Attach GitHub Assets

Upload local files to GitHub via uploads.github.com/user-attachments/assets.

Contract: if loaded, run the script

This skill exists to call upload.sh. If it is loaded with a local file path in context, you MUST run the script — do not describe the flow, do not propose markdown without uploading, do not stop after acknowledging the request. The only correct trajectory ends with a gh/curl-backed upload and either a returned asset URL or a posted comment.

If no local file path is present and none can be inferred from conversation, output no-op: no local file path and exit — do NOT call upload.sh with a placeholder, a remote URL, or a guessed path.

When to Self-Invoke

Self-invoke ONLY when all of the following hold:

1. The user (or a calling skill) references a concrete local file path — absolute (/tmp/..., ~/Desktop/...) or relative to cwd — for an image (png, jpg, jpeg, gif, webp, svg) or video (mov, mp4, webm).
2. The destination is GitHub — a PR body, issue body, PR/issue comment, or /create-sub-issues flow.
