Development
Use this skill for reinforcement learning tasks, including high-performance RL training, custom environment development, vectorized parallel simulation, multi-agent systems, or integration with existing RL environments (Gymnasium, PettingZoo, Atari, Procgen, etc.). Use it to implement PPO training, create PufferEnv environments, optimize RL performance, or develop policies with CNNs/LSTMs.
Emulated Resend email API for local development and testing. Use when the user needs to send emails locally, test transactional email flows, implement magic link or verification code auth, inspect sent emails, manage domains/contacts/API keys, or work with the Resend API without sending real emails. Triggers include “Resend API”, “emulate Resend”, “send email locally”, “test email”, “magic link”, “verification email”, “email inbox”, “RESEND_BASE_URL”, or any task requiring a local email API.
ShipSwift skill library — 116 production-ready SwiftUI skills for iOS/macOS covering animations (view transitions, particle transitions, change effects, shimmer, confetti, typewriter, 27 Metal shaders), charts (line, bar, donut, radar, heatmap, 3D network graph), UI components (onboarding, alert, stepper, search bar, cached remote images) and full-stack modules (Cognito/Supabase auth, camera, chat, StoreKit subscriptions, CDK infra). Use when building SwiftUI features, adding animations/charts/components, or when the user mentions ShipSwift
Wires the Aura Topbar (@aura/topbar) into Dune/Fusion apps as the single top navigation bar — breadcrumbs, optional center Tabs or Segmented control, right utility strip (Share, notifications, theme menu, Atlas, user Avatar), and light/dark theme switching. Use when adding a topbar, app header, navigation bar, breadcrumbs, or theme switcher to a Dune or Fusion app, or when scaffolding a new Dune/Fusion application.
Scope a feature end to end and write an implementation spec under specs/ from an accepted proposal — current-system mapping, goals/non-goals, a Decision Log for one-way-door choices, a live Open Questions backlog, and a real migration + test plan. Read when asked to write a spec, scope this feature, turn this proposal into a spec, plan the implementation, or break this into tasks. Do NOT fire on frame a proposal or write the PRD (sibling frame-a-proposal — a PRD frames a change before it is accepted; this skill starts once one is), record a decision or write the ADR (record-a-decision), write a postmortem (write-a-postmortem), or review this design (review-a-design) — those are separate skills. Complements the platform open-knowledge skill; does not replace it.
Architecture validation and patterns for clean architecture, backend structure enforcement, project structure validation, test standards, and context-aware sizing. Use when designing system boundaries, enforcing layered architecture, validating project structure, defining test standards, or choosing the right architecture tier for project scope
Use when building a storefront app or UI on the Bagisto Shop API — a customer-facing storefront, catalog, cart, checkout, customer account, wishlist, compare, reviews, or any page or component of a shop on the API, whether web, mobile or custom. Ask the client's platform and stack first, and treat the api-docs as the source of truth for exact shapes. Trigger phrases include "products", "cart", "checkout", "coupons", "customer login", "customer account", "wishlist", "storefront on the API".
Performs initial binary triage by surveying memory layout, strings, imports/exports, and functions to quickly understand what a binary does and identify suspicious behavior. Use when first examining a binary, when the user asks to triage, survey, or analyze a program, or wants an overview before deeper reverse engineering.
Improve, debug, and extend an existing Contentful App Framework custom app in a customer's own repository. Use when users provide a bug report, feature request, support note, customer feedback, or direct change request for an existing custom app, including app configuration, sidebar, field editor, dialog, page, home, App Action, Function, installation parameters, local validation, or PR preparation. Also triggers on “fix my Contentful app”, “improve a custom app”, “enhance App Framework app”, “debug custom app”, “update sidebar app”, and “custom app feature request”. Not for creating a brand new app from scratch (contentful-custom-app-from-scratch), generic API examples (contentful-api), migrations (contentful-migration), or website integration (contentful-nextjs)
Groups existing components into logical business domains to plan service-based architecture. Use when asking "which components belong together?", "group these into services", "organize by domain", "component-to-domain mapping", or planning service extraction from an existing codebase. Do NOT use for identifying new domains from scratch (use domain-analysis) or analyzing coupling (use coupling-analysis).
