cli-anything-slay-the-spire-ii

A stateful command-line interface for controlling the real Slay the Spire 2 game through the local STS2_Bridge mod. The CLI reads normalized game state and sends action commands via a local HTTP API at localhost:15526.

Installation

This CLI requires a bridge mod that runs inside the game process. Both the CLI and the bridge are distributed from the same repository:

https://github.com/HKUDS/CLI-Anything

1. Install the CLI

git clone https://github.com/HKUDS/CLI-Anything.git
cd CLI-Anything/slay_the_spire_ii/agent-harness
pip install -e .

2. Build and install the bridge mod

The bridge mod is a .NET 9 plugin that must be compiled and installed into the game directory. Full instructions are in the repository README, but the short version is:

cd CLI-Anything/slay_the_spire_ii/agent-harness/bridge/plugin
./build.sh
cd ../install
./install_bridge.sh

If the build script cannot auto-detect the game data directory, set STS2_GAME_DATA_DIR explicitly:

STS2_GAME_DATA_DIR="/path/to/data_sts2" ./build.sh

3. Enable the mod and verify

Launch Slay the Spire 2 via Steam, enable the STS2_Bridge mod in the mod manager, then verify the connection:

cli-anything-sts2 state

If this returns JSON, the CLI and bridge are connected.

Prerequisites:

Python 3.10+
Slay the Spire 2 (Steam) with STS2_Bridge mod enabled
.NET 9 SDK (only needed to build the bridge mod)

For AI Agents

Always read state first to get the decision field
Re-read state after each action - indices and energy change during combat
Check return codes - 0 for success, non-zero for errors
Parse stdout for JSON output
