Anthropic Claude AI models for analysis and coding. Use for AI assistants.

Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# 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. ## References - [Anthropic Documentation](https://docs.

How do I install it?
Run `npx skills add majiayu000/claude-skill-registry --skill claude-g1joshi-agent-skills --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From majiayu000/claude-skill-registry, a repository with 534 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
