feat(seo): GEO optimization — llms.txt v3.32.2, llms-full.txt, FAQ

Browse source 
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.

## 🎯 What You'll Learn
## The Golden Rules
**This guide teaches you to think differently about AI-assisted development:**
- ✅ **Understand trade-offs** — When to use agents vs skills vs commands (not just how to configure them)
- ✅ **Build mental models** — How Claude Code works internally (architecture, context flow, tool orchestration)
- ✅ **Visualize concepts** — 41 Mermaid diagrams covering model selection, master loop, memory hierarchy, multi-agent patterns, security threats, AI fluency paths
- ✅ **Master methodologies** — TDD, SDD, BDD with AI collaboration (not just templates)
- ✅ **Security mindset** — Threat modeling for AI systems (only guide with 24 CVEs + 655 malicious skills database)
- ✅ **Test your knowledge** — 274-question quiz to validate understanding (no other resource offers this)
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.
**Outcome**: Go from copy-pasting configs to designing your own agentic workflows with confidence.

## 📊 When to Use This Guide vs Everything-CC
## Quick Start
Both guides serve different needs. Choose based on your priority.
| Your Goal | This Guide | everything-claude-code |
|-----------|------------|------------------------|
| **Understand why** patterns work | Deep explanations + architecture | Config-focused |
| **Quick setup** for projects | Available but not the priority | Battle-tested production configs |
| **Learn trade-offs** (agents vs skills) | Decision frameworks + comparisons | Lists patterns, no trade-off analysis |
| **Security hardening** | Only threat database (24 CVEs) | Basic patterns only |
| **Test understanding** | 274-question quiz | Not available |
| **Methodologies** (TDD/SDD/BDD) | Full workflow guides | Not covered |
| **Copy-paste ready** templates | 176 templates | 200+ templates |

**4 unique gaps no competitor covers:**
1. **Security-First** — 24 CVEs + 655 malicious skills tracked (no competitor has this depth)
2. **Methodology Workflows** — TDD/SDD/BDD comparison + step-by-step guides
3. **Comprehensive Reference** — 20K lines across 16 specialized guides (24× more reference material than everything-cc)
4. **Educational Progression** — 274-question quiz, beginner → expert path
Three commands that matter on day one: `/help` (discover features), `/init` (create CLAUDE.md), `/compact` (free context space).
**Recommended workflow:**
1. Learn concepts here (mental models, trade-offs, security)
2. Use battle-tested configs there (quick project setup)
3. Return here for deep dives (when something doesn't work or to design custom workflows)
**Both resources are complementary, not competitive.** Use what fits your current need.

## 🔑 Golden Rules
### 1. Verify Trust Before Use
Claude Code can generate 1.75x more logic errors than human-written code ([ACM 2025](https://dl.acm.org/doi/10.1145/3716848)). Every output must be verified. Use `/insights` commands and verify patterns through tests.
**Strategy:** Solo dev (verify logic + edge cases). Team (systematic peer review). Production (mandatory gating tests).
---
### 2. Never Approve MCPs from Unknown Sources
24 CVEs identified in Claude Code ecosystem. 655 malicious skills in supply chain. MCP servers can read/write your codebase.
**Strategy:** Systematic audit (5-min checklist). Community-vetted MCP Safe List. Vetting workflow documented in guide.
---
### 3. Context Pressure Changes Behavior
At 70% context, Claude starts losing precision. At 85%, hallucinations increase. At 90%+, responses become erratic.
**Strategy:** 0-50% (work freely). 50-70% (attention). 70-90% (`/compact`). 90%+ (`/clear` mandatory).
---
### 4. Start Simple, Scale Smart
Start with basic CLAUDE.md + a few commands. Test in production for 2 weeks. Add agents/skills only if need is proven.
**Strategy:** Phase 1 (basic). Phase 2 (commands + hooks if needed). Phase 3 (agents if multi-context). Phase 4 (MCP servers if truly required).
---
### 5. Methodologies Matter More with AI
TDD/SDD/BDD are not optional with Claude Code. AI accelerates bad code as much as good code.
**Strategy:** TDD (critical logic). SDD (architecture upfront). BDD (PM/dev collaboration). GSD (throwaway prototypes).

