Could you build this?

Partial The AI code review bot interface is standard, but the rust-based Git extension tracking per-line LLM provenance along with isolated PR sandboxing requires low-level git hacking.

What it would actually take: Requires a Rust CLI extension wrapping `git` or `libgit2` to parse commit metadata and track authorship at the hunk/line level, alongside a serverless microVM orchestrator (like Firecracker) to securely spin up sandboxes, run untrusted pull request code, and evaluate test suites.

Discussion

5 comments analyzed.

Competitors mentioned: git trailers, git notes

Concerns raised: Agents could lie about what they wrote (trust/verification gap), Trailers wouldn't provide granularity needed, Agents could be overridden by passing prompts to Codex/Claude Code defaults

Feature requests: Speed comparable to git notes, Deeper granularity than trailers allow
