seo-graph AGENTS.md

Instructions for seo-graph, a TypeScript library that builds linked Schema.org JSON-LD graphs for search engines and other software. JSON-LD is a machine-readable way to describe page content, while Astro is a web framework supported by one of its packages.

In plain words
What is it for?
Building typed SEO entities, combining them into a deduplicated graph, adding SEO data to Astro pages, and exposing schema endpoints or content helpers.
Why use it?
It avoids hand-writing inconsistent or invalid structured data and explains which Schema.org entities fit common website types.

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

seo-graph 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 yesterday.

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.

AGENTS.md — seo-graph

This file is for AI coding agents (Claude Code, Cursor, Copilot, etc.) building sites that use @jdevalk/seo-graph-core and/or @jdevalk/astro-seo-graph. It explains what the library does, how the pieces fit together, and which schema.org entities to use for every common site type.

What this library does

seo-graph builds valid, linked schema.org JSON-LD @graph arrays from typed inputs. Instead of hand-writing JSON-LD (error-prone) or copying snippets from schema.org docs (inconsistent), you call piece builders that return strongly-typed entities, then wrap them in a @graph envelope.

Two packages:

  • @jdevalk/seo-graph-core — Pure TypeScript, no framework dependency. Piece builders, ID factory, graph assembler, deduplication. Use this from any runtime.
  • @jdevalk/astro-seo-graph — Astro integration. <Seo> component, route factories for schema endpoints, schema map for agent discovery, Zod content helpers.

Contents

Schema core — concepts and builders for the JSON-LD graph:

Recipes and patterns — how to model real sites:

Astro integration — runtime component and build-time checks:

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.
