Server-OS: Instructions file for Codex

AGENTS.md

Server-OS AGENTS.md is an instructions file for Codex, OpenCode from ANAMIZED/Server-OS. It costs 300 tokens per session, scanned A, original, no licence file.

A project guide for coding agents working on ANAMIZED/Server-OS. It explains what the project is, how to run and check it, and which rules and working parts must be preserved.

In plain words
What is it for?
Use it when asking an agent to change, run, verify, or understand the Server-OS codebase.
Why use it?
It gives an agent the project context and checks it needs before making changes. This reduces the risk of breaking required behavior or ignoring project rules.

Instructions file for CodexOpenCode

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

This is ANAMIZED/Server-OS's own configuration. It tells Codex and OpenCode how to work on Server-OS 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 Server-OS 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

Server-OS 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 2mo 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.

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

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.
