Progressive Journey
- Week 1: Foundations (install, CLAUDE.md, first agent)
- Week 2: Core Features (skills, hooks, trust calibration)
- Week 3: Advanced (MCP servers, methodologies)
- Month 2+: Production mastery (CI/CD, observability)
🔧 Rate Limits & Cost Savings
cc-copilot-bridge routes Claude Code through GitHub Copilot Pro+ for flat-rate access ($10/month instead of per-token billing).
# Install
git clone https://github.com/FlorianBruniaux/cc-copilot-bridge.git && cd cc-copilot-bridge && ./install.sh
# Use
ccc # Copilot mode (flat $10/month)
ccd # Direct Anthropic mode (per-token)
cco # Offline mode (Ollama, 100% local)
Benefits: Multi-provider switching, rate limit bypass, 99%+ cost savings on heavy usage.
🔑 Golden Rules
- Start small — First project: 10-15 lines CLAUDE.md max
- Read before edit — Always Read → Understand → Edit (never blind Write)
- Test-first — Write test → Watch fail → Implement → Pass
- Use
/compactbefore context hits 70% — prevention beats recovery - Review everything — AI code has 1.75× more logic errors (source)
- Context = Gold — Clear CLAUDE.md > clever prompts
Context management is critical. See the Cheat Sheet for thresholds and actions.

🌍 Ecosystem
Positioning: Complementary, Not Competitive
Claude Code has two major community resources:
| Resource | Focus | Best For |
|---|---|---|
| This Guide | 🎓 Educational depth, methodologies | Deep understanding, learning WHY |
| everything-claude-code | ⚙️ Production configs, plugin install | Quick setup, battle-tested patterns |
Recommended workflow: Learn concepts here → Leverage production configs there → Return for deep dives
Both resources serve different needs. Use what fits your learning style and project requirements.
Claude Cowork (Non-Developers)
Claude Cowork is the companion guide for non-technical users (knowledge workers, assistants, managers).
Same agentic capabilities as Claude Code, but through a visual interface with no coding required.
→ Claude Cowork Guide — File organization, document generation, automated workflows
Status: Research preview (Pro $20/mo or Max $100-200/mo, macOS only, VPN incompatible)
Complementary Resources
| Project | Focus | Best For |
|---|---|---|
| claude-code-templates | Distribution (200+ templates) | CLI installation (17k⭐) |
| skills.sh | Skills marketplace | One-command install (Vercel Labs) |
| awesome-claude-code | Curation | Resource discovery |
| AI Coding Agents Matrix | Technical comparison | Comparing 23+ alternatives |
Community: 🇫🇷 Dev With AI — 1500+ devs on Slack, meetups in Paris, Bordeaux, Lyon
