Overview

This public intake copy packages

plugins/antigravity-awesome-skills-claude/skills/tdd-workflows-tdd-refactor

https://github.com/sickn33/antigravity-awesome-skills

Use it when the operator needs the upstream workflow, support files, and repository context to stay intact while the public validator and private enhancer continue their normal downstream flow.

This intake keeps the copied upstream files intact and uses

metadata.json

ORIGIN.md

Imported source sections that did not map cleanly to the public headings are still preserved below or in the support files. Notable imported sections: Output Requirements, Safety Checklist, Recovery Protocol, Limitations.

When to Use This Skill

Use this section as the trigger filter. It should make the activation boundary explicit before the operator loads files, runs commands, or opens a pull request.

• Working on tdd workflows tdd refactor tasks or workflows
• Needing guidance, best practices, or checklists for tdd workflows tdd refactor
• The task is unrelated to tdd workflows tdd refactor
• You need a different domain or tool outside this scope
• Use when provenance needs to stay visible in the answer, PR, or review packet.
• Use when copied upstream references, examples, or scripts materially improve the answer.

Workflow

This workflow is intentionally editorial and operational at the same time. It keeps the imported source useful to the operator while still satisfying the public intake standards that feed the downstream enhancer flow.

1. Clarify goals, constraints, and required inputs.
2. Apply relevant best practices and validate outcomes.
3. Provide actionable steps and verification.
4. If detailed examples are required, open resources/implementation-playbook.md.
5. Run tests to establish green baseline
6. Analyze code smells and test coverage
7. Document current performance metrics

Refactor code with confidence using comprehensive test safety net:

[Extended thinking: This tool uses the tdd-orchestrator agent (opus model) for sophisticated refactoring while maintaining all tests green. It applies design patterns, improves code quality, and optimizes performance with the safety of comprehensive test coverage.]

Imported: Core Process

1. Pre-Assessment

• Run tests to establish green baseline
• Analyze code smells and test coverage
• Document current performance metrics
• Create incremental refactoring plan

2. Code Smell Detection

• Duplicated code → Extract methods/classes
• Long methods → Decompose into focused functions
• Large classes → Split responsibilities
• Long parameter lists → Parameter objects
• Feature Envy → Move methods to appropriate classes
• Primitive Obsession → Value objects
• Switch statements → Polymorphism
• Dead code → Remove

3. Design Patterns

• Apply Creational (Factory, Builder, Singleton)
• Apply Structural (Adapter, Facade, Decorator)
• Apply Behavioral (Strategy, Observer, Command)
• Apply Domain (Repository, Service, Value Objects)
• Use patterns only where they add clear value

4. SOLID Principles

• Single Responsibility: One reason to change
• Open/Closed: Open for extension, closed for modification
• Liskov Substitution: Subtypes substitutable
• Interface Segregation: Small, focused interfaces
• Dependency Inversion: Depend on abstractions

5. Refactoring Techniques

• Extract Method/Variable/Interface
• Inline unnecessary indirection
• Rename for clarity
• Move Method/Field to appropriate classes
• Replace Magic Numbers with constants
• Encapsulate fields
• Replace Conditional with Polymorphism
• Introduce Null Object

6. Performance Optimization

• Profile to identify bottlenecks
• Optimize algorithms and data structures
• Implement caching where beneficial
• Reduce database queries (N+1 elimination)
• Lazy loading and pagination
• Always measure before and after

7. Incremental Steps

• Make small, atomic changes
• Run tests after each modification
• Commit after each successful refactoring
• Keep refactoring separate from behavior changes
• Use scaffolding when needed

8. Architecture Evolution

• Layer separation and dependency management
• Module boundaries and interface definition
• Event-driven patterns for decoupling
• Database access pattern optimization

9. Safety Verification

• Run full test suite after each change
• Performance regression testing
• Mutation testing for test effectiveness
• Rollback plan for major changes

10. Advanced Patterns

• Strangler Fig: Gradual legacy replacement
• Branch by Abstraction: Large-scale changes
• Parallel Change: Expand-contract pattern
• Mikado Method: Dependency graph navigation

Imported: Output Requirements

• Refactored code with improvements applied
• Test results (all green)
• Before/after metrics comparison
• Applied refactoring techniques list
• Performance improvement measurements
• Remaining technical debt assessment

Examples

Example 1: Ask for the upstream workflow directly

Use @tdd-workflows-tdd-refactor to handle <task>. Start from the copied upstream workflow, load only the files that change the outcome, and keep provenance visible in the answer.

