 ## How Pruning Works
 
-DCP uses multiple tools and strategies to reduce context size:
+DCP uses one user-facing tool and strategies to reduce context size:
 
-### Tools
+For model-facing behavior (prompts and tool calls), this capability is always addressed as `compress`.
 
-**Distill** — Exposes a `distill` tool that the AI can call to distill valuable context into concise summaries before removing the tool content.
+### Tool
 
-**Compress** — Exposes a `compress` tool that the AI can call to collapse a large section of conversation (messages and tools) into a single summary.
+**Compress** — Exposes a single `compress` tool with one method: select a conversation range using injected `startId` and `endId` (`mNNNN` or `bN`), then replace it with a technical summary.
 
-**Prune** — Exposes a `prune` tool that the AI can call to remove completed or noisy tool content from context.
+The model can use that same method at different scales: tiny ranges for noise cleanup, focused ranges for preserving key findings, and full chapters for completed work.
