tidybot-sim-manager

tidybot-sim-manager is a skill for Claude Code, Codex from TidyBot-Services/Tidybot-Universe. It costs 66 tokens per session (954 once invoked), scanned A, original, Apache-2.0.

A guide for starting, stopping, restarting, and checking the health of a MuJoCo simulation and its agent server. MuJoCo is software that simulates how robots and other physical systems move.

In plain words
What is it for?
Use it when developing or testing robot skills, launching the simulation, running it without a graphical window, restarting failed services, or shutting them down.
Why use it?
It removes the need to remember the correct startup order, ports, processes, and readiness checks. This helps recover after crashes and avoid connecting to services that are not ready.

Written for no agent in particular: nothing here depends on one.

Not installable: its command points at a path on the author’s own machine, so it runs nowhere else. The line is /home/yifei/miniconda3/envs/tidybot-sim/bin/python.

Getting it into your agent

There is no command for this one: it runs only inside a plugin, and the catalogue could not identify which plugin ships it. The source is linked below.

Made for: Claude Code, Codex.

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

tidybot-sim-manager 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 11d 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.

Sim Manager

Environment

  • Conda env: /home/yifei/miniconda3/envs/tidybot-sim/bin/python
  • Sim dir: ~/tidybot_uni/sim
  • Agent server dir: ~/tidybot_uni/agent_server
  • DISPLAY: :1 (for GUI mode)

Ports

5556 Franka State ZMQ PUB
5557 Franka Stream ZMQ SUB

Starting

Order matters: sim server first, then agent server.

Step 1: Kill stale processes

fuser -k 5555/tcp 5556/tcp 5557/tcp 5570/tcp 5571/tcp 5580/tcp 8080/tcp 8081/tcp 50000/tcp 2>/dev/null
sleep 2

Step 2: Start sim server

cd ~/tidybot_uni/robocasa_sim && DISPLAY=:1 /home/yifei/miniconda3/envs/tidybot-sim/bin/python -u -m sim_server 2>&1
  • Use pty: true for unbuffered output
  • Use --no-gui for headless mode (no MuJoCo viewer)
  • Takes ~90 seconds to compile the kitchen scene — wait for [sim] Entering physics loop
  • Custom scene: --task BananaTestKitchen --layout 1 --style 1

Step 3: Start agent server

cd ~/tidybot_uni/agent_server && /home/yifei/miniconda3/envs/tidybot-sim/bin/python -u server.py --no-service-manager 2>&1
  • Wait for Uvicorn running on http://0.0.0.0:8080
  • Ignore mocap warnings (no mocap in sim)
  • Ignore arm monitor warnings (they settle after a few seconds)

Health Checks

curl localhost:8081/health    # Sim server
curl localhost:8080/health    # Agent server

Stopping

Kill both processes. Then clear ports to avoid conflicts on next start:

fuser -k 8080/tcp 8081/tcp 5555/tcp 5556/tcp 5557/tcp 5570/tcp 5571/tcp 5580/tcp 50000/tcp 2>/dev/null

Sim Reset API

  • POST localhost:8081/reset — soft reset (instant, restores initial state)
  • POST localhost:8081/reset/hard — hard reset (~2s, full scene reload)
  • Reset also happens automatically on lease release via the agent server

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.

tidybot-sim-manager is a skill published in the GitHub repository TidyBot-Services/Tidybot-Universe (56 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 66 tokens to every session and 954 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
