Pr Review Toolkit by ccplugins

A comprehensive collection of specialized agents for thorough pull request review, covering code comments, test coverage, error handling, type design, code quality, and code simplification.

Overview

This plugin bundles 6 expert review agents that each focus on a specific aspect of code quality. Use them individually for targeted reviews or together for comprehensive PR analysis.

Agents

1. comment-analyzer

Focus: Code comment accuracy and maintainability

Analyzes:

• Comment accuracy vs actual code
• Documentation completeness
• Comment rot and technical debt
• Misleading or outdated comments

When to use:

• After adding documentation
• Before finalizing PRs with comment changes
• When reviewing existing comments

Triggers:

"Check if the comments are accurate"
"Review the documentation I added"
"Analyze comments for technical debt"

2. pr-test-analyzer

Focus: Test coverage quality and completeness

Analyzes:

• Behavioral vs line coverage
• Critical gaps in test coverage
• Test quality and resilience
• Edge cases and error conditions

When to use:

• After creating a PR
• When adding new functionality
• To verify test thoroughness

Triggers:

"Check if the tests are thorough"
"Review test coverage for this PR"
"Are there any critical test gaps?"

3. silent-failure-hunter

Focus: Error handling and silent failures

Analyzes:

• Silent failures in catch blocks
• Inadequate error handling
• Inappropriate fallback behavior
• Missing error logging

When to use:

• After implementing error handling
• When reviewing try/catch blocks
• Before finalizing PRs with error handling

Triggers:

"Review the error handling"
"Check for silent failures"
"Analyze catch blocks in this PR"

4. type-design-analyzer

Focus: Type design quality and invariants

Analyzes:

• Type encapsulation (rated 1-10)
• Invariant expression (rated 1-10)
• Type usefulness (rated 1-10)
• Invariant enforcement (rated 1-10)

When to use:

• When introducing new types
• During PR creation with data models
• When refactoring type designs

Triggers:

"Review the UserAccount type design"
"Analyze type design in this PR"
"Check if this type has strong invariants"

5. code-reviewer

Focus: General code review for project guidelines

Analyzes:

• CLAUDE.md compliance
• Style violations
• Bug detection
• Code quality issues

When to use:

• After writing or modifying code
• Before committing changes
• Before creating pull requests

Triggers:

"Review my recent changes"
"Check if everything looks good"
"Review this code before I commit"

6. code-simplifier

Focus: Code simplification and refactoring

Analyzes:

• Code clarity and readability
• Unnecessary complexity and nesting
• Redundant code and abstractions
• Consistency with project standards
• Overly compact or clever code

When to use:

• After writing or modifying code
• After passing code review
• When code works but feels complex

Triggers:

"Simplify this code"
"Make this clearer"
"Refine this implementation"

Note: This agent preserves functionality while improving code structure and maintainability.

Usage Patterns

Individual Agent Usage

Simply ask questions that match an agent's focus area, and Claude will automatically trigger the appropriate agent:

"Can you check if the tests cover all edge cases?"
→ Triggers pr-test-analyzer

"Review the error handling in the API client"
→ Triggers silent-failure-hunter

"I've added documentation - is it accurate?"
→ Triggers comment-analyzer

Comprehensive PR Review

For thorough PR review, ask for multiple aspects:

"I'm ready to create this PR. Please:
1. Review test coverage
2. Check for silent failures
3. Verify code comments are accurate
4. Review any new types
5. General code review"

This will trigger all relevant agents to analyze different aspects of your PR.
