Objective

Implement context compaction that frees memory when agents reach 80% context usage.

Implementation Details

Build compaction from Part 1:

Compaction process:

  • Detect 80% context threshold
  • Request summary from agent (completed work, patterns, decisions)
  • Replace conversation history with concise summary
  • Validate context reduction achieved

Goal: Free 40-50% of context through summarization.

Context Estimate

  • Files to modify: 1 (context_monitor.py)
  • Implementation complexity: medium (20,000 tokens)
  • Test requirements: medium (10,000 tokens)
  • Documentation: medium (3,000 tokens)
  • Total estimated: 46,800 tokens
  • Recommended agent: glm

Difficulty

medium

Dependencies

  • Blocked by: #157 (COORD-010)
  • Blocks: #159 (COORD-012)

Acceptance Criteria

  • Compaction triggered at 80% context threshold
  • Summary prompt generates concise work summary
  • Conversation history replaced with summary
  • Context reduction measured (target: 40-50%)
  • Compaction logged with before/after metrics
  • Unit tests (85% coverage minimum)

Testing Requirements

  • Mock agent context at 80% threshold
  • Test summary generation
  • Test conversation replacement
  • Measure context reduction effectiveness
  • Test compaction failure handling
  • Coverage: 85% minimum
