Problem

t3 thread send always sends with mode: "queue" (apps/server/src/cli/thread.ts). A script that sends to a busy thread cannot reach the agent until its whole turn ends. In my case, a small service forwards review notes from a web page to the agent's thread, and a note waits behind a long build.

A script cannot work around this by calling /mcp itself: a token from t3 auth session issue --subject mcp-client has the approval-required runtime ceiling, so t3_thread_send rejects a full-access thread. The CLI's own MCP session has the full-access ceiling.

Change

t3 thread send takes --mode queue|auto|steer|restart and passes it to t3_thread_send. The default stays queue, so current scripts behave the same. The text output names the delivery (Queued., Steered., Restarted., Sent.) instead of "Sent." for all but a queue. docs/user/outside-agents.md describes the flag.

Scope and approval

This is a focused option for an established capability. t3_thread_send already offers auto, queue, steer and restart to agents through MCP, and the app steers follow-ups by default. The flag exposes the same modes to the CLI that already calls this tool. It adds no new server behavior, and the default does not change.

Verification

• vp run check:changed: format, lint, knip, typecheck and the thread CLI tests pass.
• node apps/server/src/bin.ts thread send --help lists --mode choice ... (choices: queue, auto, steer, restart), default queue.
• Against a running Nightly server (0.1.3-nightly.20261027.3754): I applied the same one-line change to the shipped CLI bundle and sent a note with mode auto to a thread whose turn was running sleep 75. The result was "delivery":"steered", and the note appeared inside that running turn, before the agent's reply. A send without the flag still prints Queued. for a busy thread.
• Not checked: --mode restart against a live thread, and the source CLI against a live server, because AGENTS.md says not to write to the live T3 home from a dev checkout.

Approvability

Verdict: Approved at cbeabf1

Macroscope's review found this PR approvable — Adds an opt-in --mode flag to expose existing queue, auto, steer, and restart delivery modes; the default remains queue, so existing CLI behavior is unchanged. The implementation is a small CLI pass-through plus documentation, with no new server-side orchestration or schema changes.

Walkthrough

thread send now accepts queue, auto, steer, and restart modes. It passes the selected mode to t3_thread_send and displays a label for the delivery result. The documentation describes the modes.

Changes: Thread send delivery modes

Layer / File(s)	Summary
Configure and report delivery modes apps/server/src/cli/thread.ts, docs/user/outside-agents.md	The command adds the four delivery modes, defaults to queue, passes the selected mode to t3_thread_send, and maps delivery results to distinct labels. The documentation describes the mode behavior.

Describe the idle behavior for auto.

The server contract starts an idle thread, steers a running turn, or queues when appropriate. This help text says auto “otherwise queues,” which is misleading. Update it to match the server behavior.
