seohead-seotools: Instructions file for Codex

AGENTS.md

seohead-seotools AGENTS.md is an instructions file for Codex, OpenCode from PavloSEO/seohead-seotools. It costs 1,022 tokens per session, scanned A, original, MIT.

A set of project instructions for SEOHEAD Tools, a local command-line and local agent-server toolkit that checks website data and builds audit reports.

In plain words
What is it for?
It helps agents work safely on the SEOHEAD codebase, use Screaming Frog exports correctly, preserve failed or skipped checks, and produce audit, task, and report files.
Why use it?
It gives coding agents the repository’s rules, architecture, and limits so they do not add unsupported interfaces or treat the tool as a website crawler.

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

seohead-seotools 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 7d 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 — 93 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENTS.md — public repository contract

SEOHEAD Tools is a headless, local-first evidence and audit-automation layer for SEO specialists and tool-calling agents. It has exactly two user interfaces: the seohead CLI and one local stdio MCP server. Do not add a GUI, desktop shell, hosted API, or remote MCP endpoint to this repository.

Product model

Do not present SEOHEAD as a replacement for Screaming Frog or as a collection of unrelated scripts. The crawler and this toolkit have different jobs:

  • Screaming Frog produces the CSV/XLSX exports consumed by SEOHEAD's 96-check analyzer. Do not imply that another crawler's exports are drop-in compatible.
  • SEOHEAD analyzes those SF exports, adds bounded live and infrastructure evidence, preserves skipped/failed measurements, and produces structured audit, task, and report artifacts.
  • The CLI and MCP expose the same tested core so either a specialist or an AI agent can run the workflow without improvising its own crawler.
  • Skills guide orchestration and interpretation; they are not evidence sources, and final judgement remains with the specialist.

Live SF mode launches a separately installed, actively licensed Screaming Frog CLI. Export mode works from existing CSV/XLSX files. The site-audit command is a bounded sitemap-based pass, not an exhaustive run of the tool catalog and not a general-purpose crawl.

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.
