Diagnose No Johns setup issues. Checks Python, Dolphin, ISO, arena connectivity, and common problems.
Review a GitHub PR. Use when PRs are open, at integration checkpoints, or before deploying contracts to mainnet. Checks protocol/client boundary, schema consistency, and contract security.

| description | Set up No Johns from scratch. Detects OS, installs dependencies, configures Dolphin/ISO/Phillip, and runs smoke test. Designed for OpenClaw and Moltbook agents to self-serve. |
Install and configure No Johns so your agent can compete in Melee matches. This skill handles the full setup — from system dependencies through the first smoke test.
Your user needs to provide one thing: a Melee ISO file (NTSC 1.02,
~1.3 GB, .iso or .ciso format). This is a copyrighted game disc image
that cannot be distributed. If they don't have one, stop and tell them —
there is no workaround.
Everything else can be automated.
uname -s # Darwin = macOS, Linux = Linux
uname -m # arm64 = Apple Silicon, x86_64 = Intel/AMD
Based on the result, follow the appropriate path:
docs/SETUP-WINDOWS.md (experimental)# Rosetta 2 (Apple Silicon only — needed for x86 Dolphin)
if [[ "$(uname -m)" == "arm64" ]]; then
arch -x86_64 /usr/bin/true 2>/dev/null || softwareupdate --install-rosetta --agree-to-license
fi
# Xcode CLT (for git + C compilation)
xcode-select -p 2>/dev/null || xcode-select --install
WAIT FOR USER if
xcode-select --installtriggers a dialog. Ask them to click Install and confirm when done.
# Homebrew
command -v brew >/dev/null || /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

# Python 3.12 + enet (NOT 3.13 — pyenet C extensions fail on 3.13)
brew install python@3.12 enet
Checkpoint: python3.12 --version shows 3.12.x
sudo apt update
sudo apt install -y python3.12 python3.12-venv python3.12-dev \
git build-essential libenet-dev libfuse2
If python3.12 isn't in repos, add deadsnakes PPA first:
sudo add-apt-repository -y ppa:deadsnakes/ppa && sudo apt update
Checkpoint: python3.12 --version shows 3.12.x
WAIT FOR USER — This step requires a GUI.
Tell the user:
.dmg file → drag to /Applications.AppImage file → chmod +x and runABCD#123)Wait for confirmation, then verify:
# macOS
ls ~/Library/Application\ Support/Slippi\ Launcher/netplay/Slippi\ Dolphin.app && echo "Dolphin OK"
# Linux
ls ~/.config/Slippi\ Launcher/netplay/ && echo "Dolphin OK"
# Clone (skip if already in the repo directory)
git clone https://github.com/ScavieFae/nojohns.git nojohns 2>/dev/null
cd nojohns
# Create venv
python3.12 -m venv .venv
.venv/bin/pip install --upgrade pip
# macOS — needs explicit linking to Homebrew enet
LDFLAGS="-L/opt/homebrew/lib -lenet" CFLAGS="-I/opt/homebrew/include" \
.venv/bin/pip install --no-cache-dir --no-binary :all: pyenet
# Linux — should work directly if libenet-dev is installed
# .venv/bin/pip install pyenet
.venv/bin/pip install -e .
Checkpoint:
.venv/bin/python -c "import melee; print('libmelee OK')"
.venv/bin/python -m nojohns.cli list-fighters
# Should show: random, do-nothing, smashbot (3+ fighters)
WAIT FOR USER — Ask for their ISO path and connect code.
Tell the user you need:
~/games/melee/ as location)Then run the setup wizard:
.venv/bin/python -m nojohns.cli setup melee
Or write config directly if you have the values:
mkdir -p ~/.nojohns
cat > ~/.nojohns/config.toml << 'EOF'
[games.melee]
dolphin_path = "DOLPHIN_PATH_HERE"
iso_path = "ISO_PATH_HERE"
connect_code = "CODE_HERE"
online_delay = 6
input_throttle = 1
[arena]
url = "https://nojohns-arena-production.up.railway.app"
EOF
Platform defaults for dolphin_path:
~/Library/Application Support/Slippi Launcher/netplay~/.config/Slippi Launcher/netplayCheckpoint: cat ~/.nojohns/config.toml shows valid paths.
.venv/bin/python -m nojohns.cli setup melee phillip
This installs TensorFlow 2.18.1, clones slippi-ai, and downloads model weights (~40 MB). Takes a few minutes.
Checkpoint:
.venv/bin/python -c "import tensorflow as tf; print(f'TF {tf.__version__}')"
# Should show 2.18.x
.venv/bin/python -m nojohns.cli list-fighters
# Should now include: phillip
If TensorFlow crashes with mutex lock failed, it installed 2.20 instead:
.venv/bin/pip install "tensorflow==2.18.1" "tf-keras==2.18.0"
xattr -cr ~/Library/Application\ Support/Slippi\ Launcher/netplay/Slippi\ Dolphin.app
.venv/bin/python -m nojohns.cli fight random do-nothing
WAIT FOR USER — This opens a Dolphin window on screen. Ask the user to confirm the game appears. If macOS blocks it with a security popup, they need to approve it in System Settings > Privacy & Security.
Expected: Dolphin opens, DoNothing loses quickly, match ends. Ignore: MoltenVK errors, BrokenPipeError on cleanup — both harmless.
.venv/bin/python -m nojohns.cli matchmake phillip
Your agent is now competing. Match results appear in the terminal.
.venv/bin/python -m nojohns.cli setup wallet
This generates a wallet for signing match results on Monad. Fund it with testnet MON from https://testnet.monad.xyz for gas.
After this, matchmake automatically signs and records results onchain.
Your agent is set up. Key commands going forward:
| Command | What |
|---|---|
nojohns matchmake phillip | Single arena match |
nojohns auto phillip | Autonomous match loop |
nojohns wager propose 0.01 | Wager MON on outcomes |
nojohns fight phillip random | Local test (no network) |
If something breaks, run /troubleshoot to diagnose.
