AGENTS.md

AgentOS AGENTS.md is an instructions file for Codex, OpenCode from SapienXai/AgentOS. It costs 1,517 tokens per session, scanned A, original, MIT.

Repository instructions for keeping AgentOS as the user-facing layer over OpenClaw, the system that runs and coordinates agents and tools.

In plain words
What is it for?
Use them when changing AgentOS code, its interface, OpenClaw connections, authentication, releases, publishing, or other security-sensitive areas.
Why use it?
They prevent duplicate backend work and keep code, language, security, and release changes aligned with the project’s required guidance.

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

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

AgentOS 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.

AGENTS.md

Project Identity

AgentOS is the human operating layer above OpenClaw.

OpenClaw is the backend, runtime, orchestration, agent, tool, model, session, and gateway layer. AgentOS must not clone or replace OpenClaw. AgentOS should provide the operator-facing workspace, control, visibility, policy, and coordination layer on top of OpenClaw.

When in doubt:

  • Use OpenClaw as the source of truth.
  • Keep AgentOS as the control/UI/application layer.
  • Do not duplicate OpenClaw backend functionality inside AgentOS.

Required Project Skill

Before making AgentOS code, UX, OpenClaw integration, security, release, or publishing changes, read:

docs/agentos-codex-skill.md

Keep all changes aligned with that skill.

If the task touches OpenClaw, releases, npm publishing, GitHub releases, auth, accounts, model credentials, API routes, local operator access, browser profiles, or security-sensitive behavior, the skill file is mandatory context, not optional background.

Project Language

  • The project’s default language is English.
  • Do not add Turkish content to the project unless the user explicitly asks for it.
  • Keep user-facing copy in English, including UI text, placeholders, examples, documentation, seeded content, errors, empty states, release notes, and CLI output.
  • Internal comments should also be English unless there is a strong reason otherwise.

Git

  • All git commit messages must be written in English.
  • Use concise, imperative commit subjects.
  • Prefer Conventional Commits format, for example: feat(auth): add session refresh.
  • Keep the subject line short, ideally under 72 characters.
  • Default to a single-line commit message.
  • Only add a commit body when extra context is genuinely necessary.
  • If a body is needed, keep it brief and focused on why the change was made.
  • Do not generate long commit messages or file-by-file summaries by default.
  • Do not write commit messages in Turkish unless the user explicitly asks for it.

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.
