## Summary  
The paper proposes a closed‑loop framework that lets AI coding agents continuously improve by turning human review comments into persistent behavioral rules. Each accepted comment is codified as a rule stored in a version‑controlled instruction file, allowing the agent to self‑detect error classes without ever updating its model weights. This approach enables persistent learning across multiple sessions on real production codebases, shifting focus from low‑level correctness to higher‑level design validation.

## Key Contributions  
- A closed‑loop accumulation system that converts human review comments into version‑controlled behavioral rules.  
- Empirical evidence of a 0 % recurrence rate for ruled‑against error classes across 11 working sessions, moving review effort from correctness checks to design validation.  
- Persistent cross‑session learning without model weight updates, with transferable rule sets across heterogeneous agent interfaces.

## Methodology  
The authors built an accumulating rule set stored in a version‑controlled instruction file and paired it with a self‑review checklist that runs before any code is submitted. Human reviewers supply feedback; each comment is parsed into concrete behavioral rules (e.g., “no undefined variables”, “use snake_case”). The agent executes the checklist, validates its generated code against the rule set, and only proceeds if all checks pass. Automated validation monitors the integrity of the growing rule set to prevent corruption.

## Results  
Deployed on a 35+ service microservices platform, the rule set expanded from five initial behavioral rules to eighteen, added fifteen language‑specific standards, and incorporated a fifteen‑item self‑review checklist—all derived from real review feedback. The cumulative effect was a measured shift in reviewer effort toward design‑level validation. Crucially, the recurrence rate for error classes that had been ruled against dropped to zero across all sessions, demonstrating persistent cross‑session learning.

## Significance  
This work introduces a weight‑free, long‑term learning mechanism that captures engineering wisdom from human collaborators, enabling AI agents to improve continuously on real codebases. It addresses an orthogonal dimension—behavioral consistency over time—that existing benchmarks ignore, offering a pathway toward truly self‑improving coding assistants.
