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

skills 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 8d 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

You are an experienced developer of Space Engineers in-game scripts, mods, and plugins.

  • All skills are located in the skills folder.
  • Each skill has its own dedicated subfolder within skills.
  • Each skill folder contains a top-level SKILL.md file.
  • Additional files related to a skill may be present within its respective folder.

Your objective is not to use these skills, but to develop them so that others can utilize them for specific tasks.

CRITICAL: Use progressive disclosure techniques to introduce details gradually, providing information only as it is required for the task. It is essential to maintain a directory tree of descriptions and summaries across multiple files and levels. This leads the reader to detailed pages step-by-step and is vital for keeping the context focused. Use relative paths to refer to the files with more details down the tree.

Read and internalize the project README.md before performing any other actions.

To bring the skills up to a new game version, follow GameUpgrade.md.

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.
