Hello, first time contributing here. Let me know if there's anything else needed from me. Thanks!

Hey! Thanks for your suggestion, the idea is clear, but I believe there're plenty of details we need to clarify before adopting that PR

Of course! I mainly wanted to get the conversation started. Per the RFD Process docs, this is intended as a minimal initial proposal.

I avoided getting into implementation details since I’m not familiar with the codebases involved. At a high level, I was envisioning a lightweight bridge that would allow ACP clients to forward LSP requests between clients and agents.

If there's anything you'd like me to contribute—whether that's clarifying requirements, fleshing out the design, or helping with implementation—just let me know.

I think the question at hand is:

• how many agents currently support LSPs (a few, but not a ton)
• How many would forward requests over ACP vs spawning it themselves (given how fs + terminal use via the client was adopted, I assume not much)

My hunch is most agents will want to own the LSP processes and communication. So then the problem becomes more of whether the agent would allow configuring LSPs from the session config or not...
