pp-numista
Every Numista catalogue and collection feature, with offline FTS5 search and a monthly-quota tracker no Numista SDK has. Trigger phrases: `look up a coin on numista`, `what is my coin collection worth`, `track numista prices`, `check my numista quota`, `import my coins into numista`, `browse numista series`, `use numista-pp-cli`, `run numista-pp-cli`.
Why this skill is useful
Adds executable scripts for quota management and batch processing that aren't available in the Numista SDK.
What it needs

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: numista-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 Reach for numista-pp-cli when you have a Numista API key and need quota-aware automation over the catalogue and your collection. Ideal for: bulk-importing a collection from another tracker, running scheduled price refreshes on watched coins, computing a current valuation of an entire collection, or pulling a full series (every year, every grade) for one type into a local store for analysis. Skip it when one ad-hoc lookup is all you need — the Numista web UI is fine for that. Unique Capabilities These capabilities aren't available in any other tool for this API. Quota economics --quota — Print the current month's used/remaining/reset Numista quota and exit, with zero API calls. Reach for this before any batch or crawl to know whether the operation fits today's budget — zero quota cost. …
