Feature Specification: Refactor AST Generation Routes Workflow

Feature Branch: 002-refactor-ast-gen Created: 2025-09-22 Status: Draft Input: User description: "refactor ast gen routes workflow"

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
• L Avoid HOW to implement (no tech stack, APIs, code structure)
• =e 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:

1. Mark all ambiguities: Use [NEEDS CLARIFICATION: specific question] for any assumption you'd need to make
2. Don't guess: If the prompt doesn't specify something (e.g., "login system" without auth method), mark it
3. Think like a tester: Every vague requirement should fail the "testable and unambiguous" checklist item
4. 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

As a developer using the atomctl code generation system, I need the AST-based route generation workflow to be refactored so that it is more maintainable, extensible, and follows consistent patterns with other generation workflows in the system.

Acceptance Scenarios

1. Given a developer wants to generate route handlers from AST annotations, When they run the generation command, Then the system should correctly parse route definitions and generate appropriate handler code
2. Given existing route generation code has inconsistent patterns, When the refactoring is complete, Then all route generation should follow the same architectural patterns as other providers
3. Given the current system has duplicate logic, When the refactoring is complete, Then common functionality should be shared and DRY principles should be applied

Edge Cases

• What happens when the system encounters unsupported route annotations?
• How does the system handle conflicting route definitions?
• What occurs when there are circular dependencies between route handlers?

Requirements (mandatory)

Functional Requirements

• FR-001: System MUST parse route-related annotations from AST structures
• FR-002: System MUST generate route handler code based on parsed annotations
• FR-003: Users MUST be able to define route patterns and HTTP methods through annotations
• FR-004: System MUST integrate route generation with existing provider generation workflow
• FR-005: System MUST eliminate duplicate code between route generation and other generation workflows
• FR-006: System MUST follow consistent error handling patterns across all generation workflows
• FR-007: System MUST provide clear feedback when route generation fails or encounters issues

Example of marking unclear requirements:

• FR-008: System MUST support [NEEDS CLARIFICATION: which HTTP methods? GET, POST, PUT, DELETE, or all?]
• FR-009: Route generation MUST handle [NEEDS CLARIFICATION: what level of route complexity? simple paths, parameters, wildcards?]

Key Entities (include if feature involves data)

• Route Definition: Represents a route annotation containing path, HTTP method, and handler information
• Route Generator: Component responsible for transforming route annotations into executable code
• Route Parser: Component that extracts route information from AST structures
• Route Template: Code generation template that produces the final route handler code
