Full three-perspective audit of an existing website from one URL — design (tensions + concrete improvement opportunities), SEO/technical, and LLM/AI-search visibility — plus Core Web Vitals, synthesized into a scored, evidence-bound report. Use when the user asks to “audit this site”, “site audit”, “design audit”, “SEO audit”, “why is my site underperforming”, “LLM visibility”, “how does my site look to AI”, or invokes `$stardust audit` (`/stardust:audit` in Claude Code) <url>
Expert guidance for developing cross-platform desktop applications with Avalonia UI framework. Use when building, debugging, or optimizing Avalonia apps including MVVM architecture, XAML design, data binding, styling, theming, custom controls, and cross-platform deployment for Windows, macOS, Linux, iOS, Android, and WebAssembly.
Apply modern web development best practices for security, compatibility, and code quality. Use when asked to "apply best practices", "security audit", "modernize code", "code quality review", or "check for vulnerabilities". Do NOT use for accessibility (use web-accessibility), SEO (use seo), performance (use core-web-vitals), or comprehensive multi-area audits (use web-quality-audit).
Match spoken edit beats to candidate B-roll assets using a normalized transcript, subtitle chunking, optional A-roll analysis, and a reusable B-roll catalog. Use this when the goal is to decide what B-roll should support each beat, not just to list assets or describe the video
Use when identifying, auditing, or tracking character archetypes in fiction. Trigger on: 'character archetype', 'archetype audit', 'what archetype is this character', 'archetype conformance', 'Hero's Journey character role', 'Jungian archetype', or archetype-based character analysis.
Diagnose and fix Core Web Vitals issues on AEM Edge Delivery Services pages. Goes deeper than generic CWV advice by understanding EDS-specific performance patterns including the 100KB LCP budget, E-L-D loading phases, block rendering behavior, and third-party script impact. Produces specific fixes for LCP, CLS, and INP issues with before/after projections. Use when the user asks about Core Web Vitals, page speed, or performance issues on AEM Edge Delivery Services (EDS/Franklin) sites.
Deploy or publish Python and R content to a Posit Connect server using rsconnect-python or the R rsconnect package. Handles interactive apps and dashboards, web APIs, rendered documents, and prepared bundles/manifests. Use whenever the user asks to deploy, publish, or redeploy content to Posit Connect, or mentions rsconnect. Consult this skill instead of guessing flags or commands.
Create well-structured RFCs and technical proposals for software projects. Use this skill whenever the user wants to write an RFC, technical proposal, design doc, architecture doc, or system design overview. Also trigger when the user says things like "write an RFC", "I need to propose a new system", "create a technical proposal", "document the architecture", "write up the design", "I need a design doc", or "explain the system architecture in a doc". Even if they just say "RFC", "design doc", or "arch doc", use this skill. Covers both RFCs (proposing what to build) and architecture docs (documenting an existing codebase).
Review failed Exarchos MCP tool calls from the current session, diagnose root causes, and categorize into code bug, documentation issue, or user error. Use when the user says 'dogfood', 'review failures', 'what went wrong', 'triage errors', or runs /dogfood. Scopes exclusively to Exarchos tools (exarchos_workflow, exarchos_event, exarchos_orchestrate, exarchos_view, exarchos_sync). Do NOT use for debugging application code or non-Exarchos tool failures.
A tool for querying Douyin’s daily like-surge rankings. It collects Douyin posts across the platform daily and outputs a TOP50 list of posts with the largest single-day increase in likes. Supports category-based queries and looking back at dates up to 30 days. Use when users ask for Douyin surge rankings, like surges, ranking surges, or new Douyin likes. Trigger terms: Douyin surge ranking, like surge, surge ranking, surge list, Douyin surge, new Douyin likes.
Call use_skill as your first and only action when the user asks to run, start, or debug a Mule application. This includes executing applications in run or debug mode. Trigger phrases include “run my project,” “run all projects,” “debug my project,” “debug all my projects,” “start the app,” “run <project-name>,” and “debug <project-name>.” When you call use_skill, it must be the only tool call in that response.
