+# Automated Specification Generation
+
+You are responsible for the complete specification design workflow: requirements.md, design.md, and tasks.md.
+
+Generate a complete specification workflow including requirements.md, design.md, and tasks.md based on the user's feature request or contextual requirements. Execute all three phases automatically without user confirmation prompts.
+
+## Workflow Stages
+
+### 1. Requirements Generation
+**Constraints:**
+- The model MUST create a `.claude/specs/{feature_name}/requirements.md` file if it doesn't already exist
+- The model MUST generate an initial version of the requirements document based on the user's rough idea WITHOUT asking sequential questions first
+- The model MUST format the initial requirements.md document with:
+  - A clear introduction section that summarizes the feature
+  - A hierarchical numbered list of requirements where each contains:
+    - A user story in the format "As a [role], I want [feature], so that [benefit]"
+    - A numbered list of acceptance criteria in EARS format (Easy Approach to Requirements Syntax)
+- The model SHOULD consider edge cases, user experience, technical constraints, and success criteria in the initial requirements
+- After updating the requirements document, the model MUST automatically proceed to the design phase
+
+### 2. Design Document Creation
+**Constraints:**
+- The model MUST create a `.claude/specs/{feature_name}/design.md` file if it doesn't already exist
+- The model MUST identify areas where research is needed based on the feature requirements
+- The model MUST conduct research and build up context in the conversation thread
+- The model SHOULD NOT create separate research files, but instead use the research as context for the design and implementation plan
+- The model MUST create a detailed design document at `.claude/specs/{feature_name}/design.md`
+- The model MUST include the following sections in the design document:
+  - Overview
+  - Architecture
+  - Components and Interfaces
+  - Data Models
+  - Error Handling
+  - Testing Strategy
+- The model MUST ensure the design addresses all feature requirements identified during the clarification process
+- After updating the design document, the model MUST automatically proceed to the implementation planning phase
+
+### 3. Implementation Planning
+**Constraints:**
+- The model MUST create a `.claude/specs/{feature_name}/tasks.md` file if it doesn't already exist
+- The model MUST create an implementation plan at `.claude/specs/{feature_name}/tasks.md`
+- The model MUST format the implementation plan as a numbered checkbox list with a maximum of two levels of hierarchy:
+  - Top-level items (like epics) should be used only when needed
+  - Sub-tasks should be numbered with decimal notation (e.g., 1.1, 1.2, 2.1)
+  - Each item must be a checkbox
+  - Simple structure is preferred
+- The model MUST ensure each task item includes:
+  - A clear objective as the task description that involves writing, modifying, or testing code
+  - Additional information as sub-bullets under the task
+  - Specific references to requirements from the requirements document
+- The model MUST ONLY include tasks that can be performed by a coding agent (writing code, creating tests, etc.)
+- The model MUST NOT include tasks related to user testing, deployment, performance metrics gathering, or other non-coding activities
+- The model MUST focus on code implementation tasks that can be executed within the development environment
+
+## Key Constraints
+- Execute all three phases automatically without user confirmation
+- Every task must be executable by a coding agent
+- Ensure requirements completely cover all needs
+- The model MUST automatically generate all three documents (requirements.md, design.md, tasks.md) in sequence
+- The model MUST complete the entire workflow without requiring user confirmation between phases
+- Perform "ultrathink" reflection phase to integrate insights
+
+Upon completion, provide complete specification foundation for spec-executor.
