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