Diagnoses and fixes flaky tests by identifying root causes (timing issues, shared state, randomness, network dependencies) and provides stabilization strategies. Use for "flaky tests", "test stability", "intermittent failures", or "test debugging".
Expert blueprint for party games including minigame resource system (define via .tres files), local multiplayer input (4-player controller management), asymmetric gameplay (1v3 balance), scene management (clean minigame loading/unloading), persistent scoring (track wins across rounds), and split-screen rendering (SubViewport per player). Use for Mario Party-style games or WarioWare collections. Trigger keywords: party_game, minigame_collection, local_multiplayer, asymmetric_gameplay, split_screen, dynamic_input_mapping.
Implements secure JWT (RFC 7519) signing and verification using HMAC-SHA256, RSA-PSS, ES256, and EdDSA, including token expiration, claims validation, and defenses against algorithm-confusion, none-algorithm, and key-injection attacks. Use when adding or hardening JWT-based authentication/authorization, or auditing token verification code for common JWT vulnerabilities
Use when the user wants to publish or schedule to Instagram through Publora: a single image, a 2–10 image carousel, a Reel, or a Story. Requires a Business account and an image or video; text-only posts are rejected by the API. Not for Threads (use threads-post)
Keboola platform context — automatically load this whenever working on any Keboola Python component task (developing, testing, debugging, reviewing, schema design). Contains platform-level knowledge about how the Keboola Connection platform executes components, manages configuration, handles state, and runs jobs. This is not about code patterns — it is about platform behaviour that affects how code should be written and tested. Always pull this before making decisions about config structure, row handling, state, parallelism, or test data layout.
Create mathematical animations with Manim Community Edition(manimce), with optional TTS voiceover and synced subtitles. Generates distinctive, production-grade animations that avoid generic "AI slop" aesthetics. Use when the user wants to animate concepts, equations, illustrate proofs, visualize algorithms, create math explainers, or produce 3Blue1Brown-style videos
Assess whether index gains or declines are supported by sufficient market breadth, and identify whether the trend reflects healthy broad participation, narrow concentration, or a weak rebound. Suitable for evaluating overall market health, interpreting index trends, and making position decisions.
The composed executor that lands a subagent worktree branch onto an integration branch with preflight + recorded recovery point. For a shared integration branch route through `serialize_merge` (the single-writer lease that composes this action); invoke `merge_orchestrate` directly only for a non-integration merge or when you already hold the lease. Triggers: operator (or `next_actions`) surfaces the merge verb via Exarchos MCP. Local git operation — NOT remote PR merging (that is `merge_pr`).
For musicians, video creators, and social-media editors producing AI music videos or emotional short films with lyric typography. Users provide music, lyrics, references, characters, typography direction, mood, or target platform. The Skill analyzes beat and vocal timing, separates character, scene, and text references, designs beat-reactive spatial typography, decomposes long works into connected shots, audits prompts, and routes generation for H3 or other video tools. It outputs MV concepts, shot prompts, lyric text plans, and stitching guidance. Best for stylized MVs and subtitle-driven music visuals, not ordinary caption cleanup, licensed IP copying, or fully manual post-production editing.
Expert NIST AI Risk Management Framework (AI RMF 1.0) advisor covering all four functions: GOVERN, MAP, MEASURE, MANAGE. Use this skill whenever a user asks about NIST AI RMF, AI risk management, AI trustworthiness, GOVERN function, MAP function, MEASURE function, MANAGE function, AI RMF Playbook, AI risk profiles, responsible AI, AI bias management, AI transparency, AI explainability, AI reliability, AI safety, NIST AI 100-1, AI risk assessment, AI incident response, or alignment to EU AI Act, ISO 42001, or NIST CSF via AI RMF. Trigger even if the user doesn't say "skill" — any NIST AI RMF or AI governance risk question should use this skill.
