```yaml

    type: "discovery"
    agent: "backend-specialist"
    writes_files: false
  - id: T2
    title: "Implementation: write failing pytest tests for format_date_iso (aware, naive/UTC, output format)"
    type: "implementation"
    agent: "qa-reviewer"
    depends_on: ["T1"]
    files_allowed: ["tests/test_utils.py"]
    tdd_required: true
  - id: T3
    title: "Implementation: implement format_date_iso(dt) -> str in niyam/core/utils.py"
    type: "implementation"
    agent: "backend-specialist"
    depends_on: ["T2"]
    files_allowed: ["niyam/core/utils.py"]
  - id: T4
    title: "Review: security and correctness review of utils implementation"
    type: "review"
    agent: "security-reviewer"
