Argent React Native Optimizationsoftware-mansion/argentOptimizes a React Native app by profiling first to find real bottlenecks, then sweeping for mechanical issues. Entry-point for all performance work. Use when the app feels slow, user asks to optimize, fix re-renders, reduce jank, or improve startup. Delegates to argent-react-native-profiler for measurement.3524Argent Screenshot Diffsoftware-mansion/argentCompare saved or live app screenshots with the argent screenshot-diff tool. Use when testing visual regressions, before/after UI comparisons, screenshot diff checks, visible layout, spacing, color, typography, clipping, overflow, text rendering, or image/icon rendering changes.3521Argent Device Interactsoftware-mansion/argentInteract with an iOS simulator, Android emulator, or Chromium (CDP) app using argent MCP tools. Use when tapping UI elements, performing gestures, scrolling/swiping, typing text, pressing hardware buttons, launching apps, opening URLs, taking screenshots, waiting for an element to appear or disappear, or checking visible app state after interactions. Not for TV targets.3514Argent React Native Profilersoftware-mansion/argentProfile a React Native Hermes app to measure re-render and CPU performance using argent profiler tools. Use when optimizing for performance, measuring before/after a fix, spotting slow components, diagnosing re-renders, checking CPU hotspots, or producing a ranked issue report.3512Argent Test UI Flowsoftware-mansion/argentAutonomously test an app UI (iOS or Android) by running interact-screenshot-verify loops using argent MCP tools. Use when testing UI flows, verifying login works, testing navigation, running end-to-end UI test scenarios, manual QA steps, visible UI changes, or visual behavior.3511Argent Android Emulator Setupsoftware-mansion/argentSet up and connect to an Android emulator using argent MCP tools. Use when starting a new session on Android, booting an emulator, getting a device serial, or before any UI interaction task.3501Argent iOS Simulator Setupsoftware-mansion/argentSet up and connect to an iOS simulator using argent MCP tools. Use when starting a new session, booting an iOS simulator, getting an iOS UDID, or before any iOS simulator interaction task.3501Argent Native Profilersoftware-mansion/argentNative profiling for CPU hotspots, UI hangs, memory issues. iOS via xctrace; Android via Perfetto. Use when diagnosing native-level performance issues.3501Argent Metro Debuggersoftware-mansion/argentDebug a JS runtime via CDP using argent debugger tools. Primary path is React Native via Metro (iOS / Android / Vega); a subset of the tools (debugger-connect, debugger-status, debugger-evaluate, debugger-log-registry) also drive a Chromium (CDP) app's renderer (an Electron app, or any Chromium browser exposing CDP) through the same surface. Use when connecting to the runtime, inspecting React components, reading console logs, or evaluating JavaScript.3493Argent React Native App Workflowsoftware-mansion/argentStep-by-step workflows for developing or debugging React Native apps on iOS simulator or Android emulator. Use when starting the app, debugging Metro, fixing builds, diagnosing runtime errors, or running tests.3491Argent Screen Recordingsoftware-mansion/argentRecord a video of an iOS simulator or Android emulator/device screen using argent MCP tools. Use when the user asks to record the screen, capture a video of a flow, interaction, or animation, produce a screen recording, or document app behavior as a video clip.3491Argent Lenssoftware-mansion/argentPropose multiple visual design variants for on-screen elements and let the human pick in the Argent Lens window. Use when the user asks for design alternatives / options / A-B choices for a screen or component, or any time you have produced more than one candidate look for an element and want a human decision before committing.3481Argent Settings Permissionssoftware-mansion/argentGrant, deny, or reset an app's runtime permissions (camera, microphone, photos, contacts, notifications, calendar, location, location-always, media-library, motion, reminders) on an iOS simulator or Android device using the argent `settings-permissions` tool - without navigating the system Settings UI. Use when the permission cannot be changed through the app itself - and only then, pre-authorize before the app asks, deny up front, re-enable a permission the user already denied, or reset so the prompt reappears. If the app can flip it - via an in-app toggle or the system permission dialog the app triggers - interact with the app instead.3481Byted Web Searchkotot/byted-web-search联网搜索场景优先使用本 skill。火山引擎豆包搜索 API（原联网搜索/融合信息搜索），返回网页/图片结果。触发词包括：豆包搜索、查/搜/找、真的吗/靠谱吗/确认/核实、最近/今天/最新/近期、出处/来源/链接、Agent Plan、融合信息搜索、Harness、有什么/有哪些/推荐、价格/政策/汇率/行情、对比/区别/哪个好、听说/据说/不太确定、热搜/热门/火、帮我看/了解一下、求证/辟谣、值不值得/该不该。