The Problem Every Developer Knows
You are on vacation. Your phone buzzes. A build has failed.
You have no laptop, but the expectation is clear: find the problem and fix it. For developers who work with CI/CD pipelines, this scenario is routine. Pipelines fail at the worst moments, blocking releases and forcing engineers to sift through thousands of lines of diagnostic logs from wherever they happen to be.
How the System Works
The solution is a centralized dashboard that connects to your GitHub or GitLab repositories. From this dashboard, developers can monitor their build pipelines, tracking progress, successes, and failures from any device, including a mobile phone.
The Two-Agent Architecture
At the heart of the Code Healer is a two-agent AI architecture—meaning two distinct AI systems that work in sequence to diagnose and solve build failures.
The two agents are:
- A Local AI Agent: A lighter AI model that runs close to (or within) the developer's own infrastructure.
- An Advanced AI Agent: A more powerful AI model capable of deeper reasoning.
When a developer clicks Analyze Failure, the full log from the failed build is sent to the backend. The first task is to strip out the "noise"—CI logs frequently run to thousands of lines, but only a fraction of that content is relevant to understanding what went wrong.
Once the log is cleaned and structured, it is passed to the Local AI Agent, which produces:
- A failure summary: A plain description of what went wrong.
- Impacted files: The specific files likely connected to the failure.
- Possible solutions: Initial recommendations for fixing the issue.
- A semantic prompt: A compressed, structured description of the problem context.
Code-Level Fixes
Once the initial diagnosis is complete, the developer can click Advanced Assist. At this stage, a specialized AI agent creates a code patch—a specific set of code modifications intended to fix the identified issue.
Why Use a Local Agent at All?
Our team implemented the Local Agent for two concrete reasons:
1. Cost and Speed: Build logs are massive. Sending them in their entirety to a sophisticated AI model results in high latency and costs. The Local Agent serves as a compression layer, extracting only the pertinent context.
Continuous Improvement
The Local Agent is designed to operate independently, but the system also has a mechanism to improve its quality over time. When the Local Agent cannot resolve a problem with confidence, the system escalates to the Advanced Agent. The solution produced is then used as a training signal—feedback that gradually makes the Local Agent more capable.
The Broader Goal
The vision our team holds is that developers should build products, not spend their time diagnosing broken pipelines. By combining pipeline monitoring, AI-driven failure analysis, and code-level suggestions, we are moving toward a future where build systems can identify and resolve their own problems with minimal intervention.
