AI Code Review Agent (with AI Architect vs without AI Architect)
From single-repo reviews to system-wide insights
The AI Code Review Agent becomes significantly more powerful when paired with AI Architect.
Below is a clear explanation of how the agent behaves in each setup and why AI Architect unlocks much deeper, system-level insights.
AI Code Review Agent without AI Architect
The standard AI Code Review Agent analyzes code at the repository level.
It creates a within-repo knowledge graph by building:
Abstract Syntax Trees (ASTs)
Symbol indexes
Local dependency relationships
This allows it to perform strong, context-aware code reviews within a single repository, including:
Identifying issues in the diff
Understanding dependencies inside the repo
Checking for consistency and correctness within that project
Suggesting improvements based on local patterns
However, the agent’s visibility stops at the repository boundary. It cannot detect effects on other services or codebases.
AI Code Review Agent powered by AI Architect
When AI Architect is enabled, the AI Code Review Agent gains a complete view of your entire engineering ecosystem.
AI Architect builds a cross-repository knowledge graph that maps:
All services
Shared libraries
Modules and components
Inter-service dependencies
Upstream and downstream call chains
With this system-level understanding, the agent can perform much deeper analysis.
Key capabilities unlocked by AI Architect
1. Cross-repository awareness
The agent understands how code in one repo interacts with code in others — crucial for microservices and distributed systems.
2. Cross-repo impact analysis
During a pull request review, the agent can identify:
What breaks downstream if you change an interface
Which services call the function you updated
Which teams or repos depend on your changes
Whether the update introduces architecture-wide risks
3. Architecture-level checks
The agent evaluates your changes not just for correctness, but for their alignment with the overall system design.
4. Early problem detection across the entire codebase
Ripple effects, breaking changes, or dependency violations that traditionally appear only in staging or after deployment can now be flagged directly during review.
