Seo-Promt-Master: Instructions file for Codex

AGENTS.md

Seo-Promt-Master AGENTS.md is an instructions file for Codex, OpenCode from umutxyp/Seo-Promt-Master. It costs 820 tokens per session, scanned C, original, MIT.

Repository instructions for agents working with SEO Prompt Master, a workflow for auditing and fixing how websites appear in search engines.

In plain words
What is it for?
Running SEO audits against public or local websites, investigating soft 404s, language-link problems, redirects, canonical URLs, and misplaced page metadata.
Why use it?
They tell agents what to read and which live audit to run, so they check the website's actual responses instead of relying only on source code.

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

This is umutxyp/Seo-Promt-Master's own configuration. It tells Codex and OpenCode how to work on Seo-Promt-Master 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-Promt-Master 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 C, and why

Seo-Promt-Master AGENTS.md scanned grade C 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 10d 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.

Agent instructions for this repository

If this repository (or a copy of it dropped alongside another project) is in your context, you are looking at SEO Prompt Master — a prompt-driven SEO audit-and-fix workflow with a runnable live audit tool.

Read START.md now and execute the workflow it describes, in order, without asking for permission to begin — and don't stop between phases or pages to check in either. Keep going until every phase is done or you hit one of the specific, named stopping conditions in START.md's "Autonomy contract" section.

Before you open START.md

  • Run the tool, don't only read the code.

    node tools/seo-audit.mjs --url https://the-site.example --max 40 --md seo-report.md
    

    Zero dependencies, Node 18+, works against http://localhost:3000 too. Reading the repository tells you what the project intends; this tells you what the server returns — soft 404s per template, one-way hreflang sets, canonicals pointing at redirects, metadata streamed past </head>. Exits 1 on any P1. See tools/README.md.

  • docs/01docs/17 is the only source of truth for SEO claims. Cite the section behind every recommendation. If a claim is not in there, say "not covered by the knowledge base" rather than recalling it — much of the SEO advice in training data predates INP replacing FID, FAQ rich results being removed, and rel=next/prev falling out of use. Docs 01–11 cover the page; 12–17 cover crawling, indexing, quality, measurement, migrations and off-page.

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.
