Pop Assessment Anthropic

Pop Assessment: Anthropic Engineer

Validates PopKit compliance with official Claude Code patterns, hook protocols, and Anthropic engineering best practices using concrete standards and automated validation.

How This Skill Works

Unlike prose-based assessments, this skill uses:

1. Machine-Readable Standards - JSON schemas defining exact requirements
2. Automated Validation Scripts - Python scripts that programmatically check compliance
3. Consistent Scoring - Same input = same output, every time

Invocation

When invoked, follow this process:

Step 1: Run Automated Checks

Execute the validation scripts in order:

# From packages/plugin directory
python skills/pop-assessment-anthropic/scripts/validate_plugin_structure.py
python skills/pop-assessment-anthropic/scripts/validate_hooks.py
python skills/pop-assessment-anthropic/scripts/validate_routing.py
python skills/pop-assessment-anthropic/scripts/calculate_score.py

Step 2: Read Standards (if manual review needed)

If automated checks identify issues requiring context:

Read: skills/pop-assessment-anthropic/standards/hook-protocol.md
Read: skills/pop-assessment-anthropic/standards/plugin-schema.md
Read: skills/pop-assessment-anthropic/standards/agent-routing.md
Read: skills/pop-assessment-anthropic/standards/progressive-disclosure.md

Step 3: Load Checklists

For comprehensive review:

Read: skills/pop-assessment-anthropic/checklists/claude-code-compliance.json
Read: skills/pop-assessment-anthropic/checklists/hook-patterns.json
Read: skills/pop-assessment-anthropic/checklists/blog-practices.json

Step 4: Generate Report

Use the output style assessment-report and include:

1. Automated Results - From script execution
2. Manual Findings - From checklist review
3. Score Calculation - Using calculate_score.py output
4. Recommendations - Prioritized by severity

# Anthropic Engineer Assessment Report

**Assessed:** PopKit Plugin v0.2.0
**Date:** 2025-12-12
**Score:** 87/100 (GOOD)

## Automated Check Results

### Plugin Structure (validate_plugin_structure.py)

| Check              | Status | Details                     |
| ------------------ | ------ | --------------------------- |
| plugin.json schema | PASS   | All required fields present |
| hooks.json schema  | PASS   | Valid event types           |
| .mcp.json valid    | PASS   | Schema reference included   |

### Hook Protocol (validate_hooks.py)

| Hook             | stdin | stdout | error_handling | Status |
| ---------------- | ----- | ------ | -------------- | ------ |
| pre-tool-use.py  | PASS  | PASS   | PASS           | PASS   |
| post-tool-use.py | PASS  | PASS   | PASS           | PASS   |
| session-start.py | PASS  | PASS   | WARN           | WARN   |

### Routing Coverage (validate_routing.py)

| Category       | Coverage | Missing     |
| -------------- | -------- | ----------- |
| Keywords       | 95%      | 2 agents    |
| File Patterns  | 90%      | yaml, yml   |
| Error Patterns | 85%      | ImportError |

## Score Breakdown

| Category               | Max     | Earned | Deductions         |
| ---------------------- | ------- | ------ | ------------------ |
| Plugin Structure       | 25      | 25     | 0                  |
| Hook Protocol          | 30      | 28     | -2 (1 warning)     |
| Agent Routing          | 25      | 21     | -4 (medium issues) |
| Progressive Disclosure | 20      | 13     | -7 (2 medium)      |
| **Total**              | **100** | **87** | **-13**            |

## Recommendations

1. **HIGH**: Add error patterns for ImportError, ConnectionError
2. **MEDIUM**: Add file patterns for _.yaml, _.yml
3. **LOW**: session-start.py error handling could be improved

Why This Approach

1. Reproducible - Scripts produce same results every time
2. Objective - JSON checklists remove interpretation
3. Fast - Automated checks run in seconds
4. Actionable - Specific file:line references
5. Versionable - Standards tracked in git
