## Overview
Complete Phase 2 core implementation for the portable Prompt Engineer Agent,
making prompt engineering accessible across .github control plane, WordPress
plugins, and WordPress theme contexts.
## Deliverables
**Skills (Analysis Framework)**
- analyze-prompt.skill.md: Systematic clarity analysis framework
* Completeness checks (goal, input, output, success criteria, errors, dependencies)
* Specificity analysis (concrete language, examples, edge cases)
* Constraint validation (scope, performance, resources, time)
* Context-specific rules (.github, WordPress plugin, WordPress theme)
* Scoring methodology: (Completeness + Specificity + Constraints) / 3
- improve-prompt.skill.md: Improvement suggestion engine
* Clarity improvements (vague → specific language)
* Completeness improvements (missing → provided context)
* Constraint improvements (implicit → explicit)
* Context-specific enhancement patterns
* Trade-off analysis for each suggestion
* Prioritization by impact/effort ratio
- validate-prompt.skill.md: Format and standards validation
* Format validation (structure, syntax, grammar)
* Context-specific rule validation
* Best practices compliance checking
* Schema validation for JSON/YAML examples
* Severity levels: error, warning, info
**Documentation**
- README.md: Quick start guide and feature overview
* Installation and basic usage
* Context detection explanation
* Architecture overview
* Phase roadmap and status
* Success criteria for Phase 2
- API.md: Complete API reference (1,000+ lines)
* Function signatures with TypeScript types
* Parameter specifications and return types
* 5+ working examples per function
* Usage patterns and workflow examples
* Error handling guidance
* Performance characteristics
- EXAMPLES.md: Real-world examples (800+ lines)
* GitHub workflow example (full refinement cycle)
* WordPress plugin example (hook validation)
* WordPress theme example (design tokens)
* Batch analysis workflow
* Iterative refinement demonstration
* Testing recommendations
**Configuration**
- package.json: NPM package configuration
* v1.0.0 initial version
* Scripts for testing and coverage
* Exports for individual skills
* Repository and author metadata
* Phase and context documentation
- index.js: Module entry point
* Placeholder implementations for Phase 3
* Context detection helper
* CLI interface for standalone use
* Clear phase status and next steps
**Tests (Specification)**
- tests/unit/analyze-prompt.test.md: Unit test specification
* 10+ completeness test cases
* 10+ specificity test cases
* 10+ constraint test cases
* 10+ context detection test cases
* 5+ score calculation test cases
* 5+ real prompt test cases
* Target: 80%+ coverage (Phase 3)

```
## Context Support
Three repository contexts with specialized rules:
**1. .github Control Plane**
- Workflow file path validation (.github/workflows/*)
- Trigger event specification (push, pull_request, schedule, manual)
- Label naming conventions (type:, status:, priority:, area:, meta:)
- Branch naming rules ({type}/{scope}-{title})
- GitHub App permission documentation
- Merge behavior and branch protection alignment
**2. WordPress Plugin**
- Hook type clarification (add_action vs. apply_filters)
- Hook naming conventions (plugin_prefix_function_name)
- Block registration syntax validation (block.json)
- Plugin version requirements (semantic versioning)
- Dependency documentation
- JavaScript enqueue best practices
**3. WordPress Theme**
- theme.json structure and validation
- Design token naming consistency
- WCAG AA color contrast requirements
- Template hierarchy compliance
- Pattern naming conventions
- CSS architecture specification
## Methodology
**Analysis Framework** (analyze-prompt.skill.md)
Evaluates clarity across three dimensions:
- Completeness: 0-10 based on necessary elements present
- Specificity: 0-10 based on concrete vs. vague language
- Constraints: 0-10 based on scope and limitation documentation
- Overall score: Average of three dimensions
**Improvement Engine** (improve-prompt.skill.md)
For each identified issue:
- States the problem with quoted phrase
- Explains why it matters
- Provides concrete before/after example
- Documents trade-offs (what you gain/lose)
- Estimates effort (low/medium/high)
- Assesses impact (high/medium/low)
- Prioritizes by impact/effort ratio
**Validation Framework** (validate-prompt.skill.md)
Three-tier validation:
- Format checks (syntax, structure, grammar)
- Context-specific rules (GitHub/plugin/theme conventions)
- Standards compliance (clarity, completeness, constraints)
Returns:
- Status: valid, invalid, or warning
- Score: 0-10 compliance rating
- Errors: Must-fix issues (blocking)
- Warnings: Should-fix issues (advisory)
- Recommendations: Optional improvements
## Success Criteria (Phase 2)
✅ **Completed:**
- Agent passes specification validation
- All three skills fully documented (1600+ lines)
- Context detection rules defined
- API documented with examples
- Real-world examples provided for each context
- Architecture designed for portability
- Package configuration prepared
⏳ **Phase 3 (Next):**
- Implement actual functions (not placeholders)
- Unit tests (80%+ coverage target)
- Integration tests (10+ per context)
- Multi-model validation (Sonnet/Haiku)
- Repository-specific testing

## Notes
This Phase 2 implementation provides complete specification and documentation
for the Prompt Engineer Agent. The skills serve as both specification documents
and can be used directly in Claude Code as prompts.
Phase 3 will implement the actual JavaScript functions with comprehensive
testing (80%+ coverage) and validation against real repository prompts.
Phase 4 will deliver NPM packaging and public distribution.
