Full skill instructions
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_Bridgemod enabled .NET 9 SDK(only needed to build the bridge mod)
