+# Typing indicators
+
+Typing indicators are sent to the chat channel while a run is active. Use
+`agents.defaults.typingMode` to control **when** typing starts and `typingIntervalSeconds`
+to control **how often** it refreshes.
+
+## Defaults
+
+When `agents.defaults.typingMode` is **unset**, OpenClaw keeps the legacy behavior:
+
+- **Direct chats**: typing starts immediately once the model loop begins.
+- **Group chats with a mention**: typing starts immediately.
+- **Group chats without a mention**: typing starts only when message text begins streaming.
+- **Heartbeat runs**: typing is disabled.
+
+## Modes
+
+Set `agents.defaults.typingMode` to one of:
+
+- `never` — no typing indicator, ever.
+- `instant` — start typing **as soon as the model loop begins**, even if the run
+  later returns only the silent reply token.
+- `thinking` — start typing on the **first reasoning delta** (requires
+  `reasoningLevel: "stream"` for the run).
+- `message` — start typing on the **first non-silent text delta** (ignores
+  the `NO_REPLY` silent token).
+
+Order of “how early it fires”:
+`never` → `message` → `thinking` → `instant`
+
+## Configuration
+
+```json5
+{
+  agent: {
+    typingMode: "thinking",
+    typingIntervalSeconds: 6,
+  },
+}
+```
+
+You can override mode or cadence per session:
+
+```json5
+{
+  session: {
+    typingMode: "message",
+    typingIntervalSeconds: 4,
+  },
+}
+```
+
+## Notes
+
+- `message` mode won’t show typing for silent-only replies when the whole
+  payload is the exact silent token (for example `NO_REPLY` / `no_reply`,
+  matched case-insensitively).
+- `thinking` only fires if the run streams reasoning (`reasoningLevel: "stream"`).
+  If the model doesn’t emit reasoning deltas, typing won’t start.
+- Heartbeats never show typing, regardless of mode.
+- `typingIntervalSeconds` controls the **refresh cadence**, not the start time.
+  The default is 6 seconds.
