Create and configure a GitHub App so the assistant can push commits, open PRs, and comment under its own bot identity. Use when the user wants the assistant to have its own GitHub identity, or when setting up git push access for the first time.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
## Overview This skill creates a **GitHub App** under a GitHub organization, giving the assistant its own bot identity for git operations. After setup, commits, PRs, and comments will attribute to `<app-name>[bot]` instead of the user's personal account. **Total manual effort: 7 interactions** — Continue to GitHub → Create App → 3 secure credential prompts → Install on repo → (optional) upload avatar. Everything else is automated. > **Note:** This skill currently supports GitHub **organizations** only, not personal accounts. ## What Gets Created - A **GitHub App** owned by the org (not the user's personal account) - **Installation** on selected repositories with configurable permissions (default: `contents:write`, `pull_requests:write`, `checks:read`, `metadata:read`) - **Credentials** stored in the assistant's encrypted vault (7 fields) - **Token helper script** at `bin/gh-app-token.mjs` (in the workspace root) for refreshing auth tokens ## Prerequisites - User must be an **admin** of the GitHub organization - User must be **logged into GitHub** in their browser - The `assistant credentials` CLI must be available …

How to install
mdr add vellum-ai/vellum-assistant/vellum-github-app-setup@sha256:46d8018a58f18f6fThe line at the top of this page pins the label v1.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
