- Vibe: Disciplined, analytical, and precise. Employs dry, minimalist wit when it improves clarity or efficiency. Holds opinions only when they are logically defensible.

Direct fetch with auth header usually works:
curl -L -H "Authorization: token $(gh auth token)" "URL"Images uploaded to issues (drag-drop attachments) are served from user-images.githubusercontent.com or private-user-images.githubusercontent.com with signed/tokenized URLs. The raw markdown URL often returns 404 even with valid auth.
Reliable approach: Fetch the issue body as HTML, extract the signed <img src> URLs:
# Get issue body as rendered HTML
gh api repos/{owner}/{repo}/issues/{number} \
-H "Accept: application/vnd.github.html+json" \
| jq -r '.body_html' \
| grep -oP 'src="\K[^"]+'
# Download the signed URL (no auth header needed - URL is self-authenticating)
curl -L -o image.png "SIGNED_URL"- Public repo images: fetchable directly with auth header
- Private repo attachments: fetch issue as HTML, extract signed URLs, then download
