1. Understand the Context Window Limits
Claude Code has a context window that limits how much information can be processed in a single conversation. Understanding this is key to working efficiently.
- Context window includes all previous messages in the conversation
- Large files and lengthy outputs consume significant tokens
- When context gets full, older messages are compressed to make room
- Monitor your conversation length for performance
💡 Pro Tip: Start fresh conversations when tackling new projects to have a full context window for that specific task.
2. Use Session Memory Effectively
Claude Code can save information across conversations for easier recall:
- Store project summaries in session memory for context
- Save important decisions and architecture notes
- Document naming conventions and project patterns
- Keep track of important URLs, IDs, and credentials (securely)
3. Prune Old Conversations
Regular maintenance keeps your memory clean and efficient:
- Delete completed conversations that you won't need again
- Archive important learnings in documentation
- Keep working conversations focused on current tasks
- Use descriptive conversation titles for easy retrieval
4. Break Up Large Tasks Into Smaller Conversations
Instead of trying to do everything in one conversation:
- Phase 1: Plan and design (separate conversation)
- Phase 2: Core implementation (separate conversation)
- Phase 3: Testing and refinement (separate conversation)
- Phase 4: Documentation and deployment (separate conversation)
5. Use Agents for Memory-Heavy Tasks
Agents have their own context separate from your main conversation:
- Launch agents for code exploration and research
- Agents can read large files without filling your context
- Perfect for understanding complex codebases
- Results are summarized back to you efficiently
6. Reference Files Instead of Pasting Them
When working with code, reference files strategically:
- Paste specific functions, not entire files
- Use
Ctrl+G(Mac:⌃G) to edit in external editor for large prompts - Reference file paths instead of full content when possible
- Ask Claude Code to read files directly from your project
7. Implement Memory Saving Hooks
Use Claude Code's hook system to save important information automatically:
- Create hooks that save key decisions to memory
- Auto-save architecture diagrams or design docs
- Log important patterns discovered during development
- Capture and store solutions to common problems
8. Use Plan Mode Strategically
Plan mode helps you save tokens on certain tasks:
- Launch plan mode to get structured approach before implementation
- Read the plan without executing to save context
- Ask targeted follow-up questions about specific aspects
- Implement based on the plan with fresh context
9. Summarize and Archive Completed Work
At the end of each conversation, create a summary:
- Document what was accomplished
- Save key decisions and trade-offs made
- Note any outstanding issues or follow-ups
- Store for reference in future conversations
10. Manage Memory for Long-Running Projects
For multi-week or multi-month projects:
- Maintain a "project bible" document with overview and key info
- Create weekly summaries of progress and decisions
- Reference the summary at the start of new sessions
- Keep technical decisions documented in code comments
