animate
by hushh-labs
Build an animation from scratch, making the decisions in the order that determines whether it feels right — should it animate at all, what purpose, which tool, which properties, which curve and duration, how it interrupts, how it exits. Writes the implementation. Use when asked to animate something, add motion, make a component feel alive, or build a transition. For critiquing existing motion use review-animations; for auditing a whole codebase use improve-animations.
frontend-native-surface-mapper
by hushh-labs
Use when regenerating or auditing the frontend surface map that joins app routes, page files, Next.js API proxies, backend endpoint families, native transport, Capacitor plugins, and voice/action contracts.
remix
by remix-run
Build and review Remix 3 applications using the remix npm package and subpath imports. Use when working on Remix app structure, routes, controllers, middleware, validation, data access, auth, sessions, file uploads, server setup, UI components, hydration, HMR, navigation, or tests.
angular-new-app
by angular
Creates a new Angular app using the Angular CLI. This skill should be used whenever a user wants to create a new Angular application and contains important guidelines for how to effectively create a modern Angular application.
make-demo
by remix-run
Create or revise demos in the Remix repository. Use when adding a new demo under demos/, updating an existing demo, or reviewing demo code to ensure it showcases Remix packages, strong code hygiene, and production-quality patterns.
build-prevail
by microsoft
Build and test the PREVAIL verifier (external/ebpf-verifier) standalone. Use this skill when asked to build, test, or iterate on the PREVAIL verifier, run YAML verification tests, or work with the verifier's cmake build system.
add-package
by remix-run
Create or align a package in the Remix monorepo to match existing package conventions. Use when adding a brand new package under packages/, or when fixing an existing package's structure, test setup, TypeScript/build config, code style, and README layout to match the rest of Remix 3.
nx-plugins
by nrwl
Find and add Nx plugins. USE WHEN user wants to discover available plugins, install a new plugin, or add support for a specific framework or technology to the workspace.
run-nx-generator
by nrwl
Run Nx generators with prioritization for workspace-plugin generators. Use this when generating code, scaffolding new features, or automating repetitive tasks in the monorepo.
account-state
by vitorpamplona
Account state and in-memory event store patterns in Amethyst. Use when working with Account.kt (per-user state objects — kind3FollowList, nip65RelayList, muteList, bookmarkState, each exposing a .flow StateFlow), LocalCache (the object-level event store backed by LargeCache), User/Note model classes, or any ViewModel that reads user-specific state. Covers how account events cascade from relay arrival to UI state, how to add a new account-scoped setting, and when to read from LocalCache vs subscribe to a StateFlow.
amy-expert
by vitorpamplona
Patterns for extending amy, the Amethyst CLI in cli/. Use when adding an amy <verb> command, touching files under cli/src/main/kotlin/…/cli/, wiring a new subcommand into Main.kt, writing an interop test script that drives Amy, or extracting logic out of amethyst/ into commons/ so a CLI command can call it. Enforces the thin-assembly-layer rule (no Nostr protocol or business logic inside cli/), the dual-output contract (text by default, single-line JSON object on stdout under --json, exit codes 0/1/2/124), and the extract-from-Android recipe. Complements nostr-expert (protocol in Quartz), kotlin-multiplatform (expect/actual for extraction), and feed-patterns / account-state / relay-client (where the business logic should end up). NOT for general Nostr or Kotlin work — those have their own skills.
auth-signers
by vitorpamplona
Signer abstraction patterns in Amethyst. Use when working with event signing, choosing between a local keypair (NostrSignerInternal), a remote NIP-46 bunker signer (NostrSignerRemote), or a NIP-55 Android external-app signer (NostrSignerExternal). Covers the abstract NostrSigner base class, SignerResult contract, how to wire a new flow that needs to sign events, and the security/UX trade-offs between signer kinds.
