Florian BRUNIAUX 0d70fd88f0 feat(seo): GEO optimization — llms.txt v3.32.2, llms-full.txt, FAQ
Phase 1 (repo): update machine-readable/llms.txt (v3.8.0→3.32.2,
87→238 templates, 9.6K→22.7K lines), create root llms.txt per
llmstxt.org convention, create llms-full.txt (~20KB: cheatsheet,
template list, FAQ), sync mcp-server/content/llms.txt.

Phase 4 (README): replace invisible HTML keyword comment with visible
mini-FAQ (5 Q&A) for GEO crawlers.

> **6 months of daily practice** distilled into a guide that teaches you the WHY, not just the what. From core concepts to production security, you learn to design your own agentic workflows instead of copy-pasting configs.
> **If this guide helps you, [give it a star ⭐](https://github.com/FlorianBruniaux/claude-code-ultimate-guide/stargazers)** — it helps others discover it too.

## The Golden Rules
1. **Verify trust** — Claude Code can generate 1.75× more logic errors than human-written code ([ACM 2025](https://dl.acm.org/doi/10.1145/3716848)). Test everything. Use `/insights` and peer review for production paths.
2. **Vet your MCPs** — 15 vulnerabilities tracked, 655 malicious skills in supply chain. Run the 5-min audit checklist before trusting any MCP server.
3. **Manage context pressure** — At 70% context, precision drops. At 90%+, responses become erratic. Run `/compact` at 70%, `/clear` at 90%.
4. **Start simple, scale when proven** — Basic CLAUDE.md first. Add agents and skills only after 2 weeks of proven need in production.
5. **Methodologies matter more with AI** — TDD/SDD/BDD are not optional. AI accelerates bad code as fast as good code.

## Quick Start
```bash
npm install -g @anthropic-ai/claude-code
cd your-project
claude
```
Three commands that matter on day one: `/help` (discover features), `/init` (create CLAUDE.md), `/compact` (free context space).
**Personalized onboarding** (no setup needed):
```bash
claude "Fetch and follow the onboarding instructions from: https://raw.githubusercontent.com/FlorianBruniaux/claude-code-ultimate-guide/main/tools/onboarding-prompt.md"
```
**MCP Server** — use this guide from any Claude Code session without cloning:
```json
{
"mcpServers": {
"claude-code-guide": {
"type": "stdio",
"command": "npx",
"args": ["-y", "claude-code-ultimate-guide-mcp"]
}
}
}
```
→ [MCP Server README](./mcp-server/README.md) — 12 tools, 8 slash commands `/ccguide:*`, Haiku agent
