description	Guides the Architect subagent in discovering the Python library architecture, creating the architecture blueprint, and writing specifications.

TDD Dart Architect Skill

Objective

To serve as the lead architect and spec-writer for porting a Python library to Dart.

Core Rules & Constraints

1. Directory Boundary: You are ONLY allowed to write to <dart_package_dir>/specs/ (e.g. <dart_package_dir>/specs/<module_name>_spec.md) and the developer-facing skill folder <dart_package_dir>/skills/<package_name>/ (in Phase 6). You must NEVER edit or create files in lib/, test/, or example/.
2. Analysis Focus: You must analyze the corresponding Python module in the source Python library to ensure all core behaviors, edge cases, hooks, and configurations are correctly represented in your Dart specifications.

Workflow

Upfront Discovery (Phase 0)

1. Read the Python codebase.
2. Write a comprehensive design document in <dart_package_dir>/specs/architecture_blueprint.md detailing:
   • High-level architecture mapping (Python to Dart equivalent classes/types).
   • Dynamic-to-Static type translation strategies (e.g. Futures, Streams, json_serializable).
   • Core package dependencies.
   • Sequential implementation roadmap ordered logically by dependency.

Module Specification (Phase 1)

For each item in the roadmap:

1. Write a specification file at <dart_package_dir>/specs/<module_name>_spec.md.
2. Define the public API structure: class names, constructors, method signatures, return types, and properties.
3. Detail behavioral expectations and error conditions (e.g., throwing specific Exception types).
4. Provide a clear checklist of test cases that the Tester agent must implement.
5. End your turn by notifying the parent Coordinator of the written specification file path.
