AGENTS.md

claude-seo-geo AGENTS.md is an instructions file for Claude Code, Codex, OpenCode from Thibaultbm/claude-seo-geo. It costs 755 tokens per session, scanned A, original, MIT.

A set of search-engine optimisation instructions and skills for coding agents. It is written in plain Markdown so different agent tools can use the same guidance.

In plain words
What is it for?
It helps configure SEO work in Claude Code, Cursor, Codex, Gemini CLI, Cline, Aider, and similar tools, including audits and page-section checks.
Why use it?
It avoids rewriting the same SEO instructions for each coding agent. It also explains when to load supporting reference files.

Written for Claude Code and Codex and OpenCode: Claude Code plugin machinery, but also the file is AGENTS.md. Also seen: reads .claude/ paths; mentions Claude Code; mentions AGENTS.md.

This is Thibaultbm/claude-seo-geo's own configuration. It tells Claude Code, Codex and OpenCode how to work on claude-seo-geo 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 claude-seo-geo 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

claude-seo-geo AGENTS.md 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 9d 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 — 51 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Using these skills outside Claude Code

Every skill in this repository is plain markdown that follows the open Agent Skills format (https://agentskills.io). Nothing here depends on Claude Code internals, so the same files work in any agent that can read instructions from disk.

Claude Code

Install as a plugin (recommended):

/plugin marketplace add Thibaultbm/claude-seo-geo
/plugin install claude-seo-geo@sorank

Or copy skills manually:

git clone --depth 1 https://github.com/Thibaultbm/claude-seo-geo.git
cp -r claude-seo-geo/skills/* ~/.claude/skills/

Cursor, Codex, Gemini CLI, Cline, Aider and others

  1. Clone the repository somewhere stable.
  2. Point your agent at the skill you need: paste the relevant SKILL.md into context, or reference its path in your rules file (.cursorrules, AGENTS.md, GEMINI.md, etc).
  3. The references/ files inside each skill are meant to be loaded on demand: load them when the SKILL.md says so, not upfront.
  4. The executables in the repository are skills/seo-geo-audit/scripts/seo_audit.py, skills/seo-page-sections/scripts/section_audit.py, skills/seo-ai-site-builders/scripts/render_check.py, skills/seo-traffic-drop/scripts/gsc_diff.py, and the two vault-audit scripts in skills/obsidian-brain/scripts/ (link_graph.py, person_matches.py). All are pure Python standard library (Python 3.9+), read only, no packages to install, no API keys.

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.
