• Agent: bill-billing-unit-test-reviewer
• Skill: /review-test - Unit test code review
• Expertise: TDD, test design, coverage analysis, avoiding over-engineering

2. bill-code-reviewer

Code quality review and PR Review

• Agent: bill-code-reviewer (preloads effective-java, clean-architecture skills)
• Skills:
  • /code-review - Code quality review (Clean Code + avoiding over-engineering)
  • /review-pr - PR change review (branch diff or GitHub PR, runs in forked context)
• Expertise: Clean Code, avoiding over-engineering, architecture evaluation, PR Review

3. bill-java-developer

Spring Boot development and database optimization expert

• Agent: bill-java-developer (preloads effective-java, clean-architecture, mysql-optimization skills)
• Skills:
  • /design-solution - Technical solution design and recommendations
  • /optimize-query - SQL/JPA optimization (runs in forked context)
• Expertise: Spring Boot, JPA, database performance, enterprise architecture

4. bill-java-skills

Java development best practices knowledge base

• Skills (preloaded by agents, not shown in / menu):
  • clean-architecture - Clean Architecture design principles
  • effective-java - Effective Java best practices
  • mysql-optimization - MySQL performance optimization and JPA tuning

Difference between Skills and Agents:

• Skills (/xxx): Slash commands or auto-triggered knowledge base
• Agents: Automatically start based on conversation, provide interactive assistance

Agent Advanced Features

• Knowledge Preloading: bill-java-developer and bill-code-reviewer agents automatically preload relevant knowledge skills (effective-java, clean-architecture, mysql-optimization) — no manual invocation needed
• Project Memory: All agents support project-level memory, remembering project-specific patterns and conventions across sessions
• Safety Restrictions: Reviewer agents have read-only permissions and will not accidentally modify code
• Gotchas Protection: Every skill includes a curated Gotchas section — common pitfalls that Claude tends to fall into, ensuring higher quality output

Installation

Option 1: Via /plugin marketplace (recommended, no clone needed)

In Claude Code, run:

/plugin marketplace add xinqilin/claude-dev-toolkit-marketplace

Option 2: Via install.sh (after cloning, uses symlinks — auto-updates on git pull)

git clone https://github.com/xinqilin/claude-dev-toolkit-marketplace
cd claude-dev-toolkit-marketplace
./install.sh --all

Quick Start

Using Slash Commands

Code Review

/code-review src/main/java/com/example/OrderService.java

PR Review

# Review GitHub PR (requires gh CLI)
/review-pr 123
/review-pr #456

# Review current branch diff against master
/review-pr

# Review feature-branch against develop
/review-pr feature-branch develop

Note: GitHub PR review requires gh CLI:

brew install gh
gh auth login

Spring Boot Development

/design-solution
[Describe your requirements or problem]

/optimize-query
[Paste your SQL or JPA code]

Tip: mysql-optimization knowledge is automatically preloaded into the bill-java-developer agent.

Unit Test Review

/review-test src/test/java/com/example/OrderServiceTest.java

Using Agents

Agents automatically activate based on conversation context:

• Java Developer Agent: "I need to design a high-concurrency order system"
• Code Reviewer Agent: "Please review this code's quality"
• Unit Test Reviewer Agent: "Please review my unit test design"

Auto-Triggered Skills (bill-java-skills)

Knowledge skills (clean-architecture, effective-java, mysql-optimization) are preloaded into agents automatically — see Agent Advanced Features above.
