env-check Skill

This skill allows the agent to precisely identify the host environment to avoid cross-platform command errors.

🛠️ Usage

Use this skill before running any OS-specific terminal commands if the environment is unknown.

Detection Logic

1. Check OS: Use ADDITIONAL_METADATA (preferred) or run_command with $PSVersionTable (Windows) or uname -a (POSIX).
2. Check Shell: Identify if the terminal is PowerShell, cmd, bash, zsh, etc.
3. Check Tool Availability: Verify if specific binaries like rg, grep, jq, or git are available in the PATH.

💻 Platform-Specific Command Mapping

Task	Windows (PowerShell)	POSIX (Bash/Zsh)	Platform Tool (Best)
Search Text	Select-String -Pattern "query" -Path "file"	grep "query" "file"	grep_search
List Files	Get-ChildItem -Recurse	ls -R	list_dir
Read File	Get-Content "file"	cat "file"	view_file
JSON Parse	ConvertFrom-Json	jq	(N/A)

🛡️ Best Practices

• Priority: ALWAYS prefer platform-native tools (grep_search, list_dir, view_file) as they work consistently across all operating systems.
• Fallback: If a shell command is necessary, use a conditional block to provide both Windows and POSIX equivalents.
• Verification: Never assume a tool exists. Use Get-Command (Windows) or which (POSIX) to verify before execution.
