Get current weather and forecasts via wttr.in or Open-Meteo. Use when: user asks about weather, temperature, or forecasts for any location. NOT for: historical weather data, severe weather alerts, or detailed meteorological analysis. No API key needed.

Use when the user wants to vendor or track an upstream GitHub repo as a research reference inside the current project — adds, updates, lists, or removes `research/<owner>/<repo>` git submodules pinned to the latest stable release (not main/HEAD). Invoked for upstream code reference, dependency mirroring, or research material management.

Use when the user asks for parallel team-style execution of multiple features in one project — orchestrates a team lead + N dev workers, one feature per worktree, each gated on x-qa E2E tests, with blocker escalation to human via SendMessage. Hard requires `plugin.omc` (TeamCreate/SendMessage primitives) and `.x-skills/x-qa/profile.json` (E2E gate).

Use when the user reports a bug, error, test failure, or unexpected behavior — routes through investigation, hypothesis testing, and verified fix with structured evidence collection

Create Excalidraw diagrams programmatically. Use when the user wants architecture diagrams, flowcharts, or any visual diagram with a hand-drawn aesthetic, where editable output and drag-and-drop editing add value over Mermaid's text-only approach.

AI-powered code review using CodeRabbit. Default code-review skill. Trigger for any explicit review request AND autonomously when the agent thinks a review is needed (code/PR/quality/security).

Specification generator - 7 phase document chain producing product brief, PRD, architecture, epics, and issues. Agent-delegated heavy phases (2-5, 6.5) with Codex review gates. Triggers on "generate spec", "create specification", "spec generator", "workflow:spec".

SKILL.md simplification with functional integrity verification. Analyze redundancy, optimize content, check no functionality lost. Triggers on "simplify skill", "optimize skill", "skill-simplify".

When the user wants to create AI-generated ad creative, test performance creative, manage creative fatigue, or optimize paid media with AI tools. Also use when the user mentions 'ad creative,' 'performance creative,' 'creative testing,' 'creative fatigue,' 'Meta ads,' 'Google ads,' 'TikTok ads,' 'AI ads,' 'ad budget,' 'ROAS,' 'Advantage+,' or 'Performance Max.' This skill covers AI-powered paid creative from generation through performance optimization. Do NOT use for technical implementation, code review, or software architecture.

Deploy applications to Render by analyzing codebases, generating render.yaml Blueprints, and providing Dashboard deeplinks. Use when the user wants to deploy, host, publish, or set up their application on Render's cloud platform. Do NOT use for deploying to Vercel, Netlify, or Cloudflare (use their respective skills).

When the user wants to sell through social media, optimize LinkedIn for sales, build DM sequences, or convert content engagement into pipeline. Also use when the user mentions 'social selling,' 'LinkedIn selling,' 'LinkedIn DMs,' 'social prospecting,' 'LinkedIn Sales Navigator,' 'DM sequences,' 'LinkedIn outreach,' 'social pipeline,' or 'LinkedIn optimization.' This skill covers social selling strategy from profile optimization through DM-to-deal conversion. Do NOT use for technical implementation, code review, or software architecture.

Laravel framework skill for writing, reviewing, and testing PHP applications built with Laravel. Use whenever working on Laravel-specific patterns: controllers, FormRequests, Eloquent models, service/action classes, Blade templates, jobs, events, policies, observers, or Artisan commands. Also applies to Inertia frontends (React or Vue) embedded inside a Laravel project — covering useForm, usePage, Link navigation, partial reloads, page component naming (PostsIndexPage), and shadcn wrapper conventions. Trigger any time someone mentions Laravel, Eloquent, Artisan, Blade, FormRequest, Inertia within Laravel, N+1 queries in a Laravel app, inline controller validation, where business logic should live in a Laravel controller, or asks to follow best practices in a Laravel codebase. Does not apply to plain PHP scripts without Laravel, Rails, Django, standalone Next.js, or non-Laravel frameworks.

Refactor and review SwiftUI view files with strong defaults for small dedicated subviews, MV-over-MVVM data flow, stable view trees, explicit dependency injection, and correct Observation usage. Use when cleaning up a SwiftUI view, splitting long bodies, removing inline actions or side effects, reducing computed `some View` helpers, or standardizing `@Observable` and view model initialization patterns.

Manage stickies as markdown files — create new, read, list, or delete. Use when the user mentions "sticky", "stickies", or wants to take a quick note or save a reminder.

Fetches authoritative, current, version-specific documentation and official code examples via Context7 for a named external library, framework, SDK, CLI, or cloud product. Use when the user needs exact API behavior, setup, configuration, integration, migration, or version-specific guidance rather than general web research or real-world repository patterns.

Execute read-only SQL queries against multiple PostgreSQL databases. Use when: (1) querying PostgreSQL databases, (2) exploring database schemas/tables, (3) running SELECT queries for data analysis, (4) checking database contents. Supports multiple database connections with descriptions for intelligent auto-selection. Blocks all write operations (INSERT, UPDATE, DELETE, DROP, etc.) for safety.

This skill should be used when the user says "style explore", "arn style", "visual style", "explore styles", "UI style", "look and feel", "design direction", "pick a style", "choose colors", "theme the app", "visual direction", "style guide", or wants to explore and define the visual design direction for their project through guided conversation, producing a style brief document with implementable toolkit configuration.

This skill should be used when the user says "spark help", "arn spark help", "greenfield status", "greenfield help", "where am I in spark", "what's next for spark", "spark pipeline", "spark status", "arn-spark-help", "show spark pipeline", "what step am I on for spark", "spark workflow", "exploration status", "show exploration pipeline", "how does spark work", "explain spark pipeline", or wants to see their current position in the Arness Spark exploration pipeline and get guidance on the next step.

This skill should be used when the user says "infra wizard", "arn infra wizard", "guided infra", "walk me through infrastructure", "infrastructure pipeline", "full infra pipeline", "infra flow", "run the infra pipeline", "guide me through infrastructure", "infra guided mode", "infrastructure wizard", "end to end infrastructure", "deploy everything", "set up my infrastructure", "infra start to finish", "arn infra guided", "run infra wizard", "set up everything", "complete infra setup", or wants to be walked through the entire Arness infrastructure pipeline in a single continuous session with guided decision gates instead of invoking each skill manually.

This skill should be used when the user says "review infra change", "infrastructure review", "review infrastructure", "infra quality review", "arn infra review", "check infra change", "review infrastructure change", "infra change review", "quality check infrastructure", "arn-infra-review-change", "post-deployment review", or wants to perform a comprehensive post-execution quality review of completed infrastructure changes, producing a structured review report with a PASS/WARN/NEEDS_FIXES verdict.
