NoaCG-Studio: Instructions file for Codex

AGENTS.md

NoaCG-Studio AGENTS.md is an instructions file for Codex, OpenCode from NoaCG/NoaCG-Studio. It costs 675 tokens per session, scanned A, original, AGPL-3.0.

An `AGENTS.md` instruction file for the NoaCG-Studio project that tells coding agents how to load and update folder rules.

In plain words
What is it for?
Use it when an agent is working in NoaCG-Studio and needs to load rules before editing or change a rule through the project's learning command.
Why use it?
It keeps project rules tied to their source contracts instead of encouraging direct edits to the generated instruction file.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md.

This is NoaCG/NoaCG-Studio's own configuration. It tells Codex and OpenCode how to work on NoaCG-Studio 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 NoaCG-Studio 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

NoaCG-Studio 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.

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.
