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

graph-engineering-crash-course 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 1mo 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 — 77 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENTS.md

Operating rules for any agent — human-directed or autonomous, Claude Code, OpenCode, or anything else — that touches this repository. These rules apply regardless of which tool is doing the work. If you are looking for tool-specific notes, see CLAUDE.md; the rules below sit underneath it and take priority whenever the two seem to disagree.

1. graph-plan.md is the master spec, and it is human-only

graph-plan.md is the single source of truth for what this course is and how it is built. No agent, loop, or automated process may edit it. It changes only by direct action of the human owner of this repository. If a plan, a page, or a piece of tooling seems to conflict with graph-plan.md, the plan wins and the conflict gets flagged for the human to resolve — the fix is never to quietly bring the spec in line with whatever the agent already did.

The same protection covers the source table in resources/sources.md: the ten entries there (see below) are load-bearing attribution records, not editorial copy, and no automated process may add to, remove from, or reword that table.

2. The originality policy is not optional

Every docs/ page in this course is written from a contributor's own understanding of an idea, never with a source page open next to the editor and never as a light rewording of someone else's sentences. This isn't a style preference — it's mechanically enforced. Before any docs/ change is committed, scripts/originality-check.mjs must run clean. The full policy, including the quoting exception for the one attributed statement in this course, lives in graph-plan.md §2.1; the record of exactly which idea came from which of the ten sources, and why it earned a place here, lives in resources/sources.md. An agent that cannot make a page pass the originality check should stop and rewrite from a blank page, not fight the checker with synonym substitution — synonym-swapped plagiarism is still plagiarism, and the checker is not the only line of defense; a human reviewer reads for it too.

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.
