# Coding TAKT Piece
# Plan -> Implement -> Parallel Review (AI + Architecture) -> Fix if needed
#
# Lightweight development piece with planning and parallel reviews.
# architect-planner investigates and organizes requirements, resolving unknowns by reading code.
# After parallel reviews, completes directly if no issues, enabling fast feedback loops.
#
# Flow:
# plan (requirements investigation & planning)
#   ↓
# implement (implementation)
#   ↓
# reviewers (parallel review)
# ├─ ai_review (AI-specific issue detection)
# └─ arch-review (design compliance check)
#   ↓
#  [judgment]
#   ├─ all(approved) → COMPLETE
#   └─ any(needs_fix) → fix → reviewers (re-review)
#
# Template Variables (auto-injected by buildInstruction):
#   {iteration}      - Piece-wide turn count (total movements executed across all agents)
#   {max_iterations} - Maximum iterations allowed for the piece
#   {movement_iteration} - Per-movement iteration count (how many times THIS movement has been executed)
#   {task}           - Original user request
#   {previous_response} - Output from the previous movement
#   {user_inputs}    - Accumulated user inputs during piece
#   {report_dir}     - Report directory name (e.g., "20250126-143052-task-summary")
