Explore MCP Servers & Agent Skills

io.github.novuhq/novu/ink-tui

Build terminal user interfaces (TUIs) using Ink (React for CLIs) and @inkjs/ui with a reactive, session-driven wizard pattern. Use when creating interactive CLI installation wizards, setup flows, or multi-step terminal applications in Node.js/TypeScript. Covers reactive screen resolution, declarative flow pipelines, overlay interrupts, session state management, Ink components, Flexbox terminal layout, and graceful degradation across terminal environments.

io.github.metabase/metabase/typescript-review

Review TypeScript and JavaScript code changes for compliance with Metabase coding standards, style violations, and code quality issues. Use when reviewing pull requests or diffs containing TypeScript/JavaScript code.

io.github.metabase/metabase/typescript-write

Write TypeScript and JavaScript code following Metabase coding standards and best practices. Use when developing or refactoring TypeScript/JavaScript code.

io.github.github/spec-kit/code-review

Reviews Spec Kit code changes for positive and negative test coverage, regression evidence for bug fixes, and consistent repository terminology. Use when reviewing a diff or pull request. Do not use for implementing changes or posting GitHub review actions.

io.github.tracer-cloud/opensre/tools

Read Yandex Cloud through its REST API. Applies to any question about VMs, metrics, logs, audit events, Kubernetes, managed databases, serverless, networking or any other Yandex Cloud resource. Never shell out to the `yc` CLI — it is not how this agent reaches Yandex Cloud and is usually not installed.

io.github.streamlit/streamlit/understanding-streamlit-architecture

Explains Streamlit's internal architecture including backend runtime, frontend rendering, and WebSocket communication. Use when debugging cross-layer issues, understanding how features work end-to-end, planning architectural changes, or onboarding to the codebase. Covers ForwardMsg/BackMsg protocol, script rerun model, element tree, widget state management, and more.

io.github.microsoft/vscode/ux-css-layout

VS Code CSS conventions, file organization, class naming, standard sizes, SplitView/Grid layout, scrollable content, responsive layout, and text overflow/ellipsis patterns. Use when writing CSS, building layouts, or fixing text truncation issues.

io.github.microsoft/vscode/customizations-in-the-agent-host

Architecture and hard-won debugging lessons for customization enablement (plugins, MCP servers, agents, skills, instructions) in the agent host. Use when changing how customizations are discovered, published, enabled/disabled, or handed to a provider SDK; when a customization shows the wrong enabled state in the UI; or when a disabled MCP server or plugin is still reaching the model.

io.github.microsoft/vscode/design-philosophy

The VS Code design philosophy — a shared Values→Principles→Moves vocabulary for reasoning about UI in design terms instead of raw pixels. Use when designing, building, reviewing, or giving feedback on any visual surface; when deciding a radius, spacing, type role, icon size, border, color, or motion; or when translating a "this feels off" observation into a concrete, principled fix.

io.github.discourse/discourse/discourse-frontend-conventions

Conventions for Discourse frontend code, JavaScript and TypeScript alike (.js/.gjs/.ts/.gts), in core, plugins, and themes, and how they split between what bin/lint enforces and what needs judgment. Use when writing, reviewing, or preparing to commit class-based code or templates. Covers the private-symbols pattern (#, unprefixed, _), the within-bucket member ordering the linter leaves open, the lint-enforced member order, blank lines and banner rules, attribute/argument/modifier ordering on invocations, and the comment necessity gate.

io.github.discourse/discourse/discourse-writing-typescript

Write TypeScript for Discourse core, plugins, and themes. Use when authoring new .ts/.gts files (components, modifiers, helpers, services, utils), typing an existing public API, or converting existing .js/.gjs files to .ts/.gts. Covers the component/modifier/plain-class Signature patterns, TSDoc for Signatures, typing untyped dependencies, compile-time type tests, the strict-grade bar under the loose global tsconfig, and the faithful-port and rename pitfalls that the type-checker does NOT catch.

io.github.mem0ai/mem0/mem0-integrate

Integrate Mem0 into an existing repository using a goal-driven, TDD pipeline. Detects the repo's language automatically and asks the user to pick between Mem0 Platform (managed) and Mem0 Open Source (self-hosted). Writes failing tests before any implementation. Produces a local feature branch plus `.mem0-integration/` artifacts consumed by the paired verification skill. TRIGGER when: user says "integrate mem0", "add mem0 to this repo", "wire mem0 into <repo>", or asks how to add memory to an existing project. DO NOT TRIGGER when: the user wants general SDK usage (use skill:mem0), CLI usage (use skill:mem0-cli), or Vercel AI SDK (use skill:mem0-vercel-ai-sdk). After success, invoke skill:mem0-test-integration to verify in the same workspace (loose coupling).

io.github.NousResearch/hermes-agent/reddit-reading

Read Reddit: subreddits, search, threads, users. No browser.