Explanation: This is the safest starting point when the operator needs the imported workflow, but not the entire repository.

Example 2: Ask for a provenance-grounded review

Review @tdd-workflows-tdd-refactor against metadata.json and ORIGIN.md, then explain which copied upstream files you would load first and why.

Explanation: Use this before review or troubleshooting when you need a precise, auditable explanation of origin and file selection.

Example 3: Narrow the copied support files before execution

Use @tdd-workflows-tdd-refactor for <task>. Load only the copied references, examples, or scripts that change the outcome, and name the files explicitly before proceeding.

Explanation: This keeps the skill aligned with progressive disclosure instead of loading the whole copied package by default.

Example 4: Build a reviewer packet

Review @tdd-workflows-tdd-refactor using the copied upstream files plus provenance, then summarize any gaps before merge.

Explanation: This is useful when the PR is waiting for human review and you want a repeatable audit packet.

Imported Usage Notes

Imported: Usage

Use Task tool with subagent_type="tdd-orchestrator" to perform safe refactoring.

Prompt: "Refactor this code while keeping all tests green: $ARGUMENTS. Apply TDD refactor phase:

Imported: Example: Extract Method Pattern

Before:

class OrderProcessor {
  processOrder(order: Order): ProcessResult {
    // Validation
    if (!order.customerId || order.items.length === 0) {
      return { success: false, error: "Invalid order" };
    }

    // Calculate totals
    let subtotal = 0;
    for (const item of order.items) {
      subtotal += item.price * item.quantity;
    }
    let total = subtotal + (subtotal * 0.08) + (subtotal > 100 ? 0 : 15);

    // Process payment...
    // Update inventory...
    // Send confirmation...
  }
}

After:

class OrderProcessor {
  async processOrder(order: Order): Promise<ProcessResult> {
    const validation = this.validateOrder(order);
    if (!validation.isValid) return ProcessResult.failure(validation.error);

    const orderTotal = OrderTotal.calculate(order);
    const inventoryCheck = await this.inventoryService.checkAvailability(order.items);
    if (!inventoryCheck.available) return ProcessResult.failure(inventoryCheck.reason);

    await this.paymentService.processPayment(order.paymentMethod, orderTotal.total);
    await this.inventoryService.reserveItems(order.items);
    await this.notificationService.sendOrderConfirmation(order, orderTotal);

    return ProcessResult.success(order.id, orderTotal.total);
  }

  private validateOrder(order: Order): ValidationResult {
    if (!order.customerId) return ValidationResult.invalid("Customer ID required");
    if (order.items.length === 0) return ValidationResult.invalid("Order must contain items");
    return ValidationResult.valid();
  }
}

Best Practices

Treat the generated public skill as a reviewable packaging layer around the upstream repository. The goal is to keep provenance explicit and load only the copied source material that materially improves execution.

• Keep the imported skill grounded in the upstream repository; do not invent steps that the source material cannot support.
• Prefer the smallest useful set of support files so the workflow stays auditable and fast to review.
• Keep provenance, source commit, and imported file paths visible in notes and PR descriptions.
• Point directly at the copied upstream files that justify the workflow instead of relying on generic review boilerplate.
• Treat generated examples as scaffolding; adapt them to the concrete task before execution.
• Route to a stronger native skill when architecture, debugging, design, or security concerns become dominant.

Troubleshooting

Problem: The operator skipped the imported context and answered too generically

Symptoms: The result ignores the upstream workflow in

plugins/antigravity-awesome-skills-claude/skills/tdd-workflows-tdd-refactor

metadata.json

ORIGIN.md

Problem: The imported workflow feels incomplete during review

Symptoms: Reviewers can see the generated

SKILL.md

Problem: The task drifted into a different specialization

Symptoms: The imported skill starts in the right place, but the work turns into debugging, architecture, design, security, or release orchestration that a native skill handles better. Solution: Use the related skills section to hand off deliberately. Keep the imported provenance visible so the next skill inherits the right context instead of starting blind.
