At a glance
Explains how a public GitHub repository is built by fetching its GitDiagram architecture diagram, components and optional explainer video.
- Works in 5 steps: Work out the repository as owner/repo.… → Call get_repository_diagram with… → Answer the user's actual question from… → …
- Understanding how an open-source project is organized before contributing
- Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
- Getting an architecture or system diagram of a public GitHub repo
What it does
The agent works out the repository as owner and repo, from a github.com URL or the local clone's origin remote, or searches diagrams by project name and asks when several match. It then calls get_repository_diagram, which returns a written explanation, the main components with their paths, how they connect, Mermaid source and an interactive diagram link.
Answers cite component labels and source paths and include the interactive link. Because the diagram is AI-generated from the repository's files, the agent checks the code at the cited path when certainty matters, and if no diagram exists it says so and shares the link that creates one. get_explainer_video returns a narrated video when one exists. Only public GitHub repositories are covered, and access is read-only.
When your agent uses it
- Understanding how an open-source project is organized before contributing
- Getting an architecture or system diagram of a public GitHub repo
- Starting work in an unfamiliar codebase hosted on GitHub
- Finding a shareable explainer video for a repository
Example prompts
- “How is the vercel/next.js repository structured?”
- “Give me an architecture diagram for this repo and tell me where the API layer lives.”
- “Is there an explainer video for the tailwindcss repository?”
Requirements
- Access to the GitDiagram tools for finding and fetching repository diagrams
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Work out the repository as owner/repo. Take it from a github.com URL the user gave, or, when working inside a local clone, from its origin…
- Call get_repository_diagram with owner/repo. It returns GitDiagram's written explanation, the main components with the paths they live in…
- Answer the user's actual question from that result. Name components by their labels, cite their source paths, and give the interactive…
- If GitDiagram has no diagram yet, say so plainly and share the link from the result, which makes one on gitdiagram.com in about a minute…
- If the user wants something to watch or share, call get_explainer_video for the repository's narrated explainer video, when one exists.
What it can do on your machine
Read from SKILL.md and the folder at commit 10c0ff8. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
GitDiagram Repo Architecture loads about 429 tokens when it runs. Until then it costs about 80 tokens; SKILL.md has 216 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- repo-architecture
- description
- Explain how a public GitHub repository is built using GitDiagram's architecture diagram. Use when the user asks how a GitHub repository or open-source project is structured or organized, wants an architecture or system diagram of a repo, or is starting work in an unfamiliar codebase hosted on GitHub.
Explain a repository's architecture with GitDiagram
- Work out the repository as
owner/repo. Take it from a github.com URL the user gave, or, when working inside a local clone, from itsoriginremote. If the user only named a project, callfind_repository_diagramswith the name and pick the match the user means; ask if several fit. - Call
get_repository_diagramwithowner/repo. It returns GitDiagram's written explanation, the main components with the paths they live in, how they connect, Mermaid source and the interactive diagram link. In ChatGPT the diagram also appears as an interactive view. - Answer the user's actual question from that result. Name components by their labels, cite their source paths, and give the interactive diagram link so they can explore it. The diagram is AI-generated from the repository's files: when the user needs certainty about a detail, check the code at the cited path.
- If GitDiagram has no diagram yet, say so plainly and share the link from the result, which makes one on gitdiagram.com in about a minute. Don't describe an architecture you haven't read.
- If the user wants something to watch or share, call
get_explainer_videofor the repository's narrated explainer video, when one exists.
GitDiagram only covers public GitHub repositories and is read-only: it never changes anything on GitHub.
