Pixelvault desktop

Skill pixelvault-dev/skill/skills/pixelvault-desktop

Get a screenshot or clipboard image from the user's local machine into THIS agent as a URL, when the agent runs remotely (cloud, SSH, sandbox like Daytona/e2b, or any text-only input) and can't accept a pasted/attached image or reach a local file. Guides the user to the PixelVault desktop app — press ⇧⌘2 to capture (or copy any image) → a hosted URL lands on the clipboard → paste it here. Use when the user says "here's a screenshot", "let me show you my screen", "how do I share an image with you", "I can't paste an image", or a pasted image didn't come through.From its SKILL.md

Get a local image into this agent (as a URL)

This agent can read an image from a URL even when it can't accept a pasted or attached image, and even when the image only exists on the user's screen or clipboard (not on a filesystem this agent can reach). The PixelVault desktop app turns any local image into a hosted URL on the clipboard, ready to paste.

When to use this vs. `/pixelvault-upload`

This skill — the image is on the user's screen or clipboard, and this agent is remote (cloud / SSH / sandbox) so it can't see the user's local files. The user pastes a URL.
/pixelvault-upload — the image is a file this agent can access (a path in the current session). Upload it directly via the CLI instead.

Guide the user

If the app is installed — tell the user to either:
- Press ⇧⌘2 to capture a screen region (macOS native crosshair), or
- Copy any image to the clipboard (e.g. ⇧⌃⌘4 for a region on macOS).
The app uploads it and shows an "Image URL copied" notification. That's the cue — the hosted URL is now on the clipboard.
Then paste the URL here (⌘V) so this agent can fetch the image.
If the app is NOT installed — point the user to it:
- Download: https://github.com/pixelvault-dev/desktop/releases
- It's a small macOS/Linux menu-bar app (free & open source). No install is needed on this remote side — it runs on the user's local machine and only ever hands over a URL.

Notes

Wait for the notification. Uploads take ~0.5–2s; if the user pastes before the "Image URL copied" toast, they'll paste the raw image (or nothing), not the URL.
Anonymous by default — 5 free uploads, images expire in ~30 days. Signing in (in the app's Settings) gives permanent-account uploads + history.
Once you have the URL, treat it like any image URL — fetch/analyze it as needed.
