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
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00096 | $0.00942 |
| Opus 5.5 | $0.00038 | $0.00377 |
| Sonnet 5.5 | $0.00019 | $0.00188 |
| Haiku 4.5 | $0.00010 | $0.00094 |
Grade A, and why
printing-press-retro 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 1mo 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 — 82 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/printing-press-retro
Result: A scrubbed retro document and, when the issue gate passes, GitHub issues for Printing Press defects only.
Next consumer: A maintainer or agent who will change the Printing Press (generator, scorer, skills, or binary) — not the printed CLI that just shipped.
Done: The manuscript proof exists and is scrubbed; every work unit is file-new, comment-on-existing, or local-only; no unredacted secret or PII remains; the user has the outcome list.
Intent: "Raised the floor" is analysis language, not a filing bar. File only when the Printing Press must change to stop a current, reproducible, generalizing P1 or P2 defect. Manual iteration on one CLI is expected work, not a finding. In user-facing output say "the Printing Press"; name the subsystem when pointing at a fix.
Boundaries
- Redact every real secret and PII before quoting. Issue bodies and retro docs are public. Use references/secret-scrubbing.md Layer 0. Never quote a leaked value as evidence of the leak.
- Don't change the machine by default. The burden of proof is on the finding.
- No P3. File only P1/P2. Anything else is Skip or Drop, not a low-priority issue. The issue gate files P1/P2 Do work units only.
- Never upload unscrubbed artifacts. Never modify manuscript or library source trees; scrub copies only.
Authority
Invocation authorizes reading manuscripts/library and writing the retro proof plus scratch copies. It does not authorize GitHub filing or public upload until the user confirms Submit. It does not authorize edits to the printed CLI or to Printing Press source.
Steps
Read references/run-resolution.md first. It
resolves $API_NAME, $RUN_ID, $RUN_DIR, $CLI_DIR, and $IN_REPO.
Never execute a phase from memory. When you enter a phase, Read its file from phases/ first.
What ships with it
13 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-retro is a skill published in the GitHub repository mvanhorn/cli-printing-press (4,848 stars, last pushed today), licensed MIT. It adds 96 tokens to every session and 942 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.
