Context Compaction (ACE-FCA)

Distills verbose outputs into structured summaries following ACE-FCA principles.

When to Use

Per .claude/rules/context-management.md:

•After verbose tool output (logs, JSON, search results)
•After completing a phase or milestone

Workflow

•Identify noise - What pollution sources need compacting?
•Extract signal - Correct + Complete info only
•Structure output - Use template format below

Output Template

# Compaction: {{name}}

## Trajectory
<!-- Research status → Planning status → Implementation status -->

## Key Files
<!-- files touched with purpose -->

## Completed
<!-- done items -->

## Blockers
<!-- blocking issues (empty if none) -->

## Findings
<!-- key discoveries, distilled outputs from logs/JSON/tests -->

Quality Check

•Correct > Complete > Minimal
•No raw dumps, only structured summaries
•Enough to continue, no more
•Update working plan with compaction output (don't orphan it)
