SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) components.

What problem does it solve? Getting a genuine second opinion on a code change is hard when the only available reviewer is the same model that wrote the code. This Skill runs a model from a different provider against your repository in read-only mode, so findings come from an independent reviewer that cannot modify your files. ## Core Features & Use Cases - Cross-Provider Read-Only Review: Runs OpenAI (codex), Anthropic (claude), and Google (agy) CLIs against a repository with write access removed, returning the review plus the model that produced it. - Provider Readiness Check: The check subcommand probes each provider with a known file to verify it can actually read the repository before you spend a review. - Honest Failure Reporting: A reviewer that was locked out, denied permissions, or returned nothing is reported as a failure with exit codes and remediation hints, never as "no findings". - Use Case: Before merging a non-trivial change, write a short prompt naming the change and paths, run the Google or Anthropic reviewer, then record in the pull request which findings were acted on, declined, or reproduced. ## Quick Start Ask the agent to have a model from another provider review this change using the model-review skill, then weigh and record the findings.

FAQPage Schema
How do I get a second opinion on a code change from another AI model?

Write a prompt file naming the change, the paths to read, and its purpose, then run the review script with a provider flag such as --provider google. The reviewer reads the repository with its own tools in read-only mode and returns findings as JSON.

Which AI providers can review my repository read-only?

Three providers are supported: OpenAI via the codex CLI, Anthropic via the claude CLI, and Google via the agy CLI. Each is launched so it can read the repository but has no way to write to it.

How do I check if a provider CLI can read my repository before running a review?

Run the check subcommand with --repo pointing at your repository. It probes each provider with a known file and reports which are ready, not installed, or unable to read, so you do not waste a review on a locked-out reviewer.

Why does the Google agy reviewer fail with denied actions?

Headless agy stops at the first tool needing permission, so it needs read-only allow rules in your settings.json. The failure includes a hint with the exact rules to add, and the configure subcommand can apply them only when you explicitly ask.

When should I not use cross-provider model review?

Do not use it for ordinary review of tested code, a human reviewer's comments, or type-checker and scanner output. It is meant for changes where an independent outside opinion adds signal, not routine verification.
