Code Review

Overview#

Agentastic includes integrated code review powered by AI agents. Review your changes before committing or get suggestions on existing code. Multiple agents can run in parallel, each providing a different perspective.

Using Code Review#

Review Current Changes#

1. Click the Code Review button in the toolbar
2. Select which agent(s) to use (or use your defaults from Settings)
3. The agent runs in a new terminal tab
4. Review the feedback in the terminal output

From the Toolbar#

• Click - Run review with enabled agents from Settings
• Hold/Menu - Select specific agent(s) to use

What Gets Reviewed#

The review prompt includes:

• Current branch vs target branch comparison
• Complete unified diff of all changes
• Commit history between branches
• Review criteria prioritization

Review Criteria#

Agents are prompted to prioritize:

1. Bugs - Logic errors, edge cases, null handling
2. Security - Vulnerabilities, input validation, secrets
3. Performance - Inefficiencies, memory leaks, N+1 queries
4. Maintainability - Code clarity, documentation, patterns
5. Testing - Test coverage, test quality

Multi-Agent Reviews#

Enable multiple agents to get diverse perspectives:

1. Go to Settings > Code Review
2. Enable the agents you want to use
3. Click Review - all enabled agents run in parallel
4. Each agent opens in its own terminal tab

Different agents catch different issues:

• Claude excels at understanding intent and architecture
• Codex focuses on code patterns and best practices
• CodeRabbit specializes in PR-specific feedback
• Greptile reviews the branch diff with full-codebase context

Adding Custom Agents#

Add your own review agents to integrate team tools or alternative AI services.

Configuration#

1. Go to Settings > Code Review
2. Scroll to Custom Agents
3. Click Add Agent
4. Enter:
   • Name: Display name for the agent
   • Command: Shell command to execute

Command Template#

Use {prompt} as a placeholder for the review prompt:

If {prompt} is not in your command, the prompt is passed via a temporary file:

Examples#

Local LLM with Ollama:

Custom script:

Team review tool:

Configuration#

Access code review settings in Settings > Code Review:

Setting	Description

Review Workflow#

A typical review workflow:

1. Make your code changes
2. View changes in the Diff Viewer
3. Click Review to get AI feedback
4. Address suggestions
5. Commit when satisfied

Tips#

• Review smaller changes for more focused feedback
• Use multiple agents for diverse perspectives
• Custom agents can integrate with your team's tools
