Use when grooming hair or fur in Blender with hair curves, such as a character hairstyle, animal fur, procedural fur in geometry nodes, or hair cards and mesh hair for games. Also covers the Essentials hair node assets (Interpolate, Clump, Curl, Frizz, Noise, Trim), density masks, bald spots, parting lines, strand shading in Cycles or EEVEE, and slow grooms. Use it too when a hair script misbehaves headless, for example stale modifier inputs or curve sculpt brushes that do nothing.
Guides authoring, reviewing, and validating agent skills (SKILL.md + metadata.json + references/ + scripts/) in this Capgo skills repository and similar ones. Covers trigger and negative-trigger design, lean SKILL.md with a when-to-load reference index, traps over basics, verification and error-handling sections, version tagging of facts, subagent-oriented skills (main-agent vs subagent split), optional when_to_use frontmatter, inline snapshots with allowed-tools, skillgrade evals, and this repo's canonical skills/ to plugins/ mirroring and registration. Use when creating a new skill, tightening a skill's description or triggers, splitting a long skill into references, or fixing `bun run lint-skills` failures. Do not use for app documentation, README or marketing copy, or library code that is not a skill.
This skill should be used when the user wants to add a service from a template, find templates for a specific use case, or deploy tools like Ghost, Strapi, n8n, Minio, Uptime Kuma, etc. For databases (Postgres, Redis, MySQL, MongoDB), prefer the database skill.
Master TypeScript's advanced type system including generics, conditional types, mapped types, template literals, and utility types for building type-safe applications. Use when implementing complex type logic, creating reusable type utilities, or ensuring compile-time type safety in TypeScript projects.

Use this skill when the user mentions "pinme", or needs to upload files, store to IPFS, create/publish/deploy websites or full-stack services (including frontend pages, backend APIs, database storage, email sending, etc.), or any feature requiring backend database/server support.
Use when turning a song, track, or audio master into a finished music video with Scenario and Seedance: planning shots against beats and sections, transcribing lyrics, generating clips that cut to music, keeping the shots' own sound while the song stays the only score, assembling a delivery over the untouched master soundtrack, or verifying the final cut. Keywords: music video, beat sync, shot list, lyric transcription, reference frames, ffmpeg assembly, Seedance.
Use when adding sound to a video or generating standalone audio with Sonilo models on Scenario via MCP: text-to-sound-effects, text-to-music, video-to-sound-effects or video-to-music from a clip, scoring silent AI video, foley, ambience, muxed video-to-video variants returning the clip with the new track mixed in, keeping speech while replacing music, or per-segment sound control.

Also use when debugging X6 rendering errors, v2→v3 migration, or editor interaction issues. Do NOT use for G2 statistical charts, G6 network graphs, or S2 pivot tables.
Drive Chrome via the DevTools Protocol from JavaScript. Run JS snippets through the `browser-harness-js` CLI — it auto-spawns a long-lived bun HTTP server holding a fully-typed CDP `Session`, and every call (`browser-harness-js 'await session.Page.navigate(...)'`) executes against the same persistent connection. Session, active target, and globals survive across calls. Use when the user wants to automate, script, or inspect a Chrome browser via CDP — single tab or multi-tab, attach to existing Chrome or to a new one launched with --remote-debugging-port.
Apple HIG guidance for navigation-related components including search fields, page controls, and path controls. Use this skill when the user says "how should search work in my app," "I need a breadcrumb," "how do I paginate content," or asks about search field, search bar, page control, path control, breadcrumb, navigation component, search UX, search suggestions, search scopes, paginated content navigation, or file path hierarchy display. Cross-references: hig-components-menus, hig-components-controls, hig-components-dialogs, hig-patterns.
Applies Eric Ries's Lean Startup methodology for building products under extreme uncertainty. Use when iterating toward product/market fit, designing MVPs, deciding whether to pivot or persevere, setting up actionable metrics, or accelerating the Build-Measure-Learn loop. Triggers include 'how do we test this idea fast', 'what should our MVP look like', 'our metrics look good but we're not growing', 'should we pivot', 'we're building features no one uses', 'how do we measure validated learning', 'vanity metrics vs real metrics', 'how to do innovation accounting'. NOT for companies with proven product/market fit scaling a known playbook (use Crossing the Chasm), not for determining Market Type (use Four Steps), not for sales methodology (use SPIN Selling), not for pricing strategy (use Monetizing Innovation).
Use when a Seedance video must hold continuous movement across shots: dance choreography, fights, sports, or any performance where limbs teleport, feet slide, or motion resets at every cut, or when turning a storyboard and character sheet into a multi-shot sequence that plays as one take. Keywords: storyboard to video, choreography, movement control, pose chain, timecoded shot script, first and last frame chaining, character sheet, multi-shot continuity, Seedance 2.5 and 2.0.
Use when a request prescribes a method, tool, metric, or artifact that may not reach the result the user described, or when doing the request as written would leave that result unproved: "A/B test the signup button color" for a conversion problem, "add a cache" for a slow page, "the focused tests passed, announce the release". Also use when a stated constraint contradicts itself, when an unknown fact would have to be invented to finish, or when an external or irreversible step needs an authorization decision. Keywords: right approach, wrong metric, root cause, outcome versus output, what counts as done, proof, is this worth doing. Not for a literal edit, format, translation, or lookup whose method is the deliverable. Not a replacement for the design, debugging, research, or writing method that performs the work. Use the reify skill instead when the request is still too vague to have any method or outcome yet.
Frontend development guidelines for React/TypeScript applications. Modern patterns including Suspense, lazy loading, useSuspenseQuery, file organization with features directory, MUI v7 styling, TanStack Router, performance optimization, and TypeScript best practices. Use when creating components, pages, features, fetching data, styling, routing, or working with frontend code.
Guide for implementing oRPC contract-first API patterns in Dify frontend. Trigger when creating or updating contracts in web/contract, wiring router composition, integrating TanStack Query with typed contracts, migrating legacy service calls to oRPC, or deciding whether to call queryOptions directly vs extracting a helper or use-* hook in web/service.
Diagnose and fix a hard bug. Build a reliable reproduction, name the cause, add a regression test, and apply the minimum fix. Use when the user reports a bug, a failure, a flaky test, a performance regression, an error, or a wrong result whose cause is unknown. Use when the user pastes a symptom, a stack trace, or failing test output. Use for "why is X broken", "it stopped working", "it got slower", or "this looks wrong". Do not use for a review-only diff, for feature design, or for a fix whose cause is known.
Read, create, fill, and transform PDF files. Covers extracting text and tables, OCR of scanned pages, filling fillable and flat forms, and flattening, merging, splitting, rotating, stamping and encrypting. Use when a task takes a .pdf as input or must produce one.

