The handle every plugin programs against:
- `agent.send(content, options?)` — the one delivery primitive over the (`target` × `wakeup`) matrix; `Agent` is an abstract class whose `followup`/`steer`/`inject` aliases are fixed-preset delegates to it. It returns the accepted message's opaque `AgentMessageId`, which the message's `agent/inbox/enqueue`/`dequeue`/`discard` events carry so a caller can correlate a queued item with its lifecycle. Omitting the whole options object selects `{ target: 'next-turn', wakeup: true, source: { kind: 'user' } }`; a supplied `SendOptions` must provide all three fields. `target: 'next-turn'` queues one independent FIFO item that, if admitted, becomes the sole ordinary prompt in its turn. `target: 'next-step'` with `wakeup: true` submits steering, while `target: 'next-step'` with `wakeup: false` injects durable context without running the model. The [one-send-one-turn Agent Note](../../../.agents/notes/implemented/simplification/2026-07-17-one-send-one-turn.md) owns the turn rationale.
- `agent.send(content, options)` — the one delivery primitive over the (`target` × `wakeup`) matrix; `Agent` is an abstract class whose `followup`/`steer`/`inject` aliases are fixed-preset delegates to it. It returns the accepted message's opaque `AgentMessageId`, which the message's `agent/inbox/enqueue`/`dequeue`/`discard` events carry so a caller can correlate a queued item with its lifecycle. `SendOptions` requires `target`, `wakeup`, and `source`; callers wanting the ordinary user-message preset use `followup(content)`. `target: 'next-turn'` queues one independent FIFO item that, if admitted, becomes the sole ordinary prompt in its turn. `target: 'next-step'` with `wakeup: true` submits steering, while `target: 'next-step'` with `wakeup: false` injects durable context without running the model.

- `agent.followup(content, options?)` — the `next-turn`/wakeup preset of `send()`: queue an ordinary follow-up turn and wake the driver.
- `agent.steer(content, options?)` — the `next-step`/wakeup preset: while a turn is open, stage steering for its next safe boundary without dispatching `agent/prompt-submit`; when idle, delegate to a woken follow-up. Cancellation or disposal may discard pending steering.
- `agent.inject(content, options?)` — the `next-step`/no-wakeup preset: append model-facing context without running the model; the next request sees a verbatim user-role message whose provenance is carried by `source`. While a turn is open, injection waits in the outbox for the next safe boundary. While idle, it appends immediately without opening a turn; persistence reacts to `session/event` independently. Injection emits no `agent/inbox/*` event.
