GitHub Copilot + LSP: Smarter Code Context and Better Token Efficiency

Sun, 09 Aug 2026 11:15:02 -0400

This guide walks through configuring Language Server Protocol (LSP) support for Go, Python, Ruby, TypeScript, and JavaScript in GitHub Copilot CLI. It also includes practices for keeping AI coding sessions efficient and token-conscious.

Part of a Series

This post is part of a broader series exploring how modern AI coding assistants understand and work with code.

The series starts with the foundations of how source code moves through the development toolchain—from ASTs and parsing to compilers and language servers (LSP)—and then builds on those concepts to explain how AI coding tools can use this information to navigate and reason about a codebase.

fast-deepseek: Building a Lightweight DeepSeek Client for Ruby

Wed, 26 Mar 2025 18:12:39 -0400

AI APIs have become remarkably easy to call.

The hard part isn’t sending an HTTP request. It’s deciding how much abstraction you actually need.

When I started experimenting with DeepSeek from Ruby, I didn’t want an AI framework, an agent abstraction, or a large dependency tree. I wanted this:

client = FastDeepseek::Client.new(
 api_key: ENV.fetch("DEEPSEEK_API_KEY")
)

response = client.chat(
 "Explain Ruby blocks in simple terms",
 model: "deepseek-chat"
)

That idea became fast-deepseek on RubyGems and fast-deepseek on GitHub — a lightweight Ruby client for the DeepSeek API.

Running DeepSeek-R1 Locally with Ollama

Mon, 10 Feb 2025 11:15:02 -0400

Introduction

DeepSeek-R1 is an advanced AI model that can be run locally for various natural language processing tasks. DeepSeek has suspended its usage top-up feature recently, and I had to find a way to use it locally in order to work on a side project. I have documented the steps, which resulted in this blog post.

In this post, we’ll walk through the process of setting up and running DeepSeek-R1 using Ollama, a tool designed for easily managing AI models locally. We will also test the setup using a curl command to verify its functionality.
