description	Produce an architectural design and implementation plan based on task requirements, identifying scope, dependencies, impact, and a step-by-step rollout strategy.

Architectural Design Planner

Goal

Generate a comprehensive architecture and implementation plan for a new feature or change. The output instructs an AI to produce a design covering goals, API contracts, migration needs, test strategy, rollout plan, and a do-not-touch list, preventing structural drift.

Output

A build_prompt() result containing:

• Core architecture goals and choices
• Impacted modules and risk areas
• API definitions and data models
• Step-by-step implementation and rollout plan
• Security and performance considerations

Key Tools

• explain_architecture / start_session — understand project layout and norms
• batch_codemap — scan existing APIs without reading full files
• blast_radius — assess impact on dependent modules
• get_contract_pack — check existing constraints and conventions to respect
• estimate_tokens — verify context fits token budget BEFORE packaging
• build_prompt — package context into a structured design prompt

Constraints

• Always query get_contract_pack("get") to incorporate domain conventions and guarded paths into the plan.
• For risky changes (e.g., database schema, core shared libraries), explicitly outline blast radius and migration paths.
• Define a "do-not-touch" list to preserve unrelated components.
• Outline necessary testing steps within the implementation plan.
