argentum-engine: Skill for Claude Code

.agents/skills/generate-scenario/SKILL.md

generate-scenario is a skill for Claude Code, Codex from wingedsheep/argentum-engine. It costs 31 tokens per session (1,886 once invoked), scanned B, original, no licence file.

A generator for test-scenario JSON files used by the DevScenarioController. You describe the behaviour you want to test, and it produces a scenario file in the required format.

In plain words
What is it for?
Use it to create scenarios for testing specific game situations in Argentum Engine.
Why use it?
It removes the need to learn and write the scenario JSON structure by hand. This makes it easier to set up repeatable development tests.

Skill for Claude CodeCodex

Written for Claude Code: argument-hint in frontmatter. Also seen: installed under .agents/ (shared by several agents).

This is wingedsheep/argentum-engine's own configuration. It tells Claude Code and Codex how to work on argentum-engine 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 argentum-engine 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 B, and why

generate-scenario scanned grade B with 2 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 9d 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.

Sends data to an external URLmediumData exfiltration

A POST to an outside endpoint may be telemetry or may be exfiltration; either way the mod talks to somewhere, and you should know where.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

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.
