Deleting 179 GitHub Repos with GitHub Copilot CLI in 15 Minutes

I reported a bug to GitHub. They fixed it in 2 days—then revamped their entire extension system. Here's what happened: While using GitHub Copilot CLI's extension system, I discovered a critical issue: creating a hook in an extension would override all global hooks. This broke my hook flows—the system I use to harden security across all my repositories. So I filed an issue. Within one week: • Root cause identified • Fix shipped to production • Complete extension system overhaul released The new capabilities are significant: → Custom slash commands now supported in the SDK → UI elicitation dialogs for structured user input → In-session management via /extensions command → Multi-language SDK support (Node.js, Python, Go, .NET) → Hot reload without full session restart This isn't just a bug fix. It's a signal. GitHub is treating Copilot CLI extensions as a first-class extensibility platform. For teams building internal tooling, security enforcement, or custom workflows—this changes the game. The speed of iteration here is remarkable. From power-user secret to documented, multi-language platform in 9 days. We're entering an era where developer feedback directly shapes the AI tools we use daily. If you're not experimenting with Copilot CLI extensions yet, now is the time. Full story in the video.

Why your "perfect" code is returning a 404 (and it’s not a typo). 🛑 I’ve been heads-down building SprintSync AI, an automated engine that translates raw Git Diffs into high-level sprint updates for teams. Yesterday, I hit a wall that every dev knows: the code is correct, the logic is sound, but the API says “I don’t exist.” I was trying to fetch code comparisons from private repos via the GitHub API. First, I hit ENOSPC because Next.js was generating more cache than my system could handle. Then, I hit the 404/403 loop. The Lesson: In the world of GitHub's new "Fine-grained" tokens, a 404 doesn't always mean "Not Found." Often, it's a security 404—GitHub is hiding the resource because it doesn't think you have the right to know it exists. How I solved it: Cleaned the pipes: Flushed the .next cache and pruned my Docker images to give the compiler room to breathe. Permission Pivot: Traded the finicky Fine-grained tokens for a Classic PAT with scoped repo access. The "Bearer" Fix: Ensured my headers were explicitly using the right authorization syntax. The Result: SprintSync AI is now pulling real-time, authenticated code changes into a clean AI-summarized dashboard. If you’re building with the GitHub API, don't let a 404 gaslight you. Check your token scopes first! #MicroSaaS #NextJS #GitHubAPI

GitHub engineering team tackled massive performance issues in the new React-based “Files changed” tab for huge pull requests, where things like 1GB JS heaps and laggy interactions were killing the vibe. By simplifying diff line components, ditching unnecessary DOM nodes and event handlers, adding virtualization for mega PRs, and optimizing state/rendering, they slashed memory by 50%, DOM nodes by 10-74%, and made interactions way snappier. https://lnkd.in/gC_Mweez

The Problem We've all been there: dozens of old repos from tutorials, abandoned side projects, and test experiments piling up. Cleaning them up one by one through the GitHub UI is painfully slow — especially when you need to delete 20+ at once. The Solution I got tired of the manual process, so I built GitHub Repo Bulk Deleter — a lightweight local web tool that lets you wipe out multiple repositories in seconds. How it works: Paste your GitHub token → your repos load automatically Search, filter by Public/Private, and tick the ones you want gone Confirm with a safety prompt → watch them delete in real time Key Features ✅ Auto-load: Fetches your entire repo list with one click — no URL copy-pasting ✅ Smart Select: Search, filter by visibility, or hit Select All ✅ Real-time Progress: Each deletion streams live via Server-Sent Events ✅ Safe by Design: Requires typing DELETE before anything is removed ✅ CLI Mode: Scriptable via file input or stdin for automation use cases Tech Stack Built with #NodeJS, #ExpressJS, and the #GitHubAPI — zero frontend frameworks, no build step required. Open Source The project is free, open-source, and ready for feedback! 👇 https://lnkd.in/gbX8MgNc #WebDev #SoftwareEngineering #OpenSource #CleanCode #Automation #GitHub #DeveloperTools #NodeJS

Paste any #GitHub #URL → get an interactive #architecture map of the entire codebase. No install. No account. No build step. It’s called #CodeFlow—and it’s literally a single HTML file. Open it, drop a repo link, and in seconds you get: → Interactive #dependencygraph → Blast #radiusanalysis for any file → Code #ownership from git history → Built-in security scanning → Pattern detection (factories, hooks, god objects, etc.) → Codebase health score (A–F) → Activity heatmap of commits → PR impact analysis 👉Everything runs locally in your browser. 👉Your code never leaves your machine. 👉Even private repos work—just add your GitHub token (stored in memory, cleared on close). 43 stars. One file. MIT licensed. Sometimes the simplest tools are the most dangerous.

Excited to share my latest project: Advanced GitHub Repo Manager! 💻 Ever found an amazing GitHub repository but lost track of it later? Or wanted a curated list of the best tools out there? I built this platform as a centralized catalog where developers can easily fetch, save, and share popular Git repositories for the whole community to discover and use! ✨ Key Features: 🔹 Live Fetching: Instantly preview GitHub repository metadata using the GitHub API. 🔹 Community Catalog: Search, filter (by language like Python, JS, TypeScript), and sort repositories saved by other users. 🔹 Personal Workspaces: Create an account to bookmark favorites and manage your own uploads. 🔹 Admin Dashboard: Full control over user roles, CSV imports/exports, and platform analytics. 🔹 UI/UX: Built-in Dark Mode 🌙 and responsive design! Building this was a great experience in API integration, database management, and creating a scalable architecture. Check out the video below for a quick walkthrough! 👇 Would love to hear your feedback in the comments. What is one GitHub repository you can't live without?

How GitHub Copilot Runs Safely in Docker Sandbox with MicroVMs Click here for source https://lnkd.in/get9BvdN Do you want to know more click here https://lnkd.in/exH3zxjM GitHub Copilot + MicroVMs via Docker Sandbox explained! In this video, I show how a local GitHub Copilot agent can run inside an isolated Docker Sandbox powered by MicroVMs for safer AI coding and agentic refactoring. You’ll learn how Docker Sandbox gives GitHub Copilot access to a private Docker daemon inside a MicroVM, so you can build images, modernizing legacy applications. I also cover how Docker Sandbox helps preserve the same workspace paths across the host and sandbox, why that matters for real projects, and how this setup can support GitHub Copilot CLI workflows with better isolation, security, and developer productivity. If you want to understand GitHub Copilot, MicroVMs, Docker Sandbox, secure AI coding agents, and agentic refactoring in a practical way, this video is for you.

Most developers are using GitHub Copilot wrong. It’s not about better prompts. It’s about better context. Copilot performs based on what you feed into it — not what you ask it. Here’s what actually makes a difference: • Instructions → enforce coding standards • Skills → inject domain knowledge • Agents → simulate specialized roles • MCP → connect external systems I applied this in my project by defining clear backend rules and structuring responses consistently across modules. Result: more predictable, cleaner, and reusable code. Prompt engineering gets attention. Context engineering gets results. #GitHubCopilot #AI #SoftwareEngineering #Java #FullStackDeveloper #ContextEngineering GitHub Microsoft
