Function unwrapAnnotationsLiteral

pkg/toolvalidation/readonlyhint.go:224–236

unwrapAnnotationsLiteral attempts to extract the *ast.CompositeLit for &mcp.ToolAnnotations{...} or mcp.ToolAnnotations{...} from an expression, resolving the MCP package's local alias per file.

(expr ast.Expr, aliases map[string]struct{})

// &mcp.ToolAnnotations{...} or mcp.ToolAnnotations{...} from an expression,
// resolving the MCP package's local alias per file.
func unwrapAnnotationsLiteral(expr ast.Expr, aliases map[string]struct{}) *ast.CompositeLit {
	if u, ok := expr.(*ast.UnaryExpr); ok && u.Op == token.AND {
		expr = u.X
	}
	cl, ok := expr.(*ast.CompositeLit)
	if !ok {
		return nil
	}
	if !isQualifiedType(cl.Type, aliases, "ToolAnnotations") {
		return nil
	}
	return cl
}

// extractToolName returns the literal value of the Name field of an mcp.Tool
// composite literal, or empty string if the value is not a basic string literal.
