When building portable Agent Plugins with local MCP servers, you can't rely on hardcoded file paths. How should you set those paths in mcp_config.json? The three choices at a high-level: 📁 Expansion in cwd sets the server's working directory to the plugin root and keeps script paths short and readable. ⚙️ Expansion in args leaves the user's workspace as the working directory and passes full paths as command-line arguments. 🌐 Expansion in env injects paths into environment variables so tools can read them directly without CLI flag parsing, at the cost of extra config and required fallbacks for local testing. Read the article for my recommendations, trade-offs and how to pick the right setup for your server. How are you configuring paths in your Agent Plugins? Tell me in the comments! 👇 #CodingAgents #AgentPlugins #SoftwareEngineering #GenerativeAI linkedin.com/pulse/agent-plu…

I've said a lot recently that the industry feels "frothy" right now. Lots of change. New models. New standards. New audiences. New ways of working. I found this quote that really resonates. "Times and conditions change so rapidly that we must keep our aim constantly focused on the future." - Walt Disney When we're focused on this week's standard, next month's model, etc it can be hard to see the bigger picture. If you look ahead into the future, what are you excited about? For me, it is a reality where people can create software that meets their unique needs.

Should you still use /plan mode in AI coding agents? The two big complaints: 1. Context bloat from extended thinking tokens 2. Waterfall execution that breaks on real code surprises Two quick fixes: • Fresh sessions: take the plan into a clean session to avoid context pollution • Roll your own: give instructions, test verification, and stop conditions Upfront planning isn't dead. Taking 60 seconds to understand the problem still saves hours of refactoring. I still use /plan, especially when exploring an unfamiliar codebase and I don't know the right questions to ask yet. Getting the lay of the land before touching code is worth every second.

Eager vs. lazy loading MCP tools: which pattern do you default to? ⚡ Eager: Zero-hop calls & instant validation, but costs tokens on every turn. ⏳ Lazy: Zero context bloat (scales to 100+ tools), but adds proxy overhead. I broke down the trade-offs + demo plugin: linkedin.com/pulse/agent-plu…

We know Agents spend a ton of time idle. Some of that time is waiting for MCP tool calls. MCP Events are interesting for their potential to improve active vs idle time efficiency, for example by updating the agent on the progress of a long tool call.

The Googlebook is officially here and it includes @antigravity ...
Googlebook is officially here! I’ve been so excited to share the details with the world. Today, many of us rely heavily on laptops to get work done, but we think there is an opportunity to rethink the category to address the needs of people today. So we brought the best of ChromeOS and Android to create a new platform for laptops. Our initial focus with Googlebook is to deliver an amazing laptop that feels awesome for Android phone users. Here’s what to know about Googlebook 🧵👇

You think deleting that old, undocumented endpoint is safe? Think again. The AI agents already found it, they’re using it, and your next deployment will crash apps depending on it.

Hyrum's law in the agentic era

In 2012, Hyrum Wright codified the following observation: “With a sufficient number of users of an API, it does not matter what you promise in the contract: all observable behaviors of your system

Discover agent skills mid-session?
Can you discover skills mid-session and use them right away? Or lazy load the skills you need based on a "seed skill" that downloads the right one just-in-time? 🤔 I've been messing around with this, and wrote up some examples ... seroter.com/2026/08/31/you-c…
