We need to produce 2-3 sentence plain-text summary, objective, factual, no marketing language, no superlatives, no calls to action, no bullet points, no headings, no markdown. At most 60 words. Must be plain text, no quotes. Should explain what the skill does, what problem it solves, when to use it. Use objective tone. No superlatives like "best", "widely considered". Must avoid marketing language. So we can say: "The skill provides access to Anthropic Claude AI models for tasks such as code analysis, long‑document processing, and safe interaction with external data.
Claude
Claude (by Anthropic) is OpenAI's main competitor. It is famous for its large context window (200k+), low hallucination rates, and "Artifacts" UI.
When to Use
- Coding: Claude 3.5 Sonnet is widely considered the best coding model in 2025.
- Long Context: Analyzing massive PDFs or codebases.
- Safety: Enterprise-grade safety guardrails.
Core Concepts
Models
- Opus: The smartest, largest model.
- Sonnet: The sweet spot. Fast and incredibly capable.
- Haiku: Fast and cheap.
Artifacts
A UI feature (now an API pattern) where the model generates standalone content (React components, SVGs) in a side window.
Computer Use
Claude can interact with a computer GUI (moving mouse, clicking) via API.
Best Practices (2025)
Do:
- Use Sonnet for Dev: It beats GPT-4o in many coding benchmarks.
- Use XML Tags: Claude loves
<instructions>and<context>tags in prompts. - Prefill Responses: Guide Claude by prefilling the
{"role": "assistant", "content": "{"}to force JSON.
Don't:
- Don't ignore System Prompts: Claude relies heavily on strong system instructions.
