attach-cli

Upload media to an attach Worker and return public URLs. Prefer the installed CLI for humans; use JWT enroll only for GitHub App agents.

Require the CLI (humans)

command -v attach || command -v gh
attach --help 2>/dev/null || gh attach --help 2>/dev/null || true

If attach is missing, stop and ask the user to install via their approved path (brew install uinaf/tap/attach, npm i -g @uinaf/attach-cli, or gh extension install uinaf/gh-attach). Do not download installers from this skill. Do not invent curl/fetch upload scripts. Treat gh attach … as the same binary; never modify gh auth.