Use when a task involves running a Scenario workflow through MCP, including anything the user calls a Scenario app, a saved pipeline, or a multi-step generation graph. Triggers include listing workflows, building workflow_run's inputs object, pricing a run with a dry run, approving or rejecting a stuck approval node, a run rejected for input length, or a workflows_list reply flooding the context. Creating or editing graphs is scenario-workflow-authoring. Keywords: workflow, app, approval gate.
Execute a complete tax-loss harvesting workflow from candidate identification through post-harvest monitoring. Use when the user asks about finding TLH candidates, gain/loss budgeting, replacement security selection, wash-sale compliance, or harvest execution planning. Also trigger when users mention 'unrealized losses in my portfolio', 'swap ETFs for tax purposes', 'harvest losses before year-end', 'substantially identical security', 'wash-sale window', 'NIIT offset', 'loss carryforward', or ask how much tax they can save by harvesting.
Create a camera-correct sky background for a 3D scene with a procedural atmosphere or panorama, horizon haze, aligned sunlight, and coherent environment lighting. Use for architectural skies, outdoor 3D backgrounds, golden hour, and day-to-night sky transitions.
Apple HIG guidance for input methods and interaction patterns: gestures, Apple Pencil, keyboards, game controllers, pointers, Digital Crown, eye tracking, focus system, remotes, spatial interactions, gyroscope, accelerometer, and nearby interactions. Use when asked about: "gesture design", "Apple Pencil", "keyboard shortcuts", "game controller", "pointer support", "mouse support", "trackpad", "Digital Crown", "eye tracking", "visionOS input", "focus system", "remote control", "gyroscope", "spatial interaction".

Use when crafting ethical persuasion (marketing, sales, negotiation), defending against manipulation, or designing systems that need cooperation. Includes replication-crisis caveats and known factual corrections (Bickman parking-meter numbers, Hofling modern replication, Drive Carefully condition disambiguation, Genovese myth).
Assess investment suitability obligations under FINRA Rules 2111 and 2090 across all three suitability prongs. Use when the user asks about reasonable-basis, customer-specific, or quantitative suitability, product-specific concerns for complex products, leveraged ETFs, variable annuities, or alternatives, household-level suitability and concentration analysis, hold recommendations, or the institutional suitability exemption. Also trigger when users mention 'is this investment suitable', 'suitability questionnaire design', 'complex product due diligence', 'concentrated position in a client account', 'customer refused to provide their risk tolerance', or ask whether a recommendation fits a customer's profile. (For churning, turnover-ratio, and excessive-trading enforcement triggers, use sales-practices.)
Guide customer onboarding identification, due diligence, and profile maintenance under FINRA Rule 2090, the CIP rules, and the FinCEN CDD Rule. Use when the user asks about onboarding identity verification, beneficial ownership collection for entity accounts, enhanced due diligence for PEPs or high-risk customers at account opening, assigning the initial customer risk rating, KYC refresh triggers, or documentary vs non-documentary verification. Also trigger when users mention 'account opening requirements', 'who is the beneficial owner', 'new client identity check', 'how often to update KYC', 'essential facts for the account', 'foreign customer onboarding', or ask what information must be gathered before opening an account. (For ongoing transaction monitoring, SAR filing, and surveillance-driven risk re-rating, use anti-money-laundering.)
Research roadmap for a legal issue — statutes to check, case law areas to investigate, regulatory frameworks, Westlaw search terms. Leads and frameworks, NOT authoritative citations; students verify and develop everything. Use when a student asks where to start researching, wants a research roadmap for an issue, or needs gaps identified in existing research.
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.
