This is a capability probe. Do not do any file work.
- Call ListAgents and report the EXACT full output verbatim.
- Report whether a tool named SendMessage is available to you. If its schema is not loaded, try ToolSearch with query "select:SendMessage" and report whether that succeeds and what the schema says.
- If SendMessage is available, try to send a message to an agent named "probe-b" and report the exact error or success text.
Your final message: the verbatim ListAgents output, whether SendMessage exists for you, and the exact result of the send attempt. Be literal and complete — quote tool outputs exactly, do not summarise.

ListAgents does not appear to exist as a tool in this environment — ToolSearch cannot find it under any query I tried ("select:ListAgents", "list agents teammates"), and it is not among the deferred tools listed in the system reminders (EnterWorktree, ExitWorktree, Monitor, NotebookEdit, SendMessage, TaskStop, WebFetch, WebSearch, plus the Gmail/Calendar/Drive MCP tools). So I cannot report verbatim ListAgents output — the tool is unavailable to me, not merely unloaded.
Now attempting the SendMessage call to "probe-b" as requested.

Report:
1. ListAgents: Not available. I attempted ToolSearch with query "select:ListAgents" (result: No matching deferred tools found) and with query "list agents teammates" (returned only SendMessage, EnterWorktree, and WebSearch — no ListAgents). No tool named ListAgents is listed in the deferred-tools system reminders either. I have no verbatim output to give because the tool does not exist in my toolset.
2. SendMessage: Available. It was not initially loaded (only listed by name in the deferred-tools reminder), but ToolSearch with query "select:SendMessage" succeeded and loaded its full schema. Schema summary: takes to (recipient — teammate name, "main", or an agent from ListAgents, optionally with a [ref] suffix), message (plain text content), optional summary (5-10 word UI preview), and optional notify_when_idle (boolean, one-shot idle notification subscription).
3. Send attempt to "probe-b": Called SendMessage with to: "probe-b", message: "probe". Exact result:
{"success":false,"message":"No agent named 'probe-b' is reachable.\nCheck the spelling, or use the agent ID from a background agent's spawn result."}
