Metadata

  • Commit message type: feat
  • Scope: plans
  • Branch name prefix: feat/v3.3.0-subplan-spawning

Background and Context

As part of Epic #8489 (Subplan Spawning & Parallel Execution), plans must be able to spawn child subplans during execution. This enables complex tasks to be decomposed into parallel workstreams.

This issue blocks Epic #8489.

Expected Behavior

  • During plan execution, a plan action can spawn a child subplan
  • The child subplan is created with a reference to the parent plan
  • The parent plan tracks the child subplan's status
  • Subplan spawning is triggered by specific action types or task complexity

Acceptance Criteria

  • Plan execution can spawn child subplans via a spawn_subplan() action
  • Child subplans have a parent_plan_id reference
  • Parent plan tracks child subplan status (pending/running/complete/failed)
  • Integration tests verify subplan spawning during execution
  • Unit tests achieve >= 97% coverage

Subtasks

  • Implement spawn_subplan(spec, parent_plan_id) function
  • Add parent_plan_id field to Plan model
  • Implement parent plan status tracking for child subplans
  • Write integration tests for subplan spawning
  • Write unit tests for spawning logic

Definition of Done

  1. Subplan spawning is functional during plan execution
  2. Integration tests verify spawning and status tracking
  3. Unit tests pass with >= 97% coverage
  4. Code reviewed and merged to main branch

[AUTO-OWNR-2] Triage Decision (Cycle 2)

Status: Verified

MoSCoW: Must Have
Priority: Critical
Milestone: v3.3.0

Rationale: This is a required implementation task for the v3.3.0 milestone (Subplan Orchestration & Plan Correction). The v3.3.0 acceptance criteria explicitly requires plans to spawn child subplans during execution — this is the foundational feature that all other subplan orchestration work depends on.

Next Steps: Implementation worker should pick this up as part of the v3.3.0 epic work.
