lint

Run linting tools and fix issues before pushing code.

Workflow

1. Check What Changed

git diff --name-only HEAD~1
# or for unstaged changes
git diff --name-only

2. Run Linters

Ruby files:

# Check only
bundle exec rubocop

# Auto-fix
bundle exec rubocop -A

ERB templates:

# Check only
bundle exec erblint --lint-all

# Auto-fix
bundle exec erblint --lint-all --autocorrect

Security scan:

bin/brakeman --no-pager

3. Handle Results

If auto-fix worked:

git add -A && git commit -m "style: linting"

If manual fixes needed:

• Report specific issues with file:line references
• Suggest fixes for common patterns

4. Common Issues

Issue	Fix
Line too long	Break into multiple lines
Missing frozen_string_literal	Add # frozen_string_literal: true at top
Trailing whitespace	Remove trailing spaces
Missing newline at EOF	Add blank line at end
