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 (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.
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.
Use this skill when asked to:
gh auth status # gh installed & authenticated
gh extension list | grep -q 'drogers0/gh-image' \
|| gh extension install drogers0/gh-image # idempotent install
gh-image does not use the gh token for the upload (that endpoint rejects
tokens). It needs a GitHub user_session cookie, resolved in this order:
--token <value> flag → GH_SESSION_TOKEN env var (use in CI/headless) → a
logged-in browser's cookie store (default for local use).
# Use an absolute path; --repo is optional inside a repo working dir.
gh image "/abs/path/screenshot.png" --repo <owner>/<repo>
gh image prints Markdown to stdout, one line per image:
Capture that output — it is the embeddable reference.
MD="$(gh image "/abs/path/shot.png" --repo owner/repo)"
BODY="$(gh pr view <pr> --repo owner/repo --json body -q .body)"
printf '%s\n\n## Screenshots\n\n%s\n' "$BODY" "$MD" \
| gh pr edit <pr> --repo owner/repo --body-file -
Use gh pr comment, gh issue edit, or gh issue comment with --body-file -
for other targets. Always pass --body-file - (not inline --body) so multi-line
bodies and special characters can't break shell quoting.
