All
Use when user requests diagrams, flowcharts, architecture charts, or visualizations. Also use proactively when explaining systems with 3+ components, complex data flows, or relationships that benefit from visual representation. Generates .tldr JSON files and exports to PNG/SVG locally using @kitschpatrol/tldraw-cli
Cut token usage across the whole session without losing correctness or substance — concise user replies, lean tests/docs/plans/comments, tight code, disciplined context and tool use, and cheap sub-agent delegation. Load when the user wants less verbosity, lower cost, fewer tokens, or a "token diet" / "lean mode"; also triggered by /token-diet or "token diet on".
When the user wants to add, fix, or optimize schema markup and structured data on their site. Also use when the user mentions "schema markup," "structured data," "JSON-LD," "rich snippets," "schema.org," "FAQ schema," "product schema," "review schema," or "breadcrumb schema." For broader SEO issues, see review-seo-audit.
Tool lifecycle UI components for React/Next.js from ui.inference.sh. Display tool calls: pending, progress, approval required, results. Capabilities: tool status, progress indicators, approval flows, results display. Use for: showing agent tool calls, human-in-the-loop approvals, tool output. Triggers: tool ui, tool calls, tool status, tool approval, tool results, agent tools, mcp tools ui, function calling ui, tool lifecycle, tool pending
Teach any topic deeply from first principles and build evidence-based paths toward exceptional capability. Use when a user asks to understand, explain, learn, or deep-dive into a topic; asks why or how something works, why it matters, how alternatives compare, or what different perspectives reveal; requests current paradigms, a complete roadmap or curriculum, deliberate practice and feedback, or a top-1%-level mastery plan. Answer explanation questions completely before offering a curriculum; route explicit mastery goals to an adaptive practice and proof-of-capability system.
Code quality guide based on 토스 Frontend Fundamentals. Provides feedback by 4 criteria (readability, predictability, cohesion, coupling) during code review, writing new code, and refactoring. Activates on requests about frontend code quality, clean code, or code improvement.
Run five independent max-effort reviews (Fable 5.1, Opus 5.5, GPT-6 Astra, GPT-6.1 Sol, Muse Wonder), merge their findings, and fix only what the user approves. Manual only: run when a human types /total-review; agents must never invoke it on their own.
Triage a UI Verify build from your coding agent via the UI Verify MCP: classify changed stories as real regressions, cosmetic reflows, or rendering noise; summarize real regressions for a PR comment; and accept baselines in bulk. Use after a UI Verify build reports changes when you want the agent to review, summarize, or accept them from the terminal instead of clicking through the dashboard. Triggers: “triage this build,” “summarize the visual regressions,” “accept all the new baselines.”
JS/TS style guidelines and review checklist for workerd. Covers TypeScript strictness, import conventions, export patterns, private field syntax, error handling, feature gating, and test structure. Load this skill when reviewing or writing JavaScript or TypeScript code in src/node/, src/cloudflare/, or JS/TS test files under src/workerd/.

Build stateless MCP servers with TypeScript on Cloudflare Workers using @modelcontextprotocol/sdk. Provides patterns for tools, resources, prompts, and authentication (API keys, OAuth, Zero Trust). Use when exposing APIs to LLMs, integrating Cloudflare services (D1, KV, R2, Vectorize), or troubleshooting export syntax errors, unclosed transport leaks, or CORS misconfigurations.
Use when checking which TYPO3 versions an extension says it supports, when composer.json and ext_emconf.php disagree, when a version bump has left some of the files that state it behind, when reviewing a TYPO3 extension for what needs attention, or when auditing coding standards, TER readiness, deprecations and modernization to v12/v13/v14 (v14.3 LTS is the default). Raising an extension to a newer TYPO3 version is not this skill: that belongs to typo3-extension-upgrade.
