Technology-agnostic guidance for modular systems: bounded contexts, clear boundaries, composability, state isolation, explicit contracts, failure containment, scaffolding workflows, split/merge criteria, sub-units inside a context, and compliance review signals. Use when designing or reviewing module structure, service boundaries, package layout, cross-cutting dependencies, "how should we split this?", modularity assessments, coupling between domains, greenfield context design, or architecture discussions without assuming a specific framework, language, or repository layout.

Routes across 33台词, ClipSeek/open media, local files, ListenHub, image generation, HTML/SVG/Canvas motion graphics with beat-grid storyboards and determinism probes, Manim, ffmpeg-full, captions, sound design, and release checks.
Expert guidance for building reusable UI components in Rails using partials, CSS classes, and helpers. Use when creating components, partials, reusable UI patterns, empty states, modals, cards, buttons, badges, alerts, data tables, or any component pattern. Covers decision framework for CSS-only vs partial vs helper vs ViewComponent, proper use of local_assigns, block yielding, capture for slots, variant patterns, and component galleries.
When the user wants to create, optimize, or analyze a referral program, affiliate program, or word-of-mouth strategy. Also use when the user mentions 'referral,' 'affiliate,' 'ambassador,' 'word of mouth,' 'viral loop,' 'refer a friend,' or 'partner program.' This skill covers program design, incentive structure, and growth optimization.

Create notarized macOS app releases with Sparkle auto-updates, DMG installers, and GitHub releases. Use when releasing macOS apps, creating DMG files, notarizing apps, or setting up Sparkle updates. Handles version updates, code signing, notarization, and distribution.
Write a single-paragraph Deep Research prompt to hand to a human researcher (or a deep-research AI). Use when the user wants a research brief, a "deep research prompt", a one-paragraph task for a researcher, or asks "what should our researcher look for". Produces ONE tight paragraph with full context, numbered sub-questions, and per-finding output format.
Agentic RSS digest using the feed CLI. Fetches, triages, and summarizes RSS feeds to surface high-signal posts. Use when reading RSS feeds or catching up on news; when a digest, roundup, or summary of recent posts is requested; when asked what’s new or interesting today; or when feed, RSS, or blogs are mentioned.
Reduce Claude Code token burn with proactive compacting, task-scoped sessions, checkpoint files, tiered docs, and relevance-based context pruning. Use when a user explicitly asks to reduce context usage/cost, run token benchmarks, or optimize CLAUDE.md. Do not use to expand product scope or skip correctness checks
Escape the build trap and endless backlogs. Use Basecamp's methodology to ship meaningful work in 6-week cycles with fixed time, variable scope. Use when: **Product planning** to replace endless backlogs; **Feature development** with clear time boundaries; **Team autonomy** when you want self-directed teams; **Scope management** when projects tend to balloon; **Startup development** with limited resources

Strips the cues that make a website read as AI-generated and forces a deliberate, project-specific design choice instead of the model's default. It does not impose a look or hand you taste. It removes tells (default shadcn/Tailwind, AI-purple gradients, gradient heading text, unprompted neon glow, emoji-as-icons, the centered hero plus three feature cards) AND the newer cream-plus-serif-plus-sage "tasteful default" that trading one default for another creates. Grounded in a 47-subreddit, 3.2M-post Reddit analysis of what people flag as AI slop. Use whenever building, styling, reviewing, refactoring, or auditing any website, landing page, web app UI, dashboard, or front-end component, especially when the user wants a site to look custom or human rather than AI-generated, or mentions AI slop, looks AI-made, generic, vibe-coded, Tailwind, or shadcn. Trigger even if they never say vibe-coded.
Use when you need to create a new Maven-based Micronaut 4.x project using SDKMAN-managed Java and Micronaut CLI tooling. This should trigger for requests such as Create a Micronaut Maven project; Bootstrap Micronaut project with SDKMAN; Generate a new Micronaut service; Create Micronaut 4 Maven project; Scaffold Micronaut service with Java 25. Part of Plinth Toolkit
New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
