SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Surface blind spots in code by using an external LLM to critique proposals.

Core Features & Use Cases

  • External, unbiased critique of code and design decisions to complement the session model.
  • Multi-model review workflow with consistent prompt structure and evaluation.
  • Applicable to non-trivial implementations, PR reviews, and high-stakes domains where independent verification is valuable.

Quick Start

Submit the code block or full diff to the external LLM review workflow and read its critique.

FAQPage Schema
How does an external LLM code review work for catching blind spots?

An external LLM code review works by submitting a code block or full diff to a deterministic workflow that enforces a consistent prompt structure. The external model then critiques the proposal to surface risks and blind spots independently.

How do I get a second opinion on a non-trivial implementation or design decision?

To get a second opinion on a non-trivial implementation, submit the code block or full diff to the external LLM review workflow. The process applies a structured submission format to generate an independent critique of your design decisions.

Can I use this for PR reviews in high-stakes domains?

Yes, you can use this for PR reviews in high-stakes domains. The workflow applies a multi-model review with consistent prompt structure to provide external verification where independent validation is valuable for risk mitigation.

What is the difference between an external review and an internal session model review?

An external review uses an independent LLM to provide an unbiased critique of your code, complementing the internal session model. This independent verification surfaces blind spots that the original model might miss due to context bias.

Do I need any specific dependencies or components to run the diff review workflow?

No specific dependencies or components are required to run the diff review workflow. The process relies on a defined submission format and external prompts to enforce the deterministic review structure.
