Diagnose and fix a website on Hostinger web hosting (Shared, Cloud or Agency plans) that is down, slow, erroring, insecure or failing to build. Checks the site from outside, reads builds, runtime logs, WordPress health, SSL, cache and PHP settings through the Hostinger MCP, names the cause with evidence, and applies the fix once the user agrees. Triggers: my site is down, site not loading, 500 / 502 / 503 error, white screen, error establishing a database connection, site is slow, SSL or certificate warning, not secure, changes not showing, Node.js build failed, app keeps crashing
typescript-eslint - ESLint plugin for TypeScript. USE WHEN: user mentions "typescript-eslint", "TypeScript linting", "type-aware rules", asks about "no-floating-promises", "TypeScript ESLint config", "@typescript-eslint rules". DO NOT USE FOR: ESLint 9 full setup - use `eslint-biome` skill, Biome - use `eslint-biome`, general quality - use `quality-common`

Integrates uCharts data visualization into UniApp projects including easycom configuration, pages.json and manifest.json setup, platform-specific handling (H5, mini-program, App, nvue), and chart lifecycle management. Use when the user needs to add charts to a UniApp project, configure uCharts components, or handle cross-platform chart rendering.
Unity data-driven design architecture. ScriptableObject config hierarchies, JSON data pipelines, designer handoff workflows, data versioning and migration, Inspector attributes for self-documenting configs. DECISION format: WHEN/DECISION/SCAFFOLD/GOTCHA. Based on Unity 6.3 LTS.
Unity 6 editor scripting and custom tools guide. Use when creating custom inspectors, EditorWindows, PropertyDrawers, Gizmos, Handles, menu items, or editor extensions. Covers SerializedObject/SerializedProperty pattern, AssetDatabase, and editor-only code with #if UNITY_EDITOR. Based on Unity 6.3 LTS documentation.
Analyzes market breadth using Monty's Uptrend Ratio Dashboard data to diagnose the current market environment. Generates a 0–100 composite score from 5 components (breadth, sector participation, rotation, momentum, historical context). Use when asking about market breadth, uptrend ratios, or whether the market environment supports equity exposure. No API key required
Use when Codex is already in the validation phase of a security scan or the user explicitly asks to determine whether one or more candidate security findings are valid. Do not use as the primary trigger for full PR, commit, branch, patch, or repository scans.
Verify test cases in all test files modified since branching out from base branch. Checks that test cases make sense, have no duplications, and provide meaningful coverage. Spawns parallel agents for multi-file analysis. After the user confirms test-case changes, runs coverage (npm test:coverage or Jest/Vitest fallback) and fixes tests until coverage passes.
Use this skill when reviewing or changing an existing Vite + TanStack Router project architecture, especially routes, loaders, validateSearch, services, hooks, Vite/TanStack Router platform setup, and nested shared folders such as src/lib or src/services. Do not use for TanStack Start or generic Vite apps without TanStack Router.
Comprehensive vitest testing patterns covering test structure, AAA pattern, parameterized tests, assertions, mocking, test doubles, error handling, async testing, and performance optimization. Use when writing, reviewing, or refactoring vitest tests, or when user mentions vitest, testing, TDD, test coverage, mocking, assertions, or test files (*.test.ts, *.spec.ts).
Generate accurate Volcengine SDK examples by locating an API through API Explorer search, fetching its swagger, and calling api/common/explorer/make-code with user-provided Params. Use when the user asks how to write Volcengine SDK code, generate SDK samples, or call a Volcengine API in Python, Go, Java, PHP, cURL, Node.js. Supports Chinese and English API names such as "角色扮演", "AssumeRole", or "STS AssumeRole". Also use for explicit SDK configuration questions about retry, timeout, AK/SK, STS, AssumeRole, temporary credentials, proxy, connection pooling, SSL, debug mode, request signing, response parsing, and error handling. If the user only needs API parameters, enum values, required fields, error codes, response schemas, pagination, or API comparisons, hand off to volcengine-api. If they need CLI-based operations, hand off to volcengine-cli.
Design navigation and information architecture for cognitive accessibility. Use when designing or reviewing navigation, site maps, page hierarchies, breadcrumbs, search, multi-step flows, or any structure where users need to find content and know where they are. Triggers on: users get lost, navigation, wayfinding, information architecture, breadcrumbs, findability, site map, confusing structure, where am I.
Fix PageSpeed Insights/Lighthouse accessibility "!" errors caused by contrast audit failures (CSS filters, OKLCH/OKLAB, low opacity, gradient text, image backgrounds). Use for accessibility-driven SEO/performance debugging and remediation.
Automatically publish HTML articles to the WeChat Official Account drafts folder, with cover image upload and title, author and metadata management. Use when the user says "推送到微信", "发布到公众号草稿", "上传到草稿箱", or mentions publishing WeChat articles.
Generate an interactive bash wizard that guides a human through steps only they can perform. Suitable for configuring infrastructure, setting up credentials or CI secrets, working with unfamiliar third-party panels, or performing one-off migrations or switches. Do not let the agent perform on its own the steps that a human should complete.
