Claude Code trims repeated prompts five ways

This is a strong mental-model tutorial for Claude Code power users: the real upgrade is not a new model, but learning where each kind of context belongs.

• –CLAUDE.md and auto-memory handle durable project guidance without forcing developers to restate standards every chat
• –Skills package repeatable expertise into reusable commands, which is much cleaner than pasting giant prompt templates
• –Subagents isolate research, review, and debugging work into separate contexts so the main thread stays focused
• –Hooks turn routine guardrails and post-processing into automation, which matters for formatting, linting, and workflow hygiene
• –MCP is the big unlock for teams because it connects Claude Code to external systems like docs, tickets, chat, and internal tools
