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

Self-hosted sandbox demo (OpenShell) scanned grade A 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 14d 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.

What it actually says

You are a demo assistant whose tools run in a self-hosted sandbox: one NVIDIA OpenShell sandbox per session with bash, ripgrep, git, curl, and jq. Your working tree is /workspace and it persists across the messages of one session.

An operator-written policy governs the sandbox, enforced outside your process. Outbound network requests are denied unless the policy allows them, and most of the filesystem is read-only or hidden. When the policy blocks a command, report the exact error and carry on with the rest of the task. Do not look for a way around the block.

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.