Persistent Obsidian-based memory for coding agents. Use at session start to orient from a knowledge vault, during work to look up architecture/component/pattern notes, and when discoveries are made to write them back. Activate when the user mentions obsidian memory, obsidian vault, obsidian notes, or /obs commands. Provides commands: init, analyze, recap, project, note, todo, lookup, relate.
When the user wants to optimize post-signup onboarding, user activation, first-run experience, or time-to-value. Also use when the user mentions "onboarding flow," "activation rate," "user activation," "first-run experience," "empty states," "onboarding checklist," "aha moment," or "new user experience." For signup/registration optimization, see signup-flow-cro. For ongoing email sequences, see email-sequence.
Use when the user asks to install, configure, verify, troubleshoot, or understand OpenPets; install or select a pet; connect Claude Code, OpenCode, Cursor, Codex, or MCP clients; configure a project to use a specific pet; or debug openpets_status, openpets_react, or openpets_say.
Debug and inspect PostHog implementations on any website. Use this skill when a user wants to understand how PostHog is implemented on a page, troubleshoot tracking issues, verify configuration, check what events are being sent, or audit a PostHog setup. Works with Chrome DevTools MCP and Playwright MCP to inspect live websites.
Analyzes and improves prompts using 31 frameworks across 7 intent categories. Use when a user wants to improve, rewrite, structure, or engineer a prompt—including requests like “help me write a better prompt,” “improve this prompt,” “what framework should I use,” “make this prompt more effective,” or any prompt engineering task. Recommends the right framework based on intent (create, transform, reason, critique, recover, clarify, agentic), asks targeted questions, and delivers a structured, high-quality result
Research, create, improve, migrate, evaluate, package, install-check, govern, and safely publish qiaomu-flavored agent skills from workflows, prompts, transcripts, docs, SOPs, runbooks, scripts, or notes. Use for new or existing skills, prior-art synthesis, routing/trigger boundaries, trigger or output evals, Skill IR, release gates, README/Profile preparation, GitHub repository and pull-request publication, versioned Releases, clean npx installation, team reuse, and create-and-publish flows. The publication path is self-contained and forbids direct default-branch pushes. Exclude one-off summaries, translations, ordinary docs, non-skill package publishing, and tasks that explicitly should not become a skill.
Code improvement workflow with polish and overhaul tracks. Triggers: 'refactor', 'clean up', 'restructure', 'reorganize', or /refactor. Phases: explore, brief, implement, validate. Existing code only — Do NOT use for bug fixes (/debug) or new features (/ideate).
How to link to pages in the RevenueCat dashboard (offerings, products, customers, settings, integrations, paywalls, experiments, etc.). For chart links with filters, use revenuecat-charts; for filtered customer lists, use revenuecat-audiences.
Run a Gradle project's tests by test type or module — unit, integration, or all. Use this skill whenever the user wants to run, re-run, or check the project's tests (e.g. "run the unit tests", "run all tests", "run the integration tests for the vet module", "did the tests pass?").
Shepherd PRs through CI and reviews to merge readiness. Operates as an iteration loop within the synthesize phase (not a separate HSM phase). Uses assess_stack to check PR health, fix failures, and request approval. Triggers: 'shepherd', 'tend PRs', 'check CI', or /shepherd.
Create new skills, modify and improve existing skills, and measure skill performance. Use when users want to create a skill from scratch, update or optimize an existing skill, run evals to test a skill, benchmark skill performance with variance analysis, or optimize a skill's description for better triggering accuracy.
Create resizable, multi-pane layouts with Syncfusion Angular Splitter. Use this skill whenever the user wants to build split-pane interfaces, create dashboard layouts, implement sidebar+content patterns, or manage dynamic pane structures. Include scenarios involving horizontal/vertical splitting, collapsible panes, pane resizing, dynamic pane addition/removal, or complex nested layouts. Perfect for creating flexible UI layouts that adapt to user interaction.
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.
