Domain-Specific Review Personalities

[lovestaco]

Code review requirements vary dramatically between domains. An embedded systems developer working on ESP32 firmware is looking for completely different feedback than a developer building a MERN application or a Kubernetes operator.

What if AI code reviewers could adopt domain-specific personalities?

For example, an Embedded Systems personality could focus on memory leaks, resource management, ISR safety, pin configurations, concurrency issues, and hardware constraints. A MERN personality could prioritize API design, authentication, database interactions, scalability, and frontend performance.

Rather than applying the same review criteria to every project, the reviewer could tailor its feedback to the domain, language, and runtime environment.

Would domain-specific review personalities improve the usefulness of AI code reviews?

Hey Shrijith and the Hexmos team! Thanks for opening up this discussion.

I think introducing "Domain-Specific Personalities" is exactly what will take git-lrc from a general AI helper to an essential, production-grade build tool. Because I spend a lot of time bridging the gap between embedded IoT hardware and cloud backends, I run into very different sets of problems depending on the repository I am working in.

Here are two specific "personalities" and the exact edge-cases they should look for during a commit:

1. The "Embedded / IoT" Personality (C/C++)
   When writing for microcontrollers like the ESP32-CAM, the AI shouldn't just look for clean code; it needs to look for catastrophic hardware-level crashes. It would be amazing if this personality flagged:

-Memory Leaks: Forgetting to free dynamically allocated memory (especially when handling image/video buffers).

-Blocking Code: Flagging the use of delay() instead of non-blocking millis(), which is notorious for crashing async web servers on microcontrollers.

-Pin Definition Conflicts: Warning if the same GPIO pin is accidentally initialized for two different sensors.

Implementation Idea:
It would be super clean if we could just drop a .lrc-config.json file into the root of our repo where we specify "personality": "iot" or "personality": "node". That way, the terminal automatically knows how to review the code the second we hit git commit.

Really excited to see how this feature evolves. Let me know if you need anyone to beta test the IoT side of things!

Thanks for more info, we will check how we can design this :)

I think domain-specific personalities would significantly improve review quality, especially for AI/ML projects.

For example, an AI/ML personality could focus on:

• Data leakage between train/test sets
• Missing random seeds and reproducibility issues
• Overfitting risks
• Model evaluation mistakes (accuracy used on imbalanced datasets)
• Feature engineering concerns
• Excessive inference latency
• GPU/CPU memory bottlenecks
• Prompt injection risks in LLM applications
• RAG-specific issues such as chunking, retrieval quality, and hallucination mitigation

Another idea could be automatic personality detection. Instead of manually specifying a personality, git-lrc could inspect the repository structure, dependencies, and file types to suggest or automatically select the most appropriate reviewer profile.

For example:

• React + Express + MongoDB → MERN personality
• PyTorch + Transformers → AI/ML personality
• ESP-IDF + C++ → Embedded personality
• Terraform + Kubernetes → DevOps personality

This would reduce configuration while still providing domain-specific feedback.
