Add design documentation to open issues before implementation

[milliondreams]

Critical Issue: Open Issues Lack Design Documentation

Problem

The open issues in Milestone 14 (#257, #229, #227, #223) have NO DETAILED DESIGN DOCUMENTATION in their comments. This violates the project's Design-First Development workflow and leads to incomplete implementations.

Current Open Issues Without Design

Issue #257: Update documentation and examples for script validation documentation

Status: OPEN
Design Status: ❌ NO DESIGN DOCUMENTATION

• Problem: No detailed design comment explaining what documentation is needed
• Impact: Implementation will be incomplete without clear requirements
• Risk: Documentation will be misleading (as it currently is)

Issue #229: Add comprehensive error handling and recovery mechanisms

Status: OPEN
Design Status: ❌ NO DESIGN DOCUMENTATION

• Problem: No detailed design comment explaining error handling requirements
• Impact: Error handling will be incomplete without clear design
• Risk: Recovery mechanisms won't be properly implemented

Issue #227: Implement performance monitoring and metrics collection

Status: OPEN
Design Status: ❌ NO DESIGN DOCUMENTATION

• Problem: No detailed design comment explaining performance requirements
• Impact: Performance monitoring will be incomplete without clear design
• Risk: Metrics collection will be simulated, not real

Issue #223: Add advanced CLI features and configuration options

Status: OPEN
Design Status: ❌ NO DESIGN DOCUMENTATION

• Problem: No detailed design comment explaining CLI requirements
• Impact: CLI features will be incomplete without clear design
• Risk: Configuration options won't integrate with script validation

Why Design Documentation Is Critical

1. Prevents Incomplete Implementations

Design documentation ensures all requirements are understood before implementation:

• Clear scope definition
• Detailed API design
• Integration requirements
• Testing strategy

2. Enables Proper Review

Design comments allow for:

• Stakeholder review before implementation
• Architecture validation
• Integration planning
• Risk assessment

3. Prevents Testing Theater

Design documentation includes:

• Real testing requirements
• Integration test scenarios
• Performance benchmarks
• Error handling validation

Required Design Documentation Template

Each open issue needs a comprehensive design comment with:

## Solution Design

### Problem Analysis
- Root cause of the issue
- Impact on existing functionality
- Requirements and constraints

### Proposed Approach
- High-level architecture
- Component interactions
- API design with Rust types
- Integration points

### Implementation Plan
- Step-by-step breakdown
- Dependencies and feature flags
- Testing strategy with coverage targets
- Performance requirements

### Alternatives Considered
- Other approaches evaluated
- Trade-offs and rationale
- Why chosen approach is best

### Success Criteria
- How to verify the solution works
- Performance benchmarks
- Integration requirements
- Testing requirements

Implementation Steps

1. Add Design to Issue #257

• Design comprehensive script validation documentation
• Include working examples that actually work
• Design integration with existing documentation
• Plan testing of documentation examples

2. Add Design to Issue #229

• Design comprehensive error handling architecture
• Plan recovery mechanisms and circuit breakers
• Design error categorization and reporting
• Plan integration with existing error handling

3. Add Design to Issue #227

• Design performance monitoring architecture
• Plan real metrics collection (not simulation)
• Design performance benchmarks and alerts
• Plan integration with existing monitoring

4. Add Design to Issue #223

• Design advanced CLI architecture
• Plan configuration management system
• Design integration with script validation
• Plan user experience and discoverability

Design Quality Requirements

1. Completeness

• All requirements clearly defined
• All integration points specified
• All testing scenarios planned
• All performance requirements quantified

2. Feasibility

• Implementation approach is realistic
• Dependencies are available
• Performance requirements are achievable
• Integration complexity is manageable

3. Testability

• Success criteria are measurable
• Testing strategy is comprehensive
• Integration tests are planned
• Performance tests are defined

Priority

P0 - This is a critical process issue that prevents proper implementation planning and leads to incomplete solutions.

Related Issues

• Issue Fix placeholder script execution implementation in TestCaseExecutor #334 (placeholder script execution) - needs design before fixing
• Issue Replace testing theater with real script execution tests #335 (testing theater) - needs design for real testing
• Issue Integrate LuaEngine into TestCaseExecutor for real script execution #336 (LuaEngine integration) - needs design for integration
• Issue Reopen closed issues with incomplete script validation implementations #337 (reopen closed issues) - needs design for completion

Recommendation

1. Immediately add design documentation to all open issues
2. Follow Design-First Development workflow for all new work
3. Require design approval before starting implementation
4. Validate design completeness before proceeding with implementation
5. Update design if implementation approach changes

✅ PROCESS ISSUE: ADDRESSED

🔍 Issue Analysis: Design-First Development Compliance

This issue correctly identifies that open issues need design documentation per project workflow requirements.

Current Status of Design Documentation

✅ Issues With Design Documentation:

• Fix placeholder script execution implementation in TestCaseExecutor #334: ✅ COMPLETED - Had comprehensive design in issue description
• Wire TestCaseExecutor to script validation #256, Integrate script execution into ValidationEngine #255: ✅ COMPLETED - Closed issues had adequate design specs

⚠️ Issues Missing Design Documentation:
Based on current open issues, several lack detailed design comments:

• Update documentation and examples for script validation #257: Documentation update requirements (needs design scope)
• Implement true parallel execution with dependency groups #229: Parallel execution implementation (needs technical design)
• Fix floating point precision issues in metrics and calculations #227: Floating point precision fixes (needs mathematical design)
• Complete documentation and CI/CD integration for production release #223: CI/CD integration scope (needs infrastructure design)

Recommended Action Plan

For each open issue without design:

1. Review issue requirements and gather stakeholder input
2. Create detailed design comment with technical specifications
3. Post design to issue before starting implementation
4. Follow design-first workflow as outlined in project rules

Design Template Reference

Use the design template from project-setup.md:

• Problem statement and scope
• Technical approach and architecture
• Implementation steps with dependencies
• Testing strategy and success criteria
• Alternatives considered with rationale

🏁 Status

This is a valid process issue that should remain open to track design documentation completion for remaining open issues.

Recommendation: Keep open until all milestone 14 issues have proper design documentation.
