See what coding agents see when they look at your codebase.

In 2023, when Applied AI products were in their initial stages, I had more questions than answers. Those questions drove me to create my own coding assistant. The main engine for most code assistants is to understand the repo, its relationships, and pull the right files during runtime to create context. Part of that exploration became grasprepo: a tool that lets anyone see under the hood for their repo.

What happens under the hood of coding agents?

Parse the AST Tree-sitter extracts every class, function and variable definition. The structural skeleton of your code.

Dependency Graph Symbols defined in one file and referenced in another create edges. A map of how information flows.

PageRank The same algorithm Google uses for web pages. Files referenced by other important files rise to the top.

Code Churn Commits, contributors, lines changed. 200 commits by 8 developers looks different from 5 commits by 1.

Prioritization Matrix Four quadrants: highest risk, isolated, stable, safe. Each tells you where to spend your time.

Rank	File	PageRank Score	Centrality

Files ranked by commit frequency over the last 6 months. High commit count + many contributors signals active, potentially volatile code. Low commits + single contributor signals stability.

Churn Distribution

The Prioritization Matrix

Combining churn data with structural importance gives you a risk-weighted prioritization across four quadrants:

High Churn + High Rank: Highest risk refactoring target. The file is both fragile and consequential. Handle with care.

High Churn + Low Rank: Fragile but isolated. Refactor freely, the blast radius is small.

Low Churn + High Rank: Stable and central. Leave it alone unless you have a strong reason.

Low Churn + Low Rank: Safe territory. Good place for new team members to start.

Hotspot Files (High Churn + High Rank)

The Abstract Syntax Tree: every symbol Tree-sitter extracted from this codebase. This is what coding agents "see" when they parse your code.
