+# Tool Display Configuration
+
+Control how tool calls are rendered in chat messages during agent responses.
+
+## Configuration
+
+```toml
+[reactions]
+tool_display = "compact"   # full | compact | none
+```
+
+### Helm
+
+```yaml
+agents:
+  kiro:
+    reactions:
+      toolDisplay: "compact"   # full | compact | none
+```
+
+## Modes
+
+### `compact` (default)
+
+Shows a single-line count summary. No tool names, commands, or arguments are displayed.
+
+```
+✅ 3 · 🔧 1 tool(s)
+
+Agent response text here...
+```
+
+Best for: everyday use, public channels, mobile.
+
+### `full`
+
+Shows each tool call with its complete title. When more than 3 tools finish, they collapse into a count summary automatically.
+
+```
+✅ `curl -s "https://ghcr.io/v2/openabdev/charts/openab/tags/list"`
+✅ `grep -r "pattern" src/`
+🔧 `npm install`...
+
+Agent response text here...
+```
+
+Best for: debugging, understanding what the agent is doing step by step.
+
+### `none`
+
+Hides tool lines entirely. Only the final agent response is shown. Reaction emojis (🔧→✅) still work, so you can tell the agent is busy.
+
+```
+Agent response text here...
+```
+
+Best for: clean output when you only care about the final answer.
+
+## Icons
+
+| Icon | Meaning |
+|------|---------|
+| 🔧 | Tool is running |
+| ✅ | Tool completed successfully |
+| ❌ | Tool failed |
+
+## Notes
+
+- **Default changed**: `compact` is the new default. Previously, tool calls were always shown in full. If you want the old behavior, set `tool_display = "full"`.
+- **Reaction emojis are independent**: The emoji reactions on messages (👀→🤔→🔧→🆗) work regardless of `tool_display` setting.
+- **Streaming behavior**: In `compact` mode, the count updates in real-time as tools start and finish. In `full` mode, individual tool lines appear and update during streaming.
