Code Review via Cubic CLI

Run AI-powered code reviews using Cubic CLI to detect bugs, security vulnerabilities, and style issues in local changes. Use when the user says "review my code," "check my changes for bugs," "run cubic review," "review this diff," "pre-commit check," "find issues before I push," "analyze my branch changes," or "code quality check." Triggers on mentions of cubic, code review, diff review, pre-commit checks, bug detection, and code quality validation.

Cubic CLI - AI Code Review

Detect bugs, security issues, and code quality problems in local changes by running cubic review via Bash.

When to Use

User asks to review code changes, diffs, or branches
Pre-commit quality checks or bug detection
Security vulnerability scanning on changed files
Code style and best practice validation
Comparing branch changes before creating a PR

Prerequisites

Cubic CLI must be installed. If cubic is not found in PATH, inform the user with installation options:

curl -fsSL https://cubic.dev/install | bash
npm install -g @cubic-dev-ai/cli

Do not run the installation command automatically. Let the user decide.

If cubic returns an authentication error, inform the user to run cubic login or complete browser-based authentication.

CLI Quick Reference

Always pass --json for structured output. Key modes:

cubic review --json -- review uncommitted changes (default)
cubic review --base main --json -- compare against a branch (PR-style)
cubic review --commit HEAD~1 --json -- review a specific commit
cubic review --prompt "focus area" --json -- custom review focus

Constraint: --base, --commit, and --prompt are mutually exclusive.

JSON Output Format

{
  "issues": [
    {
      "priority": "P0",
      "file": "src/api/auth.ts",
      "line": 45,
      "title": "SQL injection vulnerability in user lookup",
      "description": "User input is concatenated directly into SQL query without parameterization."
    }
  ]
}

Priority levels: P0 (critical) > P1 (high) > P2 (medium) > P3 (low).

Workflow

Run cubic review --json (or with --base/--commit as appropriate)
Parse the JSON output to identify issues
Sort issues by priority (P0 first)
For each issue, read the referenced file and line
Present proposed fixes to the user for approval before applying
Apply approved fixes using Edit tool
Re-run cubic review --json to verify fixes

For the full command reference and step-by-step workflow, use /cubic:review.
