What it does
Openenv Agentic Rl is an agent skill from burtenshaw/training-agents. Use when designing, reviewing, or implementing OpenEnv-style environment interfaces for agentic RL with TRL, including reset/step/state contracts, tasksets, Docker or HTTP/WebSocket serving, MCP compatibility, reward separation, and GRPO environment rollouts.
Its SKILL.md is about 380 tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including reference files (for example `agents/openai.yaml`, `references/environment-contract.md` and `references/trl-rollouts.md`).
It sits in Backend & APIs, covering Realtime and WebSockets, Fine-tuning and Containers. It works with Model Context Protocol and Docker. The repository describes itself as: A repo on resources for training agents. The licence is Apache-2.0.
When your agent uses it
- Implementing OpenEnv-style environment interfaces for agentic RL with TRL
- Including reset/step/state contracts
- HTTP/WebSocket serving
- MCP compatibility
Example prompts
- “/openenv-agentic-rl”
Requirements
- Docker
Workflow steps
6 steps, taken from the first numbered list in SKILL.md.
- Define the task and whether stateful interaction is actually needed.
- Specify reset, step, state, terminal state, action schema, and
- Keep reward logic in the trainer/eval layer or a clearly versioned scorer.
- Add a small taskset with train/eval separation.
- Connect rollouts to TRL GRPO or a similar online RL method.
- Record traces for later self-distillation.
What it can do on your machine
Read from SKILL.md and the folder at commit ec7cc54. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Openenv Agentic Rl loads about 381 tokens when it runs, and up to ~665 if it reads all its reference files. Until then it costs about 70 tokens; SKILL.md has 164 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- description
- Use when designing, reviewing, or implementing OpenEnv-style environment interfaces for agentic RL with TRL, including reset/step/state contracts, tasksets, Docker or HTTP/WebSocket serving, MCP compatibility, reward separation, and GRPO environment rollouts.
OpenEnv Agentic RL
Use this skill when an agent training task needs an interactive environment rather than a static prompt.
OpenEnv should be treated as an interoperability layer between harness, environment, and trainer. It should not own the reward definition or training algorithm.
Workflow
- Define the task and whether stateful interaction is actually needed.
- Specify
reset,step,state, terminal state, action schema, and observation schema. - Keep reward logic in the trainer/eval layer or a clearly versioned scorer.
- Add a small taskset with train/eval separation.
- Connect rollouts to TRL GRPO or a similar online RL method.
- Record traces for later self-distillation.
Checks
- Observations must not leak labels or future state.
- Train and eval tasks should be separated.
- The local smoke environment should run without cloud infrastructure.
- Environment transport should match deployment needs: local process, Docker, HTTP, WebSocket, or MCP.
- The same interface should support both training and evaluation.
