DeepGit – Ridiculously complex Deep Research Agent helping you find Gold in the GitHub Haystack

A deep dive into the inner workings of DeepGit, from query expansion to relevance synthesis


A LangGraph-powered agent that digs deeper than any search bar ever could


User Interface

DeepGit's interface is designed for speed and clarity.

Just enter your search query. On the bottom, a ranked table of repositories appears, complete with:

  • Repository name and description
  • Relevance score out of 100
  • Key metadata: stars, forks, last commit date

Every result row can be expanded to show an AI-generated summary of why that repo was chosen.


The Problem: GitHub’s Clutter of Chaos

GitHub hosts over 100 million repositories—an open-source paradise and, at the same time, a labyrinth.

  • Keyword searches often drown you in irrelevant results.
  • Star counts can be misleading: high-star projects may be abandoned.
  • Manual filtering wastes hours of your time.

DeepGit flips the script: it focuses on relevance over popularity, using multiple AI-driven signals to surface truly meaningful repositories.


Enter DeepGit: The Research Agent You Didn’t Know You Needed

DeepGit orchestrates a series of intelligent steps—each driven by LangGraph agents—to deliver pinpoint results. Here’s a detailed look:

1. Query Expansion

When your input is vague, DeepGit first uses a large language model to rewrite it into a precise search phrase.
For example, “task scheduler Python” becomes “lightweight Python task scheduling library with active maintenance and clear documentation.”

2. Hybrid Dense Retrieval

With your refined query, DeepGit uses semantic embeddings stored in FAISS to pull a broad candidate set—not limited by exact keyword matches.

3. Cross-Encoder Re-Ranking

A second LLM pass scores each candidate for relevance. This step weeds out superficial matches and promotes projects that truly align with your intent.


Insight Delivery

After re-ranking, DeepGit presents a final list where each entry includes:

  • AI-generated summary of the repository’s functionality
  • Key metrics (stars, forks, open issues, last activity)
  • Repository URL for one-click access

4. Documentation Intelligence

DeepGit scrapes and parses README files and markdown docs to extract:

  • Project purpose and features
  • Installation and usage instructions
  • High-level architecture diagrams (when available)

This ensures you understand a repo’s core without clicking through dozens of pages.


5. Codebase Mapping

Under the hood, DeepGit analyzes the file structure:

  • Counts major languages and highlights polyglot repos
  • Measures complexity from line counts and dependency graphs
  • Flags missing tests or outdated dependencies

6. Community Insights

Beyond raw metrics, DeepGit factors in community health:

  • Issue resolution time
  • Pull request review activity
  • Contributor diversity

This helps surface projects that are actively maintained and well-supported.


7. Relevance Synthesis

All signals—semantic score, documentation quality, code structure, and community metrics—are fused into a single relevance score, personalized to your needs.


LangGraph Workflow Visualization

LangGraph coordinates each of these steps as independent agents that communicate and iterate. The result is a fluid, dynamic research pipeline:
