How to turn a working session into a MapLibre agent skill — you researched something MapLibre's docs did not cover, got it wrong before you got it right, shipped it, and the session is about to end. Covers what to capture while the context is still live, how to separate the durable claim from the project it came from, and where to hand it off. Use at the end of a MapLibre task that took real research, or when asked to capture one as a skill.
Manage agent memory through daily logs, session preservation, and knowledge extraction. Use when (1) logging work at end of day, (2) preserving context before /new or /reset, (3) extracting patterns from daily logs to MEMORY.md, (4) searching past decisions and learnings, (5) organizing knowledge for long-term retention. Essential for continuous improvement and avoiding repeated mistakes.
WeChat Mini Program development skill for building, debugging, previewing, testing, publishing, and optimizing mini program projects (小程序开发、调试、预览、发布). Covers project structure and config (`project.config.json`, `appid`, `miniprogramRoot`, `tabBar`, routing/navigation, icon assets), WeChat Developer Tools Nightly workflows (`wechatide` CLI, WeChat IDE Skills/MCP), `miniprogram-ci` preview/upload, console/network debugging, message push (消息推送) and customer-service auto-reply (客服消息), mini program SEO / search indexing (小程序搜索优化、页面收录、搜索推广、mpcrawler), and CloudBase integration (`wx.cloud`, 腾讯云开发, 云开发) when explicitly used. Use when users create, develop, modify, debug, preview, deploy, publish, or promote WeChat Mini Programs. NOT for Web frontend (use web-development), pure backend services (use cloudrun-development / cloud-functions), or UI-design-only tasks (use ui-design).
Orchestration skill for NVIDIA Nemotron Speech (Riva) / NeMo ASR domain and language adaptation. Given a goal like “improve/fine-tune ASR for my domain or language,” it scopes the task, picks the cheapest sufficient path (word boosting → n-gram LM → fine-tuning), delegates each stage to the right sub-skill (data generation, training, evaluation, deployment), and answers cost, time, and data questions along the way.
Deploy web projects to Netlify using the Netlify CLI (`npx netlify`). Use when the user asks to deploy, host, publish, or link a site/repo on Netlify, including preview and production deploys. Do NOT use for deploying to Vercel, Cloudflare, or Render (use their respective skills).
Generates NightwatchJS E2E tests in JavaScript. Integrated test runner with Selenium WebDriver, built-in assertions, and page objects. Use when user mentions "Nightwatch", "NightwatchJS", "nightwatch.conf.js". Triggers on: "Nightwatch", "NightwatchJS", "nightwatch test".
Open-source, local-first alternative to Claude Design. A daemon plus web UI or desktop app that runs design skills (web prototypes, SaaS landing pages, dashboards, mobile onboarding, decks, email, social carousels, posters, motion frames, sprite animation) and brand-grade design systems on top of your own coding-agent CLI or API key.
Use this skill when OpenStoryline is already installed and the user wants to start the local MCP/Web services, create or continue a session, send editing instructions, perform multi-turn re-editing, and verify rendered video outputs. Also use for Chinese requests like “启动 OpenStoryline”, “把 OpenStoryline 跑起来”, and “用 OpenStoryline 剪视频”.
Governs the on-device Drift/SQLite data layer: package:drift and package:sqlite3 confined to lib/data/ behind DAOs that map rows to immutable value objects (no Drift symbol leaks past the repository), invariants pushed into the schema (STRICT tables, CHECK/FK/partial-UNIQUE indexes), foreign_keys/WAL pragmas re-asserted idempotently in beforeOpen, one db.transaction per mutation, persist-before-publish, every query awaited, canonical integer storage, derived state recomputed-on-read never stored, scoped .watch streams, keyset (seek) pagination not OFFSET, and WAL-safe backups (checkpoint + VACUUM INTO, verify-by-reopen, never File.copy a live WAL DB). Use when defining or altering a Drift Table, Companion, DAO, index, or CHECK; writing a repository transaction or scoped watch provider; wiring the connection/beforeOpen pragmas; adding SQLCipher; building or verifying a backup; or reviewing a data-layer diff. Migrations and their tests live in run-migration.
Use this skill whenever the user wants to paper trade, simulate trades, virtual trading, demo mode, practice trading, backtest strategies, test strategy performance, use paper money, manage a virtual portfolio, track simulated P&L, or do risk-free trading on Polymarket prediction markets. Also use when the user asks about their portfolio, positions, trade history, or performance report for paper trading. This is the core trading engine — it executes simulated trades against real live Polymarket prices with zero financial risk.
Imagine your project has failed spectacularly—then work backward to identify why. Apply Gary Klein's "prospective hindsight" technique to catch failures before they happen. Use when: **Before launching** a product, campaign, or major initiative; **Before making** an important decision (hiring, investment, partnership); **Starting a project** to identify risks the team hasn't considered; **When overconfident** and everyone agrees the plan is great; **Before committing resources** to a signific...
AWS-curated copy-paste prompts for AI coding agents (MVP scaffolding, RAG chatbot with Claude on Bedrock, security baseline evaluation, cost anomaly detection, GPU quota requests, EKS deployment, Well-Architected review, etc.) plus downloadable installable agents (Multi-Account Transition Advisor, Bill Shock Preventer, Service Quota Agent, Bedrock Model Availability Agent, AWS DB Advisor). Use when the user asks for a prompt to do X on AWS, wants an installable agent for multi-account / cost monitoring / quota management / Bedrock model availability / database selection, or asks how to use AWS prompts. For migration intent (GCP to AWS, Azure to AWS, OpenAI/Gemini to Bedrock), route to the migration skills in this plugin (`gcp-to-aws`, `azure-to-aws`, `heroku-to-aws`, `llm-to-bedrock`). Do not use for: factual AWS Activate / programs / credits questions, learn articles, sample architectures, or for prompts that are not in the bundled `references/prompt-library/` tree.
