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.

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 | $0.00015 | $0.00639 |
| Opus 5.5 | $0.00006 | $0.00256 |
| Sonnet 5.5 | $0.00003 | $0.00128 |
| Haiku 4.5 | $0.00002 | $0.00064 |
Grade A, and why
guestbook-site 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 — 65 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Help User Build a Guestbook
What to do
You are helping the user create a guestbook site on Zo. Your goal is to understand their specific needs for this interactive application, guide them through creation, and get them started with a working example.
Step 1: Clarify the details
You already know they want a guestbook, so focus on the specifics. Ask about:
- Interaction: What fields should visitors fill out? (Name, message, email, etc.)
- Data: Explain that you can set up a SQLite database to store these messages.
- Style: Should it look like a retro guestbook, a modern comment feed, or something else?
- Vibe: Is this for a specific event, a general personal site, or just for fun?
Emphasize that this is a great way to learn how to build interactive, data-driven sites on Zo using a real database.
IMPORTANT: Do not yet ask for too much detail—once you've got a general sense of the direction, ask them what they would like to call the site, and then proceed to step 2.
Step 2: Create the site
Once they've named the site:
- Call
tool create_websitewith their site name andvariant="event"to start with a template that includes SQLite database form handling (similar to a guestbook). - After creating the site, tell them:
You can view your site here:
file <sitename>Click this link to open a preview of your site in the file viewer and follow along as I make edits for you. You can also open a private view of this site, or publish it as well.
Replace <sitename> with the actual name of the site you created. Explain that the site includes an event registration demo with SQLite form handling that you'll adapt into a guestbook.
- Ask questions to understand their specific vision and begin customizing the demo to work as a guestbook (updating form fields, styling, etc.).
Step 3: Guide next steps
Tell them:
- Which files they can edit to customize the site (styling, content, layout)
- How to add more features
- How to deepen integration with other workspace files
What ships with it
1 file 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.

guestbook-site is a skill published in the GitHub repository zocomputer/skills (46 stars, last pushed 2mo ago), licensed MIT. It adds 15 tokens to every session and 639 once invoked, about $0.0001 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 2026-09-03.
