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 5.1 | $0.01550 | $0.01550 |
| Opus 5 | $0.00775 | $0.00775 |
| Sonnet 5 | $0.00310 | $0.00310 |
| Haiku 4.5 | $0.00155 | $0.00155 |
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.
How it starts
The opening of the file, as written. The whole thing — 100 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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.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:

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.