io.github.ToolJet/ToolJet/manage-skills

Add, move, or repair agent skills in this repo — decide public root vs private EE submodule placement and wire the symlinks so a skill is invokable from repo root in Claude Code, Cursor and Codex. Use when asked to add, create, move, relocate, or rename a skill, or when a skill is not showing up.

io.github.addyosmani/agent-skills/test-driven-development

Drives development with tests using the red-green-refactor loop. Use when implementing any logic, fixing any bug, or changing any behavior. Use when you need to prove that code works, when a bug report arrives, or when you're about to modify existing functionality.

io.github.addyosmani/agent-skills/doubt-driven-development

Subjects every non-trivial decision to a fresh-context adversarial review before it stands. Use when you want every assumption cross-examined before proceeding, when stress-testing a plan for hidden failure modes, when correctness matters more than speed, when working in unfamiliar code, when stakes are high (production auth, security-sensitive logic, a high-stakes migration, irreversible operations), or any time a confident output would be cheaper to verify now than to debug later.

io.github.addyosmani/agent-skills/shipping-and-launch

Prepares production launches. Use when preparing to deploy to production, or when asking what needs to be in place before shipping. Use when you need a pre-launch checklist, when setting up monitoring, when planning a staged rollout, or when you need a rollback strategy.

io.github.addyosmani/agent-skills/git-workflow-and-versioning

Structures git workflow practices. Use when making any code change. Use when committing, branching, resolving conflicts, splitting uncommitted work in a messy working tree into clean atomic commits, opening or reviewing a pull request (PR), pushing to a remote, or when you need to organize work across multiple parallel streams. Use when cutting a release, choosing a semantic version bump, tagging, or writing a changelog.

io.github.affaan-m/ECC/autonomous-agent-harness

Transform Claude Code into a fully autonomous agent system with persistent memory, scheduled operations, computer use, and task queuing. Replaces standalone agent frameworks (Hermes, AutoGPT) by leveraging Claude Code's native crons, dispatch, MCP tools, and memory. Use when the user wants continuous autonomous operation, scheduled tasks, or a self-directing agent loop.

io.github.browser-use/browser-use/cloud

Documentation reference for using Browser Use Cloud — the hosted API and SDK for browser automation. Use this skill whenever the user needs help with the Cloud REST API (v2, v3, or v4), browser-use-sdk (Python or TypeScript), X-Browser-Use-API-Key authentication, cloud sessions, browser profiles, profile sync, CDP WebSocket connections, stealth browsers, residential proxies, CAPTCHA handling, webhooks, workspaces, skills marketplace, liveUrl streaming, pricing, or integration patterns (chat UI, subagent, adding browser tools to existing agents). Also trigger for questions about n8n/Make/Zapier integration, Playwright/ Puppeteer/Selenium on cloud infrastructure, or 1Password vault integration. Do NOT use this for the open-source Python library (Agent, Browser, Tools config) — use the open-source skill instead.

io.github.bentoml/BentoML/bentoml-containerize

Build a local BentoML project into a Bento, containerize it into an OCI/Docker image, smoke-test it locally, and push it to a container registry (Docker Hub, GHCR, ECR, private registry, kind/minikube local load, or ttl.sh). Use when the user asks to "containerize a Bento", "build a Docker image for my BentoML service", "package my BentoML service for deployment", "push my Bento image to a registry", or as the first step of deploying BentoML to Kubernetes or EC2. Does NOT deploy anything itself — hand off to bentoml-k8s-deploy or bentoml-ec2-deploy for that.

io.github.nexu-io/open-design/last30days

Recent community and social trend research over the last 30 days. Use when the brief asks what people are saying now, recent sentiment, community reactions, social proof, launch reaction, trend scan, or last-30-days context.

io.github.android/skills/leanback-to-compose-tv-migration

Provides instructions and architectural patterns for migrating Android TV applications from legacy Leanback UI Toolkit, Android Views, or Support Fragments to Jetpack Compose for TV (androidx.tv). Use this skill for Leanback to Compose migrations, including browse screen, settings screen, authentication screen, login screen, or video playback screen migrations, or when replacing BrowseSupportFragment, LeanbackSettingsFragment, PreferenceFragment, BaseLeanbackPreferenceFragmentCompat, VideoSupportFragment, GuidedStepSupportFragment, SearchSupportFragment, VerticalGridSupportFragment, Presenter, ArrayObjectAdapter, or CursorMapper with modern Compose equivalents, implementing immersive carousels with focus memory, Media3 video playback with PlayerSurface, or custom 10-foot hero layouts.

io.github.lobehub/lobehub/debug-frontend-with-browser

Use for intermittent UI, stale state, ordering, navigation or browser-only bugs. Extends acceptance with boundary tracing and regression diagnosis.
