Are there any useful LLM assistants (cursor/copilot/others) for fp-ts?

[tonisives]

For normal Typescript code, especially React, Cursor is very useful. It generates components as I write them, and I can save a ton of time. I use Cursor with claude-3-5-sonnet.

However, with fp-ts, I find that Cursor doesn't understand the context of fp-ts at all. It suggest wrong/irrelevant code most of the time. I actually find it detrimental to my coding speed, and turn Cursor off when writing fp-ts pipe functions.

Granted, I use custom imports, like R instead of RTE.

export let rollAfterCheckpoint =
  (token: string, cpType: CpType) =>
  (checkpoint: Event | null, offset = 0): ReaderTE<Deps, AnyError, void> =>
    pipe(
      getPage(checkpoint),
      R.map(debugLog),
      R.chain(rollPage(cpType)),
      R.chain(getNextPage(offset, cpType)),
      R.local((deps) => ({ ...deps, token })),
    )

I think the LLM doesn't understand the concept of function pointers especially, as it tries to force the code into the pipe inline, and not create new functions. This is just one observation. It also doesn't seem to grasp the difference between TE.tryCatch and try {} catch {}, and so on.

Does anyone find any LLM assistants useful? What kind of flow to use to make them give useful/relevant suggestions?
