Development
Make Sentry stack traces readable—upload source maps for JavaScript/TypeScript, or debug files for native and mobile (dSYM, ProGuard/R8, NDK symbols, Dart obfuscation maps, .NET PDBs). Use when frames in Sentry show minified names, bundled paths, hex addresses, “unknown”, or method names with no file/line, instead of your original source.
Make platform abstraction decisions for the Amethyst KMP project. Guides when to abstract versus keep platform-specific, where to place source sets (commonMain, jvmAndroid, platform-specific), and expect/actual patterns. Covers primary targets (Android, JVM/Desktop, iOS—all mature), with web/wasm as possible future targets. Integrates with gradle-expert for dependency issues. Triggers on abstraction decisions (“should I share this?”), source set placement questions, expect/actual creation, build.gradle.kts work, incorrect placement detection, and KMP dependency suggestions.
Work with the Upstash Redis JavaScript/TypeScript SDK for serverless Redis operations. Use for caching, session storage, rate limiting, leaderboards, full-text search (querying, filtering, aggregating with @upstash/redis search extension), and all Redis data structures. Supports automatic serialization/deserialization of JavaScript types. Search also available via @upstash/search-redis and @upstash/search-ioredis adapters for TCP clients
Iteratively optimize cuTile kernel performance through systematic profiling, bottleneck analysis, IR comparison, and targeted tuning. Covers tile sizes, occupancy, autotune configs, TMA, latency hints, persistent scheduling, num_ctas, flush_to_zero, and IR-level debugging. Use when asked to "optimize cutile kernel", "improve kernel perf", "tune cutile performance", "make kernel faster", or iteratively benchmark and refine a cuTile GPU kernel in the TileGym project.
Stream overview, CLI, and router for Chat, Video, Feeds, Moderation, and Agents. Use for any Stream task: building or integrating Stream into web, iOS, Android, React Native, Flutter, Unity, or Unreal apps, building voice or text AI agents with Stream Agents, querying Stream data, running getstream CLI commands, looking up Stream SDK docs, or migrating (from Sendbird, or Feeds v2 to v3). Routes to the right skill
Train or fine-tune sentence-transformers models across `SentenceTransformer` (bi-encoder, dense or static embedding model for retrieval, similarity, clustering, classification, paraphrase mining, dedup, multimodal), `CrossEncoder` (reranker, pair scoring for two-stage retrieval / pair classification), `SparseEncoder` (SPLADE, sparse embedding model for learned-sparse retrieval), and `MultiVectorEncoder` (ColBERT / late-interaction, per-token embeddings scored with MaxSim). Covers loss selection, hard-negative mining, evaluators, distillation, LoRA, Matryoshka, and Hugging Face Hub publishing. Use for any sentence-transformers training task
Help users manage technical debt strategically. Use when someone is dealing with legacy code, planning refactoring work, deciding between rewrites vs. incremental fixes, trying to get buy-in for tech debt reduction, or balancing new features with maintenance.
Search and contribute to the shared AI-modding knowledge base, where field notes record how specific games were modded, decompiled or reverse-engineered (exact versions, route, engine facts, verification, gotchas). Use before starting work on a game ("has anyone modded X?"), when stuck on an engine quirk, and at the end of any modding or reverse-engineering session to write up what was learned and, with the human's OK, open a pull request so the next agent benefits
Drives a running Unity Editor or dev Player through the unity-pipeline package — recompile, run tests, run C# scripts, method-reload code at runtime and audit the project. Use when an agent must control a live Unity instance or automate its tests.
Hands-on project tutor for the AI Engineering from Scratch Projects section. Guides a learner through one stage of a real project per session: read the stage lesson, predict, write the code, run the stage grader, reflect, and record progress in PROJECTS-LEARNING.md. Gives hints, never full solutions. Trigger phrases: "build a project", "next project stage", "continue my project", "start the research report agent".
Evaluates code against Apple's App Store Review Guidelines. Use this skill when reviewing iOS, macOS, tvOS, watchOS, or visionOS app code (Swift, Objective-C, React Native, or Expo) to identify potential App Store rejection issues before submission. Triggers on tasks involving app review preparation, compliance checking, or App Store submission readiness
Use this skill whenever the user wants to work with the Loops CLI from the terminal. This includes installing or updating the CLI, authenticating, storing and selecting API keys, validating credentials, and running commands for contacts, contact properties, lists, events, transactional email, campaigns, email messages, themes, components, and uploads. Trigger on phrases like "Loops CLI", "loops auth login", "loops campaigns create", "loops uploads create", "loops email-messages update", "loops themes list", "loops components get", "loops contacts create", "loops events send", "loops transactional send", "loops api-key", "loops agent-context", "brew install loops-so/tap/loops", or any time the user wants to use Loops from the shell instead of application code.
Scaffold Hono API routes for Cloudflare Workers. Produces route files, middleware, typed bindings, Zod validation, error handling, and API_ENDPOINTS.md documentation. Use after a project is set up with cloudflare-worker-builder or vite-flare-starter, when you need to add API routes, create endpoints, or generate API documentation.
