Apus runs work in the background through native runtimes, scheduled jobs, event hooks, and standing instructions. Use this page to pick the right mechanism.

| Use case | Recommended | Why |
|---|---|---|
| Send daily report at 9 AM sharp | Automations | Exact timing, isolated execution |
| Remind me in 20 minutes | Automations | One-shot with precise timing (--at) |
| Run weekly deep analysis | Automations | Standalone task, can use different model |
| Check inbox every 30 min | Automations | Independent recurring schedule and job history |
| Trigger safely on new IMAP email | IMAP plugin | Sender-gated isolated reader sessions |
| Monitor calendar for upcoming events | Automations | Explicit recurring schedule and delivery policy |
| Surface ambient main-session updates | Heartbeat | System-owned monitor automation and quiet alerts |
| Run a script on session reset | Hooks | Internal HOOK.md scripts react to lifecycle events |
| Trigger an agent from an external service | Webhooks | Authenticated HTTP ingress, not an internal event hook |
| Execute code on every tool call | Plugin hooks | Typed api.on(...) handlers can intercept tool calls |
| Always check compliance before replying | Standing Orders | Injected into every session automatically |
Automations vs Heartbeat
| Dimension | User-authored automations | Heartbeat monitor automation |
|---|---|---|
| Timing | One-shot, interval, or cron expression | Scheduler-owned interval, default 30min |
| Session context | Isolated, current, named, or main session | Main session, optionally isolated |
| Delivery | Channel, webhook, or silent | Owner-routed alerts or silent |
| Best for | Explicit reports, reminders, recurring work | Ambient monitoring and event follow-up |
Both use the same Automations scheduler. Create an automation for work with its own instructions or schedule; use heartbeat as the system-owned ambient monitor when periodic main-session awareness is useful.
Core concepts
Automations
Automations are Apus's built-in scheduler for all recurring and one-shot work, including heartbeat monitors. The scheduler persists jobs, wakes the agent at the right time, and can deliver output to a chat channel or webhook endpoint. It supports one-shot reminders, recurring intervals and cron expressions, and inbound webhook triggers.
See Automations.
Background execution and workflows
Use Sub-agents to launch and wait for delegated runs, ACP for coding harness sessions, and automation run history to inspect scheduled work. Each runtime owns execution and completion.
Lobster runs local pipelines with resumable approvals. The shared Tasks ledger, TaskFlow orchestration API, and TaskFlow Webhooks plugin have been removed. Generic Gateway HTTP hooks remain available for authenticated external triggers.
Standing orders
Standing orders grant the agent permanent operating authority for defined programs. They live in workspace files (typically AGENTS.md) and are injected into every session. Combine with automations for time-based enforcement.
See Standing Orders.
Hooks
Internal hooks are event-driven scripts triggered by agent lifecycle events
(/new, /reset, /stop), session compaction, gateway startup, and message
flow. They are discovered from hook directories and managed with
apus hooks. For in-process tool-call interception, use
Plugin hooks.
See Hooks.
Heartbeat
Heartbeat is a system-owned monitor automation that runs a periodic main-session
turn, every 30 minutes by default. It can use small monitor-scratch context to
surface anything requiring attention without extending session freshness. Create separate automation jobs for work requiring
its own schedule. Empty scratch skips as empty-heartbeat-file. Scheduled
monitor turns defer while the main queue or automation work is busy, another run
for the same agent is active, or the target session has active or queued work.
See Heartbeat.
How they work together
- Automations own every recurring schedule, including reports, reminders, and heartbeat monitors.
- Heartbeat is the system-owned ambient monitor automation. Independently scheduled checks belong in their own automation jobs.
- Hooks react to specific events (session resets, compaction, message flow) with custom scripts. Plugin hooks cover tool calls.
- Standing orders give the agent persistent context and authority boundaries.
Retired inferred commitments
The inferred commitments experiment was removed in v2026.8.1: Apus no longer
extracts follow-ups from conversations or delivers them through heartbeat.
The apus commitments maintenance CLI is also gone. The database migration
discards the old commitment rows and removes their table and indexes.
For reminders or scheduled work, create an explicit automation. Automations are an alternative with a schedule and instructions you choose; they do not restore inferred follow-ups.
