See the repository agent guide, section "Generated artifacts: registry.json, cli-skills/". --> Mercury — Printing Press CLI Prerequisites: Install the CLI This skill drives the mercury-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: mercury-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. Unique Capabilities These capabilities aren't available in any other tool for this API. workflow payment-plan — Builds a read-only approval plan with body, idempotency key, dry-run command, and execute command before payment or transfer writes. Agents can prepare exact write commands without moving money. workflow archive — Syncs supported Mercury resources into a local SQLite store for offline search and analytics. Reduces API calls and gives agents repeatable context. agent-context — Emits machine-readable command metadata for agents and MCP hosts. Improves autonomous command selection and reduces context waste.