kotlin-expert
by vitorpamplona
Advanced Kotlin patterns for AmethystMultiplatform. Flow state management (StateFlow/SharedFlow), sealed hierarchies (classes vs interfaces), immutability (@Immutable, data classes), DSL builders (type-safe fluent APIs), inline functions (reified generics, performance). Use when working with: (1) State management patterns (StateFlow/SharedFlow/MutableStateFlow), (2) Sealed classes or sealed interfaces, (3) @Immutable annotations for Compose, (4) DSL builders with lambda receivers, (5) inline/reified functions, (6) Kotlin performance optimization. Complements kotlin-coroutines agent (async patterns) - this skill focuses on Amethyst-specific Kotlin idioms.
nip85-trusted-assertions
by vitorpamplona
The NIP-85 trusted-assertions model in Quartz (nip85TrustedAssertions/) — kind 10040 trust-provider lists, kind 30382 contact cards / user assertions, 30383 event assertions, 30384 addressable assertions, 30385 external-id assertions. Use when building or parsing these events, working with the typed tags (RankTag, HopsTag, FollowerCountTag, ServiceProviderTag/ServiceType, …), wiring a consumer that resolves a 10040 provider entry to the 30382s it signs, ranking on assertion values, or touching the GrapeRank publisher, contact-card nicknames, or the trust projection of an external store.
quartz-integration
by vitorpamplona
Integration guide for using the Quartz Nostr KMP library in external projects. Use when: (1) adding Quartz as a Gradle dependency, (2) setting up NostrClient with WebSocket, (3) creating/signing/sending events, (4) building relay subscriptions with Filter, (5) handling keys with KeyPair/NostrSignerInternal, (6) using Bech32 encoding/decoding (NIP-19), (7) platform-specific setup (Android vs JVM/Desktop), (8) NIP-57 zaps, NIP-17 DMs, NIP-44 encryption in external projects, (9) running a relay on Quartz and serving/building its NIP-11 relay information document (application/nostr+json).
nx-generate
by nrwl
Generate code using nx generators. USE WHEN scaffolding code or transforming existing code - for example creating libraries or applications, or anything else that is boilerplate code or automates repetitive tasks. ALWAYS use this first when generating code with Nx instead of calling MCP tools or running nx generate immediately.
bit-cli
by teambit
'MUST consult before running ANY bit command. Do NOT guess bit commands from memory. This skill tells you the right command, correct syntax, subcommands, and flags.'
svelte-code-writer
by sveltejs
CLI tools for Svelte 5 documentation lookup and code analysis. MUST be used whenever creating, editing or analyzing any Svelte component (.svelte) or Svelte module (.svelte.ts/.svelte.js). If possible, this skill should be executed within the svelte-file-editor agent for optimal results.
creating-skills
by dotnet
Create custom agent capabilities when discovering novel tools, receiving task-agnostic tips from reviewers, or after researching specialized workflows not covered in existing instructions. Teaches structure, YAML optimization for LLM discoverability, and token efficiency.
web-design-guidelines
by vercel
Review UI code for Web Interface Guidelines compliance. Use when asked to "review my UI", "check accessibility", "audit design", "review UX", or "check my site against best practices".
changewaves
by dotnet
'Manage MSBuild Change Waves: create new waves, condition features behind opt-out flags, write tests for wave-gated features, document change waves in ChangeWaves.md, and retire expired waves. Use when adding changes that need an opt-out or rotating out old change waves. Changes that introduce a user-visible behavior change should consider whether to use a changewave.'
py
by crazyguitar
Comprehensive Python programming reference covering syntax, concurrency, networking, databases, ML/LLM development, and HPC. Use for: Python questions, Python interview preparation, debugging, performance optimization, async patterns, library examples, code review, best practices, MLOps workflows, distributed computing, security implementations, and any Python development tasks.
write-ui-tests
by dotnet
Creates UI tests for a GitHub issue and verifies they reproduce the bug. Iterates until tests actually fail (proving they catch the issue). Use when PR lacks tests or tests need to be created for an issue.
