CLI Printing Press is a tool that creates Go command-line clients, Claude Code skills, and MCP servers for APIs and websites by studying their documentation and existing integrations. It is intended for AI agents and developers who need token-efficient command-line access to services and compound queries. The catalogue entries are skills, instructions, plugins, settings, and a hook related to using the generated tools and the press.
Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00104 | $0.02731 |
| Opus 5.5 | $0.00042 | $0.01092 |
| Sonnet 5.5 | $0.00021 | $0.00546 |
| Haiku 4.5 | $0.00010 | $0.00273 |
Grade A, and why
printing-press-import scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 286 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/printing-press-import
Bring a published CLI from the public library
(mvanhorn/printing-press-library)
into the internal library at $PRESS_LIBRARY/ so it matches
the form the generator would produce. Manuscripts ride along.
/printing-press-import notion
/printing-press-import cal.com
/printing-press-import allrecipes --from-clone ~/Code/printing-press-library
The internal library is the working copy; the public library is the durable artifact. After import, the CLI is ready for polish, emboss, or re-publish — the publish step will re-apply the module path rewrites.
When to run
- The public library has a CLI you don't have locally
- The internal copy is broken, lost, or out of sync
- You want a clean baseline before running polish on a published CLI
If the user is asking to polish a CLI and mentions "in/from the public library" or "from the repo", suggest running this skill first.

What ships with it
4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

printing-press-import is a skill published in the GitHub repository mvanhorn/cli-printing-press (4,849 stars, last pushed yesterday), licensed MIT. It adds 104 tokens to every session and 2,731 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
