Uploads a local file (screenshot, image, PDF, zip, video) to GitHub user-attachments, downloads GitHub user-attachments, and embeds local files in a PR, issue, or comment. Use when asked to "attach a screenshot to the PR", "add an image to the issue", "embed before/after screenshots", "attach this file", or "download this GitHub attachment". Powered by `gh-attach`.
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
# gh-attach `gh attach` uploads a file to GitHub's internal user-attachments endpoint (no public API exists) and prints the URL, which GitHub auto-renders (image/video/file) wherever it's pasted. The URL inherits the repo's visibility, so private-repo uploads stay private. ## Prerequisites ```sh gh extension list | grep -q 'gh attach' || gh extension install sudosubin/gh-attach ``` Uploads use a GitHub browser session cookie, not the `gh` token. By default, `gh` must be authenticated so `gh-attach` can select the matching browser account. If the wrong account is selected, add `--browser <name> --profile <name>`. For headless use, set `GH_ATTACH_SESSION_TOKEN` to the bare `user_session` cookie value. Treat it as a full account credential. ## Steps **1. Upload**: Use an absolute quoted path. `-R` is optional inside a repository. For GHES, use `-R host/owner/repo`. The command prints the URL on one line. GitHub auto-renders it (image/video/file), so use it as-is: ```sh URL=$(gh attach "$FILE" -R <owner>/<repo>) ``` **2. Embed** (always `--body-file -`, e.g. `gh pr comment/edit`, `gh issue comment/edit`): ```sh …

How to install
mdr add github/awesome-copilot/gh-attach@sha256:a639b7a4d82d9b65The line at the top of this page pins the label git:20260805.bfefe9d, 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.
