Why is namespace verification important in Rails?

Rails applications often use different inheritance trees and helpers for different areas (e.g., Admin vs. Client), and applying patterns from one namespace to another often causes NoMethodErrors.

Is this skill specific to the Devise gem?

While it includes specialized patterns for Devise, the verification logic is generic and applies to any authentication, authorization, or custom helper pattern used in a Rails project.

What is an 'assumption bug' in Rails development?

An assumption bug occurs when an AI agent assumes a standard Rails helper exists, such as 'current_user', when the specific project actually uses a custom name like 'current_administrator'.

How does this skill improve code generation quality?

It mandates a search-first protocol using tools like 'rg' to find the ground truth in your specific codebase before writing any logic, ensuring generated code is compatible.

Productivity & Workflow

Verifies Ruby on Rails codebase patterns and naming conventions before code generation to prevent runtime errors and assumption-based bugs.

About

The Rails Context Verification skill implements a rigorous pre-implementation protocol for Claude Code, designed to eliminate 'assumption bugs' in Rails development. By forcing the agent to systematically verify authentication helpers, namespace conventions, controller inheritance, and route helpers using codebase searches (rg), it ensures that generated code aligns perfectly with the existing project structure. This is essential for enterprise-grade Rails applications where naming conventions often deviate from standard defaults across different namespaces like Admin, API, or Client.

Key Features

Pre-implementation validation of view helpers and model method signatures
Automatic discovery of Devise authentication scopes and helper methods
2 GitHub stars
Verification of instance variable availability within specific controller actions
Extraction of existing routing patterns to ensure correct URL helper usage
Systematic verification of namespace-specific patterns and inheritance

Use Cases

Onboarding Claude to legacy Rails projects with non-standard helper names
Developing features within multi-tenant systems where naming conventions change per namespace
Ensuring new admin dashboard views use the correct administrator authentication helpers
