What it does
Pp Open Library is an agent skill from mvanhorn/printing-press-library. Use Open Library source-backed recipes for book search, ISBN edition lookup, author works, work metadata, editions, and subject browsing. Trigger phrases: Open Library, book metadata, ISBN lookup, author bibliography, editions, subject books, open-library-pp-cli.
Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Research & Science, covering Citation management. The repository describes itself as: Official library of CLIs generated by the CLI Printing Press. Endorsed, tested, and community-contributed. The licence is Apache-2.0.
When your agent uses it
- Phrases: Open Library
- Author bibliography
- Open-library-pp-cli
Example prompts
- “/pp-open-library”
Requirements
- Node.js
- Pre-approved tools (allowed-tools): Read, Bash
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.
- Install via the Printing Press installer. It defaults binaries to $HOME/.local/bin on macOS/Linux and…
- Verify: open-library-pp-cli --version
- Ensure the reported install directory is on $PATH for the agent/runtime that will invoke this skill.
What it can do on your machine
Read from SKILL.md and the folder at commit 76de244. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
ReadBash
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
gonpx
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use npx, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Pp Open Library loads about 1.2k tokens when it runs. Until then it costs about 70 tokens; SKILL.md has 422 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check: notes
The automated check noted patterns worth knowing about, such as sudo or a known installer.
- NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
allowed-tools: Read, Bash
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Prerequisites: Install the CLI
This skill drives the open-library-pp-cli binary. You must verify the CLI is installed before invoking any command from this skill. If it is missing, install it first:
- Install via the Printing Press installer. It defaults binaries to
$HOME/.local/binon macOS/Linux and%LOCALAPPDATA%\Programs\PrintingPress\binon Windows:bash npx -y @mvanhorn/printing-press-library install open-library --cli-only - Verify:
open-library-pp-cli --version - Ensure the reported install directory is on
$PATHfor 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). This installs into $GOPATH/bin (default $HOME/go/bin), so add that directory to $PATH instead:
go install github.com/mvanhorn/printing-press-library/library/media-and-entertainment/open-library/cmd/open-library-pp-cli@latestIf --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
Use open-library-pp-cli when an agent needs source-backed Open Library metadata:
- Search for book/work candidates by title or keyword phrase.
- Resolve ISBNs to Open Library edition metadata.
- Find an author record and fetch a bounded sample of their works.
- Fetch canonical work metadata by Open Library work ID.
- List bounded editions for a known work.
- Browse subject works and optional subject facets.
When Not To Use
- Do not use it for borrowing, waitlists, patron data, account actions, or catalog edits.
- Do not use it for bulk harvesting; use Open Library data dumps for bulk access.
- Do not scrape Open Library HTML pages.
- Do not treat subject facets as stable; Open Library documents the Subjects API as experimental.

Setup
No API key is required.
The module declares go 1.26.4 so environments with Go toolchain auto-download disabled should use Go 1.26.4 or newer for direct installs.
For regular or frequent use, configure a request identity:
export OPEN_LIBRARY_USER_AGENT="my-research-tool"
export OPEN_LIBRARY_CONTACT_EMAIL="you@example.org"Without OPEN_LIBRARY_CONTACT_EMAIL, keep requests near Open Library's documented non-identified rate posture of 1 request per second.
Recipes
Book Search
open-library-pp-cli book "Designing Data-Intensive Applications" --limit 5 --agentUse this to seed a bibliography with compact work candidates, author names, first publish year, edition count, ISBN hints, and source URLs.
ISBN Lookup
open-library-pp-cli isbn 9780131103627 --agentUse this when the workflow has an ISBN and needs edition-level metadata.
Author Works
open-library-pp-cli author "Ursula K. Le Guin" --limit 5 --agentUse this to identify an author and fetch a bounded sample of works.
Work Metadata
open-library-pp-cli work OL45804W --agentUse this when a workflow already has an Open Library work ID.
Editions
open-library-pp-cli editions OL45804W --limit 10 --agentUse this to compare editions for a known work without bulk-fetching every record.
Subjects
open-library-pp-cli subjects "distributed systems" --details --limit 10 --agentUse this for adjacent-book discovery. Keep the experimental Subjects API caveat with downstream notes.
Source Coverage
open-library-pp-cli sources --agent
open-library-pp-cli doctor --agentUse these before a larger workflow to confirm rate-limit posture, optional request identity, source coverage, and non-goals.
