Diagnose current context usage and provide token optimization recommendations. Displays token usage, file count, session cost. Helps identify context-heavy operations. Use when context limits are approaching or to optimize session efficiency. 現在のコンテキスト使用状況を診断し、トークン最適化の推奨事項を提供。	Read, Glob, Grep, LS, Bash(wc:*), Bash(du:*), Bash(find:*)	inherit

/context - Context Diagnostics & Optimization

Purpose

Diagnose current context usage and provide token optimization recommendations.

Dynamic Context Analysis

Session Statistics

!`wc -l ~/.claude/CLAUDE.md ~/.claude/rules/**/*.md 2>/dev/null | tail -1`

Current Working Files

!`find . -type f -name "*.md" -o -name "*.json" -o -name "*.ts" -o -name "*.tsx" | grep -v node_modules | wc -l`

Modified Files in Session

!`git status --porcelain 2>/dev/null | wc -l`

Memory Usage Estimate

!`du -sh ~/.claude 2>/dev/null`

Context Optimization Strategies

1. File Analysis

• Large Files Detection: Identify files over 500 lines
• Redundant Files: Detect unused files
• Pattern Files: Suggest compression for repetitive patterns

2. Token Usage Breakdown

## Token Usage Analysis
- System Prompts: ~[calculated]
- User Messages: ~[calculated]
- Tool Results: ~[calculated]
- Total Context: ~[calculated]

3. Optimization Recommendations

Based on analysis, recommended optimizations:

1. File Chunking: Split large files
2. Selective Loading: Load only necessary parts
3. Context Pruning: Remove unnecessary information
4. Compression: Compress repetitive information

Usage Examples

Basic Context Check

/context
# Display current context usage

With Optimization

/context --optimize
# Detailed analysis with optimization suggestions

Token Limit Check

/context --check-limit
# Check usage against token limit

Output Format

📊 Context Diagnostic Report
━━━━━━━━━━━━━━━━━━━━━━━━━━━━
📈 Usage:
- Current Tokens: ~XXXk / 200k
- Utilization: XX%
- Estimated Remaining: ~XXXk tokens

📁 File Statistics:
- Loaded: XX files
- Total Lines: XXXX lines
- Largest File: [filename] (XXX lines)

⚠️ Warnings:
- [Warning if approaching 200k limit]
- [Warning for large files]

💡 Optimization Suggestions:
1. [Specific suggestion]
2. [Specific suggestion]

📝 Session Info:
- Start Time: [timestamp]
- Files Modified: XX
- Estimated Cost: $X.XX
━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Integration with Other Commands

• /doctor - Full system diagnostics
• /status - Status check
• /cost - Cost calculation

Best Practices

1. Regular Checks: Run periodically during large tasks
2. Warning at Limit: Alert at 180k tokens (90%)
3. Auto-optimization: Suggest automatic compression when needed

Real-time Monitoring

Track usage in real-time:

echo "Current context estimation in progress..."

Notes

• Leverages exceeds_200k_tokens flag added in Version 1.0.86
• Settings changes reflect immediately without restart (v1.0.90)
• Session statistics saved automatically via SessionEnd hook
