Printing Press Library

Nothing is more valuable than time and money. In a world of AI agents, that's speed and token spend. A well-designed CLI is muscle memory for an agent: no hunting through docs, no wrong turns, no wasted tokens. The CLI Printing Press prints those CLIs. This repo is the catalog of CLIs already printed and ready to install.

600 CLIs across 22 categories.

Browse them all at printingpress.dev.

Three to try first:

• ESPN (sniffed, no official API). "Tonight's NBA playoff games with live score, series state, each team's leading scorer's stat line, and any injury or lineup news from the last 24 hours." One call.
• flight-goat (Kayak nonstop search plus sniffed Google Flights). "Non-stop flights over 8 hours from Seattle for 4 people, Dec 24 to Jan 1, cheapest first." Two sources, one query.
• sentry-pp-cli (local SQLite mirror, SQL across orgs and projects). "Every issue first seen in the last release whose error rate is climbing across two projects." Compound queries the Sentry API can't answer.

Agent-native discovery

If you use OpenClaw, Hermes, Claude Code, Codex, Cursor, or another harness that supports agent skills, install the Printing Press Library discovery skill first. It helps your agent search the catalog, choose the right focused pp-* skill, and defer CLI binary setup until the focused skill says it is needed.

OpenClaw users can install the published skill from ClawHub:

clawhub install printing-press-library

Humans and agents on Vercel Agent Skills-compatible harnesses can install the same discovery skill from this repo:

npx skills add mvanhorn/printing-press-library/skills/printing-press-library -g -y

Or from the repo root by selecting the catalog skill explicitly:

npx skills add mvanhorn/printing-press-library -g -y --skill printing-press-library

Hermes users can install it from the command line:

hermes skills install mvanhorn/printing-press-library/skills/printing-press-library

Or from inside the Hermes chat TUI:

/skills install mvanhorn/printing-press-library/skills/printing-press-library

Once you know the specific tool you want, install the focused skill directly.

For Vercel Agent Skills-compatible harnesses:

npx skills add mvanhorn/printing-press-library/cli-skills/pp-espn -g -y

For Hermes from the command line:

hermes skills install mvanhorn/printing-press-library/cli-skills/pp-espn

For Hermes from inside the chat TUI:

/skills install mvanhorn/printing-press-library/cli-skills/pp-espn

The existing npm installer remains the right path for humans, scripts, and CLI-first setup.

Discover and install

The fastest way to start — install four hand-picked CLIs and skills in one command:

npx -y @mvanhorn/printing-press-library install starter-pack

The -y flag only tells npx to run the installer package without an interactive npm prompt; discovery commands like list and search do not install catalog CLIs.

The starter pack: espn (live sports), flight-goat (flight search), movie-goat (movie discovery), recipe-goat (recipe ranking).

Every install pulls the Go binary and the focused skill in one shot. Pass --cli-only or --skill-only if you want just one half.

One tool:

npx -y @mvanhorn/printing-press-library install espn

Several at once (bundles and CLI names mix freely):

npx -y @mvanhorn/printing-press-library install espn sentry dub
npx -y @mvanhorn/printing-press-library install starter-pack cal-com

Under the hood: the npm package is a thin orchestrator that reads the live catalog in registry.json, resolves each CLI's Go module path, and pins released Go CLI builds to the catalog's full source_commit (falling back to @latest only for legacy entries without release metadata). This prevents accidental drift from a later main update; it does not authenticate the mutable live catalog or the separately versioned skill installer. The matching skill comes from cli-skills/pp-<name>.

Useful commands:

npx -y @mvanhorn/printing-press-library list
npx -y @mvanhorn/printing-press-library search flights
npx -y @mvanhorn/printing-press-library list --category travel
npx -y @mvanhorn/printing-press-library list --installed
npx -y @mvanhorn/printing-press-library update espn
npx -y @mvanhorn/printing-press-library uninstall espn --yes

@mvanhorn/printing-press-library replaces the older @mvanhorn/printing-press npm package. The unambiguous printing-press-library binary is the catalog installer: use it to browse available CLIs, search by keyword, install the matching Go binary plus focused agent skill, and keep installed tools fresh.

Install accepts catalog slugs and generated binary names, so both airbnb and airbnb-pp-cli resolve to the Airbnb tool.

Discovery commands print human-readable cards by default and support --json for scripts and agents:

npx -y @mvanhorn/printing-press-library search flights --json
npx -y @mvanhorn/printing-press-library list --category food-and-dining --json

Focused skills

When you already know the tool you want, install just that skill:

npx skills add mvanhorn/printing-press-library/cli-skills/pp-espn -g

Then use the focused slash skill directly:

/pp-espn lakers score
/pp-flightgoat sea to lax dec 24 to jan 1 nonstop
/pp-weather-goat phoenix forecast

Each /pp-<name> skill is a focused interface for one CLI.

Catalog

Tools grouped by category, sourced from registry.json. Each row links to the tool source, its focused direct-install skill, and the latest release.

Name	Skill	Release	What it does
1688	/pp-1688	latest	The free, offline, agent-native 1688 wholesale sourcing CLI — keyword search with the signals the web UI buries (回头率 reorder rate, factory-verified status, supplier trade scores, price drift), persisted to a local store no scraper tracks over time.Printed by Hamza Qazi
1password	/pp-1password	latest	Agent-safe command layer over the official 1Password CLI and SDK service-account workflows.Printed by Cathryn Lavery
3cx-xapi	/pp-3cx-xapi	latest	Every 3CX Configuration API (XAPI) object in one Go binary, with a local mirror of your whole PBX, offline search, config diffing, and cross-entity auditing no 3CX tool has.Printed by

Binary-only install

If you only want the binary and not the companion skill, install directly with Go 1.26.10 or newer:

go install github.com/mvanhorn/printing-press-library/<path>/cmd/<binary>@latest

A few worked examples:

go install github.com/mvanhorn/printing-press-library/library/media-and-entertainment/espn/cmd/espn-pp-cli@latest
go install github.com/mvanhorn/printing-press-library/library/monitoring/sentry/cmd/sentry-pp-cli@latest
go install github.com/mvanhorn/printing-press-library/library/travel/flightgoat/cmd/flightgoat-pp-cli@latest

For the MCP server companion:

go install github.com/mvanhorn/printing-press-library/library/media-and-entertainment/espn/cmd/espn-pp-mcp@latest
claude mcp add espn-pp-mcp -- espn-pp-mcp

If a CLI needs credentials, the focused skill and the per-CLI README document the required environment variables.

registry.json

Each published tool is self-contained: source code, a local README, a .printing-press.json provenance manifest, and the manuscripts from the printing run. cli-skills/pp-* is a generated mirror of each library SKILL.md, produced by tools/generate-skills/main.go.

What endorsed means

Published tools in this repo are validated at publication time and during deliberate baseline sweeps against:

1. Generation from an API spec or captured interface through the CLI Printing Press
2. Validation checks: build, vet, reachable Go vulnerability scan, help, version, plus the structural dogfood and runtime verify gates
3. Provenance capture through .printing-press.json and .manuscripts/

Some tools are refined after generation. The generated artifacts remain in the tool directory so the provenance stays inspectable.
