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
shellcheckfor 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
