Skills
96,770 packaged capabilities and playbooks for agents. Install any of them with one command.
All
Close out a work session — capture what was learned into memory, bring GitHub issues, the board, human follow-ups and docs up to date, and clean the local workspace. Use when the user says "end session", "wrap up" or "done for the day", or when the handoff skill reaches its end-session step.
Builds production-quality, accessible, responsive user-facing UIs. Use when building or modifying interfaces and pages, creating components, implementing layouts, meeting WCAG accessibility requirements, managing state, or when the output needs to look and feel production-quality rather than AI-generated.
Respond from a Montessori perspective—observation first, respect for the child, and the environment as teacher. Use when the user explicitly requests this perspective, mentions “montessori-perspective,” or wants to apply its core approach to analyze a problem; do not trigger automatically for general questions.
Create a music video for a song with code (no video-generation model needed): first understand the song (lyric timeline, beat, emotional arc, and how others interpret it), then choose an art style, draw characters, write the script and storyboard, sketch before producing the full video, and finally review and revise it using a checklist. You can also analyze the style of a reference video and reproduce it. Draw frames with Canvas / p5.js / p5.brush, and combine the lyrics and song with HyperFrames. Use when the user asks to make a music video, lyric video, or animated MV for a song, imitate a video's style for an MV, or says “make a music video / lyric video for this song.” Model-agnostic; any agent that can read and write files and run commands can follow it.
Use when turning a reference video into 3D character animation through the Scenario MCP: markerless motion capture from a phone clip or a generated performance, auto-rigging an uploaded FBX, GLB, or OBJ character and applying the captured motion, raw motion on a Mixamo or MetaHuman skeleton to retarget yourself, in-place locomotion, looping clips, facial capture, or FBX exports for Blender, Maya, Unreal, Unity, or Roblox. Keywords: mocap, video to motion, video23d, animation from video.
Hardens code against vulnerabilities. Use when auditing an input handler for vulnerabilities, when handling user input, authentication, data storage, or external integrations, or when checking a login flow is safe against the OWASP Top Ten. Use when building any feature that accepts untrusted data, manages user sessions, or interacts with third-party services. Use when auditing dependencies for known vulnerabilities, triaging package-manager audit findings, or assessing supply-chain risk in a new package. Use when personal data or privacy compliance (GDPR, CCPA) is involved.
Ship the current branch — evaluate its SemVer release impact, refresh the docs, write the changelog entry for the version this merge will mint, file its human follow-ups, run the fast checks, push, and open or update the PR. Use when a feature branch is ready for review, or when the user says "ship it", "open a PR", or "push this".
Startup growth consulting agent specializing in Product Hunt launches, open-source marketing, and Go-to-Market audits. Get expert-level strategic reviews and actionable recommendations. By @WeiYipei — fractional growth lead for AI startups
AI HOT (aihot.virxact.com) Chinese AI news query Skill. Use when users ask about today's AI news, an AI daily briefing, AI HOT, recent AI, recent releases from OpenAI/Anthropic/Google, AI industry updates, new LLM releases, selected stories, recent AI papers, AI product launches, AI tips and opinions, or any other Chinese-language AI news query. Trigger this Skill even if the user only says “AI scene,” “AI news,” or “AI daily briefing,” or asks “what happened today” in an AI / LLM / startup context. The Skill fetches data directly from the public REST API with curl and organizes it into a Chinese markdown briefing; users do not need to configure any API Key or MCP server. Do not undertrigger—if the user asks for AI news and you do not call this Skill, you are presenting outdated training data as today's news, which is harmful to the user.
Find the events and person properties that correlate with funnel conversion or drop-off. Use when the user asks why people convert or drop off in a funnel, what converters do differently, which events or properties predict success or failure, or asks for "correlation analysis" on a funnel. Computes odds ratios with HogQL, because PostHog has no built-in funnel correlation view.
Builds or changes an Apigee X proxy that acts as an AI or LLM gateway. Use it to route between models with aliases, or to add token quotas, spending budgets, Model Armor prompt and response inspection, prompt-token burst limits or FAQ semantic caching.