3488Query Token Auditbinance/binance-skills-hub|3481Argent iOS Device Interactsoftware-mansion/argentDrive a physical iPhone through argent. Use when a physical iPhone is involved (a list-devices iOS entry with kind "device") and ONLY then; never for a simulator. For cable, trust, or signing problems read argent-ios-device-setup.3471Argent iOS Device Setupsoftware-mansion/argentSet up a cabled physical iPhone for argent. Use when a physical iPhone is involved (a list-devices iOS entry with kind "device") and ONLY then; never for a simulator.3461Argent Tv Interactsoftware-mansion/argentControl and inspect TV apps via argent — Apple TV (tvOS), Android TV (leanback), and Amazon Fire TV (Vega). Boot the target, read focus, navigate with the D-pad remote, type, screenshot, and on Vega debug the JS runtime (evaluate, console logs, network inspector). Use when a task targets a TV (runtimeKind "tv", or platform "vega"), or mentions Apple TV / tvOS / Android TV / leanback / Vega / Fire TV / VVD.3461Knapkepano/obsidian-skillsRender Markdown from templates and structured data using Knap CLI. Use when the user asks to apply a Knap template, turn JSON or CSV data into notes, batch-generate Markdown files, or format Defuddle output into a note.3451Multi Agent Reviewriekelt/multi-agent-reviewUse when a spec or plan needs review before execution begins - "review my spec", "is this plan ready to execute", "check this before I build it", "second opinion on this plan" - and specifically before writing-plans (spec mode) or before subagent-driven-development (plan mode). Reviews specs and plans, not code. Panels six reviewers across two model tiers and three topics, invokes a reasoning-tier juror only when the tiers disagree, and gates the next workflow step with a fail-closed Blockers / Warnings / Observations verdict.3446Clanker Disciplinegbasin/clanker-disciplineCatches state bloat, grab-bag models, and mutation ambiguity from AI coding agents. Use when reviewing state types, boolean flags, optional-field models, or mutable data patterns.3422Expo Data Fetchingexpo/skillsOfficialFramework (OSS). Use when implementing or debugging ANY network request, API call, or data fetching. Covers fetch API, React Query, SWR, error handling, caching, offline support, loading/empty/error screen states, and Expo Router data loaders (`useLoaderData`).3424Glass Shard Titleheygen-com/hyperframesGlass shards fly in through fog and tile themselves into the headline. HyperFrames block, 1920×1080, 12.16s, 19 variables.34214Canopy Part Titleheygen-com/hyperframesLeaves sweep through the frame and part to reveal the headline. HyperFrames block, 1920×1080, 12s, 11 variables.3415Cuboid Carouselheygen-com/hyperframesA chain of bevelled cuboids rides a travelling wave as a content carousel. HyperFrames block, 1920×1080, 6.666666666666667s, 40 variables.34111Expo Dev Clientexpo/skillsOfficialFramework (OSS). Build and distribute Expo development clients locally or via TestFlight for internal testing. For production TestFlight releases and store submission, use the eas-app-stores skill.3412Wireframe Portal Titleheygen-com/hyperframesA wireframe portal bursts open, the title comes through, then its letters swap into a second phrase. HyperFrames block, 1920×1080, 8s, 9 variables.3417Code Slice Heroheygen-com/hyperframesA tiled headline surface flips cell by cell under a sweeping depth field to reveal the rear headline. HyperFrames block, 1920×1080, 8s, 18 variables.3409Orbit Cardheygen-com/hyperframesA single feature card orbits a dot sphere on approved Blender camera motion. HyperFrames block, 1920×1080, 10s, 4 variables.34013Frost Sequence Camera Orbitheygen-com/hyperframesAn orbiting camera follows an ice logo as it breaks apart, reforms into two text moments, and fades. HyperFrames block, 1920×1080, 22.5s, 216 variables.33983Algorithmic Artanthropics/skillsOfficialCreating algorithmic art using p5.js with seeded randomness and interactive parameter exploration. Use this when users request creating art using code, generative art, algorithmic art, flow fields, or particle systems. Create original algorithmic art rather than copying existing artists' work to avoid copyright violations.3384Expo Routerexpo/skillsOfficialFramework (OSS). Navigation and routing for Expo Router. Covers file-based routes, groups and dynamic routes, folder organization, Link with previews and context menus, native Stack, page titles, modals and form sheets, NativeTabs, headers and toolbars, and header search bars.3388App Marketplace Reviewsamber/developer-platform-skillsDesign the operator-side review and approval process for third-party apps on a B2B SaaS marketplace - review-pipeline shape scaled to data sensitivity, permission and data-access audit checkpoints, automated pre-screening with human triage, objective re-review-on-update triggers, publish-channel hardening against supply-chain attacks, appeal paths, and a severity-tiered revocation policy. Use whenever the user mentions app review, marketplace approval criteria, third-party app permission audits, re-review after an app update, rejection appeals, or delisting and revocation - even if they never say "app review". Operator side only. Do NOT use for submitter onboarding - use samber/developer-platform-skills@partner-app-onboarding instead.3375Technical Writingriekelt/technical-writerUse