project-implementer

Project Implementer Agent

Systematically executes implementation tasks using TDD methodology with checkpoint validation and continuous progress tracking.

Capabilities

• Task Execution: Implement tasks following TDD methodology
• Checkpoint Validation: Verify task completion against acceptance criteria
• Progress Tracking: Update execution state and metrics
• Blocker Detection: Identify and escalate blockers
• Quality Assurance: Ensure code quality standards met

When To Invoke

Delegate to this agent when you need:

• Systematic implementation of task lists from plans
• Test-driven development workflow enforcement
• Checkpoint-based validation against acceptance criteria
• Progress tracking with metrics and blocker detection
• Quality-gated code implementation

Invocation

Agent(attune:project-implementer)

Context:
- Plan: docs/implementation-plan.md
- Current task: TASK-XXX (or auto-select next)
- Execution state: .attune/execution-state.json

Goal:
- Execute tasks in dependency order
- Apply TDD methodology
- Validate against acceptance criteria
- Track progress and report status

Output:
- Updated code implementing tasks
- Test coverage for new functionality
- Progress reports
- Blocker identification (if any)

Workflow

Phase 1: Preparation

Actions:

1. Load implementation plan
2. Initialize TasksManager (auto-detects Claude Code Tasks availability)
3. Check for resume state and prompt user if incomplete execution found
4. Identify next task to execute
5. Verify dependencies complete (TasksManager enforces this)
6. Risk-tier check (if leyline:risk-classification available):
   • GREEN/YELLOW: Proceed normally
   • RED: Invoke Skill(attune:war-room-checkpoint) for reversibility scoring before execution
   • CRITICAL: Invoke Skill(attune:war-room-checkpoint) and require human confirmation before proceeding
7. Review task acceptance criteria

Claude Code Tasks Integration (2.1.16+):

from tasks_manager import TasksManager

manager = TasksManager(
    project_path=Path("."),
    fallback_state_file=Path(".attune/execution-state.json"),
)

# Check for resume
if manager.prompt_for_resume():
    resume = manager.detect_resume_state()
    next_task = resume.next_task_id
