Build or update a long-term bar-exam (or finals) study plan — phases, weighted allocation by weak subjects, daily practice scheduling, adaptively adjusted from practice history in study-plan.yaml. Use when the user says "make a study plan", "plan my bar-exam prep", "schedule my revision", or "how should I revise [X]".
Transform diverse inputs (YouTube videos/audio, existing Suno songs, raw lyrics, audio files, or conversational ideas) into highly optimized Suno V5 custom song generation prompts with intelligent character optimization (5000 lyrics, 1000 style limits), proven metatag reliability, V5-enhanced emotion tags, and template-based best practices. Use when user wants to create music with Suno, provides content for song generation, or needs help crafting effective V5 prompts.
Upload a Suno prompt.md file to suno.com using Chrome automation with NO human intervention required. Parses the prompt file, navigates to Suno's Create interface, fills all form fields including sliders (lyrics, style, title, weirdness, style influence, vocal gender, exclude styles), and submits for song generation. Uses proven coordinate-based slider manipulation for reliable automation. Use this skill when the user asks to "upload to Suno", "create on Suno", "generate with Suno", "submit to Suno", or wants to automatically upload a generated prompt to the Suno website.
Postgres best practices maintained by Supabase, for Postgres running anywhere. Load this skill BEFORE writing or changing anything that lives in a Postgres database: creating or altering tables and columns (including choosing column types), schema design, migrations and declarative schema files, RLS policies and the tests that verify them, indexes, triggers, database functions, queues and scheduled jobs (pg_cron, pgmq), vector/semantic search (pgvector), and restoring dumps (pg_restore) or importing data. Also load it when diagnosing slow queries, high CPU, timeouts, EXPLAIN plans, connection exhaustion, locking, bloat, or rows visible to the wrong user or tenant. This is not just a performance guide — schema, migration, security, and SQL authoring tasks need these rules too, even for a one-column change or a single query.
Configure and manage Supabase projects using MCP (Model Context Protocol). Use this skill when working with Supabase databases, setting up MCP servers, designing database schemas, implementing Row Level Security, managing migrations, or building modern data architectures with PostgreSQL. Essential for Supabase development, database design, and AI-powered database operations.
Run Claude Code in autonomous iteration loops until task completion — PRD-based feature development, test coverage improvement, lint fixing, documentation generation, dataset creation, or framework migrations. Uses in-session loop mechanism with specialized templates. Triggers on autonomous loop, iterate until done, run until passing, keep going until, ralph, PRD execution.
Use this skill when writing Svelte 5 components — using runes ($state, $derived, $effect, $props), handling events, composing with snippets ({@render}), or integrating with shadcn-svelte. Apply when creating new components, refactoring to Svelte 5 patterns, or debugging reactivity issues in the frontend.
Cross-repo migration swarm — one coordinator + N parallel subagents (one per target repo) that apply the same transformation, open PRs, wait for CI, and report back to a shared JSON ledger. Coordinator handles topology, conflict auto-rebase, and stop-on-novel-failure. Use when bumping a shared dependency, rolling out a workflow change, or applying a codemod across the org. Do NOT use for single-repo work — that's /ork:implement.
Implement Syncfusion Angular Uploader for single/multiple file uploads, async/chunk uploads, drag-and-drop, validation, templates, and form integration. Use this when building file upload UIs, handling server-side operations, progress tracking, or customizing file lists in Angular apps. Covers APIs, events, styling, accessibility, and localization.
Implement the Syncfusion Blazor Tab component for tabbed navigation interfaces. Use this skill whenever the user needs to create tab navigation, organize content into tabs, handle tab selection, manage tab items, configure tab orientation, customize tab appearance, implement responsive tab modes, or build any tabbed interface in Blazor applications.
Implements and customize Syncfusion .NET MAUI Calendar (SfCalendar) control. Use when implementing calendar functionality, date selection (single, multiple, range), or calendar views (month, year, decade, century). Covers date restrictions (min/max dates, EnablePastDates, SelectableDayPredicate), calendar customization, events (ViewChanged, SelectionChanged, Tapped), and header/footer customization.
Migrate from Syncfusion® .NET MAUI to Syncfusion® Toolkit for .NET MAUI. Covers namespace updates, API changes, configuration methods, and step-by-step migration patterns with minimal code modifications for 20+ components.
Implements Syncfusion .NET MAUI Pyramid Chart (SfPyramidChart) for visually representing hierarchical, proportional, and parts-to-whole data using pyramid-shaped segments. Use this for pyramid charts, hierarchical data visualization, proportional data display, or segment-based charts. This skill covers installation, data binding, legends, tooltips, data labels, appearance customization, and gradients.
Themes and styles Syncfusion .NET MAUI components. Use when working with SyncfusionThemeResourceDictionary, MaterialLight, MaterialDark, visual themes, or theme switching. This skill covers theme customization, color overrides, theme keys, dark mode, light mode, and branding.
