Declared compatibility
Compatibility is declared by the source manifest. End-to-end runtime verification is coming, see below.
We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.
How agent discovery & health will work →About
Cron
Use the cron tool to schedule reminders or recurring tasks that should report back to the originating chat/session when they run.
Do not use cron for periodic background checks that should stay quiet when there is nothing useful to report. For those, update HEARTBEAT.md; the protected heartbeat job runs those checks and only delivers results that pass the notification gate.
Three Modes
- Reminder - message is sent directly to user
- Task - message is a task description, agent executes and sends result
- One-time - runs once at a specific time, then auto-deletes
Examples
Fixed reminder:
cron(action="add", message="Time to take a break!", every_seconds=1200)Dynamic task (agent executes each time):
cron(action="add", message="Check HKUDS/vtx-claw GitHub stars and report", every_seconds=600)One-time scheduled task (compute ISO datetime from current time):
cron(action="add", message="Remind me about the meeting", at="")Timezone-aware cron:
cron(action="add", message="Morning standup", cron_expr="0 9 * * 1-5", tz="America/Vancouver")List/remove:
cron(action="list")
cron(action="remove", job_id="abc123")Time Expressions
| User says | Parameters | |-----------|------------| | every 20 minutes | everyseconds: 1200 | | every hour | everyseconds: 3600 | | every day at 8am | cronexpr: "0 8 " | | weekdays at 5pm | cronexpr: "0 17 1-5" | | 9am Vancouver time daily | cron_expr: "0 9 ", tz: "America/Vancouver" | | at a specific time | at: ISO datetime string (compute from current time) |
Timezone
Use tz with cron_expr to schedule in a specific IANA timezone. Without tz, the server's local timezone is used.