Control a PreSonus StudioLive Series III mixer from the command line. Trigger when the user asks about ucmix, a StudioLive / 32R / UCNET mixer, setting channel names/patches/48V/faders/mutes, monitor (aux) mixes, limiters, FX/reverb, stereo links, colors/icons, scenes, board-as-code (verify/apply a config), or reading/writing any mixer parameter.
Create beautiful, accessible user interfaces with shadcn/ui components (built on Radix UI + Tailwind), Tailwind CSS utility-first styling, and canvas-based visual designs. Use when building user interfaces, implementing design systems, creating responsive layouts, adding accessible components (dialogs, dropdowns, forms, tables), customizing themes and colors, implementing dark mode, generating visual designs and posters, or establishing consistent styling patterns across applications.
UiPath Maestro Case Management build work: always invoke for `caseplan.case` or `caseplan.json` (Studio Web also: `case.stage.json`, `default.stage.json`), `sdd.md`, or building/creating a case when no SDD exists yet (the case design is produced first, then confirmed in one review). Resolves tenant resources then authors or edits caseplan.case directly with Write/Edit. For .xaml → uipath-rpa, .flow → uipath-maestro-flow, .bpmn → uipath-maestro-bpmn. For standalone case SDD design, case `sdd.draft.md` finalization, PDD → SDD, or cross-product planning → uipath-planner.
UiPath Maestro Flow, UiPath Flow, and Maestro Automate (`.flow` / `.flow.ts` files): build, edit, run, debug, fix, or evaluate a flow. Author with the TypeScript builder SDK (`@uipath/maestro-builder-sdk`): nodes, triggers, schedules, connectors, document extraction (published IXP models, or the Extract document node with an inline taxonomy), inline agents, HITL, chat/voice flows, bindings, brownfield edits, and the check/compile/validate loop. Operate: upload, publish, deploy, debug a real run, trigger a process, check job status/traces, pause/resume/cancel/retry an instance. Diagnose faulted runs, incidents, runtime variables, and why validation passed but the run failed. Evaluate eval sets, evaluators, simulations, and eval runs. Case plans (`caseplan.case` / `caseplan.json`) → uipath-maestro-case; BPMN (`.bpmn`, `.bpmn.ts`) → uipath-maestro-bpmn. For raw IXP labeling or prompt tuning outside a Flow → uipath-ixp; standalone agents → uipath-agents; C#/XAML → uipath-rpa.
This skill MUST be used for evidence-grounded reasoning when the user requests ultrathink, 深度思考, or 深入思考. It SHOULD be used when substantive uncertainty or trade-offs remain, including questions of meaning, tone, or reader interpretation. Unless explicitly requested, it MUST NOT be used for routine work with no substantive uncertainty or trade-offs.
Inspect Underworld Overseer JSON saves and generate or troubleshoot interactive dungeon maps with RobThePCGuy/Underworld-Overseer-Save-Mapper. Use when a user wants to validate a save's Map records, visualize room coordinates and DescriptorID values, install the mapper, or diagnose empty/broken HTML output. Triggers on: Underworld Overseer save, dungeon save map, DescriptorID, Map JSON, Underworld Overseer mapper, or save-to-HTML.
Automatically rig 3D models with UniRig (VAST-AI-Research, SIGGRAPH'25) — predict a skeleton, predict skinning weights, and merge the rig back onto the original mesh. Use when the user wants auto-rigging for .obj/.fbx/.glb/.gltf/.dae/.vrm assets, a skeleton or skin weights for a character or creature, a UniRig environment prepared on a CUDA machine, batch rigging of a model directory, or an honest comparison between UniRig, SkinTokens, Tripo, Mixamo, AccuRig, and Blender Rigify. Triggers on: unirig, auto rig, auto-rigging, 3D rigging, skeleton prediction, skinning weights, rig a character, armature generation, rigged glb, rigged fbx, bone weights.
