PR bot enters the group chat
Show HN: How to build and self-host a code review agent
Build your own robot PR reviewer in minutes—and the crowd already wants upgrades
TLDR: A developer says they’ve made it quick to build your own AI helper that reviews code changes and comments on pull requests. The early community mood is classic hacker feedback: impressed, but already pushing extra tools and upgrades before they’ll call it truly done.
A developer rolled into Show HN with a bold promise: you can build and host your own AI code review helper in under five minutes. The pitch is simple even if the plumbing underneath is not: tag the bot in a GitHub pull request, let it safely inspect the code, and have it post feedback back to the team. The creator says the whole point of Tilde is to make these kinds of work-bots easier to assemble, manage, and deploy without handing over the keys to your kingdom.
But in true internet fashion, the real action wasn’t just the demo—it was the instant backseat-driving from the community. The first reaction out of the gate was basically, “Cool, but have you tried this other thing?” One commenter jumped in with a classic hacker-world remix note, pointing to another tool called Reticle to double-check the agent’s coding work and suggesting it could make the setup “even more better.” That tiny phrase has big comment-section energy: part helpful suggestion, part sly critique, part open invitation to keep optimizing forever.
And honestly, that’s the vibe hanging over the whole post: admiration mixed with the eternal developer curse of nothing is ever truly finished. The creator even admits spending ages stuck in “just one more feature” mode before finally declaring it ready. So the crowd response feels very on-brand—less “wow, ship it” and more “nice, now bolt on three more layers and let’s see what happens.” It’s less a launch and more the opening bell in the comments’ favorite sport: enthusiastic nitpicking.
Key Points
- •The article introduces Tilde as a cloud-based harness SDK for building AI agents and says it was created to improve portability, composability, and developer experience.
- •Tilde’s core platform components are Tools, ChatKit, and Memory, which together provide integrations, communications, and persistent knowledge for agents.
- •The post uses a code review agent as a practical example, with requirements including GitHub PR triggering, secure sandboxed code checkout, protected credentials, diff analysis, and PR commenting.
- •A deployable example of the code review bot is provided in Tilde’s GitHub repository, and the article says the SDK handles most of the surrounding infrastructure.
- •The article says users can import a tilde-state.yaml file into a Tilde account to set up infrastructure and integrations, then configure GitHub and Modal sandbox settings.
