| Token Economy | 9 | 10 | Main SKILL.md is concise with essential overview; references provide detailed implementation without fluff |
| Layered Structure | 9 | 10 | Clear overview in SKILL.md with decision trees and navigation to 17 detailed reference files |
| Reference Depth | 5 | 5 | All 17 references are exactly one level deep from SKILL.md in references/ directory |
| Navigation Signals | 5 | 5 | SKILL.md has TOC and clear headers; all reference files have structured navigation |

### Ease of Use (22/25)

| Criterion | Score | Max | Assessment |
|-----------|-------|-----|------------|
| Metadata Quality | 9 | 10 | Name follows conventions; description is specific with comprehensive trigger list covering major AWS services |
| Discoverability | 5 | 6 | Extensive trigger coverage for AWS services, but could include more deployment-specific triggers |
| Terminology Consistency | 4 | 4 | Consistent terminology throughout main file and all references |
| Workflow Clarity | 4 | 5 | Good numbered checklists and patterns, but some complex workflows could be clearer |

### Spec Compliance (15/15)

| Frontmatter Validity | 5 | 5 | Valid YAML with required fields |
| Name Conventions | 4 | 4 | Correct hyphen-case format |
| Description Quality | 4 | 4 | Third-person with good trigger coverage |
| Optional Fields | 2 | 2 | Uses allowed-tools, license, metadata |

### Writing Style (9/10)

| Criterion | Score | Max | Assessment |
|-----------|-------|-----|------------|
| Voice And Tense | 3 | 4 | Mostly imperative/infinitive form in main file, but some second-person language in references |
| Objectivity | 3 | 3 | Purely instructional content with no marketing language |
| Conciseness | 3 | 3 | Appropriate density for CLI reference without unnecessary fluff |

### Utility (18/20)

|-----------|-------|-----|------------|
| Problem Solving Power | 8 | 8 | Comprehensive coverage of AWS CLI operations across compute, storage, security, and deployment services |
| Degrees Of Freedom | 4 | 5 | Good flexibility for different use cases, but some advanced patterns could offer more options |
| Feedback Loops | 3 | 4 | Includes validation steps and waiters, but could have more run→check→fix patterns in complex operations |
| Examples And Templates | 3 | 3 | Rich examples with input/output pairs and comprehensive templates for trust policies and configurations |

### Modifiers Applied (+4)

**Penalties:** deeply_nested_references (-2)
**Bonuses:** grep_friendly_structure (+1), exemplary_examples (+2), explicit_scope_boundaries (+1), trigger_phrases_4plus (+1), gerund_style_name (+1)

---

## Critical Issues (Top 3)

### Issue 1: Second-person language in references

**Severity:** Medium
**Location:** references/ files (multiple)
**Pillar Affected:** Writing Style

**Problem:** Some references use second-person language like 'You can...' instead of imperative form

**Current:**
```
You can create a function with...
```

**Suggested Rewrite:**
```
Create a function with...
```

**Impact:** +1 point

---

### Issue 2: Inconsistent checklist formatting

**Severity:** Low
**Location:** references/iam-security.md
**Pillar Affected:** Ease of Use

**Problem:** Cross-account role setup checklist uses inconsistent formatting compared to other checklists

**Current:**
```
[ ] 1. Create trust-policy.json...
```

**Suggested Rewrite:**
```
Standardize checklist format across all references
```

**Impact:** +1 point

---

### Issue 3: Limited feedback loops in deployment workflows

**Severity:** Medium
**Location:** references/github-cicd.md
**Pillar Affected:** Utility

**Problem:** GitHub Actions workflows lack explicit validation steps before deployment

**Current:**
```
Deploy to S3 without pre-deployment checks
```

**Suggested Rewrite:**
```
Add validation steps like 'Verify AWS credentials' before deployment actions
```

**Impact:** +1 point

---

## General Recommendations

1. Add trigger phrases to description for discoverability
2. Add table of contents for files over 100 lines

---

## Grade Scale

| Grade | Score | Description |
|-------|-------|-------------|
| A | 90-100 | Production-ready |
| B | 80-89 | Good, minor work |
| C | 70-79 | Adequate, gaps |
| D | 60-69 | Needs work |
