Description

Motivation

Many docstrings in verl are missing, incomplete or in a messy format.

We might want to adopt a unified format (and complete them), better with automatic checking.

Plan

  • Choose a docstring standard (e.g., NumPy).
  • Unify the format.
  • Add automatic checking.
  • Complete all the docstrings.

Research direction
First, examine the existing docstring formats in the verl codebase to understand the current state. Then, research the NumPy docstring standard as a candidate for unified format. Look into automated tools such as pydocstyle or ruff for enforcement. The issue has no linked PRs and one comment; check that comment for any initial discussion or preferences. Plan to update files incrementally, starting with a few modules to establish a pattern.
