+# Compaction
+
+OpenClaw's compaction feature manages context window limitations by summarizing older conversation history while preserving recent messages.
+
+## What Compaction Does
+
+Compaction summarizes older conversation into a compact summary entry and keeps recent messages intact. The summaries remain stored in session history for future reference.
+
+## Two Compaction Types
+
+### Auto-compaction
+
+Triggers automatically when sessions approach or exceed the model's context limits. Users see a "Auto-compaction complete" notification in verbose mode.
+
+### Manual compaction
+
+Initiated via the `/compact` command, optionally with custom instructions like "Focus on decisions and open questions."
+
+## Compaction vs Session Pruning
+
+| Feature | Compaction | Session Pruning |
+|---------|------------|-----------------|
+| Action | Summarizes and persists in JSONL | Trims old tool results only |
+| Scope | Full conversation history | In-memory, per request |
+| Persistence | Permanent | Temporary |
+
+## Practical Guidance
+
+- Use `/compact` when sessions feel outdated or context becomes bloated
+- Use `/new` or `/reset` when starting fresh sessions is preferred
