How does Guardrail Builder improve my AI coding workflow?

It captures the 'lessons learned' during your coding sessions and saves them as Markdown files. Claude Code then automatically references these files, ensuring it doesn't make the same mistake twice.

Do I need to manually import these rules into my configuration?

No, files placed in the .claude/rules/ directory are automatically loaded by Claude Code as project memory, so no manual @ imports are necessary.

Can I target rules to specific folders?

Yes, Guardrail Builder supports 'paths' in the file frontmatter, allowing you to restrict a rule to specific file types or directories like src/api/**/* or **/*.test.ts.

How does it handle duplicate information?

The skill performs a semantic check against existing files in your rules directory. If a new insight is already covered by an existing rule, it will skip it or update the existing file if there is new information.
