Signal channel

signal_channel

signal_channel
mutating tool

Signal a tmux wait-for channel, waking any blocked waiters.

Returns:

str

Use when you need to wake a blocked wait_for_channel caller from a different MCP context (e.g. when a long-running task in one pane completes and another pane should proceed). Signalling an unwaited channel is a successful no-op — safe to call defensively.

Side effects: Wakes any clients blocked on the named channel. Doesn’t allocate or persist state.
