In plain words
What is it for?

Why use it?
It shows what may be reducing search visibility without inventing scores or relying on assumptions. It also makes clear which checks could not be completed.

About the project

StarNet is a local-first desktop harness for creating AI agents and arranging them in a pixel-art space station whose layout represents their capabilities, permissions, and workflow. It lets people run real model calls and tools through multiple bounded agents, using their own provider keys or accounts and optionally messaging the station through chat services. The catalogue entries are skills that extend or support work performed by StarNet agents.

Getting it into your agent

Token cost

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.

Security

Grade A, and why

seo-audit 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 12d 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.

The opening of the file, as written. The whole thing — 135 lines — stays where its author put it; the contents beside it link to each section on GitHub.

SEO Audit

Find what is stopping a site from being found in search, and say what to fix first. The bar: every finding names the URL and what you actually saw there, and every check you could not run is listed as not run. No guessed scores, no findings from memory.

When to use

  • "Audit my site's SEO." "Why am I not ranking?" "My traffic dropped."
  • A technical check before or after a redesign or a migration.
  • A review of titles, headings and content on named pages.

Not for writing a new page (landing-copy), planning what to publish (content-calendar), or raising sign-ups on a page that already gets visitors (conversion-review).

How you read a site, and what each tool cannot see

You need Use Blind spot
robots.txt, sitemaps, page copy (usually with its headings marked) web_fetch Cleaned text only. Scripts are dropped, so structured data never shows, and long files are cut short.
The first H1 as rendered browser.get_text with the selector h1 First match only.
The page as a visitor's browser builds it browser.navigate, then browser.get_text Visible text only.
Structured data (JSON-LD) browser.get_text with the selector script[type="application/ld+json"] Returns the first matching block. If the raw HTML shows more blocks, read them there.
The page title as rendered browser.get_text with the selector title None.
Raw <head> (meta description, robots meta, canonical, hreflang), HTTP status, redirects web_request with method GET or HEAD Returns the status and the start of the raw response. Tags a script adds after load are not in it.
What loaded, what failed, how heavy it was browser.network One lab visit, not real-visitor speed.
What the page looks like browser.screenshot The current viewport only.

Never report "no structured data" from web_fetch or raw HTML alone. Many sites add it with a script after the page loads. Only the rendered page settles it. If your tool list has a browser tool that runs a page expression (look with tool.search), use it to list every JSON-LD block and the rendered canonical and robots tags.

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.
