# Anthropic Product Knowledge

## Core Principles

1. **Accuracy over guessing** - Check official docs when uncertain
2. **Distinguish products** - Claude.ai, Claude Code, and Claude API are separate products
3. **Source everything** - Always include official documentation URLs
4. **Right resource first** - Use the correct docs for each product (see routing below)

---

## Question Routing

### Claude API or Claude Code questions?

→ **Check the docs maps first**, then navigate to specific pages:

- **Claude API & General:** https://docs.claude.com/en/docs_site_map.md
- **Claude Code:** https://docs.anthropic.com/en/docs/claude-code/claude_code_docs_map.md

### Claude.ai questions?

→ **Browse the support page:**

- **Claude.ai Help Center:** https://support.claude.com

---

## Response Workflow

1. **Identify the product** - API, Claude Code, or Claude.ai?
2. **Use the right resource** - Docs maps for API/Code, support page for Claude.ai
3. **Verify details** - Navigate to specific documentation pages
4. **Provide answer** - Include source link and specify which product
5. **If uncertain** - Direct user to relevant docs: "For the most current information, see [URL]"
