name: language-shell description: Shell scripting standards and safety practices. Use when language shell guidance is required or when selecting Shell as a thin wrapper or OS-near glue layer. allowed-tools:

• Bash(shellcheck)

Key Execution Capabilities

Script Validation

• Run syntax checking: bash -n, sh -n, zsh -n
• Execute static analysis with shellcheck
• Validate shebang lines and strict mode compliance
• Check for security vulnerabilities and coding violations

Tool Integration

• Use shellcheck for comprehensive linting
• Leverage shell-specific parameter expansion features
• Apply POSIX vs bash vs zsh feature detection
• Implement platform-specific compatibility checks

Execution Context

• Process script files from filesystem layer
• Generate structured reports with line-by-line findings
• Create minimal, rule-compliant patches for violations
• Maintain separation between governance rules and execution tools

Error Handling

This skill provides execution-layer error handling for shell script analysis:

• Invalid file formats or permissions
• Tool availability issues (missing shellcheck, etc.)
• Platform-specific limitations
• Syntax validation failures

Usage Notes

• Always delegate to governance rules for policy decisions
• Focus on concrete tool execution and result processing
• Provide deterministic, tool-first analysis results
• Maintain separation between rule definition and rule application