Design and implement context-fit frontend interfaces with deliberate art direction, accessible interaction, responsive behavior, complete states, and rendered verification. Use when creating or substantially reworking pages, components, product workspaces, dashboards, marketing sites, editorial surfaces, commerce flows, or justified immersive experiences.
Use when building or auditing web pages for speed: Core Web Vitals (LCP, INP, CLS), blocking resources, bundle size, fonts, and caching. Not for visual design (sheleg-design) or conversion work. Opt out: no wiring, без обвязки. Triggers: “PageSpeed,” “Lighthouse,” “ускорить сайт,” “медленно грузится.”
Mandatory initialization workflow for new Keboola Python components — use this skill before writing any code. Contains the exact cookiecutter command, Keboola-specific post-template cleanup steps, KBC_DATADIR directory structure, data/config.json format, and first commit format that are easy to get wrong without this reference. Invoke whenever the user is starting from a fresh or empty repository, has never built a Keboola component before, wants to run the cookiecutter template, or says things like "new extractor for X", "build ex-something from scratch", "fresh repo", "empty git repo", "brand new component", "never done this in keboola", "initialize a component", "scaffolding a new component", "just initialized the git repo", "nothing set up yet". Not for existing components that already have src/component.py.
Clean up local branches whose remote tracking branch is gone. Use when the user says "clean up branches", "delete gone branches", "prune local branches", "clean gone", or wants to remove stale local branches that no longer exist on the remote. Also handles removing associated worktrees for branches that have them.
Create rich HTML documents for project specs, implementation plans, design exploration, RFCs, and proposals. Use whenever the user asks for a spec, plan, RFC, design doc, or proposal, or wants to explore approaches, options, or alternatives—even when they don’t explicitly say “HTML.” Strongly prefer HTML over markdown for any planning artifact longer than a screen, especially when it will be shared with reviewers or fed back to the agent for implementation.
Implements Google Material Design 3 (Material You) — adaptive color, tonal surfaces, dynamic theming, spring-based motion, and the component library for Jetpack Compose (primary), Flutter (secondary) and limited web. Includes token system, layout scaffolds, responsive window size classes, accessibility, and a MD3 compliance audit.
Use when an app has to move onto a design system that already exists, such as "migrate the app to our design system", "move every screen onto the new components", a rollout, or an adoption audit. Not for making the system or for swapping raw values for tokens, which are build-design-system.
Design the server-side API surface that an ObjectStack runtime exposes — REST endpoints, auth providers, realtime channels, error envelopes, batch contracts. Use when the user is adding `*.endpoint.ts`, configuring auth providers, defining custom routes, or extending the REST generator. Do not use for: consuming an ObjectStack API from a client (that is just standard HTTP — no skill needed); the auto-generated CRUD endpoints (those follow from objectstack-data); request-side query syntax (see objectstack-query). CEL expressions in route guards or auth predicates: load objectstack-formula alongside.
Author ObjectStack UI metadata — Views (list/form/kanban/calendar/gantt), Apps (navigation), Pages (structured plus the HTML and React source-authoring tiers, ADR-0080/0081), Dashboards, Reports, Charts, Actions, and package Docs (`src/docs/*.md`). Use when the user is adding `*.view.ts` / `*.page.ts` / `*.app.ts` / `*.dashboard.ts` / `*.report.ts` / `*.dataset.ts` / `*.action.ts` / `src/docs/*.md` files or designing a Studio-rendered UI surface. Do not use for: data schema (see objectstack-data), multi-step flows that BRANCH on logic between steps (those are `*.flow.ts` with `type: 'screen'` — see objectstack-automation; a stepped form over ONE object is this skill's `formViews` `type: 'wizard'`), or Studio's own admin UI (that ships with the platform). CEL expressions in visibility/conditional rules: load objectstack-formula alongside.
Interact with Obsidian vaults using the Obsidian CLI to read, create, search, and manage notes, tasks, properties, and more. Also supports plugin and theme development with commands to reload plugins, run JavaScript, capture errors, take screenshots, and inspect the DOM. Use when the user asks to interact with their Obsidian vault, manage notes, search vault content, perform vault operations from the command line, or develop and debug Obsidian plugins and themes.
