+## 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 } }
