Task Creator

Type: L3 Worker Category: 3XX Planning

Standalone-first worker for task creation. It creates tasks from an already approved plan and returns a stable summary contract.

MANDATORY READ: Load references/coordinator_summary_contract.md and references/task_plan_worker_runtime_contract.md MANDATORY READ: Load references/environment_state_contract.md, references/storage_mode_detection.md, references/template_loading_pattern.md, references/creation_quality_checklist.md, and references/destructive_operation_safety.md

Inputs

Core inputs:

• taskType
• storyData
• idealPlan — task list with scopes, AC mappings, dependencies, layer classifications
• teamId
• guideLinks

Coordinator context (passed in ADD/CREATE mode):

• traceabilityTablePath — materialized traceability table from coordinator Phase 2
• discoveryContext — architecture, tech stack, key files, integration points from coordinator Phase 1
• tasksToCreate — specific tasks to create (ADD mode). Worker writes the 7-section document, does not decide whether tasks are needed.

Transport inputs:

• standalone: omit runId and summaryArtifactPath
• managed: pass both runId and summaryArtifactPath

Runtime

Runtime family: task-plan-worker-runtime

Phase profile:

1. PHASE_0_CONFIG
2. PHASE_1_LOAD_INPUTS
3. PHASE_2_LOAD_CONTEXT
4. PHASE_3_GENERATE_TASK_DOCS
5. PHASE_4_VALIDATE_TASKS
6. PHASE_5_CONFIRM_OR_AUTOAPPROVE
7. PHASE_6_APPLY_CREATE
8. PHASE_7_UPDATE_KANBAN
9. PHASE_8_WRITE_SUMMARY
10. PHASE_9_SELF_CHECK

Summary artifact rules:

• emit summary_kind=task-plan
• standalone runs generate their own run_id and write the default worker-family artifact path
• managed runs require both runId and summaryArtifactPath and must write the summary to the exact provided path
• always write the validated summary artifact before terminal outcome

Output Contract

Always build a structured task-plan summary envelope per:

• references/coordinator_summary_contract.md
• references/task_plan_worker_runtime_contract.md

Payload fields:

• mode
• story_id
• task_type
• tasks_created
• tasks_updated
• tasks_canceled
• task_urls
• kanban_updated
• dry_warnings_count
• warnings

Always write the validated summary before terminal outcome.

Workflow

1. Resolve task provider and template set.
2. Run DRY and destructive-operation checks where applicable.
3. Use coordinator context (discoveryContext, traceabilityTablePath) to understand architecture. Research codebase for implementation details (existing patterns, related files, integration points) to write good Technical Approach sections.
4. Select scope:
   • ADD: use tasksToCreate only
   • CREATE: expand the full idealPlan
5. Generate task documents from the selected scope.
6. Validate type-specific rules.
7. Show preview and get confirmation if needed.
8. Create tasks via the configured tracker provider.
9. Update kanban.
10. Return structured summary.

Critical Rules

• Remain standalone-capable.
• Do not require coordinator runtime state.
• Keep implementation, refactoring, and test rules separated by taskType.
• Write machine-readable summary output every time.
• Ideal plan is binding. Create every task in the approved plan. Do not re-evaluate whether tasks should exist.
• Fast path for ADD: tasksToCreate is the execution scope. Do not re-expand the full ideal plan when the coordinator already selected the delta.
• STOP before tracker createTask: verify all 7 sections present in body: Context, Implementation Plan, Technical Approach, Acceptance Criteria, Affected Components, Existing Code Impact, Definition of Done. PreToolUse hook will BLOCK creation without them.

Definition of Done

• Templates loaded
• Task documents generated
• Type-specific validation passed
• Tasks created in provider-specific storage
• kanban updated
• Structured summary returned
• Summary artifact written to the managed or standalone runtime path
