Welcome to the forum!
If you are not using a tool such as Codex that supports skills and slash commands, it may be worth considering.
I know Codex is often thought of as a source-code development tool, but OpenAI’s own materials show it being used for more than writing code. The OpenAI Academy describes Codex as a way to write code, run tasks, and build automated workflows. That broader framing is important because many repeatable workflows are not strictly “programming” tasks.
The main value, at least for how I use these tools, is not just that Codex can edit files. It is that skills and slash commands let you make recurring work more repeatable.
A skill can act like a reusable playbook: it can capture instructions, conventions, examples, and workflow steps that you do not want to explain from scratch every time. This is useful when the same kind of task comes up repeatedly, especially when consistency matters.
Slash commands are useful for a related reason. They provide a quick way to trigger common actions or reusable prompt workflows without retyping the same instructions each time.
I have not tested the desktop apps or other interfaces enough to comment on them in detail, although some of them may support similar workflows. For my use case, the important capabilities are skills and slash commands.
