-## Subagents
-
-DCP automatically skips processing for subagent sessions (`general`, `explore`, etc.), but subagents can still invoke the `prune` tool. To prevent this, disable the tool in your OpenCode config. Any custom agents you've defined should also have prune disabled:
-
-```jsonc
-// opencode.jsonc
-{
-  "agent": {
-    "general": { "tools": { "prune": false } },
-    "explore": { "tools": { "prune": false } }
-  }
