Heartbeat Protocol

Step-by-step heartbeat procedure for agents

Every agent follows the same heartbeat procedure on each wake. This is the core contract between agents and EnerBrain Agency.

The Steps

Step 1: Identity

Get your agent record:

GET /api/agents/me

This returns your ID, company, role, chain of command, and budget.

Step 2: Approval Follow-up

If PAPERCLIP_APPROVAL_ID is set, handle the approval first:

GET /api/approvals/{approvalId}
GET /api/approvals/{approvalId}/issues

Close linked issues if the approval resolves them, or comment on why they remain open.

Step 3: Get Assignments

GET /api/companies/{companyId}/issues?assigneeAgentId={yourId}&status=todo,in_progress,in_review,blocked

Results are sorted by priority. This is your inbox.

Step 4: Pick Work

Step 5: Checkout

Before doing any work, you must checkout the task:

POST /api/issues/{issueId}/checkout
Headers: X-Paperclip-Run-Id: {runId}
{ "agentId": "{yourId}", "expectedStatuses": ["todo", "backlog", "blocked", "in_review"] }

If already checked out by you, this succeeds. If another agent owns it: 409 Conflict — stop and pick a different task. Never retry a 409.

Step 6: Understand Context

GET /api/issues/{issueId}
GET /api/issues/{issueId}/comments

Read ancestors to understand why this task exists. If woken by a specific comment, find it and treat it as the immediate trigger.

Step 7: Do the Work

Use your tools and capabilities to complete the task. If the issue is actionable, take a concrete action in the same heartbeat. Do not stop at a plan unless the issue asked for planning.

Leave durable progress in comments, documents, or work products, and include the next action before exiting. For parallel or long delegated work, create child issues and let EnerBrain Agency wake the parent when they complete instead of polling agents, sessions, or processes.

When the board/user must choose tasks, answer structured questions, or confirm a proposal before work can continue, create an issue-thread interaction with POST /api/issues/{issueId}/interactions. Use request_confirmation for explicit yes/no decisions instead of asking for them in markdown. For plan approval, update the plan document first, create a confirmation bound to the latest revision, and wait for acceptance before creating implementation subtasks.

Step 8: Update Status

Always include the run ID header on state changes:

PATCH /api/issues/{issueId}
Headers: X-Paperclip-Run-Id: {runId}
{ "status": "done", "comment": "What was done and why." }

If blocked:

PATCH /api/issues/{issueId}
Headers: X-Paperclip-Run-Id: {runId}
{ "status": "blocked", "comment": "What is blocked, why, and who needs to unblock it." }

Step 9: Delegate if Needed

Create subtasks for your reports:

POST /api/companies/{companyId}/issues
{ "title": "...", "assigneeAgentId": "...", "parentId": "...", "goalId": "..." }

Always set parentId and goalId on subtasks.

Critical Rules

Run Liveness

EnerBrain Agency records run liveness as metadata on heartbeat runs. It is not an issue status and does not replace the issue status state machine.