Deep-dive Textual (Python) TUI skill: built-in widgets, layout systems, TCSS styling, reactive programming, background workers, multi-screen navigation, modal dialogs, and testing via the Pilot API. Covers common pitfalls and thread-safety rules for async/worker patterns, with working example apps.
Local and CI companion to the AI Diff Reviewer GitHub Action (DailybotHQ/ai-diff-reviewer). Routes to six capabilities: (1) review the current branch diff locally (same methodology as CI); (2) generate repo-tailored .review/extension.md overrides (generate-extension); (3) install and configure the Action, and answer action.yml input questions (setup); (4) author a documented pull request from the branch diff (open-pr); (5) read the CI review and walk findings to apply, defer, or skip — read-only (apply-review); (6) close the loop in one invocation — resolve the CI review findings (commits and pushes), repair the PR's other failing workflows (codecheck, tests, branch not up to date), and re-arm the reviewer per the repo label configuration (address-review). Auto-detects .review/extension.md. Use when the developer asks to review changes, customize the reviewer, set up the Action, open a PR, read the CI review, close the review loop (resolve, re-trigger, arm an unreviewed PR), or fix failing PR workflows
Builds carousels with @blossom-carousel/web custom elements in plain HTML or any framework without a dedicated package, covering npm and CDN setup, CSS scroll-snap layouts, blossom-prev/blossom-next/blossom-dots/blossom-dot controls, renderDot for per-slide dots, element methods (prev, next, goTo), and command and overscroll events. Use when a project uses <blossom-carousel> or @blossom-carousel/web, or when the user wants a Blossom carousel in static HTML, a CMS template, Astro, Rails, Django, Laravel, or another setup without a React, Vue, or Svelte component
Generate working code that routes HTTP requests through Bright Data proxy networks (Datacenter, ISP, Residential, Mobile) and help users decide which network and IP pool type to use (shared pool, shared IPs, or dedicated IPs). Use this skill whenever the user mentions Bright Data, brightdata.com, BD proxies, brd.superproxy.io, geo.brdtest.com, a brd-customer- proxy username, a Bright Data zone, the superproxy host, or wants to scrape or route requests through Bright Data—including questions about proxy URL format, country or session or IP or sticky-session targeting, SSL certificate setup for residential or mobile proxies, KYC verification, ignoring SSL errors, choosing between shared pool and shared IPs and dedicated IPs, or integrating Bright Data into Python requests/httpx/aiohttp, Node fetch/axios, Playwright, Puppeteer, Selenium, or Scrapy.
Helps developers integrate the Channel3 API for product search (text, image, semantic, and agentic), “more like this” recommendations, multi-merchant offer comparison, URL-to-product lookup, conversational shopping agents, live price and availability webhooks (product subscriptions), price history, click/transaction reporting, and affiliate commissions. Channel3 is a universal product catalog with TypeScript and Python SDKs plus a React component library (shadcn registry). Use when writing integration code, building shopping features or AI shopping agents, migrating to Channel3 SDK 4.0, or when the user mentions alternatives like Shopify Storefront API, Algolia, Amazon PA-API, or web scraping for product data.
Use to write one component's documentation entry from its code, stories and real call sites, such as "document the button", "write docs for Select", "what states does Toast have", or usage rules for a new or changed component. Not for foundations or pages that span components, which no skill here writes, nor for changing the component, which is build-design-system.
Comprehensive guide for building full-stack applications with Convex and TanStack Start. This skill should be used when working on projects that use Convex as the backend database with TanStack Start (React meta-framework). Covers schema design, queries, mutations, actions, authentication with Better Auth, routing, data fetching patterns, SSR, file storage, scheduling, AI agents, and frontend patterns. Use this when implementing features, debugging issues, or needing guidance on Convex + TanStack Start best practices.
