feat(tui): Compact Mode Phase 3 - Intelligence Layer #9019

Summary

Implement Phase 3 of Compact Mode: Intelligent, context-aware compression with analytics.

Background

Phase 1-2 provide manual/threshold-based compression. Phase 3 adds intelligence for optimal compression.

Phase 3 Scope (4 weeks)

Intelligence Features

Task-Specific Compression Rules

Deliverables

• Task type detection heuristics
• Adaptive compression ratio selection
• Agent-specific shorthand dictionary system
• TMWS Memory integration for differential encoding
• Compression analytics dashboard
• ROI metrics (tokens saved, cost reduction)
• A/B testing framework for quality validation

Analytics Dashboard

┌─────────────────────────────────────────┐
│ Compact Mode Analytics                  │
├─────────────────────────────────────────┤
│ Session Tokens:     12,450 → 4,150     │
│ Compression Ratio:  3.0x               │
│ Estimated Savings:  $0.25              │
│ Quality Score:      97.2%              │
└─────────────────────────────────────────┘

Technical Notes

• LLM Understanding Impact: Adaptive (task-dependent)
• Vendor Agnostic: ✅ All techniques universal
• TMWS Integration: Uses Memory for dictionary/pattern storage

Files to Create/Modify

• packages/opencode/src/session/compression-intelligence.ts
• packages/opencode/src/session/task-detector.ts
• packages/opencode/src/cli/cmd/tui/components/analytics.tsx
• TMWS: Shorthand dictionary storage

Dependencies

• Requires: feat(tui): Compact Mode Phase 1 - Display Hierarchy Implementation #9017 (Phase 1), feat(tui): Compact Mode Phase 2 - Compression Engine Integration #9018 (Phase 2)

Success Criteria

• 75-90% token reduction achieved
• Task detection accuracy >80%
• Analytics dashboard functional
• No quality regression on sensitive tasks

ROI Projections (100K tokens/day baseline)
