Module: RailsAiContext::Confidence

Defined in:
lib/rails_ai_context/confidence.rb

Overview

Confidence tags for AST introspection results. Shared across tools and introspectors without creating cross-layer dependencies.

VERIFIED: value extracted from a static, deterministic AST node

(symbol literals, string literals, integers, booleans).

INFERRED: value involves dynamic expressions, metaprogramming,

or runtime-only constructs that AST cannot fully resolve.

Class Method Details

.for_node(node) ⇒ Object

Determine confidence level for a Prism call node’s arguments. Returns VERIFIED if all arguments are static literals, INFERRED if any argument is a dynamic expression.

def self.for_node(node)
  args = node.arguments&.arguments
  return VERIFIED unless args

  static = args.all? { |a| static_node?(a) }
  static ? VERIFIED : INFERRED
end

.static_node?(node) ⇒ Boolean

Recursively check if a node is a static literal.

Returns:

  • (Boolean)
