What it does

Add Workflow is an agent skill from areal-project/AReaL. Guide for adding a new RolloutWorkflow to AReaL. Use when user wants to create a new workflow.

Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: The RL Bridge for LLM-based Agent Applications. Made Simple & Flexible. The licence is Apache-2.0.

When your agent uses it

User wants to create a new workflow

Example prompts

“/add-workflow”

Requirements

Python 3

Workflow steps

4 steps, taken from the step headings in SKILL.md.

Create Workflow File
Register in init.py
Update Entry Script
Add Tests

What it can do on your machine

Read from SKILL.md and the folder at commit a642540. 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 (its code samples are python).
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

Add Workflow loads about 1.1k tokens when it runs. Until then it costs about 27 tokens; SKILL.md has 178 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~27
When it runs · the whole SKILL.md, loaded when a task matches: ~1.1k

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.

name: add-workflow
description: Guide for adding a new RolloutWorkflow to AReaL. Use when user wants to create a new workflow.

Add Workflow

Add a new RolloutWorkflow implementation to AReaL.

When to Use

This skill is triggered when:

User asks "how do I add a workflow?"
User wants to create a new RolloutWorkflow
User mentions implementing a custom rollout

Prerequisites

Before starting, ensure you understand:

The workflow's purpose and requirements
Input/output data format
Reward function to use

Step-by-Step Guide

Step 1: Create Workflow File

Create areal/workflow/<name>.py:

python

import uuid
from typing import Any, Callable

import torch

from areal.api.cli_args import GenerationHyperparameters
from areal.api.engine_api import InferenceEngine
from areal.api.io_struct import ModelRequest, ModelResponse
from areal.api.reward_api import AsyncRewardWrapper
from areal.api.workflow_api import RolloutWorkflow
from areal.utils import logging

logger = logging.getLogger("MyWorkflow")


class MyWorkflow(RolloutWorkflow):
    """Description of your workflow."""

    def __init__(
        self,
        gconfig: GenerationHyperparameters,
        tokenizer,
        reward_fn: Callable,
    ):
        self.gconfig = gconfig.new_with_stop_and_pad_token_ids(tokenizer)
        self.tokenizer = tokenizer
        self.async_reward_fn = AsyncRewardWrapper(reward_fn)

    async def arun_episode(
        self,
        engine: InferenceEngine,
        data: dict[str, Any],
    ) -> dict[str, Any] | None | dict[str, InteractionWithTokenLogpReward]:
        """Run a single episode. MUST be async and non-blocking."""

        # 1. Prepare input_ids from data
        input_ids = self.tokenizer.apply_chat_template(
            data["messages"],
            tokenize=True,
            add_generation_prompt=True,
        )

        # 2. Build ModelRequest
        req = ModelRequest(
            rid=uuid.uuid4().hex,
            input_ids=list(input_ids),
            gconfig=self.gconfig.new(n_samples=1),
            tokenizer=self.tokenizer,
        )

        # 3. Generate completion (async)
        resp: ModelResponse = await engine.agenerate(req)

        # 4. Compute reward (async)
        prompt_str = self.tokenizer.decode(input_ids)
        completion_str = self.tokenizer.decode(resp.output_tokens)
        reward = await self.async_reward_fn(
            prompt_str,
            completion_str,
            resp.input_tokens,
            resp.output_tokens,
            **data,
        )

        # 5. Return results in expected format
        return {
            "input_ids": torch.tensor(resp.input_tokens),
            "output_ids": torch.tensor(resp.output_tokens),
            "reward": torch.tensor(reward),
        }

Step 2: Register in init.py

Add to areal/workflow/__init__.py:

python

from areal.workflow.<name> import MyWorkflow

__all__ = [
    # ... existing exports
    "MyWorkflow",
]

Step 3: Update Entry Script

Update your training script to use the new workflow:

python

trainer.train(
    workflow="areal.workflow.<name>.MyWorkflow",
    # ... other args
)

Step 4: Add Tests

Create tests/test_<name>_workflow.py:

python

import pytest
from areal.workflow.<name> import MyWorkflow

@pytest.mark.asyncio
async def test_workflow_basic():
    # Test basic functionality
    pass

Reference Implementations

Workflow	File	Description
MultiTurnWorkflow	`areal/workflow/multi_turn.py`	Multi-turn conversation
RLVRWorkflow	`areal/workflow/rlvr.py`	RL with verifiable rewards
VisionRLVRWorkflow	`areal/workflow/vision_rlvr.py`	Vision + RLVR

Key Requirements

Async: arun_episode must be async def and non-blocking
No sync I/O: Use aiofiles for file operations
Wrap rewards: Use AsyncRewardWrapper for reward functions
Tensor format: Output tensors should be [batch, seq_len, ...]
Use helpers: concat_padded_tensors for combining outputs

Common Mistakes

Using open() instead of aiofiles.open()
Forgetting to await async calls
Not wrapping reward function with AsyncRewardWrapper
Wrong tensor shape conventions
