Overview

Property	Value
Workflow type	Linear
Library	App-runners
Version	1.0

Input Schema

Field	Type	Required	Default	Description
runner_group_uuid	uuid	Yes	—	UUID of the RunnerGroup whose EC2 environment is health-checked, picked from the organization's list of runner groups.
organization_uuid	uuid	Yes	—	UUID of the caller's organization, injected server-side from the authenticated request; scopes the operation to the correct tenant.
workflow_run_uuid	string	No	—	Engine workflow-run identifier forwarded by a parent step; not a platform entity foreign key despite the name.

Output Schema

Field	Type	Required	Default	Description
runner_group_uuid	uuid	No	—	UUID of the RunnerGroup this action operates on, picked from the organization's list of runner groups; echoed on output alongside terminal/error payloads.
organization_uuid	uuid	No	—	UUID of the caller's organization, injected server-side from the authenticated request; scopes the operation to the correct tenant. Echoed on output alongside terminal/error payloads.
runner_execution_uuid	uuid	No	—	UUID of the RunnerExecution this action operates on, picked from the organization's (optionally group-scoped) list of executions; echoed on output alongside terminal/error payloads.
workflow_uuid	string	No	—	Engine workflow-run identifier (or, for GitHub-Actions-triggered flows, an external GitHub Actions run id) associated with this record; not a platform entity foreign key despite the name. No source is attached since there is no list/query workflow for an internal run id.

initiated_at	string	No	—	—
completed_at	string	No	—	—
failed_at	string	No	—	—

error	string	No	—	—
error_type	string	No	—	—
actor_uuid	uuid	No	—	UUID of the user or service actor who triggered this action, injected server-side from the authenticated request when available; used for audit/attribution only. Optional — omitted for system or service-triggered actions with no human actor.
reason	string	No	—	—
workflow_run_uuid	string	No	—	Engine-stamped correlation/run id for this DAG execution (ADR-015/E1 plumbing), written into state_data by action_start; not a foreign key to any business entity. No source is attached since there is no list/query workflow for an internal run id.
retry_count	integer	No	—	—