Turns a PRD into User Stories that a developer - human or agent - can build without guesswork: one User Story per in-scope feature, in As a/I want/So that format with at least two Gherkin scenarios, PRD conflicts documented rather than silently resolved, and open points stated as exact questions for the business. Use when the BA role receives a PRD, or when asked to write, draft or split user stories from a PRD, in any domain
Builds bespoke motion graphics for an edit, one animated clip per beat (HyperFrames + GSAP), each designed for its line and landing on the spoken word, then lays them on the footage through the style-edit render. Picks the beats that need motion (a count, a list, a flow, a before and after, a run, a mechanism), writes a brief per clip, runs one clip-builder agent per clip at once, gates every clip (lint, layout, render, a frame-to-frame motion check, contact sheets), and falls back to the template card for a clip that fails. Use when the user says "animation", "motion graphic", "animate this", "animate the part where I say X", "make a clip for", "build the animations", or when style-edit or visual-prep reaches the beats that need motion. Not for captions or zooms (style-edit), not for real screenshots and logos alone (overlays), not for a product demo film (product-video).
Add a licensed soundtrack to any video for $0 with beat-matched music, Openverse sound effects, -16 LUFS mastering, and FFmpeg verification. Searches 5.2M free CC0/CC-BY/public-domain audio files (no API key), aligns cuts to the kick-drum beat grid with librosa, peak-normalizes SFX one-shots, verifies the exported MP4 with ebur128 and cue frame grabs, and auto-writes credits.txt. Trigger when the user says "add sound to this video", "add music to my video", "add sound effects", "find free SFX", "sound design this clip", "my video needs audio", or "add audio to my ad".
Write the release notes for a Playwright release - the Node.js notes in docs/src/release-notes-js.md together with the Python, Java and .NET translations, and the GitHub markdown for each language's release. Use when asked to write, translate or publish release notes
Address the maintainers' review comments on a draft PR that the Issue triage workflow opened, unattended inside the PR revision GitHub Actions workflow (.github/workflows/revision.yml), which a needs-revision, needs-revision-mac or needs-revision-win label on the PR starts. Changes the code as the comments ask, verifies it on the runner, and leaves one commit for the workflow to push to the same PR. Only for that workflow.
Find, inspect and control processes and ports with the proc CLI (macOS, Linux, Windows), with JSON output for agents. Use it instead of lsof, ps, pgrep, pkill, kill, netstat, pstree or top whenever you need to: see what is on a port or free it (EADDRINUSE, "address already in use", a dev server that won't start); find processes by name, PID, file or project directory; inspect a process (command, cwd, parent, uptime, CPU, memory); stop, kill, pause, resume or wait for processes; trace why a port is busy; find orphaned, stuck or leftover processes, such as dev servers, watchers and headless browsers that you or another agent started; or clean up background work before finishing a task. Also use when the user mentions proc, ports, PIDs, signals (SIGTERM, SIGKILL, SIGSTOP) or a slow machine
Use when the user asks to confirm feature trade-offs in a PRD or development plan item by item; not for quality reviews, writing documents from scratch, or implementation. Briefly explain each feature, its value, and the planned approach; revise the document after confirmation, rejection, or changes
Cut clips and highlights from a video. Use when the user wants a clip of a time range, a highlight reel of the moments that match a prompt ("every product demo", "the goals in this match"), a supercut across several videos, a vertical or square cut for Shorts, Reels or TikTok, a thumbnail, or an MP4 to download. One moment found by what was said is video-search, which also cuts that clip; joining whole videos with transitions is video-edit. Works on YouTube links, public URLs and the user's VideoDB videos.
Build interactive games using Augmented Reality (AR) and camera-based motion and gesture tracking for Smart TVs, Interactive Flat Panels (IFP), digital whiteboards, or laptop webcams. Students can interact at the front of the classroom without touching a physical screen.
