Code Review Checklist

Code Review Checklist

Overview

This public intake copy packages plugins/antigravity-awesome-skills-claude/skills/code-review-checklist from https://github.com/sickn33/antigravity-awesome-skills into the native Omni Skills editorial shape without hiding its origin.

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 the external_source block in metadata.json plus ORIGIN.md as the provenance anchor for review.

Code Review Checklist

Imported source sections that did not map cleanly to the public headings are still preserved below or in the support files. Notable imported sections: How It Works, Functionality Review, Security Review, Code Quality Review, Complete Review Checklist, Common Pitfalls.

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.

• Use when reviewing pull requests
• Use when conducting code audits
• Use when establishing code review standards for a team
• Use when training new developers on code review practices
• Use when you want to ensure nothing is missed in reviews
• Use when creating code review documentation

Operating Table

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. Confirm the user goal, the scope of the imported workflow, and whether this skill is still the right router for the task.
2. Read the overview and provenance files before loading any copied upstream support files.
3. Load only the references, examples, prompts, or scripts that materially change the outcome for the current request.
4. Execute the upstream workflow while keeping provenance and source boundaries explicit in the working notes.
5. Validate the result against the upstream expectations and the evidence you can point to in the copied files.
6. Escalate or hand off to a related skill when the work moves out of this imported workflow's center of gravity.
7. Before merge or closure, record what was used, what changed, and what the reviewer still needs to verify.

Imported Workflow Notes

Imported: Overview

Provide a systematic checklist for conducting thorough code reviews. This skill helps reviewers ensure code quality, catch bugs, identify security issues, and maintain consistency across the codebase.

Imported: How It Works

Step 1: Understand the Context

Before reviewing code, I'll help you understand:

• What problem does this code solve?
• What are the requirements?
• What files were changed and why?
• Are there related issues or tickets?
• What's the testing strategy?

Step 2: Review Functionality

Check if the code works correctly:

• Does it solve the stated problem?
• Are edge cases handled?
• Is error handling appropriate?
• Are there any logical errors?
• Does it match the requirements?

Step 3: Review Code Quality

Assess code maintainability:

• Is the code readable and clear?
• Are names descriptive?
• Is it properly structured?
• Are functions/methods focused?
• Is there unnecessary complexity?

Step 4: Review Security

Check for security issues:

• Are inputs validated?
• Is sensitive data protected?
• Are there SQL injection risks?
• Is authentication/authorization correct?
• Are dependencies secure?

Step 5: Review Performance

Look for performance issues:

• Are there unnecessary loops?
• Is database access optimized?
• Are there memory leaks?
• Is caching used appropriately?
• Are there N+1 query problems?

Step 6: Review Tests

Verify test coverage:

• Are there tests for new code?
• Do tests cover edge cases?
• Are tests meaningful?
• Do all tests pass?
• Is test coverage adequate?

Examples

Example 1: Ask for the upstream workflow directly

Use @code-review-checklist 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 @code-review-checklist 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 @code-review-checklist 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 @code-review-checklist 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.

## 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.

- Review Small Changes - Smaller PRs are easier to review thoroughly
- Check Tests First - Verify tests pass and cover new code
- Run the Code - Test it locally when possible
- Ask Questions - Don't assume, ask for clarification
- Be Constructive - Suggest improvements, don't just criticize
- Focus on Important Issues - Don't nitpick minor style issues
- Use Automated Tools - Linters, formatters, security scanners

### Imported Operating Notes

#### Imported: Best Practices

### ✅ Do This

- **Review Small Changes** - Smaller PRs are easier to review thoroughly
- **Check Tests First** - Verify tests pass and cover new code
- **Run the Code** - Test it locally when possible
- **Ask Questions** - Don't assume, ask for clarification
- **Be Constructive** - Suggest improvements, don't just criticize
- **Focus on Important Issues** - Don't nitpick minor style issues
- **Use Automated Tools** - Linters, formatters, security scanners
- **Review Documentation** - Check if docs are updated
- **Consider Performance** - Think about scale and efficiency

### ❌ Don't Do This

- **Don't Approve Without Reading** - Actually review the code
- **Don't Be Vague** - Provide specific feedback with examples
- **Don't Ignore Security** - Security issues are critical
- **Don't Skip Tests** - Untested code will cause problems
- **Don't Be Rude** - Be respectful and professional
- **Don't Rubber Stamp** - Every review should add value
- **Don't Review When Tired** - You'll miss important issues
- **Don't Forget Context** - Understand the bigger picture

## 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/code-review-checklist`, fails to mention provenance, or does not use any copied source files at all.
**Solution:** Re-open `metadata.json`, `ORIGIN.md`, and the most relevant copied upstream files. Check the `external_source` block first, then restate the provenance before continuing.

### Problem: The imported workflow feels incomplete during review

**Symptoms:** Reviewers can see the generated `SKILL.md`, but they cannot quickly tell which references, examples, or scripts matter for the current task.
**Solution:** Point at the exact copied references, examples, scripts, or assets that justify the path you took. If the gap is still real, record it in the PR instead of hiding it.

### 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.

function processOrder(order) {
  // Validate order
  if (!order.items) throw new Error('No items');

  // Calculate total
  let total = 0;
  for (let item of order.items) {
    total += item.price * item.quantity;
  }

  // Apply discount
  if (order.coupon) {
    total *= 0.9;
  }

  // Process payment
  const payment = stripe.charge(total);

  // Send email
  sendEmail(order.email, 'Order confirmed');

  // Update inventory
  updateInventory(order.items);

  return { orderId: order.id, total };
}
\`\`\`

**✅ Good - Separated concerns:**