How to work in a Worldbuilding project (the `worldbuilding` starter pack): a fiction encyclopedia of characters, settings, themes, factions, and lore. Read when the project has these folders, OR when asked to add a character, setting, faction, or piece of lore, or to check the world for internal consistency. Carries the auto-stub and consistency behaviors so that guidance does not live inside template bodies or folder descriptions. Complements the platform `open-knowledge` skill; does not replace it.
For personal writing, including coming up with new articles from scratch and reviewing or polishing existing ones. Use it immediately when the user shares an article and asks for feedback, wants to improve their writing style, does not know what to write, needs to organize a travelogue, TIL, or personal essay, or asks for a check of Chinese quality. Trigger words include 「帮我改文章」「检查一下」「润色」「校对」「不知道写什么」「帮我构思」「写游记」「记录 TIL」「写点什么」. Not for formal business communication.
Publish tweets and threads to X (Twitter) draft using browser automation. Use when user wants to publish content to X, save to drafts, or mentions "publish to X", "post tweet", "x-publish", "发布推文". Supports short tweets and threads. NEVER auto-publish, always saves to draft.
Use when the user needs Excel file manipulation — reading, writing, formulas, charts, conditional formatting, data validation, pivot tables, or large file handling. Trigger conditions: create Excel reports programmatically, read spreadsheet data, add formulas or charts, apply conditional formatting, perform data validation, generate pivot tables, handle CSV import/export, process large datasets in Excel format.
Write distinctive Xiaohongshu copy for fitness coaches to attract local, in-person members. Use when the user has a specific member problem, chosen angle, or existing draft, has provided their activated personal DNA, and wants a post written or revised. Not for brainstorming broad topics such as “weight loss” or teaching other coaches how to acquire clients
Build personal DNA for fitness coaches serving local, in-person members. Use for an initial profile, organizing information from voice input, continuing an interview, or updating personal details. Present six groups of questions at a time and organize business and venue strengths, core audience pain points, real client concerns, identity and service delivery, standout cases, and reasons clients choose them. After confirmation, the profile can be reused by content skills. For existing profiles, fill only relevant gaps; do not require starting over. Does not write copy directly.
Save any URL to your YouMind board with one command — instant web clipper for articles, videos, and documents. Works from terminal, CI/CD, and any agent platform. Use when user wants to "save link", "bookmark", "clip", "web clipper", "save URL", "save page".

Replace an existing agent's hand-written routing (keyword if/else chains, regex, or an LLM call that only picks a route) with a Redis Iris Intent Router through redis-iris, so a message maps to a defined intent and its dispatch target by example phrasings and a score threshold. Asks five questions (what the routes are today, a few real phrasings per route, what each route dispatches to, what happens when nothing matches, which embedding model), writes the answers to intents.yaml, provisions the Router from the terminal with `iris intent-router service create`, loads the intents with `iris intent-router intents add`, then wires `router.match()` where the agent decides today. Use when the agent routes with keywords or an extra LLM call, or the user asks for intent detection, intent routing, or semantic routing.
Attack a PR or passing test suite in a fresh agent to find issues. Use when asked to “review this PR,” “attack this PR,” or “find what is wrong with this change” before a merge, or before trusting a passing test suite—especially for AI-written code with AI-written tests. Give the brief below to a separate agent with its own context so it does not share the author’s blind spots. Check the change against the acceptance criteria you provide and the repo’s CLAUDE.md or AGENTS.md. Prove each finding with a failing test where possible; report the rest as reasoned findings (file:line and the argument), clearly labeled so they are never mistaken for proved findings. Give a merge verdict; fix nothing. Works in any harness (a Claude Code subagent, Hermes delegate_task).
Coding Agent Session Search - unified CLI/TUI to index and search local coding agent history from Claude Code, Codex, Gemini, Cursor, Aider, ChatGPT, Cline, OpenCode, Amp, Pi-Agent, Factory, and more. Use when searching past agent conversations, indexing coding session history, finding previous solutions across agents, or querying session logs with CASS CLI robot mode.
Creates actionable alignment frameworks that give teams a shared North Star (direction), values (guardrails), and decision tenets (behavioral standards). Enables autonomous decision-making while maintaining organizational coherence. Use when starting new teams, scaling organizations, defining culture, establishing product vision, resolving misalignment, creating strategic clarity, or when user mentions North Star, team values, mission, principles, guardrails, decision framework, or cultural alignment.
Conducts comprehensive, systematic literature reviews across multiple academic databases (PubMed, arXiv, bioRxiv, Semantic Scholar), with PRISMA 2020 flow tracking, study screening (title/abstract and full-text), evidence-table extraction, and risk-of-bias assessment (RoB 2, ROBINS-I, AMSTAR 2), producing professionally formatted markdown documents and PDFs with verified citations in multiple styles (APA, Nature, Vancouver). Use when running a systematic or scoping literature review, research synthesis, or broad literature search, building a PRISMA flow diagram, screening studies, extracting an evidence table, or assessing risk of bias across biomedical, scientific, and technical domains. For quantitative pooling of effect sizes (forest/funnel plots) use alterlab-meta-analysis; for an open-ended multi-agent investigation, fact-check, or Socratic research-question work use alterlab-deep-research. Part of the AlterLab Academic Skills suite.
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.
