Important Claude Code Features You have to know. 1. CLAUDE.md (Project Memory) Think of this as your project brain. Define coding standards, architecture decisions, naming conventions, or even “how to think” about your repo. Claude reads it at the start of every session → giving you consistent, context-aware outputs. 2. Permissions Full control over what Claude can access. Limit tools, file edits, or commands to avoid risky operations and enforce safe automation. 3. Plan Mode Claude thinks before acting. It generates a step-by-step plan that you can review before any code changes happen—perfect for complex refactors or critical systems. 4. Checkpoints Automatic snapshots of your codebase. Break something? No stress—just roll back instantly. This makes experimentation much safer and faster. 5. Skills Reusable instruction modules. Instead of repeating prompts, create skill files that Claude automatically follows—great for testing patterns, formatting, or workflows. 6. Hooks Run custom scripts at key lifecycle moments like: PreToolUse PostToolUse This enables automation like: ✔ Running tests after edits ✔ Formatting code automatically ✔ Triggering CI workflows 7. MCP (Model Context Protocol) A game changer. Connect Claude to: Databases APIs Internal tools Now Claude isn’t just generating code—it’s interacting with real systems. 8. Plugins Extend functionality with third-party integrations. Plugins bundle: Skills MCP connections Hooks Think of it as an ecosystem for Claude-powered development. 9. Context Management (/context) Control what Claude sees. You can: Add/remove files Manage token usage Focus attention on relevant parts This improves both accuracy and performance. 10. Slash Commands Create shortcuts for repetitive workflows. Type / and trigger predefined actions like: Code reviews Test generation Refactoring Huge productivity boost. 11. Compaction Long chat? No problem. Claude compresses conversations while preserving meaning—saving tokens without losing context. 12. Subagents Parallel execution Spawn multiple agents to handle different parts of a task simultaneously. Perfect for: Large refactors Multi-file updates Complex pipelines 13. Streaming Edits See changes happen in real time instead of waiting—great for faster feedback loops. 14. Inline Diff View Understand exactly what changed in your code with clear diffs—ideal for reviews. 15. Test Awareness Claude can generate, update, and reason about tests alongside your code—helping maintain high reliability. 16. Multi-File Reasoning It doesn’t just look at one file—it understands relationships across your entire codebase. ❔ Which of these features are you already using? And which one surprised you the most?
