Can this skill help with script path detection?

Yes, it provides a reliable template that uses BASH_SOURCE for Bash and specialized expansion flags for Zsh to find the script's directory accurately in both shells.

How does this skill handle array indexing differences?

It suggests shell-neutral workarounds such as enabling KSH_ARRAYS in Zsh or using universal traversal methods to bridge the gap between 0-based and 1-based indexing.

Why does the skill advise against 'over checking' files?

If a file is already tracked by Git or an environment variable is guaranteed by a setup script, redundant existence checks clutter the code and add unnecessary complexity.

What is shell-neutral behavior?

Shell-neutral behavior refers to writing scripts using syntax and logic that functions identically in both Bash and Zsh, preventing errors caused by shell-specific defaults.

開発者ツール

Reviews shell scripts to ensure cross-shell compatibility and reliability between Bash and Zsh environments.

概要

The Shell Script Reviewer skill provides specialized logic to identify and fix compatibility issues in shell scripts, focusing primarily on the discrepancies between Bash and Zsh. It enforces shell-neutral implementation patterns for array indexing, script path detection, and variable expansion while discouraging redundant existence checks for Git-tracked files. This skill is essential for developers creating portable automation tools, CI/CD pipelines, and developer environments that must function predictably across different default shells.

主な機能

Identifies and resolves array indexing differences between Bash (0-based) and Zsh (1-based).
Standardizes variable expansion and word-splitting behaviors across shells.
Provides shell-neutral templates for reliable script path and directory detection.
Audits globbing patterns and associative array syntax for maximum portability.
37 GitHub stars
Enforces best practices like avoiding the reserved $path variable in Zsh.

ユースケース

Refactoring Bash-specific deployment scripts to support Zsh users.
Optimizing script performance by removing redundant file and environment variable checks.
Auditing repository automation tools for cross-platform reliability.
