In plain words
What is it for?
Use it when adding or updating a Scenario skill, its tests, supporting references, or public documentation.
Why use it?
It clarifies the repository layout and authoring rules, helping contributors publish skills that agents can find and follow correctly.

Written for Claude Code and Codex and OpenCode: SessionStart hook event, but also the file is AGENTS.md. Also seen: reads .claude/ paths; mentions .claude-plugin; mentions CLAUDE.md.

This is scenario-labs/skills's own configuration. It tells Claude Code, Codex and OpenCode how to work on skills 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 skills configures →

About the project

Scenario Agent Skills is a collection of instructions that teaches AI coding agents to create images, video, audio, textures, skyboxes, and 3D assets through the Scenario MCP server, an interface to Scenario’s generation tools and custom-trained models. It serves game, entertainment, marketing, and other creative work, and also includes workflows for digital content creation software and game engines. The catalogue entries are these skills, along with plugins, commands, agents, instructions, settings, and hooks for using Scenario or driving supported creative applications.

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 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 5d 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.

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

What this repo is

Public Agent Skills for Scenario: procedural knowledge that teaches AI coding agents to create production-ready content through the Scenario MCP server. The content spans images, video, audio, textures, skyboxes, 3D, and custom models, for games, entertainment, and any creative vertical.

  • Format: Agent Skills.
  • Install: npx skills add scenario-labs/skills.
  • Listing: skills.sh.
  • The one exception to the MCP focus: the expert tools, teams of skills that drive DCC software and game engines installed on the user's machine (see Expert tools).

Quick start

  • pnpm install: once after cloning. It installs the git hooks.

  • pnpm format && pnpm validate: before committing. format rewrites files locally; validate runs the checks CI runs, format:check included.

  • pnpm test: after touching a script. Through uv, each Python suite gets the packages its tests/<name>/requirements.txt lists.

  • /skills:validate <name> ($skills-validate in Codex): the application test, before merging a skill change.

Layout

skills/<name>/SKILL.md                         # name must equal the directory name
skills/<category>/<family>/README.md           # expert tools: the family's build notes
skills/<category>/<family>/<name>/SKILL.md     # expert tools: dcc/ or game-engines/
tests/<name>/                                  # test suite for any script shipped with skill <name>
  • scripts/lib/skills.mjs defines this layout, and every check finds skills through it.
  • Skill names are unique repo-wide (pnpm skill-files checks). The skills CLI installs every skill flat under its name, whatever its folder, and silently keeps only the first of two that share one.
  • A supporting file (heavy reference, script) sits next to a SKILL.md only when its content is too large to inline.
  • Link every supporting file directly from SKILL.md. Agents resolve file references one level deep, so a file reached only through another may never be read.
  • A skill may carry a README.md recording how it was built and why it makes its choices. It is for the agents and humans working on the skill, not the agent running it.
    • It is the one supporting file exempt from the link rule (pnpm skill-files skips it).
    • Leave it unlinked: linking it spends body words and invites a runtime agent to read maintainer notes as instructions, which once made an agent discount a fact it needed.
  • Every script shipped with a skill has a test suite in tests/<name>/ at the repo root, never in the skill directory: a published skill directory carries only what an agent needs at runtime. See Validation and testing.

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.
