onboard

A step-by-step guide for adding a new fusion facility to IMAS Codex. A fusion facility is a site or device used for nuclear-fusion research; the description does not explain what IMAS Codex is.

In plain words
What is it for?
Use it when onboarding a new fusion facility into IMAS Codex.
Why use it?
It provides instructions for this specialised setup instead of leaving the steps to be discovered from scratch.

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 B, and why

onboard scanned grade B with 1 finding 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 2d 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.

Asks for rootmediumPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

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.

onboard is an agent published in the GitHub repository iterorganization/IMAS-Codex (8 stars, last pushed 3mo ago), with no licence file. It costs nothing until one of its globs matches a file; then it loads 2,678 tokens. A static security scan graded it B with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
