SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Self-review by a single AI assistant cannot catch its own blind spots, and asking the same vendor's model again produces the same biases. This Skill gets a genuine second opinion by routing your document, plan, or decision to AI assistants from other vendors installed on the machine, then synthesizing where they agree, where they disagree, and which position is better supported. ## Core Features & Use Cases - Cross-Vendor Peer Review: Discovers installed assistant CLIs (Antigravity, Claude Code, Codex), lets the user pick which peers to convene, and relays their verbatim responses. - Structured Synthesis: Reports convergence, disagreements, errors caught by peers, and unresolved issues, with the host adjudicating splits by reasoned argument rather than majority vote. - CLI Trap Avoidance: Documents per-CLI invocation pitfalls (argument ordering, stdin vs argument prompts, permission flags, session resume) so reviews do not silently answer the wrong question. - Use Case: Before committing to an architecture decision, ask the assistant to run it past Codex and Claude; receive both critiques verbatim plus a synthesis of what the host's own analysis missed. ## Quick Start Ask the assistant to run this plan past the other AI assistants installed on this machine and report where they disagree.

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

Ask the assistant to run the document past the other AI assistants installed on your machine. The skill discovers available peer CLIs, lets you choose which to convene, sends the brief, and reports verbatim responses plus a synthesis of agreement and disagreement.

Which AI assistants can participate in a cross-vendor review?

Any installed assistant CLI with a headless mode can participate: Antigravity (agy), Claude Code (claude), and Codex (codex). The skill probes which are installed at runtime and never assumes a fixed roster or hard-pinned model names.

Does cross-vendor review cost money or send data externally?

Yes. Each peer round is a paid API call billed to your account with that vendor, and anything sent to a peer leaves your machine. The skill states this before the first payload and asks you to choose which peers to convene.

When should I not use cross-vendor peer review?

Avoid it for factual lookups or problems with one right answer, since the value is disagreement between vendors. Also skip it if your platform cannot shell out to other processes, or if the material must not be sent to certain vendors.

Why does the skill forbid impersonating other AI models?

One model role-playing another vendor manufactures the appearance of independence without real independent scrutiny, which is worse than no review. If peers cannot be reached via their CLIs, the skill says so plainly instead of simulating them.
