won't start, connections fail, or you encounter runtime errors like "Error from etcd client", "No matched device found", "Failed to register memory", "NO_AVAILABLE_HANDLE", or any RDMA/networking issues. Also use when user asks to troubleshoot, debug, diagnose, or fix Mooncake problems.
Meta-skill for understanding and customizing Mindfold Trellis — the AI workflow system for Claude Code and Cursor. Documents the original Trellis system design including architecture, commands, hooks, and multi-agent pipelines. Use when understanding Trellis architecture, customizing workflows, adding commands or agents, troubleshooting issues, or adapting Trellis to specific projects. Modifications should be recorded in a project-local trellis-local skill, not here.
Claude Code + Codex parallel pipeline for bootstrapping Trellis coding specs. CC analyzes the repo with GitNexus (knowledge graph) + ABCoder (AST), creates Trellis task PRDs with full architectural context and MCP tool instructions, then Codex agents run those tasks in parallel to fill spec files. Use when: bootstrapping coding guidelines, setting up Trellis specs, 'bootstrap specs for codex', 'create spec tasks', 'CC + Codex spec pipeline', 'initialize coding guidelines with code intelligence'. Also triggers when user wants to set up GitNexus or ABCoder MCP for multi-agent spec generation.
Frontend full-chain performance optimization guide based on Web Vitals metrics. Provides metric thresholds, diagnostic methods, and optimization strategies for LCP, FCP, INP, CLS, TTFB, TBT. Use when optimizing frontend performance, analyzing Web Vitals, reducing page load time, fixing layout shifts, improving interaction responsiveness, or reviewing frontend code for performance issues.
Collaborative requirements discovery session optimized for AI coding workflows. Creates task directories, seeds PRDs, runs codebase research, proposes concrete implementation approaches with trade-offs, and converges on MVP scope through structured Q&A. Use when requirements are unclear, multiple implementation paths exist, trade-offs need evaluation, or a complex feature needs scoping before development.
Deep post-fix bug analysis across five dimensions: root cause categorization, fix failure analysis, prevention mechanisms, systematic expansion, and knowledge capture. Updates .trellis/spec/ guides with lessons learned to prevent recurring bugs. Use when a debugging session completes, after fixing a tricky bug, when the same class of bug keeps recurring, or when you want to capture debugging insights into project documentation.
