Skill: upload-photo

Upload local image files to Vercel Blob and return public URLs for sharing.

When to use

Use whenever an image or screenshot needs a public URL, including PR comments, docs, and sharing.

Requires

BLOB_READ_WRITE_TOKEN must be set in the environment. If it is missing, use the get-env-var skill to fetch it from Infisical:

export BLOB_READ_WRITE_TOKEN="$(infisical secrets get BLOB_READ_WRITE_TOKEN --plain --silent)"

Upload

Run the bundled script from the repo root:

node .opencode/skills/upload-photo/scripts/upload.mjs <file.png> [more files...] [--prefix <path/prefix>] [--stable]

It prints one public URL per line (https://<store>.public.blob.vercel-storage.com/...). --prefix defaults to uploads/<YYYY-MM-DD>. By default Vercel Blob appends a random suffix to the pathname for collision safety; --stable disables that (x-add-random-suffix: 0) for deterministic URLs, so overwrites are possible.

Embed

Use Markdown:

![alt](url)

Or HTML for size control in GitHub comments:

<img src="url" width="700">

Rules

• Never log BLOB_READ_WRITE_TOKEN.
• The store is public; do not upload anything sensitive.
• Prefer PNG, JPEG, or WebP images.
