insane-review
GPT Pro (the Pro reasoning tier of the current flagship — currently GPT-5.6 Sol) has no API. This plugin uses it from inside Claude Code anyway.

GPT Pro lives only in the ChatGPT web app (subscription) — there is no official API, so you can't reach it from Codex CLI, omc ask, or an agent-council API provider. insane-review drives your logged-in ChatGPT web session over CDP: it packs the relevant code with repomix, sends it to Pro, and harvests the review. Zero API cost — it runs on your existing ChatGPT plan.

Quick Start

1. Add the marketplace (once)

5. Run it

Or just say "have Pro review this" / "ask GPT Pro about this design" — Claude figures out the target and packs it.

Why insane-review?

- The only way to reach Pro programmatically — no API exists. A logged-in web session driven over CDP is the bridge, and it costs nothing beyond your subscription.
- Claude picks the complete relevant set — you don't have to hand-list files. For reviews it sends full code (no --compress, which strips function bodies and produces false "looks fine" verdicts) and audits the packed file list so nothing is silently missing.
- fail-closed by design — wrong model, unverified login, truncated prompt, an empty pack, or a previous turn's answer are all refused rather than silently sent or saved. Hardened across four rounds of Pro's own self-review (6 → 0 P0s).
- Two roles, one engine — a standalone reviewer when you ask for a fix/review, or…
