## Detailed Scores

### Progressive Disclosure Architecture (28/30)

| Criterion | Score | Max | Assessment |
|-----------|-------|-----|------------|
| Token Economy | 9 | 10 | Excellent density with minimal prose; decision trees, tables, and code examples are highly efficient |
| Layered Structure | 10 | 10 | SKILL.md is perfect navigation hub with 17 focused reference files; clear separation of concerns |
| Reference Depth | 5 | 5 | All 17 references are exactly one level deep; no nested sub-references |
| Navigation Signals | 4 | 5 | TOCs present in long files; decision trees provide excellent wayfinding; some files exceed 500 lines |

### Ease of Use (24/25)

| Criterion | Score | Max | Assessment |
|-----------|-------|-----|------------|
| Metadata Quality | 10 | 10 | Name follows conventions; description is specific with clear scope and 30+ explicit triggers |
| Discoverability | 6 | 6 | Comprehensive trigger list covers AWS services, actions, and common tasks; activates appropriately |
| Terminology Consistency | 4 | 4 | Consistent terminology throughout; aws cli v2, bucket, role terms used uniformly |
| Workflow Clarity | 4 | 5 | Clear checklists for Cross-Account Setup and GitHub OIDC; Safe Deployment Checklist with numbered steps |

### Spec Compliance (15/15)

| Criterion | Score | Max | Assessment |
|-----------|-------|-----|------------|
| 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 | 4 | 4 | Imperative form throughout; no second-person; section headers use infinitives |
| Objectivity | 3 | 3 | Purely instructional; no marketing language; focuses on commands and patterns |
| Conciseness | 2 | 3 | Very dense but some reference files are quite long; could split largest files further |

### Utility (19/20)

| Criterion | Score | Max | Assessment |
|-----------|-------|-----|------------|
| Problem Solving Power | 8 | 8 | Addresses real gaps in AWS CLI usage; covers compute, storage, security, CI/CD comprehensively |
| Degrees Of Freedom | 5 | 5 | Appropriate constraints with copy-paste commands while allowing customization via placeholders |
| Feedback Loops | 3 | 4 | Waiters, verify commands, and troubleshooting sections provide validation; debug patterns included |
| Examples And Templates | 3 | 3 | Extensive input/output pairs; JSON policy templates; GitHub workflow YAML examples |

### 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 2)

### Issue 1: Reference file length

**Severity:** Low
**Location:** references/s3.md
**Pillar Affected:** PDA

**Problem:** S3 reference is 743 lines; could overwhelm context in token-constrained scenarios

**Current:**
```
Single comprehensive S3 reference file
```

**Suggested Rewrite:**
```
Split into s3-basics.md, s3-advanced.md, or use collapsible sections
```

**Impact:** +1 point

---

### Issue 2: Missing explicit allowed-tools rationale

**Severity:** Low
**Location:** SKILL.md:metadata
**Pillar Affected:** Ease of Use

**Problem:** allowed-tools list lacks inline explanation for why Read/Bash/WebFetch are needed

**Current:**
```
allowed-tools:\n  - Read\n  - Bash\n  - WebFetch
```

**Suggested Rewrite:**
```
Add brief comment or note explaining tool usage (e.g., Bash for CLI execution)
```

**Impact:** +0.5 points

---

## 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 |
| F | <60 | Major revision |
