SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill detects your active shell and automatically applies the correct quoting and escaping rules for Bash, Zsh, Fish, PowerShell, and CMD, reducing quoting errors and debugging time.

Core Features & Use Cases

  • Shell Detection: Automatically identifies Bash, Zsh, Fish, PowerShell, CMD, and other common shells.
  • Quoting Rules: Applies the appropriate quoting and escaping strategy for each shell to prevent word splitting and globbing.
  • Nested Command Handling: Manages complex, multi-level command nesting across shells (e.g., Bash -> PowerShell, CMD -> Bash) with minimal manual tweaking.
  • Use Case: A developer needs to run a command across two shells in a CI script; Quotefix ensures correct quoting, avoiding errors and saving time.

Quick Start

Try a simple cross-shell command: ask Claude to run a PowerShell snippet from Bash; Quotefix will automatically apply the correct quoting and escaping.

FAQPage Schema
How do I fix quoting errors when running commands across different shells?

Quotefix automatically detects your active shell—Bash, Zsh, PowerShell, CMD, or Fish—and applies the correct quoting and escaping rules. This prevents word splitting, globbing errors, and nested command failures across shell boundaries without manual adjustment.

Can I run PowerShell commands from Bash without manually fixing escaping?

Yes. Quotefix handles cross-shell nesting by detecting both the parent shell and target shell, then applying appropriate quoting strategies—single quotes, double quotes, backticks, here-strings, or stop-parsing tokens—so nested commands execute correctly.

What's the best way to handle file paths with spaces in shell scripts?

Quotefix applies shell-specific quoting rules that prevent spaces from splitting file paths into multiple arguments. It ensures UTF-8 filenames are quoted correctly for your active shell, whether Bash, PowerShell, or CMD.

Does this work for CI scripts that run across multiple shells?

Yes. Quotefix detects the shell environment at runtime and applies the correct escaping for each step, making it ideal for CI pipelines that invoke commands in different shells sequentially or in parallel.

Why do my nested commands fail when switching between shells?

Different shells interpret quoting, escaping, and special characters differently. Quotefix identifies your shell type from environment variables or process checks and applies shell-specific rules, so multi-level nesting (Bash → PowerShell → CMD) works reliably.

How does shell detection work in Claude Code environments?

Quotefix checks environment variables and processes to identify the active shell, then exposes machine-readable metadata frontmatter so you can inspect which quoting strategy was applied and debug escaping issues.