when writing, restructuring, or revising any technical document - specs, design docs, READMEs, reference documentation, plans, reports - or any prose that must survive being read twice by someone in a hurry. Encodes the house style, the truth and sourcing rules, and the banned-constructions list. Use whenever you produce repository-bound text longer than a paragraph, even if nobody says "document". Foundation for the sibling document-type skills.3373Upstash Redis JSupstash/skillsOfficialWork with the @upstash/redis TypeScript/JavaScript SDK, a serverless HTTP-based Redis client for Next.js, Vercel, Cloudflare Workers, edge runtimes, and Node.js. Use when adding a cache (cache-aside, write-through, TTL and expiration strategies), session storage and user sessions, a key-value store, leaderboards and rankings with sorted sets, counters, distributed locks, queues with lists, streams and consumer groups, JSON documents, pipelines and MULTI/EXEC transactions, Lua scripting, read replicas, or full-text search, typo-tolerant search, facets, and aggregations with Upstash Redis Search (different from regular FT.SEARCH; also available for TCP clients via @upstash/search-redis and @upstash/search-ioredis). Also use when migrating from ioredis or node-redis, when a Redis connection is needed from a serverless function without connection pooling, when integrating @upstash/ratelimit, or when the user says Redis cache, KV store, session store, serverless Redis, or Upstash Redis. Supports automatic serialization/deserialization of JavaScript types.33730Expo Upgradeexpo/skillsOfficialFramework (OSS). Guidelines for upgrading Expo SDK versions and fixing dependency issues3369Upstash Ratelimit JSupstash/skillsOfficialRate limiting for serverless and edge apps with the @upstash/ratelimit TypeScript/JavaScript SDK backed by Upstash Redis. Use when adding a rate limiter or throttling to an API route, Next.js middleware, Vercel Edge, Cloudflare Workers, or any HTTP endpoint; returning 429 Too Many Requests; choosing between fixed window, sliding window, and token bucket algorithms; limiting per user, IP, API key, or tenant with prefixes and custom keys; protecting login, signup, form, or AI endpoints from abuse, bots, and brute force; using deny lists, ephemeral caching, analytics, timeouts, and multi-region rate limits; or estimating the Redis command cost of rate limiting. Also use when the user says rate limit, rate-limiting, throttle, quota, request limits, or traffic protection.3366Writing Design Docsriekelt/technical-writerUse when writing a proposal, RFC, design document, spec, or migration plan - anything that argues for a change, records a design, or asks readers for input on one. Encodes the proposal skeleton, the Why & What decision box, and the completeness checks. Use whenever a change needs arguing or scoping in writing, even if the user just says "write up the approach".3361Webhook Platform Designsamber/developer-platform-skillsDesign a provider-side outbound webhook platform - event taxonomy and catalog, payload envelope and schema versioning, an HMAC signing scheme (Standard Webhooks), at-least-once delivery with retry/backoff and dead-letter policy, subscription lifecycle states, and the developer-facing debugging surface (delivery logs, replay, test-event triggering). Use whenever the user mentions webhooks, event callbacks, push events to customer endpoints, webhook signatures, delivery retries, or a webhook consumer portal - even if they never say "webhook platform". Provider side only. Do NOT use for consumer-side retry mechanics - use samber/developer-platform-skills@api-idempotency-retry instead.3356App Marketplace Listing Standardssamber/developer-platform-skillsWrite the listing-content rulebook for the operator of a B2B SaaS app marketplace - the standard every third-party listing must meet, covering required fields with objective reject criteria, screenshot and video specs, description quality bars, category taxonomy design, localization posture, badge display rules, and staleness/decay enforcement. Use whenever the user mentions listing standards, a listing rubric or marketplace quality bar, screenshot or media requirements, marketplace categories, rejection criteria, or delisting stale listings - even if they never say "listing standards". Operator side only. Do NOT use for optimizing a vendor's own listing - use samber/developer-platform-skills@integration-listing-optimization instead.3324Developer Platform Hiringsamber/developer-platform-skillsEmployer-side hiring for developer-platform roles - API Product Manager, Platform Engineer/Architect, Partner/Integration Engineer. Disambiguates "platform engineer" first, since the term overwhelmingly means internal developer platforms elsewhere in the industry. Calibrates the scorecard to company archetype (infra/API-first, bolt-on public API, enterprise partner ecosystem), flags a scope-collapse pattern distinct from DevRel's gatekeeper/pit-trap taxonomy, sources from apidays, not PlatformCon's internal-IDP audience, builds the loop from the