| name | golem-schedule-agent-moonbit |
| description | Scheduling a future invocation of a MoonBit Golem agent via CLI. Use when asked to schedule, delay, or set a timer for an agent method call. |
Scheduling a Future Agent Invocation
Both golem and golem-cli can be used — all commands below work with either binary.
Usage
golem agent invoke --trigger --schedule-at <DATETIME> <AGENT_ID> <FUNCTION_NAME> [ARGUMENTS...]
The --schedule-at flag schedules the invocation to execute at a specific future time. It requires the --trigger flag because scheduled invocations are always fire-and-forget — the CLI returns immediately after the invocation is enqueued.
DateTime Format
The --schedule-at value must be in ISO 8601 / RFC 3339 format with a timezone:
2026-03-15T10:30:00Z # UTC
2026-03-15T10:30:00+02:00 # With timezone offset
MoonBit-Specific Notes
- Method names use
snake_case — the same as written in the MoonBit source code
- Agent type names use
PascalCase — the struct name from the MoonBit source
Examples
Schedule a method to run at a specific time
golem agent invoke --trigger --schedule-at 2026-03-15T10:30:00Z 'MyAgent()' run_daily_report
Schedule with parameters
golem agent invoke --trigger --schedule-at 2026-04-01T00:00:00Z 'BatchProcessor("daily")' generate_report '"Q1-2026"'
Schedule in a specific environment
golem agent invoke --trigger --schedule-at 2026-03-15T08:00:00Z 'production/NotificationAgent()' send_reminders
Schedule with an idempotency key for deduplication
golem agent invoke --trigger --schedule-at 2026-03-15T10:30:00Z -i 'report-2026-03-15' 'ReportAgent()' generate_daily
Available Options
| Option | Description |
|---|
-t, --trigger | Required with --schedule-at. Fire-and-forget mode |
--schedule-at <DATETIME> | The time to execute the invocation (ISO 8601 / RFC 3339) |
-i, --idempotency-key <KEY> | Set a specific idempotency key; use "-" for auto-generated |
--no-stream | Disable live streaming of agent stdout/stderr/log |
How It Works
- The CLI sends the invocation request with the scheduled time to the Golem server
- The server enqueues the invocation to execute at the specified time
- The CLI returns immediately with the idempotency key
- At the scheduled time, the Golem runtime executes the invocation
Idempotency
Scheduled invocations use idempotency keys just like regular invocations. Providing the same idempotency key for a scheduled invocation ensures it is not executed more than once, even if the CLI command is retried.
Auto-Deploy
If the agent's component has not been deployed yet and the CLI is run from an application directory, the command will automatically build and deploy the component before scheduling.
Value Syntax
The agent ID parameters and method arguments use Rust syntax:
- Field names use
snake_case
- Options:
Some(value) / None
- Records:
MyRecord { field_one: 1, field_two: "hello" }
- Enums/Variants:
MyEnum::VariantName(value)
- Tuples:
(1, "hello")
golem agent invoke --trigger --schedule-at 2026-03-15T10:30:00Z 'MyAgent("user-123")' run_task 'TaskConfig { priority: 1, retry: true }'
