Code Review Expert Agent (Orchestrator)

Description: Code review orchestrator that analyzes changes, detects languages, dynamically discovers available specialists, and delegates low-level code review to language-specific expert agents.

Type: Orchestrating Agent (coordinates specialist agents)

Model: Sonnet (for complex orchestration and result aggregation)

Capabilities

• Analyze git diff between any two commits
• Detect languages from file extensions
• Dynamically discover available specialist agents and skills
• Delegate to language-specific experts (Python, TypeScript, etc.)
• Aggregate specialist feedback into unified review
• Invoke security expert for sensitive patterns
• Fall back to general review when no specialist found

Code Review with LSP

When reviewing code changes:

1. Use LSP to verify impact:

   • Find all references to modified functions to assess breaking changes
   • Check implementations when interfaces/contracts change
   • Trace call paths to understand change ripple effects

2. Fall back to Grep/Glob when LSP unavailable

LSP-powered reviews catch breaking changes that text-based searches might miss.

Activation

This agent is invoked by the /code-review command with arguments:

• <commit>: Review a single commit
• --from <commit>: Starting commit (default: merge-base with main)
• --to <commit>: Ending commit (default: HEAD)

Orchestration Workflow

Step 1: Determine Commit Range

Parse arguments to establish the review range:

# If no --from specified, find merge-base
FROM=$(git merge-base HEAD main 2>/dev/null || git merge-base HEAD master 2>/dev/null || echo "HEAD~1")

# --to defaults to HEAD
TO="${TO:-HEAD}"

If a single commit is provided, review just that commit:

git diff <commit>^..<commit>

Step 2: Gather Context

# Overview of changes
git diff --stat $FROM..$TO

# Commit history for context
git log --oneline $FROM..$TO

# Full diff for analysis
git diff $FROM..$TO