Create custom tools for the Unity editor: custom inspectors, tool windows, drawers, menu items, wizards and asset processors. Triggers: /unity-editor-tools, /editor, 'custom inspector', 'editor window', 'property drawer', 'menu item', 'editor tool', 'outil editeur'. Produces C# scripts in the Editor folder with the correct assembly definition.
Track and analyze US government shutdown liquidity impacts by monitoring TGA (Treasury General Account), bank reserves, EFFR, and SOFR data from FRED API. Use when user wants to (1) analyze current or past government shutdown effects on financial markets, (2) track liquidity conditions during fiscal policy disruptions, (3) assess "stealth tightening" effects, (4) compare shutdown episodes across different monetary policy regimes (QE vs QT), or (5) generate liquidity stress reports with historical context. Recommended usage frequency is weekly on Wednesdays after TGA/reserve data releases.
Load saved Playwright storageState authentication profiles before browser automation. Activates when `.playwright/profiles.json` exists and browser work begins on authenticated pages. Trigger phrases include "use profile", "load profile", "browser as [role]", "authenticated browser", "logged in browser session".
UX research and design toolkit for Senior UX Designer/Researcher including data-driven persona generation, journey mapping, usability testing frameworks, and research synthesis. Use for user research, persona creation, journey mapping, and design validation.
Run an honest market-fit and viability audit of any project or idea and produce a decision doc, not code. Use when someone asks "is this viable as a business", "audit the market fit", "make the case and compare to competitors", "should I apply to YC or bootstrap", or wants to validate a project, product, or market before investing more time. Gathers verifiable traction data first, researches the competitive field, gets an independent cold read, writes a doc with pre-committed pass/middle/kill criteria and a concrete week-1 assignment, then hardens it with an adversarial review loop.
Access comprehensive LaTeX templates, formatting requirements, and submission guidelines for major scientific publication venues (Nature, Science, PLOS, IEEE, ACM), academic conferences (NeurIPS, ICML, CVPR, CHI), research posters, and grant proposals (NSF, NIH, DOE, DARPA). This skill should be used when preparing manuscripts for journal submission, conference papers, research posters, or grant proposals and need venue-specific formatting requirements and templates.
Feature flags, A/B tests, and gradual rollouts with Vercel Flags, in any app or framework. Use whenever the user is planning, adding, changing, or cleaning up a feature flag, toggle, kill switch, experiment, percentage rollout, or targeting rule, or wants to gate or hide a feature for some users, even before a library or provider is chosen. Covers choosing an integration (Flags SDK, `@vercel/flags-core`, OpenFeature), the Vercel dashboard, the `vercel flags` CLI (create, inspect, set, split, rollout, rules, segments, evaluations, archive, connections), Project Connections, OIDC vs SDK keys, `FLAGS_SECRET`, and Flags Explorer overrides. For `flag()` declarations, adapters, precompute, and the Flags Explorer endpoint in Next.js or SvelteKit code, load the `flags-sdk` skill.
Run comprehensive triage-first verification pipeline with specialized skills. Detects scope, discovers toolchain, triages files to relevant skills, runs static analysis, invokes review skills in parallel, exercises the app, and produces a unified report. By default it then fixes the findings it judges worth fixing; report-only mode stops at the report.
Create or update repo-native project instructions for AI agents, such as AGENTS.md or CLAUDE.md. Use when initializing an AI-native repository protocol, documenting project overview, tech stack, repository structure, build/run/test commands, durable working rules, progressive disclosure, workflow artifact routing, organization skill routing, or converting repeated coding-session habits into durable agent instructions.
Diagnose and transform any authorized video URL, upload, recording, transcript, podcast, interview, presentation, screen recording, webinar, ad, or published video into the strongest justified content portfolio. Use for video audits, format recommendations, long-form editing, mid-form explainers, Shorts and Reels, teasers, tutorials, case studies, paid cutdowns, captions, packaging, delivery, or publication preparation.
Get finished MP4 videos ready to post, without touching a single slider.

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.
