AC Context Compactor
Manage context usage and create compact summaries for session continuation.
Purpose
Monitors context usage and creates compact summaries when approaching limits, enabling seamless session continuation without losing critical information.
Quick Start
from scripts.context_compactor import ContextCompactor
compactor = ContextCompactor(project_dir)
if await compactor.should_compact():
summary = await compactor.create_compact_summary()
Context Management
Context threshold: 85%
│
├── Below 85%: Continue normally
├── At 85%: Create compact summary
└── Above 90%: Force handoff
Compaction Strategy
- Preserve: Critical state and progress
- Summarize: Completed features
- Extract: Key decisions and context
- Compress: Verbose information
