Create distinctive, production-grade frontend interfaces with high design quality. Use when building web components, pages, or applications. Includes framework-specific guidance for Tailwind, React, Vue, and Rails/Hotwire ecosystems.
Skill file structure, naming conventions, directory layout, frontmatter requirements, and invocation control. Use when creating skill files or slash commands to ensure correct format and validation.
Forces adversarial reasoning before committing to decisions. Triggers on architectural choices, approach selection, and planning phases to prevent premature commitment bias.

Review database constraints, foreign keys, and data integrity rules.
# PROBLEM: Model-only validation (race condition vulnerable)
validates :email, uniqueness: true
# SOLUTION: Database constraint + model validation
add_index :users, :email, unique: true
validates :email, uniqueness: true
# PROBLEM: Check-then-insert race condition
def claim_slot
return false if Slot.where(user_id: user.id).exists?
Slot.create!(user_id: user.id)
end
# SOLUTION: Database constraint with rescue
.create!( user.id)
| Validation | Required DB Constraint |
|---|---|
presence: true | NOT NULL |
uniqueness: true | Unique index |
belongs_to | Foreign key |
enum | Check constraint |
numericality: { in: } | Check constraint |
# PROBLEM: Orphaned records on deletion
has_many :comments
# SOLUTION: Dependent handling
has_many :comments, dependent: :destroy # For callbacks
# OR database-level:
add_foreign_key :comments, :posts, on_delete: :cascade
# PROBLEM: No referential integrity for polymorphics
belongs_to :commentable, polymorphic: true
# SOLUTION: Validate type + consider alternatives
ALLOWED_TYPES = %w[Post Article].freeze
validates :commentable_type, inclusion: { in: ALLOWED_TYPES }
# Better: separate tables instead of polymorphic
belongs_to :post, optional: true
belongs_to :article, optional: true
validates :post_id, presence: true, unless: :article_id?
# Find orphaned comments (missing parent)
Comment.left_joins(:post).where(posts: { id: nil })
# Find missing foreign keys
ActiveRecord::Base.connection.tables.each do |table|
columns = ActiveRecord::Base.connection.columns(table)
columns.select { |c| c.name.end_with?('_id') }.each do |col|
# Check if FK exists
end
end
uniqueness validations have unique indexes?presence validations have NOT NULL constraints?_id columns have foreign keys?## Constraints Review: [PASS/WARN/FAIL]
### Missing Database Constraints
- [model]: [validation without DB enforcement]
### Foreign Key Issues
- [table]: [missing FK on _id column]
### Race Condition Risks
- [code location]: [check-then-insert pattern]
### Orphan Risks
- [association]: [could create orphans]
### Recommendations
