The Context Compression feature optimizes token usage in conversations with Claude Code, enabling longer conversations and processing of more information. Through 3 compression modes, you can select the optimal compression strategy suited to your project characteristics and work requirements.
- Claude Code has per-conversation token limits
- Context overflow frequent when working with large codebases
- Possible information loss in long conversation sessions
- Average token usage reduction of 50% or more
- Simultaneous processing of more files and information
- Improved conversation continuity
- Increased cost efficiency
Compression Rate: 70-80%
Quality Loss: Medium-High
Processing Speed: Fast
Characteristics:
- Maximum token savings
- Retains only core information
- Some loss of details and context
- Uses short and concise expressions
Compression Strategy:
- Remove comments and documentation
- Summarize repetitive code patterns
- Shorten variable names
- Minimize whitespace and formatting
- Remove duplicate information
Suitable Situations:
- Exploring very large codebases
- When general understanding is needed
- Fast prototyping
- When token budget is very limited
Usage Example:
/project:aiwf:compress_context:aggressive
# or
/프로젝트:aiwf:컨텍스트_압축:공격적Compression Rate: 50-60%
Quality Loss: Low
Processing Speed: Medium
Characteristics:
- Balance between compression rate and quality
- Preserves important information
- Maintains readability
- Ensures structural integrity
Compression Strategy:
- Clean up duplicate comments
- Summarize long descriptions
- Remove unused code
- Smart whitespace management
- Context-based compression
Suitable Situations:
- General development tasks
- Code review and analysis
- Bug fixing tasks
- Feature implementation and modification
Usage Example:
/project:aiwf:compress_context:balanced
# or
/프로젝트:aiwf:컨텍스트_압축:균형Compression Rate: 30-40%
Quality Loss: Very Low
Processing Speed: Slow
Characteristics:
- Minimal information loss
- Preserves all important details
- High similarity to original
- Enables precise work
Compression Strategy:
- Remove only obvious duplicates
- Maintain formatting
- Preserve comments and documentation
- Keep meaningful whitespace
- Apply only safe compression
Suitable Situations:
- Precise debugging
- Security audits
- Performance optimization
- Working with critical production code
Usage Example:
/project:aiwf:compress_context:conservative
# or
/프로젝트:aiwf:컨텍스트_압축:보수적What's the nature of the task?
├─ Exploration/Overview → Aggressive
├─ General development → Balanced
└─ Precise/Critical work → Conservative
Token budget?
├─ Very limited → Aggressive
├─ Normal → Balanced
└─ Abundant → Conservative
Required information level?
├─ Overview only → Aggressive
├─ Main logic → Balanced
└─ All details → Conservative
| Task Type | Recommended Mode | Reason |
|---|---|---|
| Architecture Review | Aggressive | Overall structure understanding important |
| Bug Fixing | Balanced | Need balance of context and details |
| Performance Optimization | Conservative | All details important |
| Code Refactoring | Balanced | Need to maintain structure while improving |
| Security Audit | Conservative | Can't miss any details |
| Documentation Generation | Aggressive | Only core functionality needed |
| Test Writing | Balanced | Need to understand main logic |
/project:aiwf:compress_context[:<mode>]Compress entire project with Aggressive mode:
/project:aiwf:compress_context:aggressive
"Please compress and show all JavaScript files in the src folder"Compress specific module with Balanced mode:
/project:aiwf:compress_context:balanced
"Please compress and analyze the main logic of the authentication module"Compress important file with Conservative mode:
/project:aiwf:compress_context:conservative
"Please compress payment.js file minimally and review for security vulnerabilities"1. Selective Compression Compress only specific files or directories:
/project:aiwf:compress_context:balanced
"Please compress only the src/api folder and exclude the tests folder"2. Multi-stage Compression Compress large projects in stages:
# Stage 1: Understand overall structure
/project:aiwf:compress_context:aggressive
"Please show the overall project structure"
# Stage 2: Detailed analysis of areas of interest
/project:aiwf:compress_context:balanced
"Please analyze authentication-related modules in more detail"3. Compression Exclusion Settings Exclude important parts from compression:
/project:aiwf:compress_context:aggressive
"Please compress everything but don't compress security.js"Compression Rate = (Original Tokens - Compressed Tokens) / Original Tokens × 100
Information Preservation Rate:
- Aggressive: 60-70%
- Balanced: 85-90%
- Conservative: 95-98%
Structural Integrity:
- Aggressive: Basic structure only
- Balanced: Maintains overall structure
- Conservative: Complete preservation
Readability Score:
- Aggressive: Low (machine-friendly)
- Balanced: Medium (developer-friendly)
- Conservative: High (similar to original)
- Aggressive: Fastest (simple rule application)
- Balanced: Medium (includes context analysis)
- Conservative: Slow (requires detailed analysis)
- All modes: 1.5-2x original size memory required
- Large files processed in chunks
- Cache utilization when recompressing same files
- Cache validity period: 15 minutes
- Automatic refresh when files change
Symptoms: Important information is missing Solutions:
- Change to more conservative mode
- Exclude important parts from compression
- Use selective compression
Symptoms: Token savings don't meet expectations Solutions:
- Try more aggressive mode
- Exclude unnecessary files
- Manual cleanup before compression
Symptoms: Errors occur during compression Solutions:
- Check file encoding
- Review special characters or formats
- Compress in smaller units
- First understand the nature of the task
- Pre-select appropriate mode
- Change mid-way if necessary
- Use staged approach for large projects
- Start with Aggressive to understand overall
- Detailed analysis of needed parts with Balanced/Conservative
- Exclude important configuration files
- Exclude security-related code
- Exclude complex algorithms
# Example: Hybrid approach
1. Overall structure: Aggressive
2. Core modules: Balanced
3. Problem areas: Conservative- Smart Auto Mode: AI determines task nature and automatically selects
- Custom Compression Rules: Project-specific compression settings
- Compression Presets: Save frequently used settings
- Real-time Compression Preview: Preview compression results beforehand
- 30% improvement in compression speed
- 20% reduction in memory usage
- Additional 10% improvement in compression rate
The Context Compression feature is an essential tool for efficient collaboration with Claude Code. By understanding the characteristics of each mode and selecting the appropriate mode for your tasks, you can develop smoothly even in large projects without token limitations.
We encourage you to develop compression strategies optimized for your projects through continuous use.
