## Detailed Scores

### Progressive Disclosure Architecture (27/30)

| Criterion | Score | Max | Assessment |
|-----------|-------|-----|------------|
| Token Economy | 8 | 10 | SKILL.md is fairly concise but scripts section could be condensed; references are well-delegated |
| Layered Structure | 9 | 10 | Excellent separation with 8 reference files covering CLI, Firestore, triggers, patterns, security, auth, hosting, GCP |
| Reference Depth | 5 | 5 | All references are exactly one level deep from SKILL.md with no nested references |
| Navigation Signals | 5 | 5 | TOC in SKILL.md and all reference files; clear task navigation table for quick access |

### Ease of Use (22/25)

| Criterion | Score | Max | Assessment |
|-----------|-------|-----|------------|
| Metadata Quality | 8 | 10 | Comprehensive description with 30+ trigger terms but name 'using-firebase' uses banned 'using' prefix |
| Discoverability | 6 | 6 | Excellent trigger coverage including firebase, firestore, cloud functions, emulator, deploy, callable, scheduled |
| Terminology Consistency | 4 | 4 | Consistent use of '2nd gen' vs '1st gen'; 'callable' vs 'HTTP'; no terminology conflicts |
| Workflow Clarity | 4 | 5 | Clear numbered workflows for setup, Python functions, security rules, deployment; pre-deployment checklist |

### Spec Compliance (14/15)

| Criterion | Score | Max | Assessment |
|-----------|-------|-----|------------|
| Frontmatter Validity | 5 | 5 | Valid YAML with required fields |
| Name Conventions | 4 | 4 | Correct hyphen-case format |
| Description Quality | 3 | 4 | Only 1-2 trigger phrases |
| Optional Fields | 2 | 2 | Uses allowed-tools, metadata |

### Writing Style (8/10)

| Criterion | Score | Max | Assessment |
|-----------|-------|-----|------------|
| Voice And Tense | 3 | 4 | Mostly imperative but some descriptions use declarative; 'Run' and 'Start' commands are good |
| Objectivity | 3 | 3 | No marketing language; purely instructional content throughout skill and references |
| Conciseness | 2 | 3 | Good density but some code examples are verbose; manage_secrets.sh explanation could be tighter |

### Utility (18/20)

| Criterion | Score | Max | Assessment |
|-----------|-------|-----|------------|
| Problem Solving Power | 7 | 8 | Addresses real Firebase gaps with comprehensive trigger coverage, both languages, both generations |
| Degrees Of Freedom | 5 | 5 | Appropriate flexibility with script options, function configuration, and rule patterns |
| Feedback Loops | 3 | 4 | Pre-deployment checklist with validation steps; emulator testing section; dry-run options |
| Examples And Templates | 3 | 3 | Excellent code examples in TypeScript and Python; 4 asset templates provided |

### Modifiers Applied (+6)

**Penalties:** None
**Bonuses:** copy_paste_checklists (+2), grep_friendly_structure (+1), exemplary_examples (+2), gerund_style_name (+1)

## Critical Issues (Top 3)

### Issue 1: Banned name prefix

**Severity:** Medium
**Location:** SKILL.md:frontmatter
**Pillar Affected:** Ease of Use

**Problem:** Name uses 'using-' prefix which is banned per spec conventions

**Current:**
```
name: using-firebase
```

**Suggested Rewrite:**
```
name: firebase-development
```

**Impact:** +2 points

---

### Issue 2: Verbose script explanations

**Severity:** Low
**Location:** SKILL.md:106-116
**Pillar Affected:** PDA

**Problem:** manage_secrets.sh section has redundant explanation that could be in reference file

**Current:**
```
Manage Cloud Functions secrets for 2nd gen functions. Uses GCP Secret Manager for secure storage. Prefer this script...
```

**Suggested Rewrite:**
```
Move detailed explanation to references/cli-commands.md; keep only usage examples in SKILL.md
```

**Impact:** +1 point

---

### Issue 3: Missing error recovery guidance

**Severity:** Low
**Location:** SKILL.md:common-workflows
**Pillar Affected:** Utility

**Problem:** Workflows lack troubleshooting steps for common failures

**Current:**
```
1. Run scripts/init_project.sh 2. Copy templates...
```

**Suggested Rewrite:**
```
Add 'If X fails, check Y' notes after critical steps
```

**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 |
