Master iOS Human Interface Guidelines and SwiftUI patterns for building native iOS apps. Use when designing iOS interfaces, implementing SwiftUI views, or ensuring apps follow Apple's design principles.

Orchestrate an editorial review for pull requests targeting dev. Reviews changed markdown files and posts a structured comment to the PR. Vale and Dale issues are auto-fixed separately by the vale-autofix workflow. Use this skill whenever a PR involves markdown files in docs/ and targets the dev branch — triggered automatically by the doc-pr GitHub Actions workflow on PR open, sync, or when invoked manually via /doc-pr.

Helps create, configure, and deploy Azure Static Web Apps using the SWA CLI. Use when deploying static sites to Azure, setting up SWA local development, configuring staticwebapp.config.json, adding Azure Functions APIs to SWA, or setting up GitHub Actions CI/CD for Static Web Apps.

Create distinctive, production-grade frontend interfaces with high design quality. Use this skill when the user asks to build web components, pages, artifacts, posters, or applications. Generates creative, polished code that avoids generic AI aesthetics.

Answer questions about live production system behavior — current variable values, execution durations, hit counts, and value distributions — by instrumenting running services with Lightrun MCP tools. Use when the question requires live runtime data rather than static code analysis (e.g. "show recent requests to this endpoint", "show the runtime distribution for this operation", "what values appear for this expression in production?", "which branch runs for customer X?"). Do not use for incident diagnosis, pull-request review, code changes, setup, or deployment. Route latency, timeout, deadline, SLO, or hang diagnosis to lightrun-slow-execution-diagnosis when available; route other diagnosis, or fallback when that skill is unavailable, to lightrun-live-runtime-debugging when available. If neither diagnosis skill is available, report the scope gap.

Detect flaky tests from CI history and propose LLM-validated fixes via quarantine pull requests. Use to find flaky tests, analyze CI test stability, identify tests that flip pass/fail without code changes, or set up automated quarantine workflows. Supports any test framework that emits JUnit XML (pytest, unittest, JUnit, TestNG, Vitest, Jest with junit reporter). Trigger when users mention "flaky tests", "intermittent failures", "tests that randomly fail", "quarantine flaky tests", "CI flakiness", or ask to "find unreliable tests", "analyze CI history", "mark tests as flaky".

Guides snapshot mode selection, capture workflows, QA sharing, and team setup for Jahro Snapshots. Use when the user mentions snapshots, bug capture, sharing logs, streaming, recording, QA workflow, team collaboration, or wants to share debugging sessions with their team.

Migrate to Juicebox from other tools. Trigger: "switch to juicebox", "migrate to juicebox".

The framework-agnostic Stream builder (Steps 0-7 scaffold + enhance + Video audit), being extended to support app kinds beyond web. Use ONLY when the user explicitly names 'stream-builder' or '/stream-builder'. Web React / Next.js work - 'build me a chat app', 'scaffold', 'create a new ...', 'add Chat/Video/Feeds to this app', 'integrate Video', livestreaming, video conferencing, team messaging, direct messaging, social feed - defaults to the stream-react skill, not this one. Not auto-selected for generic web build requests.

Upgrade Evernote SDK versions and migrate between API versions. Use when upgrading SDK, handling breaking changes, or migrating to newer API patterns. Trigger with phrases like "upgrade evernote sdk", "evernote migration", "update evernote", "evernote breaking changes".

Diagnose and resolve common Documenso API errors and issues. Use when encountering Documenso errors, debugging integration issues, or troubleshooting failed operations. Trigger with phrases like "documenso error", "documenso 401", "documenso failed", "fix documenso", "documenso not working".

Plan and execute Deepgram SDK upgrades and model migrations. Use when upgrading SDK versions (v3 to v4 to v5), migrating models (Nova-2 to Nova-3), or planning API version transitions. Trigger: "upgrade deepgram", "deepgram migration", "update deepgram SDK", "deepgram version upgrade", "nova-3 migration".

Manage PostHog feature flags, cohorts, dashboards, and insights via the `piglet` CLI. Use when the user needs to list, create, update, or delete PostHog resources, check flag status, manage rollouts, or export configuration.

CLI to manage emails via IMAP/SMTP. Use `himalaya` to list, read, write, reply, forward, search, and organize emails from the terminal. Supports multiple accounts and message composition with MML (MIME Meta Language).

Handle user data, privacy, and GDPR compliance with Clerk. Use when implementing data export, user deletion, or privacy compliance features. Trigger with phrases like "clerk user data", "clerk GDPR", "clerk privacy", "clerk data export", "clerk delete user".

**REQUIRED** - Always activate FIRST on any git/VCS operations (commit, status, branch, push, etc.), especially when HEAD is detached. If `.jj/` exists -> this is a Jujutsu (jj) repo - raw git commands can corrupt data. Essential git safety instructions inside. DO NOT IGNORE.

React and Next.js performance optimization guidelines from Vercel Engineering. This skill should be used when writing, reviewing, or refactoring React/Next.js code to ensure optimal performance patterns. Triggers on tasks involving React components, Next.js pages, data fetching, bundle optimization, or performance improvements.

AWS CloudFormation infrastructure as code for stack management. Use when writing templates, deploying stacks, managing drift, troubleshooting deployments, or organizing infrastructure with nested stacks.
