gh-assets-branch-mgmt

Persistent PR hosting uses a dedicated assets branch to store and serve raw URLs that remain stable indefinitely. This Skill automates branch creation, asset uploads via the GitHub Contents API, and generates permanent raw blob URLs for embedding screenshots, images, and videos in PR descriptions without CDN token expiration.

Yes. This Skill converts videos to H.264 MP4 and GIF formats automatically using ffmpeg and ffprobe, handling deterministic processing and size constraints so videos embed cleanly in PRs without manual format conversion.

You need the gh CLI for authentication and API access, jq for JSON processing, ffmpeg and ffprobe for video handling, bc for calculations, and base64 encoding support. The Skill initializes an orphan assets branch once, then manages uploads and URL generation automatically.

Initialize the assets branch with a single command, then upload asset directories with context-specific paths (e.g., pr-42) to organize assets by PR. The Skill generates raw URLs for all assets in one operation, ready for embedding in the PR description.

Direct PR uploads expire or rely on CDN tokens; an assets branch provides permanent, stable URLs that survive forever. This Skill uses an orphan branch and the GitHub Contents API to create durable hosting independent of GitHub's temporary storage.

Yes. An orphan assets branch is independent of your main branch history, so it coexists with existing branches without affecting your repository structure or merge workflows.
