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 | $0.00087 | $0.01667 |
| Opus 5 | $0.00044 | $0.00834 |
| Sonnet 5 | $0.00017 | $0.00333 |
| Haiku 4.5 | $0.00009 | $0.00167 |
Grade C, and why
website-deploy scanned grade C with 2 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 yesterday.
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.

curl | sh runs whatever the server returns today, which is not necessarily what it returned when this was reviewed.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

The opening of the file, as written. The whole thing — 124 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Website Deploy
Website Deploy hosts static websites on simple-host.app. There is no server-side execution, but every site gets a small server-backed backend (shared JSON state, append-only collections) that its own page JavaScript can call.
Service
- API and dashboard:
https://simple-host.app - Auth header on every authenticated call:
X-API-Key: <api_key> - Version header on every API call:
X-Skill-Version: 0.11.0. Always send it. The server only flags an update when it is genuinely newer than this; omit the header and it will tell you to update on every call (a reinstall loop). - Config file:
~/.website-deploy/config.json— resolve~to the OS home directory yourself ($HOMEon macOS/Linux,$env:USERPROFILEin PowerShell,%USERPROFILE%only incmd). Some tool-call paths do not expand a literal~. - OpenAPI reference:
/docs.html
The one rule that breaks sites: use relative links
Every site is served from a path on a shared content host:
https://sites.simple-host.app/<handle>/<sitename>/
handle is the owner's URL-safe handle (from GET /v1/me). Because the site
lives under a path prefix, a root-absolute URL like /css/app.css resolves off
the site and 404s. Use css/app.css, ./img/x.png, ../shared/y. For framework
builds, set the base/public path so the output emits relative URLs.
Older https://<sitename>.simple-host.app/ links still resolve (legacy).

Read the whole file before acting. If the file is not on disk next to this one —
some install methods fetch only SKILL.md — fetch the URL instead.

What ships with it
5 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.

website-deploy is a skill published in the GitHub repository vineetu/simple-host (1 stars, last pushed 2d ago), licensed MIT. It adds 87 tokens to every session and 1,667 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
