Integration details

Description

GitDiagram shows how a public GitHub repository is built. Ask about a repository, for example "Show me the architecture of fastapi/fastapi", and you get its architecture diagram: an interactive map of the main components and how they connect, which you can pan, zoom and open full screen, and where every component opens its source code on GitHub. With the diagram, ChatGPT also receives GitDiagram's written explanation of how the codebase is organized, the list of components with the paths they live in, how they connect, and the Mermaid source, so it can answer follow-up questions about the code and point you to the right files. You can also search GitDiagram's library of diagrams by owner or repository name, and get a repository's narrated explainer video and its transcript when one exists. It's for anyone getting to know an unfamiliar codebase: onboarding to a project, evaluating an open-source dependency, preparing a first contribution, or explaining how a project works. Limitations: GitDiagram covers public GitHub repositories only. The plugin reads diagrams GitDiagram has already made; when a repository has none yet, it gives you a link to gitdiagram.com, where the diagram is made in about a minute, and after that the plugin can read it. Diagrams are AI-generated from the repository's files and can miss details, so check anything important against the code. The plugin is read-only, never changes anything on GitHub or elsewhere, and needs no account.

Tools

3 tools agents can invoke

Get the architecture of a public GitHub repository from GitDiagram (gitdiagram.com): a written explanation of how the codebase is organized, its main components with the source paths they live in, how those components connect, and a Mermaid flowchart of the whole system, plus a link to the interactive diagram, where every component opens its code on GitHub. Use it whenever the user wants to understand, visualize, map or explain a GitHub repository's or open-source project's architecture, structure, main modules or data flow, wants an overview before reading unfamiliar code, or asks for an architecture or system diagram of a repo. Read-only and fast: it returns the diagram GitDiagram has already made. If none exists yet, it returns a link that makes one when opened in a browser. Public repositories only. In chat apps that show interactive views, the result also appears as a zoomable diagram whose components open their code on GitHub.
get_repository_diagram
Get GitDiagram's narrated explainer video of a public GitHub repository, if one has been made: the link to watch and share it, its title and length, and the full narration transcript, a plain-language walkthrough of what the project is for, what people do with it and how its main parts fit together. Use it when the user wants a video about a repository, something to watch or share instead of read, or a short spoken-style summary of a project. Read-only: it never makes a video; when none exists it says so and links the page where one can be made.
get_explainer_video
Search GitDiagram's library of ready-made architecture diagrams of public GitHub repositories by owner or repository name. Matches any part of "owner/repo" (e.g. "langchain", "vercel/", "react-native") and returns up to 10 repositories, most-starred first, each with its interactive diagram link. Use it to find a project's exact owner/repo from its name, or to list which repositories of an owner or topic already have diagrams. It searches repository names only, not code or file contents.

How do I improve GitDiagram's ChatGPT Plugin discoverability?

The levers are the listing surface agents actually read: names, descriptions, keywords, tool metadata, and registry health. Which lever matters depends on where discovery breaks, which is what continuous measurement shows.
