Custom Chat participants (formerly agents) such as @workspace

[DRKolev-code]

Are there plans to let us create custom Chat Participants (plugins) in the same vein as @buffer and @buffers? If so would it be feasible to enable them, via a similar mechanism as cmp, as a list of repositories?

I think in this plugin scope it would be custom conext function I think? Even though custom selector also already can be used for same thing. I personally think the nvim-cmp "extension" system is terrible so I would def not want to go that route. For custom selector you can pass custom selection already as function, and I think for context we could do the same.

I think so too. Being able to specify custom contexts would fit. Something like:

contexts = {
  new_context = {
    -- Maybe it can receive the selection and if there is a parameter in the prompts section, for each prompt, to specify the context for that prompt, it could auto pass the selection the the context's callback function.
    callback =  function(selection) {...},
    -- If the code is online
    url = "",
    description = "",
  }
}

Would a rename to participants be a good idea?
Maybe the prompts should have a context/participant field to indicate which to use.

Well that was pretty easy to implement for me, but I am still dubious about why this wasn't taken in consideration given the ease of implementation; wondering if there's any gotchas
