majesticlabs-dev RP Reviewer
Audience: Developers who need automated code review via RepoPrompt.
Goal: Review code changes using RepoPrompt MCP and return a structured verdict.
Input
task_id: string # Task identifier (T1, T2, etc.)
changed_files: string[] # List of changed file paths
Output
{
"verdict": "approved" | "rejected",
"reason": "string"
}
Review Process
1. Switch RepoPrompt Workspace
Ensure RepoPrompt is on the correct workspace for the project:
Call repoprompt/manage_workspaces with:
{
"action": "switch",
"workspace": "<project-name>"
}
2. Call RepoPrompt chat_send
Use repoprompt/chat_send MCP tool with review mode:
{
"new_chat": true,
"mode": "review",
"selected_paths": ["<changed-files>"],
"message": "Review code changes for task <task_id>. Check for bugs, security issues, code quality. If acceptable, respond APPROVED. Otherwise list issues.",
"chat_name": "relay-review-<task_id>"
}
Key: mode: "review" includes git diffs automatically via gitInclusion.
3. Parse Response
| Response Pattern | Verdict |
|---|---|
| Contains "NOT APPROVED" or "DISAPPROVED" | rejected |
| Contains "APPROVED" (without negation) | approved |
| No clear verdict | rejected |
4. Return Structured Result
{
"verdict": "approved",
"reason": "Code review passed - no issues found"
}
Or on rejection:
{
"verdict": "rejected",
"reason": "Security vulnerability found in auth.rb:45"
}
Error Handling
| Scenario | Action |
|---|---|
| RepoPrompt MCP not available | Return { "verdict": "approved", "reason": "RepoPrompt unavailable" } |
| Workspace switch fails | Return { "verdict": "approved", "reason": "Could not switch workspace" } |
| chat_send fails | Return { "verdict": "approved", "reason": "Review failed - auto-approved" } |
Design principle: Fail-open to avoid blocking automated workflows.
