seo-skills-ai: Instructions file for Claude Code

AGENTS.md

seo-skills-ai AGENTS.md is an instructions file for Claude Code, Codex, OpenCode from seoskillsai/seo-skills-ai. It costs 1,550 tokens per session, scanned A, original, MIT.

Shared instructions for SEO tools that work across many coding assistants and editors. SEO means improving how pages are understood and found by search engines.

In plain words
What is it for?
Use them when running SEO skills across different agent tools, checking compatibility, or understanding where each tool discovers its instructions and reusable skills.
Why use it?
They reduce differences between tools such as Claude Code, Cursor, and Gemini CLI by explaining how each one loads the same skills and instructions. They also provide a way to check whether the skills remain portable.

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

This is seoskillsai/seo-skills-ai's own configuration. It tells Claude Code, Codex and OpenCode how to work on seo-skills-ai 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 seo-skills-ai 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.

ModelPer sessionOnce invoked
Fable 5.1 $0.01550 $0.01550
Opus 5 $0.00775 $0.00775
Sonnet 5 $0.00310 $0.00310
Haiku 4.5 $0.00155 $0.00155

Security

Grade A, and why

seo-skills-ai 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 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.

SEO Skills AI: Universal Multi-Platform Agent Instructions

Applies to: Anthropic Claude Code, Google Antigravity IDE, Gemini CLI, Cursor IDE, Windsurf Cascade, OpenAI ChatGPT / Codex CLI, Cline, Roo Code, Aider CLI, Grok Build, DeepSeek R1, and Nous Hermes Agent.

Claude Code CLI users: see CLAUDE.md.


1. Universal Cross-Platform Portability

Every skill in skills/*/SKILL.md is authored to the open Agent Skills specification. This repository is 100% harness-agnostic.

Agent Harness Loading Directives

AI Agent Harness How to Load & Execute SEO Skills AI
Google Antigravity & Gemini CLI Point workspace at repository root. Antigravity reads AGENTS.md automatically and auto-discovers all skills in skills/.
Cursor IDE Reads .cursorrules from root. Skills are auto-discovered from skills/ or symlinked to .cursor/rules/.
Windsurf Cascade Reads .windsurfrules from root. Cascade flows execute multi-file refactoring and sitemap generation.
Anthropic Claude Code Auto-discovered via .claude-plugin/plugin.json or invoked via /seo [command].
OpenAI ChatGPT / Codex CLI Reads AGENTS.md at root. Custom Actions utilize config/openapi-schema.json.
Cline & Roo Code (VS Code) Loads AGENTS.md from root. MCP tools are configured in config/cline_mcp_settings.json.
Aider CLI Reads AGENTS.md from root. Review generated SEO diffs before applying; do not auto-commit patches.
DeepSeek R1 / Local Ollama Contextually ingest skills/{skill}/SKILL.md for zero-token-cost local execution.

2. Universal Tool-Name Mapping

Where skills reference tool execution commands, each harness maps them transparently:

Action Claude Code Codex / ChatGPT Cline / Roo Code Cursor / Antigravity Aider
Read File Read read_file read_file read / view_file inline
Write File Write write_file write_file write / write_to_file /add then edit
Edit Block Edit apply_diff replace_in_file edit / replace_file_content /edit
Run Command Bash bash execute_command shell / run_command /run
Grep / Search Grep grep search_files grep / grep_search /grep
Find Files Glob glob search_files find / find_by_name inline
Fetch Web WebFetch fetch browser_tool fetch / read_url_content inline

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.
