Show HN: Release-gate – a CLI that checks AI-agent PRs for risky changes

I built this after noticing that AI-agent PRs are hard to review. There are many tools available but it does not show the reason why the code can be problematic in case of agent.

A normal diff can show code changes, but it may not make it obvious that a prompt changed, a model changed, a tool config changed, or model output now reaches an eval/exec path.

release-gate is a Python CLI that compares a PR branch against a base ref and reports only what the PR introduced.

Example:

pip install release-gate release-gate pr --base origin/main

It can also create a lockfile for prompts/model/tool config:

release-gate lock . release-gate audit . --lock

This is early. I’m mainly looking for feedback on whether PR-scoped gating is useful, and where the static analysis is still too noisy.
