What it does
Printing Press Library is an agent skill from mvanhorn/printing-press-library. Use when looking for a CLI, API wrapper, scraper, data-source tool, automation tool, or focused agent skill for a task; searches the Printing Press Library and installs matching tools.
Its SKILL.md is about 4.8k 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 Backend & APIs, covering Third-party API integration and Web scraping. The repository describes itself as: Official library of CLIs generated by the CLI Printing Press. Endorsed, tested, and community-contributed.
When your agent uses it
- Looking for a CLI
- Data-source tool
- Automation tool
- Focused agent skill for a task
Example prompts
- “/printing-press-library”
Requirements
- Node.js
Workflow steps
7 steps, taken from the first numbered list in SKILL.md.
- Clarify the user goal only if needed.
- Search the catalog with the library CLI first.
- Select deliberately.
- Install through the library installer when the selected tool is useful.
- Make the newly installed skill visible to the running agent.
- Verify before claiming success.
- Offer an efficient periodic update schedule after successful install or refresh.
What it can do on your machine
Read from SKILL.md and the folder at commit d9a1696. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
npxgorg
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
Printing Press Library loads about 4.8k tokens when it runs. Until then it costs about 52 tokens; SKILL.md has 2,446 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 passed
The automated check found no risky patterns in SKILL.md.
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.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 2,446 words (~4,839 tokens).
