Struct RunOptions 

pub struct RunOptions {
    pub no_execute: bool,
    pub task_id: Option<String>,
    pub cancel: Option<CancellationToken>,
    pub deadline: Option<Duration>,
    pub stream_ndjson: bool,
    pub seed: Option<ConversationHistory>,
    pub output_schema: Option<Value>,
    pub event_tx: Option<Sender<RunEvent>>,
    pub plan: bool,
    pub plan_autoaccept: bool,
}

Per-invocation options for run_non_interactive.

Added as a struct so new flags can land without reshuffling the function’s positional args. All fields default to “no change”.

Fields

no_execute: bool

When true, register an empty ToolRegistry — the model sees no tools and can’t take actions. Dry-run mode for mermaid run --no-execute.

task_id: Option<String>

Durable runtime task that owns this run, when launched through mermaidd or mermaid run task creation.

cancel: Option<CancellationToken>

External cancellation. When it fires, the driver injects Msg::CancelTurn — the same message the TUI’s Esc sends — so the reducer unwinds the turn gracefully (tool process tree killed, turn JoinSet drained). If the reducer hasn’t reached Idle within a grace window after that, the drive loop hard-stops.

deadline: Option<Duration>

Wall-clock budget override. None keeps the built-in 20-minute deadline.

stream_ndjson: bool

When true, the driver streams the run lifecycle to stdout as newline-delimited RunEvent JSON (mermaid run --format ndjson). Off for the daemon scheduler and every other caller, which own their own output.

seed: Option<ConversationHistory>

Saved conversation to seed the session with (--resume <id> / --continue). The run appends to the SAME session id, so repeated --resume <id> invocations chain naturally.

output_schema: Option<Value>

--output-schema: JSON Schema the final answer must conform to. The agentic loop runs normally; one extra FORMATTING turn (no tools, native constrained output where supported) reshapes the final answer, validated client-side. See run_formatting_turn.

event_tx: Option<Sender<RunEvent>>

Live RunEvent tee for daemon task subscriptions (subscribe_task). Every event that would print on an NDJSON stream is also broadcast here (send is sync + non-blocking; no-receiver errors are ignored).

plan: bool

mermaid run --plan: enter plan mode before the prompt seeds, so the run explores read-only and delivers a plan file.

plan_autoaccept: bool

--plan-autoaccept: the headless approval starts implementation immediately instead of ending the run at the plan.