Cut a Semantic Versioning release in any repository: find the version source, decide MAJOR, MINOR or PATCH from the commits since the last tag, update the manifest, the changelog and any current-release line, then commit and create an annotated tag, leaving the push to the user. Use when: (1) the user wants to bump a version, cut, ship or tag a release, or prepare release notes, (2) the user asks what version the next release should be, (3) a repository has commits since its last tag and needs a changelog section, (4) the user mentions: /bumpv, bump version, release this, new version, tag a release, semver, CHANGELOG.md, Keep a Changelog, chore(release), git describe, annotated tag, --follow-tags, package.json version, Cargo.toml, pyproject.toml, "what version should this be". Carries a version-source table for Node, Rust, Python, Go, PHP, Ruby, .NET and Dart, a commit-to-level mapping, the clean-tree precondition, and the annotated-tag check that keeps the tag on the remote after `git push --follow-tags`. Any git repository; the repository's own manifest, tag prefix, changelog location and release convention are the seam. Not a publisher: it never pushes, never creates a GitHub Release and never runs a package registry publish, and it versions one package, not a monorepo workspace
Install, set up and use the tailwindcss-concentric plugin to fix and prevent mismatched nested corner radii in Tailwind CSS v4 projects. Use when the user asks to add or set up tailwindcss-concentric, to audit or fix nested border radii, or when building or reviewing UI where a rounded element sits inside a padded or bordered rounded parent (cards with media, buttons in search bars or toolbars, segmented controls, selection rings, modals, input groups), when you see hard-coded inner radii such as rounded-[calc(...)], or when the user mentions concentric, nested, inner or outer corner radius
Contextualizes the business of an existing system (brownfield) for AI-first work: builds the capability map (what the system does today), surfaces business rules hidden in code, and creates the business ↔ code glossary with the ARCH, all with evidence, then pauses for human approval. Use when the BA role starts on an existing system without a PRD or backlog, or when asked to document what a legacy system does, extract its business rules, or build a domain glossary
Contextualizes an existing repository (brownfield) for AI-first work on it: verifies how to start and test it, creates the CodeGraph index, reconstructs the actual layer map, documents inherited decisions as ADRs, assembles the pattern catalog (canon vs. legacy), the debt map and verifiable build rules, all with file:line evidence, then pauses for human approval. Use when the ARCH role starts on an existing codebase without a PRD, or when asked to contextualize, onboard, document, map or understand a legacy/brownfield repository before working on it
Find the mistakes agents keep repeating in this repo and make each one impossible. Try architecture first, then types, then a lint whose error names the fix, then a test, and write docs last. Prove each check fails on a real past mistake. Repeat this each time the operator corrects you. Use for /correct.
End-to-end Course & Class Management coordinator. Guides teachers, lecturers, and instructors from RPS/RPP analysis, teaching module creation, tiered exercises, 16:9 slides, web and AR gamification, automated assignment assessment, OBE dashboards, portfolio reporting, through to textbook connections.
Design and create interactive, web-based educational mini-games (HTML5 Canvas/JS/CSS) for each lesson. Turn teaching topics into concept-sorting games, logic puzzles, quick-guess arenas, branching scenario simulations, or crosswords playable in desktop or mobile browsers.
Debugs issues users encounter with Tuist-generated projects by reproducing the scenario locally, building Tuist from source when needed, and triaging whether it is a bug, misconfiguration, or something that needs team input. Use when users report generation failures, build errors after generation, or unexpected project behavior.
Builds a one-screen executive report dashboard for teachers and lecturers. Presents all key class indicators (assignment submission rate, average CPMK, grade distribution, alerts for students needing attention) with a responsive Mobile-View First design and strict credential security.
Use when the user asks to fix, patch or upgrade a Node.js vulnerability (e.g. 'Please fix my Node vulnerability'), the October 21, 2026 Node.js security release, CVE-2026-111497 (Brotli RCE), or end-of-life Node 20, across Docker images, .nvmrc/.tool-versions, setup-node CI, Lambda and IaC. Read-only inventory, approval gate, regression tests, focused PRs.
Guides day-to-day work in Tuist-generated Xcode workspaces, including generation, build and test commands, and buildable folders. Use when working in a Tuist-generated project or when users mention `tuist generate`, `xcodebuild test`, or generated workspaces.
Set up PostHog in a user's GitHub repository from a chat, without a terminal. Wizard, PostHog's setup agent, runs in the cloud, adds the SDK and first events, and opens a pull request. Use only when you can't read or edit the user's code, which is common in web chat apps such as ChatGPT on the web or Claude on the web. Typical requests: install, add, or set up PostHog in their app or repository, or open a pull request that adds PostHog. When you're working in the user's repository, use installing-posthog-in-a-codebase instead. Covers connecting GitHub, picking the repository, starting the run, polling it, and sharing the pull request.
Builds a professional Excel spreadsheet workbook (.xlsx) for calculating Outcome-Based Education (OBE) assessment fulfillment, mapping CPL and CPMK attainment per student, grade distribution matrices, and visualizing accreditation achievement charts.
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.
