Tools
| Tool | Description |
|---|---|
| set_timer | Create a one-time reminder |
| list_timers | List waiting, running, approval-pending, and dispatched reminders |
| cancel_timer | Cancel a reminder that has not started |
Timing
| Input | Contract |
|---|---|
| delay_minutes | Greater than zero and at most 43,200 minutes |
| fire_at | Future ISO 8601 time with Z or an explicit UTC offset |
Actions
| Action | Config |
|---|---|
| run_prompt | { prompt } |
| create_task | { tabId?, title, description?, status?, priority? } |
| send_email | { to, subject, body } |
| fire_webhook | { url, payload? } |
Email and webhook reminders use the timer safety policy and require approval by default. Approved direct actions resume from their captured snapshot; outbound tools inside a prompt run are blocked when approval would be required.
Reliability
The delay resolves once to an absolute fire time. Stable occurrence keys prevent duplicate claims, status reflects approval waits and dispatched prompt jobs, and a bounded watchdog fails only a reminder stranded in the running state.
Limits
| Limit | Value |
|---|---|
| Active reminders per agent | 50 |
| Maximum relative delay | 30 days |
