Same command for any agent — swap --agent for codex, cursor, copilot.

# Upload images to GitHub (gh-image) GitHub has **no public API** for image uploads — the web UI uses an internal endpoint that mints `user-attachments` URLs scoped to the repo's visibility. [`gh-image`](https://github.com/drogers0/gh-image) (MIT, © drogers0) replicates that flow as a `gh` CLI extension, so an agent can upload a local image from the terminal and get a ready-to-embed Markdown image line back. ## Overview This skill drives `gh-image` to turn a local image file into a hosted GitHub `user-attachments` URL, then embeds that URL into a pull request, issue, or comment. It is the missing "attach a screenshot" capability for terminal agents. ## When to Use This Skill Use this skill when asked to: - "Attach a screenshot to the PR" or "add an image to the PR description" - "Put this image in the issue" / "comment with these screenshots" - "Show the test results / before-and-after in the PR" - Embed any local image into GitHub Markdown without leaving the terminal ## How It Works ### Step 1: Verify prerequisites ```bash gh auth status # gh installed & authenticated gh extension list | grep -q 'drogers0/gh-image' \ || gh extension install drogers0/gh-image # review/pin the exte

gh auth status                                   # gh installed & authenticated
gh extension list | grep -q 'drogers0/gh-image' \
Use an absolute path; --repo is optional inside a repo working dir.
gh image "/abs/path/screenshot.png" --repo <owner>/<repo>
printf '%s\n\n## Screenshots\n\n%s\n' "$BODY" "$MD" \
gh pr view <pr> --repo owner/repo --json body -q .body   # confirm URL present
