1. Add the plugin. Run these from inside Claude Code, then start a new session so the /pss skill is discovered:

/plugin marketplace add arxhive/pss-plugin
/plugin install pss@pss

2. Install the pss CLI. The plugin needs the pss CLI on your PATH. Install the prebuilt binary (requires Node.js 18+):

curl -fsSL https://raw.githubusercontent.com/arxhive/pss-plugin/main/install.sh | sh

It installs a single self-contained pss to ~/.local/bin and prints how to add that directory to PATH if needed.

3. Authenticate the CLI. Sign in above, create a token on the tokens page, then run this and paste the token when prompted:

pss auth login

Then run /pss in any session to capture and share it. See the install guide.
