graph-engineer: Instructions file for Codex

AGENTS.md

graph-engineer AGENTS.md is an instructions file for Codex, OpenCode from Ranteck/graph-engineer. It costs 2,626 tokens per session, scanned A, original, MIT.

A repository guide for the graph-engineer Codex skill, a reusable set of instructions for guiding engineering work. The repository contains the skill and its reference documents, not an application.

In plain words
What is it for?
Use it when maintaining or applying the graph-engineer skill. It helps with its eight-part work cycle, scenario templates, quality checks, review options, and source references.
Why use it?
It explains the repository’s structure, terminology, design rule, and relationship between the main instructions and README, reducing the chance of editing the wrong material.

Instructions file for CodexOpenCode

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

This is Ranteck/graph-engineer's own configuration. It tells Codex and OpenCode how to work on graph-engineer 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 graph-engineer 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 A, and why

graph-engineer 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.

What this repository is

This repo's main artifact is a Claude Code skill package named graph-engineer, which uses Codex as its default implementation and review worker. There is no application code, build step, application test suite, or package manifest. The skill lives here; supporting documentation, validation hooks, and cycle state also exist in the repository:

skills/graph-engineer/
├── SKILL.md                       # the skill's instructions (source of truth)
└── references/
    ├── goal-templates.md              # ready-to-use /goal templates per scenario
    ├── quality-gate-detection.md      # generic quality-gate command resolver algorithm
    ├── elevated-assurance.md          # optional opt-in multi-lens CRITIQUE variant
    ├── backend-selection.md           # opt-in per-cycle writer/reviewer routing
    ├── context-lifecycle.md            # scoped feature context, round history, and archival
    └── sources.md                     # provenance: what's official Anthropic/OpenAI vs. not

Below, SKILL.md means skills/graph-engineer/SKILL.md; reference-file basenames such as sources.md mean files in skills/graph-engineer/references/.

README.md at the repo root is the human-facing explanation of the same skill and must stay consistent with skills/graph-engineer/SKILL.md — they describe the same 8-node cycle from two angles (marketing/usage vs. operational instructions). When editing one, check whether the other needs a matching update (e.g. node numbering, flag names, the anti-loop cutoff wording). Their section order is deliberately different, though: README.md is ordered for reading (what is this → what does the cycle look like → how do I use it → what can go wrong), while SKILL.md is ordered for execution (node 0 through node 7 in sequence). Don't treat a reordering of one as something that needs mirroring in the other — only the claims need to match, not the layout.

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.