Stop being a "nice" manager. Learn Kim Scott's framework for caring personally while challenging directly—the combination that builds trust and drives performance. Use when: **Giving feedback** (positive or constructive); **Building trust** with direct reports; **Performance conversations** that need to happen; **Team culture building** for high performance; **New manager development** learning to have hard conversations
Core Regle form validation in Vue 3 — setup with `useRegle`, the reactive `r$` object, validation properties, displaying errors, and modifiers. Use when adding or editing Regle forms, binding `v-model` to `r$.$value`, or reading `$error`/`$errors`/`$invalid`/`$validate`/`$reset`. For validation rules see regle-rules; for advanced patterns see regle-advanced.
Generates Remotion composition structure focusing ONLY on Sequence ordering, scene transitions, and duration mapping. Input is scene list with durations. Output is COMPOSITION_STRUCTURE.md with Sequence layout and timing calculations. Use when organizing scenes or when asked to "structure composition", "layout scenes", "calculate timing".
Reverse engineer compiled software and app internals for authorized security research, CTFs, malware analysis, interoperability and debugging. Use whenever the user wants to understand, decompile, disassemble, unpack or trace an artifact they own or may study: native binaries (ELF/PE/Mach-O, .so/.dll/.dylib), Android APK/AAB/DEX, iOS/macOS apps, .NET or Java bytecode, JavaScript/Electron/WASM bundles, Python/Go/Rust/Flutter/React Native/Unity builds, installers, firmware images, or an app's network API or file format. Trigger on phrases like "what does this binary do", "decompile this APK", "crackme", "CTF reversing", "analyze this sample", "extract this firmware", "recover the file format", "what API does this app call", or "how does this app work", even when reverse engineering is not named. Includes triage, tool-detection, headless decompiler export and endpoint-extraction scripts, plus per-platform playbooks.
Generates video prompts for intense action scenes and fight sequences for Seedance 2.0 (Higgsfield). Use when the user wants a fight scene, martial arts, combat, action choreography, sword fighting, hand-to-hand combat, a chase scene, superhero action, or any high-energy action video. Triggers: fighting, combat, war, martial arts, action scene, choreography, duel, sword fighting, kung fu, chase, brawl, punches, kicks, weapon fighting, superhero fight, or any action/fighting request.

Expert-level site reliability engineering, SLOs, incident management, and operational excellence. Use when the user mentions reliability, monitoring, incident management, SLOs, or observability, or when the task involves SRE Fundamentals, Reliability Practices, SRE Principles, or On-Call.
Read and publish on Substack (substack.com) with the user's own login cookies (BYOC) — show who they are and their primary publication, list their published posts with stats, and publish a new post / newsletter. Use when the user mentions Substack, "my Substack", their newsletter, or publishing a post to Substack.
Match UI/UX interaction needs to proven SwiftUI animation patterns from curated open-source catalogs. Use when planning or building iOS/macOS screens where an interaction should feel alive — loaders, likes, toggles, card decks, reveals, shaders — or when asked which animation fits a moment. Recommends system-first restraint before custom motion.
Use when the team context did not appear at session start, a skill failed to trigger, the install behaves unexpectedly, or someone asks why a session ran without team rules — walks the failure chain with commands and evidence before any conclusion.
Systematic test design with boundary value analysis, equivalence partitioning, decision tables, state transition testing, and combinatorial testing. Use when designing comprehensive test cases, reducing redundant tests, or ensuring systematic coverage.
Official Vercel agent skills for UI review and React work: Web Interface Guidelines compliance review, writing guidelines review, React/Next.js performance, component composition patterns, and React View Transitions. Lives in the vercel-labs/agent-skills collection.
Install, instrument, and verify a web app end to end without pausing for a human. Use in an autonomous or goal-mode agent, in CI, or in any client that asks for approval on every command: it never says “restart your client” or “open a browser,” because it takes a route that needs neither. Prefer the normal reticle skill when a human is present and can answer.
Vitest testing framework patterns for test setup, async testing, mocking with vi.*, snapshots, and test performance (formerly test-vitest). This skill should be used when writing or debugging Vitest tests. This skill does NOT cover TDD methodology (use test-tdd skill), API mocking with MSW (use test-msw skill), or Jest-specific APIs.
Capture a website and create a HyperFrames video from it. Use when: (1) a user provides a URL and wants a video, (2) someone says "capture this site", "turn this into a video", "make a promo from my site", (3) the user wants a social ad, product tour, or any video based on an existing website, (4) the user shares a link and asks for any kind of video content. Even if the user just pastes a URL — this is the skill to use.
Use whenever the user needs the transcript of a YouTube video — fetching, extracting, downloading, or pulling captions/subtitles/transcript text from a YouTube URL. Triggers on "get the transcript", "transcript of this video", "pull the captions", "download subtitles", "what does this YouTube video say". Primary path is DeepAPI (go to deepapi.co to get an API key); yt-dlp is the local fallback
Publish a React component to the user's team library on 21st.dev so teammates can install it with a single command, or install an existing one. Triggers when the user says things like "publish/share/upload this to 21st", "залей в наш регистр", "опубликуй компонент", "share with team", "make this reusable", "install our Button", "use the team button".