### Quick Reference
| # | Rule | Key Metric | Action |
|---|------|------------|--------|
| 1 | Verify Trust | 1.75x more logic errors | Test everything, peer review |
| 2 | Vet MCPs | 24 CVEs, 655 malicious skills | 5-min audit checklist |
| 3 | Manage Context | 70% = precision loss | `/compact` at 70%, `/clear` at 90% |
| 4 | Start Simple | 2-week test period | Phase 1→4 progressive adoption |
| 5 | Use Methodologies | AI amplifies good AND bad | TDD/SDD/BDD by context |
> Context management is critical. See the [Cheat Sheet](./guide/cheatsheet.md#context-management-critical) for thresholds and actions.

## 🤖 For AI Assistants
| Resource | Purpose | Tokens |
|----------|---------|--------|
| **[llms.txt](./machine-readable/llms.txt)** | Standard context file | ~1K |
| **[reference.yaml](./machine-readable/reference.yaml)** | Structured index with line numbers | ~2K |
**Quick load**: `curl -sL https://raw.githubusercontent.com/FlorianBruniaux/claude-code-ultimate-guide/main/machine-readable/reference.yaml`
### reference.yaml — Structure & Landing Site Search
`reference.yaml` is organized into several top-level sections:
| Section | Content |
|---------|---------|
| `lines` | Line number references for key sections in `ultimate-guide.md` |
| `deep_dive` | Key → file path mappings for all guides, examples, hooks, agents, commands |
| `decide` | Decision tree (when to use what) |
| `stats` | Counters (templates, questions, CVEs…) |
**The `deep_dive` section powers the [landing site](https://cc.bruniaux.com) CMD+K search.** The build script (`scripts/build-guide-index.mjs`) parses it to generate 160 search entries.
#### How the search index works
The CMD+K search on the landing site is an **explicit index** — not a full-text search. Only entries listed in `deep_dive` are indexed. Keywords are derived mechanically from the key name and file path, not from the file content.
**Consequence**: adding a new guide section requires explicitly adding an entry to `deep_dive`, then running `pnpm build:search` in the landing repo.
#### Maintaining reference.yaml
**Adding a new entry** to `deep_dive`:
```yaml
deep_dive:
# existing entries...
my_new_section: "guide/my-new-file.md" # local guide file
my_hook_example: "examples/hooks/bash/foo.sh" # example file
my_section_ref: "guide/ultimate-guide.md:1234" # with line number anchor
```
**Critical: avoid duplicate keys.** If a key appears twice in `deep_dive`, the YAML parser fails and the landing site search index becomes empty (0 entries). The build exits with a warning but no hard error:
```
[build-guide-index] ERROR: Failed to parse YAML: duplicated mapping key
[build-guide-index] Generating empty guide-search-entries.ts
```
Use distinct names — e.g. if you need both a line-number reference and a file path for the same concept, suffix the line-number key with `_line`:
```yaml
security_gate_hook_line: 6907 # line number ref
security_gate_hook: "examples/hooks/bash/security-gate.sh" # file path ref
```

## 📖 About
## FAQ
This guide is the result of **6 months of daily practice** with Claude Code. The goal isn't to be exhaustive (the tool evolves too fast), but to share what works in production.
**What is the Claude Code Ultimate Guide?**
The most comprehensive community guide for Claude Code (Anthropic's CLI for AI-assisted development). 22,760+ lines of documentation, 238 production-ready templates for agents, hooks, skills, and commands. Free and open-source (CC BY-SA 4.0).
**What you'll find:**
- Patterns verified in production (not theory)
- Trade-off explanations (not just "here's how to do it")
- Security first (24 CVEs tracked)
- Transparency on limitations (Claude Code isn't magic)
**How many templates are included?**
238 production-ready templates across: agents (backend-architect, security-auditor, code-reviewer), commands (/pr, /commit, /generate-tests), hooks (bash + PowerShell: secrets-scanner, dangerous-actions-blocker), and skills (pdf-generator, tdd-workflow, landing-page-generator).
**What you won't find:**
- Definitive answers (tool is too new)
- Universal configs (every project is different)
- Marketing promises (zero bullshit)
**Is this guide free?**
Yes. The guide is CC BY-SA 4.0 (share with attribution). Templates are CC0 (copy-paste freely, no attribution). No paywall, no login.
Use this guide critically. Experiment. Share what works for you.
**How is this different from the official Anthropic docs?**
The official docs explain what Claude Code does. This guide teaches you how to use it effectively in production: security hardening, custom agents, event hooks, CI/CD integration, multi-agent workflows, and real-world patterns built from 6+ months of daily practice.
