Reusable SKILL.md capabilities that give your agent new expertise — installed into .claude/skills/ and friends.
Fetch real-time and historical financial data using ticker-cli. Use when the conversation mentions stock prices, crypto, forex, commodities, indices, market data, portfolio checks, weekly reports, or price verification. Triggers on "what's AAPL at", "check BTC price", "how did gold do this week", "get me the YTD", "price of", "market update", "how much is", "cours de", "prix du bitcoin".
Query AI model specifications, pricing, and capabilities from models.dev database. Use when users ask about AI model parameters (context window, token limits, cost per token), model comparisons, provider information, or need to look up specific model IDs for AI SDK integration. Triggers on queries like "What's the context window for GPT-4o?", "Compare Claude vs GPT", "How much does Gemini Pro cost?", "List OpenAI models", or "What models support tool calling?".
OpenAI API integration for building AI-powered applications. Use when working with OpenAI's Chat Completions API, Python SDK (openai), TypeScript SDK (openai), tool use/function calling, vision/image inputs, streaming responses, DALL-E image generation, Whisper audio transcription, text-to-speech, embeddings, Assistants API, fine-tuning, or any OpenAI API integration task. Triggers on mentions of OpenAI, GPT-4, GPT-4o, GPT-5, o1, o3, o4, DALL-E, Whisper, Sora, or OpenAI SDK usage.
Use this skill when writing code that uses the canopy-i18n package — a type-safe, zero-dependency i18n library with a builder pattern API. Covers createI18n, add (static and template), build, bindLocale, React integration, and common gotchas like required `as const`.
Manage git worktrees with iTerm2 integration. Use when user asks to create isolated development environments, work on features in parallel, manage worktrees, open worktrees in new tabs/windows, switch between worktrees, or close completed worktrees. Triggers on "create worktree", "new worktree", "feature branch with worktree", "open worktree", "switch worktree", "close worktree", "list worktrees", or mentions wanting to work on multiple features simultaneously.
