ReAgent

> Reviews for your Agent

Why is this useful?

In the era of AI coding assistants, ensuring their output code is high quality is essential for maintaining a healthy codebase.

This often requires providing detailed, line-specific feedback, just like you would with a human teammate's code.

But pointing to specific lines through chat is clunky, and setting up GitHub PRs for local work-in-progress is really overkill.

ReAgent tackles that by creating a lightweight MCP server that opens a familiar, GitHub-style review interface right in your browser to speed your feedback cycles.

!ReAgent Usage

!Plan Review

Features

- Interactive browser-based code review UI
- Line-level comments with file tree navigation
- Approve or request changes workflow
- Git integration: review uncommitted changes, specific commits, or branch diffs
- Local file review: review arbitrary files

Usage

1. Add it as an MCP server to your favorite agentic coding tool.

``json
{
"mcpServers": {
"reagent": {
"command": "npx",
"args": [
"-y",
"@fsmiamoto/reagent@latest",
"mcp"
]
}
}
}
`

The recommended way to use ReAgent is to steer your agent whenever you want to create a review session.

`
> Let's plan a change to [...]. Write the plan as a markdown file on the plans/ directory and create a review session.
`

You can also add ReAgent instructions to your AGENTS.md (or any context file your agent loads) to enforce reviews automatically:

`
- You MUST create a review session using ReAgent and get approval before proceeding to implementation.
`

$3

ReAgent uses a two-step workflow to enable interactive browser-based code reviews:

1. create_review: Initiates a review session and returns a URL.
2. get_review: Retrieves the completed review results.

CLI Usage

ReAgent also provides a command-line interface for creating and managing review sessions.

For advanced users, you can also use the CLI directly without MCP by teaching your agent to invoke the commands (learn more).

$3

Install ReAgent globally to use the CLI:

`bash
npm install -g @fsmiamoto/reagent
`

Verify installation:

`bash
reagent --version
`

Alternatively, use npx without installation:

`bash
npx @fsmiamoto/reagent review
`

$3

The most common CLI workflow is creating a review of your code:

`bash


This will review all the uncommitted changes in your Git repo.


reagent review --auto-start
`

The --auto-start` flag automatically starts the server if it's not already running.

By default, the review URL will open in your browser.
