cpp-reinforcement-learning SKILL.md skillA
cpp-reinforcement-learning from aznatkoiny/zai-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add aznatkoiny/zai-skills/cpp-reinforcement-learning@git:20261010.5b03da5Pins git:20261010.5b03da5 in mdr.lock. Pin the fingerprint instead.

Reinforcement learning in C++ with LibTorch (the PyTorch C++ frontend) and C++20. Use when the user is implementing DQN, PPO or SAC in C++, building a replay buffer or rollout buffer in C++, fixing libtorch memory growth or GPU issues in a C++ agent, running environments in parallel threads, or loading a policy trained in Python into a C++ program (games, robotics, simulators). Not for Python RL with Gymnasium or Stable-Baselines3, including exporting a Python policy to ONNX…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# C++ reinforcement learning
Help the user build RL in C++ that is correct first and fast second. The C++ frontend mirrors PyTorch's Python API closely, so a good approach is often to get the algorithm right against a Python reference (Stable-Baselines3 or CleanRL) and then translate it, checking the outputs match.
LibTorch changes between releases, and current versions require C++20. Check the version the user builds against (it's in `<libtorch>/build-version`) before relying on an API, and if a docs or web tool is available, look up anything you're unsure of.
## Core Libraries
### Primary: LibTorch (PyTorch C++ Frontend)
LibTorch provides the same tensor operations and autograd capabilities as PyTorch in C++.
**Installation**: Download from https://pytorch.org/get-started/locally (select C++/LibTorch)
**CMake Integration**:
```cmake
cmake_minimum_required(VERSION 3.18)
project(rl_project)
set(CMAKE_CXX_STANDARD 20) # current libtorch requires C++20
find_package(Torch REQUIRED)
add_executable(train_agent src/main.cpp)
target_link_libraries(train_agent "${TORCH_LIBRARIES}")
```

How to install
mdr add aznatkoiny/zai-skills/cpp-reinforcement-learning@sha256:0eea3a9fdbbd5ef2The line at the top of this page pins the label git:20261010.5b03da5, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
