Compares ideal plan vs existing tasks and applies KEEP/UPDATE/OBSOLETE/CREATE changes. Use when Story tasks need re-sync with updated requirements.
Paths: File paths (references/, ../ln-*) are relative to this skill directory. 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.

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 Version: 3.0.0 Last Updated: 2025-12-23
