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.

生産性とワークフロー

Automatically captures and organizes project insights and coding standards into persistent Markdown rules for Claude Code.

概要

Guardrail Builder streamlines the creation of project-specific guidelines by analyzing your conversation history to extract lessons learned, architecture patterns, and error fixes. It follows a modular '1-rule-1-Markdown' approach, saving insights into categorized directories within .claude/rules/ for automatic loading by Claude Code. This ensures your AI agent maintains a consistent project memory, preventing the repetition of past mistakes and adhering strictly to your unique codebase requirements without manual documentation overhead.
