agents-md-generator: Instructions file for Codex

AGENTS.md

agents-md-generator AGENTS.md is an instructions file for Codex, OpenCode from nguyenthedat123/agents-md-generator. It costs 939 tokens per session, scanned A, original, MIT.

Repository instructions for AI coding agents, saved in an AGENTS.md file. They describe the project, how to set it up, common commands, its folders, and rules for making changes.

In plain words
What is it for?
Use it to document a JavaScript and Node.js project, including its npm commands, test command, source folders, and continuous-integration files.
Why use it?
An unfamiliar coding agent can understand the repository's conventions and checks before editing files. This reduces repeated explanations and avoidable mistakes.

Instructions file for CodexOpenCode

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

This is nguyenthedat123/agents-md-generator's own configuration. It tells Codex and OpenCode how to work on agents-md-generator 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 agents-md-generator 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

agents-md-generator 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 9d 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.

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.
