Spec Template

# Feature/Refactor Name

**Date**: YYYY-MM-DD  
**Status**: 📋 PLANNING  
**Related**: `other_spec.md` (optional)

## Problem Statement

What problem are we solving? Why does this matter?

## Solution

What are we trying to achieve? High-level approach.

## Implementation Plan

1. Step one
2. Step two
3. Step three

## Success Criteria

- [ ] Criterion 1
- [ ] Criterion 2
- [ ] Criterion 3

File Naming

Format: YYYYMMDD_HHMMSS_description.md

Examples:

  • 20251230_143000_worker_autoscaling.md
  • 20251228_091500_data_quality_audit.md

Code in Specs

Use high-level pseudo-code, NOT full implementations.

# GOOD: Show structure and intent
class BulkDownloadService:
    async def download_files(self, files: List[FileInfo]) -> Result:
        # Separate large vs small files
        # Use semaphore for concurrency control
        # Download with resume capability
        # Return success/failure status

# BAD: Full implementation with all imports, error handling, etc.

Guidelines:

  • Show class structure and method signatures
  • Use comments to explain intent
  • Show data flow: job_a → result → job_b
  • Avoid: imports, complete error handling, edge cases

Status Values

Status Meaning When to Use
📋 PLANNING Not started Initial creation
📝 IN PROGRESS Active work Implementation started
✅ COMPLETED Done and tested All criteria met
📚 REFERENCE Documentation only Not an implementation spec

Workflow

  1. Create: Write spec with PLANNING status
  2. Start: Update to IN PROGRESS when work begins
  3. Complete: Update to COMPLETED when all success criteria met
  4. Sync: Update related code/docs

Completion Checklist

When marking COMPLETED:

  • All success criteria met
  • Code follows the spec
  • Tests added (if applicable)
  • Related docs updated
  • Add completion notes (date, deviations, results)
