What this skill does
OfferUp — Printing Press CLI Prerequisites: Install the CLI This skill drives the offerup-pp-cli binary. You must verify the CLI is installed before invoking any command from this skill. If it is missing, install it first: 1. Install via the Printing Press installer. It defaults binaries to $HOME/.local/bin on macOS/Linux and %LOCALAPPDATA%\Programs\PrintingPress\bin on Windows: 2. Verify: offerup-pp-cli --version 3. Ensure the reported install directory is on $PATH for the agent/runtime that will invoke this skill. If the npx install fails (no Node, offline, etc.), fall back to a direct Go install (requires Go 1.26.6 or newer): If --version reports "command not found" after install, the runtime cannot see the binary directory on $PATH. Do not proceed with skill commands until verification succeeds. When to Use This CLI Use this CLI when an agent or user needs local-marketplace data from OfferUp: searching listings near a ZIP, pulling an item's full detail, vetting a seller, or — its real edge — answering price questions (what's the going rate, what's underpriced, what dropped) over a local store of listings. All of that works with no login. When logged in (auth login --chrome), it also manages your own account: your listings (view active/archived, mark sold, archive), saved lists, and messages. It does not create listings (OfferUp web posts Jobs only; listing creation is mobile-app-only) or send messages. When Not to Use This CLI The public commands are read-only. The authenticated commands add two account mutations — my-listings mark-sold and my-listings archive — both gated behind login and an explicit --confirm. Do not use this CLI to create/post a listing (mobile-app-only), send messages, make or accept offers, purchase, or otherwise change remote state it does not expose. Unique Capabilities These capabilities aren't available in any other tool for this API. …
