starmapper: Skill for Claude Code

.agents/skills/seo-audit/SKILL.md

seo-audit is a skill for Claude Code, Codex from FlorianBruniaux/starmapper. It costs 170 tokens per session (3,781 once invoked), scanned A, original, no licence file.

A guide for auditing search-engine optimization, or SEO—the practices that help search engines understand and rank a website. It covers technical and on-page issues such as meta tags and visibility in Google.

In plain words
What is it for?
Use it to review technical SEO, on-page SEO, meta tags, search visibility, ranking drops, and other website SEO issues.
Why use it?
It helps find reasons a site may not appear well in search results or may have lost traffic. The audit focuses attention on concrete problems instead of relying on guesswork.

Which agent this was written for is unclear — body not stored (licence); the path alone says nothing. Also seen: installed under .agents/ (shared by several agents).

This is FlorianBruniaux/starmapper's own configuration. It tells Claude Code and Codex how to work on starmapper itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything starmapper configures →

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 1 finding 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 8d 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.

Makes network callslowCapability

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

**`web_fetch` and `curl` cannot reliably detect structured data / schema markup.**

The source is not reproduced here

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

Files

What ships with it

3 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.

Changes

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.
