os-init

A command that starts a guided setup conversation for an Agentic OS in a project. It discovers project needs and creates structures such as instruction files and a context folder.

In plain words
What is it for?
Use it to gather requirements, plan the needed components, and bootstrap the project's agent instructions and context files.
Why use it?
It gives a new project an organized starting point for working with coding agents instead of requiring the setup to be designed manually.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

os-init 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 3d 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.

What it actually says

/os-init Command

Please invoke the agentic-os-setup agent immediately. You will act as an orchestration guide to discover the project requirements, plan the exact components needed, and iteratively bootstrap the Agentic OS (CLAUDE.md hierarchy, context folder, etc.) inside this repository.

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.
