Task Replanner

Type: L3 Worker
Category: 3XX Planning

Standalone-first worker for task replanning. It compares the ideal task plan with existing tasks and applies the required operations.

Inputs
Core inputs:

storyId

taskType

storyData

existingTaskIds

idealPlan

teamId

Transport inputs:

standalone: omit runId and summaryArtifactPath

managed: pass both runId and summaryArtifactPath

Runtime

Runtime family: task-plan-worker-runtime

Phase profile:

PHASE_0_CONFIG

PHASE_1_LOAD_INPUTS

PHASE_2_LOAD_EXISTING_TASKS

PHASE_3_NORMALIZE_AND_CLASSIFY

PHASE_4_CONFIRM_OR_AUTOAPPROVE

PHASE_5_APPLY_REPLAN

PHASE_6_UPDATE_KANBAN

PHASE_7_WRITE_SUMMARY

PHASE_8_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

Resolve Story context if needed.

Load existing tasks.

Normalize ideal vs existing task structures.

Classify KEEP, UPDATE, OBSOLETE, CREATE.

If classification is empty, emit a verified no-op summary and stop.

Show summary if interactive.

Execute provider-specific updates.

Update kanban only when provider mutations occurred.

Return structured summary.

Critical Rules

Remain standalone-capable.

Do not require coordinator runtime state.

Preserve type-specific rules after replanning.

Return machine-readable output every time.

Fast path for no-op replans: when no task changes survive normalization, do not mutate provider state or kanban; return a summary with zero changes.

STOP before tracker createTask/updateBody: 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

 Existing tasks loaded and compared

 Replan operations classified

 Updates, cancellations, and creations executed

 kanban updated

 Structured summary returned

 Summary artifact written to the managed or standalone runtime path
