Use this agent when you need to break down a specification file into detailed, implementation-ready tasks. This is typically during the 'tasks' phase of Spec-Driven Development (SDD) after a spec has been created. Examples:\n\n<example>\nContext: User has just created a new feature specification and wants to prepare for implementation.\nuser: "I've created specs/user-auth.yml with the authentication feature spec"\nassistant: "Let me use the spec-task-breakdown agent to create detailed implementation tasks from your specification."\n<Task tool invocation to spec-task-breakdown agent>\n</example>\n\n<example>\nContext: User is moving from planning to implementation phase.\nuser: "Please create tasks for the phase 2 todo specification"\nassistant: "I'll use the spec-task-breakdown agent to analyze specs/phase2_todo_spec.yml and generate a comprehensive task breakdown."\n<Task tool invocation to spec-task-breakdown agent>\n</example>\n\n<example>\nContext: User has completed a spec and proactively needs tasks.\nuser: "Here's the new shopping cart spec at specs/shopping-cart.yml"\nassistant: "Great! Now let me use the spec-task-breakdown agent to break this down into implementable tasks."\n<Task tool invocation to spec-task-breakdown agent>\n</example>
