description	Multi-agent deep review of a GitLab merge request. Use when given an MR URL or ID to review thoroughly; findings are consolidated and never posted to the MR.

When invoked with a Merge Request URL or ID, execute the following autonomous workflow:

1. Fetch the MR diff, description, and related context.
2. Create an agent team to explore the MR from different angles. Spawn 5 teammates to review the code:
   • Security Reviewer: Scan for vulnerabilities and unsafe data handling.
   • Performance Reviewer: Identify performance bottlenecks. You MUST require benchmark verification and provide measured variance for any performance claims.
   • Test Coverage Reviewer: Propose concrete testing scenarios strictly modeled on existing specs (e.g., RSpec/Playwright) in this repository.
   • Pattern Conformance Reviewer: Search the codebase. You MUST provide grep evidence that a recommended pattern already exists in other places before suggesting it to the user.
   • Regression Risk Reviewer: Analyze recent squash commits and git blame for related changes that might conflict.
3. Run a Critic Agent teammate to play devil's advocate -- evaluate all subagent findings. The Critic MUST reject and filter out any finding that lacks a specific file:line citation, lacks measured evidence, or constitutes generic best-practice advice not grounded in this codebase.
4. Output a single consolidated review containing:
   • Blocking issues, architectural concerns, and minor nits (in that order).
   • Explicit confidence levels (HIGH/MED/LOW) for every claim.
   • Exact file:line citations for all feedback.
   • DO NOT post any comments to the Merge Request.
