Feature Specification: [FEATURE NAME]
Feature Branch: [###-feature-name]
Created: [DATE]
Status: Draft
Input: User description: "$ARGUMENTS"
Execution Flow (main)
1. Parse user description from Input
→ If empty: ERROR "No feature description provided"
2. Extract key concepts from description
→ Identify: actors, actions, data, constraints
3. For each unclear aspect:
→ Mark with [NEEDS CLARIFICATION: specific question]
4. Fill User Scenarios & Testing section
→ If no clear user flow: ERROR "Cannot determine user scenarios"
5. Generate Functional Requirements
→ Each requirement must be testable
→ Mark ambiguous requirements
6. Identify Key Entities (if data involved)
7. Run Review Checklist
→ If any [NEEDS CLARIFICATION]: WARN "Spec has uncertainties"
→ If implementation details found: ERROR "Remove tech details"
8. Return: SUCCESS (spec ready for planning)
⚡ Quick Guidelines
- ✅ Focus on WHAT users need and WHY
- ❌ Avoid HOW to implement (no tech stack, APIs, code structure)
- 👥 Written for business stakeholders, not developers
Section Requirements
- Mandatory sections: Must be completed for every feature
- Optional sections: Include only when relevant to the feature
- When a section doesn't apply, remove it entirely (don't leave as "N/A")
For AI Generation
When creating this spec from a user prompt:
- Mark all ambiguities: Use [NEEDS CLARIFICATION: specific question] for any assumption you'd need to make
- Don't guess: If the prompt doesn't specify something (e.g., "login system" without auth method), mark it
- Think like a tester: Every vague requirement should fail the "testable and unambiguous" checklist item
- Common underspecified areas:
- User types and permissions
- Data retention/deletion policies
- Performance targets and scale
- Error handling behaviors
- Integration requirements
- Security/compliance needs
User Scenarios & Testing (mandatory)
Primary User Story
[Describe the main user journey in plain language]
Acceptance Scenarios
- Given [initial state], When [action], Then [expected outcome]
- Given [initial state], When [action], Then [expected outcome]
Edge Cases
- What happens when [boundary condition]?
- How does system handle [error scenario]?
Requirements (mandatory)
Functional Requirements
- FR-001: System MUST [specific capability, e.g., "allow users to create accounts"]
- FR-002: System MUST [specific capability, e.g., "validate email addresses"]
- FR-003: Users MUST be able to [key interaction, e.g., "reset their password"]
- FR-004: System MUST [data requirement, e.g., "persist user preferences"]
- FR-005: System MUST [behavior, e.g., "log all security events"]
Example of marking unclear requirements:
- FR-006: System MUST authenticate users via [NEEDS CLARIFICATION: auth method not specified - email/password, SSO, OAuth?]
- FR-007: System MUST retain user data for [NEEDS CLARIFICATION: retention period not specified]
Key Entities (include if feature involves data)
- [Entity 1]: [What it represents, key attributes without implementation]
- [Entity 2]: [What it represents, relationships to other entities]
