Loom
Loom is a service that allows you to record video of your screen conveniently and effortlessly. This way, you can improve the quality of comments perception by the development team and all stakeholders. Do not forget that the perception of information is a very important aspect, and by using video recordings, you can save both your efforts in the future and the understanding of a specific task by the development team.
Figma/sketch/wireframe
Now we are talking about services that can help visualize your ideas. In the classical format of working on a project and tasks, for example, Figma is used as a tool for creating a website design by the designer, while the customer/stakeholders for the project only communicate with each other through comments. In such a format, it is very easy to get caught in the "array of comments", which leads to a misunderstanding of the changes that need to be made.
To avoid this or to set the task in the right direction, I would recommend mastering these services at least at the "beginner" level. This will allow you to visually express your wishes, and even create simple prototypes, which will help the task to be more understandable and easier to implement.
P.S. Such sketches are useful both at the stage of creating a design and preparing a task scoping for the development team.
Diagrams.net, Google Drawings, Figma Jam
These services can be useful for creating architectural solutions and building the logic of interaction between functions on a website. For example, Diagrams.net has a large pool of tools that almost automate the work with diagrams. You can easily build hierarchies and specify flow endpoints.
