Email Quality System
One skill, 7 modes. Score email/notification design, fix issues, or run the full loop.
Modes
| Mode | Trigger | What It Does | |------|---------|--------------| | score | "score my email", "audit notifications" | 10-category audit -> scorecard with grade (A+ to F) | | fix | "fix email issues", provide a scorecard | Parse scorecard -> prioritize -> apply fixes -> verify | | loop | "score and fix until B+", "email loop" | Run score, then fix, then re-score until target grade reached | | generate | Create new code | Load criteria -> Generate meeting all 10 -> Self-check | | review | Quick 1-2 file check | Read files -> Score applicable categories -> Annotate + fix | | migrate | Framework upgrade | Detect versions -> Map breaking changes -> Migrate -> Verify | | test | Generate test cases | Map categories to assertions -> Generate test files |
Mode: Score
Audit any email system against 10 weighted categories. Score 0-100 with letter grade and prioritized issues list.
Load references/scoring/scoring-workflow.md for the full 6-step process.
| # | Category | Weight | Criteria Reference |
|---|----------|--------|--------------------|
| 1 | Transactional Email | 15% | scoring/criteria/transactional-delivery.md |
| 2 | Email Templates & Rendering | 12% | scoring/criteria/templates-rendering.md |
| 3 | Notification Queue & Delivery | 12% | scoring/criteria/transactional-delivery.md |
| 4 | Email Provider Integration | 12% | scoring/criteria/provider-integration.md |
| 5 | Deliverability & Reputation | 10% | scoring/criteria/security-compliance.md |
| 6 | Bounce & Complaint Handling | 10% | scoring/criteria/security-compliance.md |
| 7 | Email Auth (SPF/DKIM/DMARC) | 8% | scoring/criteria/security-compliance.md |
| 8 | Rate Limiting & Throttling | 8% | scoring/criteria/security-compliance.md |
| 9 | Analytics & Tracking | 7% | scoring/criteria/provider-integration.md |
| 10 | Testing & Preview | 6% | scoring/criteria/templates-rendering.md |
Grades
| Grade | Score | Grade | Score | Grade | Score | |-------|-------|-------|-------|-------|-------| | A+ | 97-100 | B+ | 87-89 | C+ | 77-79 | | A | 93-96 | B | 83-86 | C | 73-76 | | A- | 90-92 | B- | 80-82 | D | 60-72 | | | | | | F | <60 |
Issue Severity
| Severity | Criteria | Action | |----------|----------|--------| | CRITICAL | Score 0-3 or security risk | Fix before deploy | | HIGH | Score 4-5 | Fix in current sprint | | MEDIUM | Score 6-7 | Fix next sprint | | LOW | Score 8 | Backlog |
Mode: Fix
Take a scorecard and systematically implement all fixes. Prioritize by severity * weight.
Load references/fix/implementation-workflow.md for the full 6-step process.
| Priority | Severity | Score Range | Action | |----------|----------|-------------|--------| | 1 | CRITICAL | 0-3 or security risk | Fix immediately -- blocks deploy | | 2 | HIGH + high weight (>=12%) | 4-5 | Fix next -- moves score most | | 3 | HIGH + low weight (<12%) | 4-5 | Fix after high-weight items | | 4 | MEDIUM | 6-7 | Fix next sprint | | 5 | LOW | 8 | Backlog or skip |
Fix Category -> Reference
| Scorecard Category | Fix Pattern Reference |
|-------------------|----------------------|
| Transactional Email, Notification Queue | fix/fix-patterns/transactional-delivery.md |
| Email Templates, Testing & Preview | fix/fix-patterns/templates-rendering.md |
| Email Provider, Analytics & Tracking | fix/fix-patterns/provider-integration.md |
| Deliverability, Bounce, Auth, Rate Limiting | fix/fix-patterns/security-compliance.md |
Verification
Load references/fix/verification.md for post-fix checklist, re-scoring protocol, and comparison template.
Mode: Loop
Automated score-fix cycle. Runs score -> fix -> re-score until target grade is met.
- Score the email system (Mode: Score)
- If grade < target, fix all CRITICAL + HIGH issues (Mode: Fix)
- Re-score and compare
- Repeat until target grade reached or no score improvement between iterations
Default target: B+ (87+). Override with "loop until A-" or similar.
- Max 5 iterations
- Stop on plateau (score unchanged after full fix cycle)
Mode: Generate
Generate code meeting all 10 categories at 9-10/10. Load references/generate/workflow.md.
Parse request -> Load criteria -> Generate with all patterns -> Self-check -> Output (assets/templates/generated-code.md.template)
Mode: Review
Quick 1-2 file review. Load references/review/workflow.md.
Read files -> Score applicable categories -> Annotate line numbers -> Suggest fixes (assets/templates/review-report.md.template)
Mode: Migrate
Upgrade code for framework changes. Load references/migrate/workflow.md.
Detect versions -> Map breaking changes -> Apply migrations -> Verify (assets/templates/migration-report.md.template)
Mode: Test
Generate tests from scoring criteria. Load references/test/workflow.md.
Map categories to assertions -> Generate tests -> Output suite (assets/templates/test-suite.md.template)
