### 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: Missing When Not to Use section in references

**Severity:** Low
**Location:** references/*.md
**Pillar Affected:** Utility

**Problem:** Reference files lack boundary definitions for when NOT to use specific service commands

**Current:**
```
Reference files jump straight into commands without scope limitations
```

**Suggested Rewrite:**
```
Add brief 'Scope' section at top of each reference noting what's NOT covered (e.g., SDK usage, CloudFormation)
```

**Impact:** +1 point

---

### Issue 2: GitHub CICD reference not visible in sampled files

**Severity:** Low
**Location:** references/github-cicd.md
**Pillar Affected:** PDA

**Problem:** Could not verify github-cicd.md content; navigation table references it but content depth unknown

**Current:**
```
File exists but not sampled
```

**Suggested Rewrite:**
```
Ensure github-cicd.md follows same comprehensive pattern as other references
```

**Impact:** +0 points (likely already good)

---

### Issue 3: JSON blocks could benefit from inline annotations

**Severity:** Low
**Location:** SKILL.md:common patterns, references/*.md
**Pillar Affected:** Writing Style

**Problem:** Large JSON policy blocks lack inline comments explaining key fields

**Current:**
```
Raw JSON with explanatory text before/after but not inline
```

**Suggested Rewrite:**
```
Add # comments within JSON (where supported) or JSONC format snippets for educational value
```

**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 |
| F | <60 | Major revision |
