ShellCheck Configuration and Static Analysis

Comprehensive guidance for configuring and using ShellCheck to improve shell script quality, catch common pitfalls, and enforce best practices through static code analysis.

When to Use This Skill

Setting up linting for shell scripts in CI/CD pipelines
Analyzing existing shell scripts for issues
Understanding ShellCheck error codes and warnings
Configuring ShellCheck for specific project requirements
Integrating ShellCheck into development workflows
Suppressing false positives and configuring rule sets
Enforcing consistent code quality standards
Migrating scripts to meet quality gates

Detailed patterns and worked examples

Detailed pattern documentation lives in references/details.md. Read that file when the navigation tier above is insufficient.

Best Practices

Run ShellCheck in CI/CD - Catch issues before merging
Configure for your target shell - Don’t analyze bash as sh
Document exclusions - Explain why violations are suppressed
Address violations - Don’t just disable warnings
Enable strict mode - Use --enable=all with careful exclusions
Update regularly - Keep ShellCheck current for new checks
Use pre-commit hooks - Catch issues locally before pushing
Integrate with editors - Get real-time feedback during development

Issue colours

Resolved from a deterministic hash of the owner name. Two accent tones are generated per issue and each is proven against its own ground before it ships: a single accent that passes AA on both light and dark paper is arithmetically impossible.

Heading repairs

1 repair applied to this skill so the document has one h1 and no skipped levels:

Shifted “4 headings” from h1 to h2 so the skill title is the only h1.

Spec compliance

Every skill satisfies the Agent Skills specification’s frontmatter rules.

Images

Images inside a skill come from the upstream repository. Where the author gave no alternative text we mark the image decorative rather than inventing a description — a plausible caption we made up is worse than none for the reader who depends on it.

Marketplace

A plugin manifest is published at .claude-plugin/marketplace.json by Seth Hobson, declaring 94 plugins. It is read for editorial metadata only — never as the skill index, which is always the repository tree.

Signal

Install counts come from skills.sh. They measure downloads, not quality, and an unranked repository is not an unread one.

Agent surfaces

The whole issue is available as one markdown document at /wshobson/agents.md, and each skill at its own .md URL.

Publication

Set by Skills Docs from the source repository. Body text is Literata at the reader’s chosen size and measure; code is Geist Mono. Nothing on this page was written by us except this paragraph.
