# PRD Authoring Skill - Issue #107 Implementation Summary
## Issue Overview
**Issue #107**: Create comprehensive usage examples and test the complete PRD authoring workflow
**Assigned**: Implementation of examples, testing, and documentation for prd-authoring skill
## Deliverables Completed
### 1. Examples Directory Created

#### d. Workflow Test Log (`workflow-test-log.md`)
- **Scope**: Complete testing of all commands and edge cases
- **Test Coverage**:
- Happy path: All 7 commands tested successfully
- Edge cases: 10 scenarios tested (missing files, duplicates, invalid input)
- Validation quality: Tests for vague language, unmeasurable criteria, missing sections
- **Result**: ALL TESTS PASSED ✓
- **Value**: Proves skill is production-ready with robust error handling
#### e. Examples README (`README.md`)

#### Added Troubleshooting Section (Lines 1693-2110)
Comprehensive troubleshooting guide with 3 categories:
**Common Errors (9 issues)**:
1. Missing docs/prds directory
2. Product brief already exists
3. Project directory doesn't exist
4. Research document not found (warning)
5. Vague language detected
6. Unmeasurable success criteria
7. Missing acceptance criteria
8. Epics document already exists
9. Spec proposal directory already exists
**Quality Issues (4 issues)**:
1. PRD validation passes but requirements unclear
2. Epic dependencies complex and create bottlenecks
3. Stakeholders disagree on objectives
4. Research taking too long
**Integration Issues (2 issues)**:
1. Unclear how to transition from PRD to spec-authoring
2. Multiple people working on same PRD causing conflicts
Each issue includes:
- **Symptom**: What the user observes
- **Cause**: Why it happens
- **Solution**: Step-by-step fix with commands
- **Prevention**: How to avoid in future (where applicable)
### 3. Testing Completed
#### Happy Path Testing
**All 7 commands tested successfully**:
1. ✓ `status` - Works with and without project name
2. ✓ `brief` - Creates template with proper structure
3. ✓ `research` - Generates comprehensive research template
4. ✓ `create-prd` - Creates full PRD template
5. ✓ `validate-prd` - Detects quality issues accurately (strict & lenient modes)
6. ✓ `decompose` - Generates epic breakdown template
7. ✓ `generate-spec` - Creates spec proposal structure
#### Edge Case Testing
**10 edge cases tested, all handled correctly**:
1. ✓ Missing directories - Proper error messages
2. ✓ Duplicate files - Prevents overwriting
3. ✓ Missing prerequisites - Clear guidance provided
4. ✓ Invalid project names - Sanitization works
5. ✓ Incomplete documents - Warnings appropriate
6. ✓ Invalid commands - Help text displayed
7. ✓ Missing arguments - Usage guidance provided
8. ✓ Parallel projects - Proper isolation
9. ✓ Validation modes - Both work as expected
10. ✓ Epic generation - Handles missing epics gracefully
#### Validation Quality Testing
**Validation accurately detects**:
- Vague language (should, might, probably, good, fast)
- Unmeasurable criteria (qualitative without numbers)
- Missing sections (strict mode)
- Missing acceptance criteria
- YAML frontmatter issues
### 4. Example Project Statistics
**Payment Gateway Integration**:
- **Problem**: 45% cart abandonment, $2.4M lost revenue annually
- **Solution**: Stripe integration for real-time payments
- **Value**: $1.8M revenue recovery + $100K cost savings = 12x ROI
- **Timeline**: 6 months to launch (Q2 2026)
- **Team**: 2 FE, 1 BE, 1 QA engineer
- **Budget**: $150K (development + first year fees)
- **Scope**: 5 functional requirements, 4 NFRs
- **Expected Volume**: 1,000 → 5,000 transactions/month