Drive the full lifecycle of a custom Flex Gateway policy with the Policy Development Kit (PDK) — verify prerequisites, scaffold the project, edit the gcl.yaml schema, build the WebAssembly artifact, exercise it locally with the Docker playground, then publish a dev version and cut a release to Anypoint Exchange. Use this skill whenever the user mentions PDK, Flex Gateway custom policies, `anypoint-cli-v4 pdk`, `cargo anypoint`, `make build` / `make publish` / `make release`, the `wasm32-wasip1` target, or asks to "create a custom policy", "scaffold a PDK project", "build a Flex Gateway policy", "publish a policy to Exchange", "test my policy locally", "upgrade PDK", or troubleshoots a PDK build / publish / release failure — even if they don't use the word "PDK" explicitly.
Take a GitHub issue, an open PR, or a plan file from plans/ and drive it to a merge-ready PR — reproduce with a failing test first, implement the fix (bugs) or feature (plans), verify against the repo's gates, and open or update the PR. Use when asked to fix an issue, implement or execute a plan, finish or land an open PR, or work through plans/issues/.
Use when accelerating existing genomics workflows with NVIDIA Parabricks, improving runtime or price/performance, converting pipeline steps to GPUs, or comparing CPU and GPU workflow outputs. Adds optional GPU steps in-place with runtime toggles (default off). Do NOT use for individual pbrun command routing — use parabricks.
Git workflow for conventional commits, pull request creation, and pull request merging. Use when committing, opening or pushing a pull request, or merging one. Not for code review, acceptance-criteria checks, general branch management, or session wrap-up.
Godot expert auditor: Aurelius. Exhaustive never-list enforcement and architectural slap-down for Godot 4.7 projects. Use when auditing signal decay, ObjectDB orphans, typed Array/Dictionary slop, material.duplicate batch breaks, export case-sensitivity, Expression.execute risks, or sector never-lists. Keywords: auditor, Aurelius, never-list, signal decay, ObjectDB orphans, typed Array, export case-sensitivity, instance uniforms, PackedScene.get_state.
Handle Hotwire form workflows: form submission lifecycle, inline editing, validation errors, typeahead/autocomplete, modal forms, and external form controls. Prefer this skill when the core problem is correctness and UX of form interaction. Use hwc-navigation-content for pagination/tabs/filter navigation, hwc-realtime-streaming for WebSocket/Turbo Stream broadcasting, hwc-media-content for image/video/audio behavior, hwc-ux-feedback for generic loading/transition polish, and hwc-stimulus-fundamentals for framework-level Stimulus APIs not tied to forms.
This skill has instructions to setup a Envio HyperIndex indexer to capture onchain smart contract events. Use when user wants a historical feed or activity feed or some similar tracking feed or feature in their app or wants to capture onchain smart contracts events as a trigger to perform some other actions in their app. Also use this skill when the user wants to debug, restart, promote or delete and existing Envio indexer deployed on Envio Cloud
Loads all 22 DataHub connector golden standards into context. Use before starting connector development or review work to ensure the full set of standards is available for reference. Triggers on: "load standards", "show standards", "what are the connector standards", "load golden standards", "review standards", or any request to load DataHub connector development guidelines.
Primes the agent with focused understanding of the frontend portion of the codebase — components, routing, state management, and styling — without loading unrelated backend code. Use at the start of a session when the work is scoped to UI or client-side features. Optionally pulls external task context from Jira issues and Confluence pages first.
Set up your project's global rules, a lean and well-structured root CLAUDE.md (plus a starter .claude/), following the course methodology. Greenfield: pass your PRD and/or architecture-spec path and it derives rules from your engineering decisions (a PRD alone is product context). Brownfield: leave it blank to derive from your primed codebase (run /prime-codebase first), or pass a codebase-analysis doc for a large repo. Use when initializing or re-deriving the AI Layer's rules, onboarding a codebase, or replacing a generic /init output. The customizable replacement for /init.
Write correct Sarvam Bulbul TTS code — bulbul:v4-flash persona speaker IDs (voice_language_style), REST, HTTP stream, WebSocket, pronunciation dictionaries, and v3/v4 traps (short names rejected on v4, param ranges). Use this skill when generating speech in an app with Python or JS/TS. For live TTS in chat via MCP, use sarvam-mcp instead.
