What Code Reviewer by boshu2 is

Code Reviewer by boshu2 is a subagent published in the boshu2/agentops repository on GitHub, which has about 446 stars. The repository describes itself as: “DevOps discipline for AI coding agents: shape the work, track it as a graph, and get each change judged by a context that didn't write it.”

A subagent is a specialist assistant that Claude can hand part of a task to. It is a markdown file whose frontmatter sets a name, a description that tells Claude when to delegate, and optionally the tools and model it may use; the body becomes the subagent's own system prompt.

Because a subagent works in its own context, it keeps the main conversation focused: Claude can send a narrow job, such as a review or a specialised analysis, to Code Reviewer and get back a compact result.

It is set up to use these tools: Read, Grep, Glob, Bash. Limiting tools is a good sign: the subagent can only do what those tools allow.

How to install Code Reviewer by boshu2

Claude Code

Download code-reviewer.md from the repository.
Save it to ~/.claude/agents/ to use it in every project, or to .claude/agents/ inside one project to share it through version control.
Claude Code watches these folders, so the subagent is usually available right away. Ask Claude to use it by name, or @-mention it to make sure it runs.

Claude Cowork

Cowork loads subagents through plugins. If the repository is packaged as a plugin marketplace, add it under Customize → Plugins → Add marketplace and install the plugin that contains this subagent.
Otherwise, bundle the file into your own plugin's agents/ folder and upload it from Customize → Plugins.

Focus on modified files
Review for quality, security, and maintainability

Provide feedback organized by priority:

Critical (must fix): Security vulnerabilities, data loss risks, broken functionality
Warning (should fix): Performance issues, error handling gaps, test coverage
Suggestion (consider): Readability improvements, naming conventions, documentation

Include specific code references and examples of how to fix issues.

Before you install

Read the whole file first. Skills, commands, and subagents are instructions Claude will follow, so make sure they match what you want.
Check which tools, scripts, or MCP servers it uses. Local servers and scripts run with your permissions.
Try it in a test project or a copy of your files before pointing it at real work.
Pin the version you tested, and review changes before updating.
Watch for instructions that fetch web content or run shell commands; those are where prompt injection risks start. See our prompt injection guide.