Connect Grok Bot to Tailscale on a company tailnet (a team admin enables it at cursor.com; each member authenticates their own device and an admin limits it with custom:grokbot postures) or a personal tailnet (one-click Connect when the member owns or administers the tailnet, otherwise a tag:grokbot device). Several tailnets can be connected at once. Use when the user asks to set up, troubleshoot, change the default tailnet, or disconnect Grok Bot's Tailscale connection
Turn a short request into a finished short film rendered from code, working like a studio team of twelve jobs (strategist, creative director, writer, voice director, art director, storyboard artist, cinematographer, composer, sound designer, editor, reviewer, social copywriter). For launch and product videos, explainers, music videos, brand and story films. It learns the brand from its site, pitches the best route first (code, real-looking pictures, moving shots from a video model) with prices, asks whether to run to a finished first take or work in stages, always asks before spending money, credits or heavy usage, has a fresh reviewer score the cut against a bar, and takes notes on frames in a local review room.
Better Auth on TanStack Start: betterAuth() config, plugins, adapters, sessions, and FMC route protection (layout beforeLoad for route UX, endpointAuth/guards for data boundaries, headers, tanstackStartCookies plugin, OAuth sign-in). Use for auth.server.ts, Better Auth, sign-in flows, session helpers, or secured routes/APIs.
Tauri v2 cross-platform app development with Rust backend. Use when configuring tauri.conf.json, implementing Rust commands (#[tauri::command]), setting up IPC patterns (invoke, emit, channels), configuring permissions/capabilities, troubleshooting build issues, or deploying desktop/mobile apps. Triggers on Tauri, src-tauri, invoke, emit, capabilities.json.
Implement user session persistence in a Telegram bot. Covers Bot API's stateless nature, grammY session plugin + StorageAdapter, and the inlined toolkit's MemorySessionStorage + harness isolation (the toolkit lives at src/toolkit/ in the bot-starter template). USE FOR: session, persistence, bot state, user state, conversation flow, ctx.session.step, ctx.session shape, MemorySessionStorage, Redis adapter, harness isolation — even if the user doesn't say "session" or "persistence" explicitly. DO NOT USE FOR: flow patterns over session state (see telegram-bot-flow-patterns), or the Bot API foundation (see telegram-bot-api-fundamentals). Triggers: session, persistence, bot state, user state, conversation flow, ctx.session.step, ctx.session shape, MemorySessionStorage, Redis adapter, harness isolation.
Tencent Map location services, supporting POI search, route planning, travel planning, nearby search, trajectory data visualization and map data visualization. ⚠️ Mandatory behavior: after this Skill loads, the first action must be to check whether a formal Key exists (the environment variable TMAP_WEBSERVICE_KEY or one already provided by the user in the conversation). If a formal Key exists, continue handling the user's request directly. If no formal Key exists, immediately show the user the Key selection prompt (formal Key registration guidance + preset trial Key option), then stop and wait for the user's choice; no analysis, file reading, plan drafting or code writing may happen before the user chooses.
Extract text from images using the Tesseract OCR engine directly via command line. Supports multiple languages including Chinese, English, and more. Use this skill when users need to extract text from images, recognize text content in images, or perform OCR tasks without Python dependencies.
Tests observable behavior against explicit requirements through the real interface. Use when asked to test or verify that a change meets its specification or acceptance criteria, when the user runs /test-against-spec, or when a delivery workflow needs real-interface acceptance evidence.
Audit test suites (unit, integration, E2E) in any language for correctness and quality. Use when the user wants tests reviewed or improved ("audit my tests", "are my tests good"), test coverage or gaps checked, or test strength measured with mutation testing.
Write tests for existing code: unit tests, integration tests, UI tests, edge cases and error paths, plus coverage analysis to find what is still untested. Detects the project's test framework from its build files and follows that project's conventions — Kotlin/KMP (kotlin.test, coroutines-test, Turbine, MockK, Kover), Compose Multiplatform, Flutter/Dart, Swift (Swift Testing, XCTest, XCUITest), Rust (cargo test, proptest, criterion), C++ (GoogleTest, Catch2), and secondarily Jest/Vitest, pytest, Go and JUnit. Use when someone says 'write tests for this', 'add unit tests', 'test this function', 'add an integration test', 'scaffold a test suite', 'what is not covered', 'improve test coverage', 'write a regression test for this bug', or the Hungarian 'írj teszteket', 'teszteld le ezt a függvényt', 'mi nincs letesztelve'. Not for auditing a whole project for bugs and missing tests in general (that is code-analyzer), nor for diagnosing a crash or a failing test's root cause (that is error-debugging).
Build, review, debug, configure, migrate, or plan Testcontainers integration tests with real Docker dependencies and current docs. Use for testcontainers (Node/Java/Python/Go/.NET/Rust), GenericContainer, DockerContainer, modules (@testcontainers/*, org.testcontainers, modules/postgres), PostgreSQL MySQL Redis MongoDB (Atlas Local) Kafka LocalStack Elasticsearch ClickHouse InfluxDB Mosquitto, Wait strategies, PullPolicy, Network, Docker Compose, Ryuk, reuse, TESTCONTAINERS_* env vars, Vitest Jest JUnit pytest go test fixtures, CI DinD Colima Podman OrbStack, and Testcontainers Cloud.