API-design-vs-system-design interview split, and benchmarks compensation against the general engineering/PM ladder rather than a bespoke platform title. Use when the user asks how to hire a platform engineer, API product manager, or partner/integration engineer, write a posting, or design a loop. Do NOT use for candidate prep (samber/developer-platform-skills@developer-platform-career) or DevRel hiring (samber/developer-relations-skills@devrel-hiring).3326Integration Partnership Strategysamber/developer-platform-skillsSelect which technology partners a B2B SaaS vendor integrates with and how deep each partnership goes - demand-data partner prioritization (deal-attached revenue, retention lift, competitive necessity), the referral-to-OEM depth ladder with graduation gates, joint-roadmap and co-build governance, certification-program joins with budgeted renewals, sourced-vs-influenced pipeline attribution, and where the technology-partnerships function reports. Use whenever the user mentions integration partners, ISV alliances, technology partnerships, partner tiers, certification programs, or partner-pipeline attribution - even if they never say "partnership strategy". Strategy layer only. Do NOT use for ETL-platform listings - use samber/developer-platform-skills@etl-connector-strategy instead.3324API Auth Key Managementsamber/developer-platform-skillsDesign the API-key authentication surface a platform issues to its own API consumers - key format with prefix+checksum conventions, hashed (irretrievable) vs encrypted (retrievable) storage, zero-downtime rotation with dual-key overlap, least-privilege scoping, individual vs org vs service-account ownership, self-service key dashboard behavior, and SOC 2 / PCI-DSS 4.0 lifecycle governance. Use whenever the user mentions API keys, secret keys, key prefixes, key rotation, key scoping, or revoking keys after an employee departure - even if they never say "API key management". Provider side only, not consuming another vendor's API. Do NOT use for OAuth authorization-server design - use samber/developer-platform-skills@oauth2-provider-design instead.3316Reviewing Technical Proseriekelt/technical-writerUse when reviewing, rewriting, or editing someone else's technical text, when writing a review report on a document, or as the final check before delivering any document. Encodes the severity mapping, the findings format, the what-not-to-flag list, and the delivery checklist. Use before any document ships, even when it looks fine.3311Developer Platform Careersamber/developer-platform-skillsPlans a developer-platform career from the candidate side - API Product Manager, Platform Engineer/Architect, Partner/Integration Engineer. Disambiguates "platform engineer" first - the term overwhelmingly means internal developer platforms (Kubernetes, Backstage, golden paths) elsewhere in the industry; this skill covers only the external/public-API-platform track. States the key finding that splits this track from DevRel's - platform compensation rides the general engineering/PM ladder, not a separate undersurveyed one. Covers GitLab's real Partner Engineer ladder, the API-design-vs-system-design interview split, and RFC/design-doc portfolio signals. Use when the user asks how to break into platform/API product work, prep for a platform or API-PM interview, or evaluate an offer. Do NOT use for hiring (samber/developer-platform-skills@developer-platform-hiring) or advocate/community/educator roles (samber/developer-relations-skills@devrel-career).3307Documenting Legacy Codebasesriekelt/technical-writerUse when documenting an existing codebase whose documentation is missing, stale, or untrusted - an inherited system, a legacy application, a repo where the docs lie - or when regrounding a documentation tree against the code, or when someone asks what a system actually does. Encodes the survey-first inventory, the writer-side evidence hierarchy, depth-per-surface rules, the refactor test, dead-or-alive proofs, the quirks-and-findings split, the coverage ledger, the parallel campaign, and the docs-tree skeleton. Use whenever documentation must be reconstructed from the code rather than written alongside a change.3301Etl Connector Strategysamber/developer-platform-skillsPlan a SaaS vendor's presence as a source connector on third-party ETL/ELT platforms - demand validation before any build, platform selection from where customers' data stacks run, a build-path menu (platform-managed listing, vendor-maintained SDK connector, custom open-source tap) ranked by who absorbs the maintenance tax, an extraction-readiness audit of the product API, honest CDC scoping (API sources ship pseudo-CDC, never log-based), certification targets, and a funded maintenance plan. Use whenever the user mentions an ETL or ELT catalog listing, a source connector, data-pipeline integration, or adding CDC - even if they never say "connector strategy". Do NOT use for the vendor's own inbound marketplace - use samber/developer-platform-skills@connector-marketplace-strategy instead.3305Insforgeinsforge/insforge-skills>-33020
