What it does

Vmas Simulator Guide is an agent skill from wentorai/research-plugins. Vectorized multi-agent reinforcement learning simulator

Its SKILL.md is about 960 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in AI & LLM Engineering, covering Reinforcement learning and Multi-agent orchestration. The repository describes itself as: 350+ academic research skills, MCP configs, and plugins for Research-Claw and AI agents. The licence is MIT.

When your agent uses it

  • Tasks that involve Reinforcement learning
  • Tasks that involve Multi-agent orchestration

Example prompts

  • “/vmas-simulator-guide”

Requirements

  • Python 3

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. MARL research: Benchmark multi-agent algorithms
  2. Cooperative learning: Study emergent coordination
  3. Scalability testing: GPU-accelerated parallel training
  4. Custom scenarios: Design domain-specific multi-agent tasks
  5. Education: Teach multi-agent RL concepts

What it can do on your machine

Read from SKILL.md and the folder at commit bf44b3c. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • pip

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • github.com
    • arxiv.org

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Vmas Simulator Guide loads about 960 tokens when it runs. Until then it costs about 19 tokens; SKILL.md has 149 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~19
When it runs · the whole SKILL.md, loaded when a task matches
~960

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

VMAS: Vectorized Multi-Agent Simulator Guide

Overview

VMAS is a vectorized simulator for multi-agent reinforcement learning (MARL) that runs thousands of parallel environments on GPU via PyTorch. It provides a diverse set of 2D cooperative, competitive, and mixed scenarios for benchmarking multi-agent algorithms. Orders of magnitude faster than CPU-based simulators, enabling rapid research iteration on multi-agent coordination problems.

Installation

bash
pip install vmas

Quick Start

python
import vmas

# Create vectorized environment
env = vmas.make_env(
    scenario="simple_spread",
    num_envs=1024,         # Parallel environments
    num_agents=3,
    device="cuda",         # GPU acceleration
    continuous_actions=True,
)

# Environment loop
obs = env.reset()
for step in range(100):
    # Random actions for demonstration
    actions = [env.action_space[i].sample()
               for i in range(env.n_agents)]

    obs, rewards, dones, infos = env.step(actions)
    # obs: list of [num_envs, obs_dim] tensors
    # rewards: list of [num_envs] tensors

simple_tagCompetitive4Predator-prey
transportCooperative4Move package to goal
wheelCooperative4Coordination on wheel
flockingCooperative5+Reynolds flocking
discoveryCooperative3Explore and discover
navigationMixedNMulti-agent navigation

Integration with MARL Libraries

python
# With TorchRL
from torchrl.envs import VmasEnv

env = VmasEnv(
    scenario="simple_spread",
    num_envs=512,
    device="cuda",
)

# With RLlib
from ray.rllib.env import MultiAgentEnv
# VMAS provides RLlib-compatible wrapper

# With CleanRL / custom training
import torch

env = vmas.make_env("transport", num_envs=2048, device="cuda")
obs = env.reset()

# All tensors on GPU — train directly without CPU transfer
policy_output = policy_network(obs[0])  # Agent 0 observations

Custom Scenarios

python
from vmas import Scenario, Agent, World, Landmark

class MyScenario(Scenario):
    def make_world(self, batch_dim, device):
        world = World(batch_dim=batch_dim, device=device)
        world.add_agent(Agent(name="agent_0"))
        world.add_agent(Agent(name="agent_1"))
        world.add_landmark(Landmark(name="goal"))
        return world

    def reset_world(self, env, world):
        # Randomize positions
        for agent in world.agents:
            agent.set_pos(torch.rand(env.batch_dim, 2) * 2 - 1)

    def reward(self, agent, world):
        # Distance to goal
        goal = world.landmarks[0]
        return -torch.linalg.norm(agent.state.pos - goal.state.pos,
                                   dim=-1)

# Register and use
env = vmas.make_env(MyScenario(), num_envs=512)

Use Cases

  1. MARL research: Benchmark multi-agent algorithms
  2. Cooperative learning: Study emergent coordination
  3. Scalability testing: GPU-accelerated parallel training
  4. Custom scenarios: Design domain-specific multi-agent tasks
  5. Education: Teach multi-agent RL concepts
