Heartbeat

Heartbeat & Reminder Scheduler

Use this skill when the user wants to schedule recurring agent tasks, automated check-ins, or simple reminders.

1. Choosing the Right Mechanism

When the user asks to schedule something, choose the appropriate system:

• HEARTBEAT.md (Workspace-Scoped, Permanent): Use this for structured, workspace-bound recurring agent prompts (e.g., weekly project summaries, morning inbox triage, or build-status checks). These are checked into Git, shared with other team members/agents in the workspace, and support global text guidelines.
• Database Reminders (Personal, Transient): Use this for personal, lightweight, or one-shot conversational reminders (e.g., "remind me to check X in 2 hours" or "remind me about Y tomorrow"). This is done purely through the reminder_schedule tool, bypassing files and manual syncing.

2. Modifying the Heartbeat (HEARTBEAT.md)

When updating workspace-scoped heartbeat checks:

Step 1: Read the Existing Config

Open and inspect HEARTBEAT.md at the workspace root to check for existing cron checks.

• If the file does not exist, initialize it with a markdown title and the YAML front-matter fences.

Step 2: Formulate the Cron Check

Construct the cron check dictionary with the following schema keys:

• name: Unique, lowercase, and strictly no whitespace (e.g., morning_pulse).
• cron: A valid 5-field cron trigger string (validated at parse time).
• prompt: The self-contained instruction/prompt for the agent when it fires.

Step 3: Write to File

• Write or update the check in the YAML front matter of HEARTBEAT.md.
• Preserve all pre-existing checks.
• Optional: If the user provides general guidance on how checks should behave (e.g., "ignore emails from automated senders"), append it to the markdown body below the front matter so the agent reads it contextually when any check executes.

Step 4: Instruct the User to Sync

The agent does not have direct sync tool permissions. Once the file is updated, tell the user:

"I've successfully updated HEARTBEAT.md with your new schedule. Please click the Sync button in the Settings UI (or send a POST to /api/v1/heartbeat/sync) to activate the new schedules in the job database."

3. Scheduling Database Reminders

When the user wants simple reminders (one-shot or chat-only recurring tasks):

1. Use reminder_list to check if a similar schedule already exists.
2. Invoke reminder_schedule with a descriptive name, prompt, and either cron_expression or fire_at.
3. Inform the user of success and print the registered Job UUID.
