Universal Task Replanner

Worker that re-syncs existing tasks to the latest requirements for any task type.

Purpose & Scope

• Load full existing task descriptions from Linear
• Compare them with orchestrator-provided IDEAL plan (implementation/refactoring/test)
• Decide operations (KEEP/UPDATE/OBSOLETE/CREATE) and execute
• Drop NFR items; only functional scope remains
• Update Linear issues and kanban_board.md accordingly

Task Storage Mode

MANDATORY READ: Load shared/references/tools_config_guide.md, shared/references/storage_mode_detection.md, and shared/references/input_resolution_pattern.md

Extract: task_provider = Task Management → Provider (linear | file).

Invocation (who/when)

• ln-300-task-coordinator: REPLAN mode when implementation tasks already exist.
• Orchestrators (other groups): Replan refactoring or test tasks as needed.
• Standalone: User invokes directly with storyId (resolved via Input Resolution Chain).

Inputs

Resolution: Story Resolution Chain. Status filter: In Progress, To Review

Additional inputs (from orchestrator or Story context):

• Common: taskType, teamId, Story data (id/title/description with AC, Technical Notes, Context), existingTaskIds.
• Implementation: idealPlan (1-8 tasks), guideLinks.
• Refactoring: codeQualityIssues, refactoringPlan, affectedComponents.
• Test: manualTestResults, testPlan (Priority ≥15, Usefulness Criteria), infra/doc/cleanup items.

Template Loading

MANDATORY READ: Load shared/references/template_loading_pattern.md for template copy workflow. Load shared/references/destructive_operation_safety.md for destructive operation keywords and severity classification.

Template Selection by taskType:

• implementation → task_template_implementation.md
• refactoring → refactoring_task_template.md
• test → test_task_template.md

Local copies: docs/templates/*.md (in target project)

Workflow (concise)

1. Resolve storyId: Run Story Resolution Chain per guide (status filter: [In Progress, To Review]).
2. Load templates per taskType (see Template Loading) and fetch full existing task descriptions.
3. Normalize both sides (IDEAL vs existing sections) and run replan algorithm to classify KEEP/UPDATE/OBSOLETE/CREATE.
   • Inherited Assumptions (UPDATE): Preserve Inherited Assumptions from parent Story. If parent Story Assumptions changed, update Inherited Assumptions in affected tasks to match current Story registry (ID + text sync).
   • Inherited Assumptions (CREATE): For new tasks, extract relevant assumptions from parent Story Assumptions table, add to Context > Inherited Assumptions using A{N} ({CATEGORY}) format.
   • Destructive Op Detection (UPDATE): After updating Implementation Plan, re-scan for keywords from destructive_operation_safety.md (loaded above). IF detected AND "Destructive Operation Safety" section missing → add section from shared reference template. IF section already present → preserve it.
   • Destructive Op Detection (CREATE): For new tasks, scan Implementation Plan for keywords from destructive_operation_safety.md (loaded above). IF detected → include "Destructive Operation Safety" section from shared reference template (MANDATORY). Fill all 5 fields + severity.
4. Present summary (counts, titles, key diffs). Confirmation required if running interactively.
5. Execute operations in Linear: update descriptions, cancel obsolete, create missing with state="Backlog", preserve parentId for updates.
6. Update kanban_board.md: remove canceled, add new tasks under Story in Backlog.
7. Return operations summary with URLs and warnings.

Type Rules (must hold after update)

Critical Notes

• MANDATORY: Always pass state: "Backlog" when creating new tasks (CREATE operation). Linear defaults to team's default status (often "Postponed") if not specified.
• Destructive Op Detection: Use keyword list from destructive_operation_safety.md (loaded above). If found after update/create → include Destructive Operation Safety section as MANDATORY.
• Foundation-First ordering from IDEAL plan is preserved; do not reorder.
• Language preservation: keep existing task language (EN/RU).
• No code snippets; keep to approach/steps/AC/components.
• If Story reality differs (component exists, column exists), propose Story correction to orchestrator.

Definition of Done

• Existing tasks loaded and parsed with correct template.
• IDEAL plan vs existing compared; operations classified.
• Type validation passed for all updated/created tasks.
• Operations executed in Linear (updates, cancels, creations) with parentId intact.
• kanban_board.md updated (Backlog) with correct Epic/Story/indentation.
• Summary returned (KEEP/UPDATE/OBSOLETE/CREATE counts, URLs, warnings).