Audit and update an existing GitHub Issue tree. Use for requests such as “audit the tree” or “update the issue tree.” Receive the root tracking issue number, recursively retrieve the entire tree with the sub_issues API, then reassign open issues left under closed parents, reposition orphans, create new Phase parents, and sync phase labels. Preserve the existing root issue body, updating only the Phase tables and audit-history management blocks. For creating a new tree, see create-issue-tree; for implementing issues, see implement-issue-tree.
Use this skill when the user asks to "write a fragment shader", "make a GLSL gradient/noise/plasma background", "create an image transition (dissolve, displacement, glitch)", "add distortion or chromatic aberration", "build an SDF shape shader", "wire up a Three.js ShaderMaterial with uniforms", or "do GPU post-processing". Covers GLSL fragment shaders, noise/fbm, SDFs, domain warping, transitions, and Three.js integration
Package and release a finished game mod. Covers the pre-release lint (no game files, decompiled code or leaked keys), README and install steps, credits and AI disclosure, versioning, where to upload (Nexus Mods, Steam Workshop, Thunderstore, mod.io, GitHub releases) and the post with a video. Use when the user wants to ship, share, upload, release or post a mod
The entry point for building any Salesforce native mobile app on iOS or Android. TRIGGER when the user says: "build a Salesforce iOS app", "add Salesforce login to my Android app", "set up Mobile SDK", "add MobileSync / SmartStore offline storage", "embed an Agentforce agent in my mobile app", "add Agentforce chat to iOS/Android", or otherwise asks to create, extend, or integrate a Salesforce mobile experience in Swift or Kotlin (MSDK, Agentforce SDK, or both). SKIP when the user is building a non-Salesforce mobile app, using React Native / Flutter / Ionic without Salesforce integration, asking about generic mobile UI design, or working on a Salesforce-adjacent web/desktop surface (LWC, Experience Cloud, Mobile Publisher branding-only).
Build, modify, or review Stripe Apps and extensions using the relevant documentation and reference guides. Use for custom Stripe Dashboard UI, stripe-app.yaml, @stripe/ui-extension-sdk, @stripe/extensibility-sdk, script extensions, extension interfaces, custom workflow actions, and apps that authenticate to Stripe or react to events. Also use when deciding whether a Stripe extension can support the user's billing or workflow requirements.
Set up VideoDB and write code against the VideoDB Python SDK. Use for "setup videodb" or "/videodb setup", when the user wants Python code, a script or a notebook rather than a chat answer, for bulk uploading or indexing a folder or library of media, for sandbox compute with open-weight models, and for any video task that video-search, video-clips, video-subtitles, video-edit and video-live do not cover. Screen recording belongs to video-live, AI-generated music, voiceover, images or video to video-edit, and dubbing to video-subtitles.
Use this when the user mentions component models, component definitions, component filters, block configuration for the Universal Editor, UE block setup, adding a new block to UE, configuring block properties or block authoring fields, or wants to create an EDS/Franklin block with Universal Editor support, modify block fields, or add a block to the section filter. Covers creating and editing the three JSON files that control how AEM Edge Delivery Services blocks appear and behave in the Universal Editor — component-definition.json, component-models.json, and component-filters.json.
Generates minimal security fixes using transactional isolation (shadow directories or file backups), applies patches, and verifies them. Use when security findings are successfully reproduced and need patches applied and verified. Don't use for initial vulnerability research or reproduction payload generation.
Use this when a user wants to create a brand-new AEM Edge Delivery site from scratch and no GitHub repository or DA content exists yet — triggers include 'set up a new site', 'create a new EDS project', or 'onboard a new site'. Covers creating the GitHub repo from the boilerplate, installing aem-code-sync, seeding initial DA content (nav, footer, homepage), and returning a live preview URL. For importing or migrating existing pages use page-import; for building blocks on an existing site use content-driven-development.
A comprehensive starting point for AI agents to work with the Ionic Framework. Covers core concepts, components, CLI, theming, layout, lifecycle, navigation, and framework-specific patterns for Angular, React, and Vue. Pair with the other Ionic skills in this collection for deeper topic-specific guidance like app creation, framework integration, and upgrades.
Interactively guides the design and implementation of custom deterministic orchestrator harnesses. Use when a user wants to build their own pipeline to wrap and run Mantis skills reliably. Don't use for executing the default pipeline directly.
Use when adding, modifying, optimizing, or debugging CuTile autotuning code. Trigger signals: `exhaustive_search` / `replace_hints` / `hints_fn` / `cuda.tile.tune` in code, `autotune` in filenames, or correctness/performance issues in autotuned CuTile kernels. Covers: tune-once/cache/launch pattern, per-architecture configs (sm80–sm120), parameter space design (tile sizes, occupancy, num_ctas), and 7 common pitfalls with solutions.
React Three Fiber (R3F) and Poimandres ecosystem best practices. Use when writing, reviewing, or optimizing R3F code. Triggers on tasks involving @react-three/fiber, @react-three/drei, zustand, @react-three/postprocessing, @react-three/rapier, or leva.
Use this skill when creating, modifying, or debugging Docker Compose configurations, even if the user just says they need to wire services together, add a database to their stack, or set up a local development environment with multiple containers. Covers service definitions, health checks, dependency ordering, volumes, networks, environment variables, and development overrides.
