Comprehensive UI and UX design principles for software development. This skill should be used when designing interfaces, implementing user interactions, ensuring accessibility, optimizing performance, and creating responsive layouts. Triggers on tasks involving UI components, user experience flows, accessibility requirements, responsive design, or design system implementation.
Verify device legitimacy and app integrity using DeviceCheck (DCDevice per-device bits) and App Attest (DCAppAttestService key generation, attestation, and assertion flows). Use when implementing fraud prevention, detecting compromised devices, validating app authenticity with Apple's servers, protecting sensitive API endpoints with attested requests, or adding device verification to your backend architecture.
Implement iOS authentication patterns including Sign in with Apple (ASAuthorizationAppleIDProvider, ASAuthorizationController, ASAuthorizationAppleIDCredential), credential state checking, identity token validation, ASWebAuthenticationSession for OAuth and third-party auth flows, ASAuthorizationPasswordProvider for AutoFill credential suggestions, and biometric authentication with LAContext. Use when implementing Sign in with Apple, handling Apple ID credentials, building OAuth login flows, integrating Password AutoFill, checking credential revocation state, or validating identity tokens server-side.
Access and operate Gmail directly from scripts. Supports multiple accounts (link, list, unlink). Read inbox, search emails, read threads, reply with HTML/attachments/CC/BCC, send emails, manage labels, and manage drafts. On first use, runs an OAuth2 auth flow. Use when the user wants to read, search, reply, send, label, draft emails, or manage multiple Gmail accounts.
Address tracker and analysis. Use this skill whenever the user provides an on-chain address or asks to track or query an address. Trigger phrases include: track this address, who owns this address, fund flow, check address. MCP tools: info_onchain_get_address_info, info_onchain_get_address_transactions, info_onchain_trace_fund_flow.
Craft elegant technical specifications with ASCII artistry, flow diagrams, and the Grove voice. The swan glides with purpose—vision first, then form, then perfection. Use when creating specs, reviewing documents, or transforming technical plans into storybook entries.
Is smart money exiting a token I hold? Net flow direction, seller breakdown by label, and recent SM trades.
Machine Payment Protocol (MPP) for keyless, pay-per-query access to the Codex Supergraph GraphQL API. Use when the user has no API key and wants to pay per query via the 402 challenge flow at https://graph.codex.io/graphql.
OmniStudio OmniScript creation and validation with 120-point scoring. Use when building guided digital experiences, multi-step forms, or interactive processes that orchestrate Integration Procedures and Data Mappers. TRIGGER when: user creates OmniScripts, designs step flows, configures element types, or reviews existing OmniScript configurations. DO NOT TRIGGER when: building FlexCards (use sf-industry-commoncore-flexcard), creating Integration Procedures directly (use sf-industry-commoncore-integration-procedure), or analyzing dependencies (use sf-industry-commoncore-omnistudio-analyze).
Help the user shape technical blog posts, website articles, devlogs, essays, or long-form drafts without writing the full post for them. Use this whenever the user shares rough notes, a brain dump, unordered ideas, bullet points, or half-written sections, or asks for help turning notes into an outline, finding the angle, sharpening the hook or thesis, improving structure, clarifying the argument, tightening flow, stress-testing the payoff, or making a technical piece more engaging while preserving their voice. Use it even if the user does not explicitly ask for a writing guide, as long as they need help organizing and developing a post rather than having it ghostwritten. Guide with organization, critique, focused questions, and tiny example lines only; do not write the final article.
Use this skill when users mention scenarios such as "Feishu authorization", "OAuth", "Device Flow", "open_id", "repeated authorization pop-ups", "token reuse", "supplement authorization scopes", or "where Feishu tokens are stored"—scenarios that require reusing existing local user tokens, only supplementing missing scopes, or troubleshooting the actual storage location of tokens.
Integrate Apple Music playback, catalog search, and Now Playing metadata using MusicKit and MediaPlayer. Use when adding music search, Apple Music subscription flows, queue management, playback controls, remote command handling, or Now Playing info to iOS apps.
