supergraph: Instructions file for Codex

AGENTS.md

supergraph AGENTS.md is an instructions file for Codex, OpenCode from datit309/supergraph. It costs 2,933 tokens per session, scanned A, original, MIT.

Repository rules for Supergraph, including a required workflow and named skills for different coding tasks. They guide an agent from scanning and planning through testing, integration, verification, and review.

In plain words
What is it for?
Use them when working on Supergraph features, fixes, refactors, diagnosis, testing, or reviews.
Why use it?
They make the expected development process explicit, especially when a change needs tests or touches unfamiliar code.

Instructions file for CodexOpenCode

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

This is datit309/supergraph's own configuration. It tells Codex and OpenCode how to work on supergraph 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 supergraph 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

supergraph 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 today.

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.

Supergraph — Mandatory Workflows

CRITICAL: These are MANDATORY. Not suggestions. Not optional. Every coding task MUST follow this process.


Skills

This project uses supergraph skills:

  • Claude Code & Codex: invoke with /supergraph: prefix (e.g. /supergraph:scan, /supergraph:plan).
  • DeepSeek Harness (DSH) & OpenCode: invoke bare skill names without prefix (e.g. /scan, /plan, /tdd, /verify, or via tool skill(name="scan") on DSH). DSH skill names follow /^[a-z0-9]+(?:-[a-z0-9]+)*$/ and do not use colons. Your AI agent MUST read and follow the relevant skill before each phase.
Skill (Claude/Codex) Skill (DSH/OpenCode) When to read

Changes

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.
