Universal Task Creator

Worker that generates task documents and creates Linear issues for implementation, refactoring, or test tasks as instructed by orchestrators.

Purpose & Scope

• Owns all task templates and creation logic (Linear + kanban updates)
• Generates full task documents per type (implementation/refactoring/test)
• Enforces type-specific hard rules (no new tests in impl, regression strategy for refactoring, risk matrix and limits for test)
• Drops NFR bullets if supplied; only functional scope becomes tasks
• Never decides scope itself; uses orchestrator input (plans/results)

Task Storage Mode

File Mode task creation:

1. Determine next task number: count existing T*.md files + 1
2. Generate filename: T{NNN}-{slug}.md (e.g., T003-implement-auth-service.md)
3. Write task file using template
4. Add link to kanban_board.md under Story in Backlog section

Invocation (who/when)

• ln-300-task-coordinator: CREATE (no tasks) or ADD (appendMode) for implementation tasks.
• Orchestrators (other groups): Create refactoring or test tasks as needed.
• Never called directly by users.

Inputs

• Common: taskType, teamId, Story data (id/title/description with AC, Technical Notes, Context).
• Implementation CREATE: idealPlan (1-6 tasks), guideLinks.
• Implementation ADD: appendMode=true, newTaskDescription, guideLinks.
• Refactoring: codeQualityIssues, refactoringPlan, affectedComponents.
• Test: manualTestResults, testPlan (E2E 2-5, Integration 0-8, Unit 0-15, Priority ≤15), infra/doc/cleanup items.

Workflow (concise)

1. DRY Check (Codebase Scan): For EACH Task in plan:
   • Extract keywords: function type, component name, domain from Task description
   • Scan codebase: Grep(pattern="[keyword]", path="src/", output_mode="files_with_matches") for similar functionality
   • IF similar code found (≥70% keyword match):
     • Add ⚠️ DRY Warning section to Task description BEFORE Implementation Plan:

       > [!WARNING]
       > **DRY Check:** Similar functionality detected in codebase
       > - Existing: src/services/auth/validateToken.ts:15-42
       > - Similarity: 85% (function name, domain match)
       > - **Recommendation:** Review existing implementation before creating new code
       >   - Option 1: Reuse existing function (import and call)
       >   - Option 2: Extend existing function with new parameters
       >   - Option 3: Justify why reimplementation needed (document in Technical Approach)
       

   • IF no duplication → Proceed without warning
   • Rationale: Prevents code duplication BEFORE implementation starts
2. Template select: Load template based on taskType (see "Template Loading" section).
3. Generate docs: Fill sections for each task in plan/request using provided data, guide links, and DRY warnings.
4. Validate type rules: Stop with error if violation (see table below).
5. Preview: Show titles/goals/estimates/AC/components, DRY warnings count, and totals.
6. Confirmation required: Proceed only after explicit confirm.
7. Create issues: Call Linear create_issue with parentId=Story, state=Backlog; capture URLs.
8. Update kanban: Add under Story in Backlog with correct Epic/indent.
9. Return summary: URLs, counts, hours, guide link count, DRY warnings count; next steps (validator/executor).

Type Rules (must pass)

Critical Notes

• MANDATORY: Always pass state: "Backlog" when calling create_issue. Linear defaults to team's default status (often "Postponed") if not specified.
• DRY Check: Scan codebase for EACH Task before generation. If similar code found (≥70% keyword match) → add ⚠️ DRY Warning section with 3 options (reuse/extend/justify). Skip scan for test tasks (no implementation code).
• Foundation-First order for implementation is preserved from orchestrator; do not reorder.
• No code snippets; keep to approach, APIs, and pseudocode only.
• Documentation updates must be included in Affected Components/Docs sections.
• Language preservati
