Agentic

Square Peg hosted event on June 20, 2025 where I demonstrated a basic version of my daily Agentic Coding workflow using Cline and MCP tools. What does it take to write enterprise-grade code in the AI-native era? Join Square Peg investors James Tynan and Grace Dalla-Bona for a live demo and Q&A session with three leading AI-native developers - Grant Gurvis, Listiarso Wastuargo, and Sam McLeod - and get a behind-the-curtain look at the workflows that enable them to ship faster, smarter, and cleaner code using tools like Cursor, Cline, and smolagents. ...

Picture this: A business leader overhears their engineering team discussing “vibe coding” and immediately imagines developers throwing prompts at ChatGPT until something works, shipping whatever emerges to production. The term alone—“vibe coding”—conjures images of seat-of-the-pants development that would make any CTO break out in a cold sweat. This misunderstanding is creating a real problem. Whilst vibe coding represents genuine creative exploration that has its place, the unfortunate terminology is causing some business leaders to conflate all AI-assisted / accelerated development with haphazard experimentation. I fear that engineers using sophisticated AI coding agents be it with advanced agentic coding tools like Cline to deliver production-quality solutions are finding their approaches questioned or dismissed entirely. ...

The following my workflow for agentic coding. The basic flow is Setup -> Plan -> Act -> Review and Iterate. Setup - Ensure the right rules and tools are enabled, optionally gather important documentation or examples. Plan - Build a detailed plan based off your goals, requirements and ideation with the coding agent. Act - Perform the development tasks, in phases. Review and Iterate - Review the work, update the plan and iterate as required. 🕵 Setup Ensure any directories or files you don’t want Cline to read are excluded by adding them to a .clineignore file in the root of your project. 🛠️ Tools The effective use of tools is critical to the success and cost effectiveness of agentic coding. The MCP Servers (tools) I frequently use are available here: sammcj/agentic-coding#mcp-servers ...

As agentic systems become increasingly central to modern software development, many engineers are looking to build practical skills but don’t know where to start. This guide provides a short list of pre-reading/watching and hands-on training resources to help you get started with developing with AI agents. The focus is on practical implementation for tools and methods you’re likely to use in the workplace, so you can quickly gain experience and confidence in building AI powered and agentic systems. ...

Don’t ask yourself “What if my high performing engineers spent $2k/month on agentic coding?” …ask yourself why they (and others) aren’t - and what opportunities they’re missing as a result. ...

Prompt caching is a feature that Anthropic first offered on their API in 2024. It adds a cache for the tokens used Why it matters Without prompt caching every token in and out of the API must be processed and paid for in full. This is bad for your wallet, bad for the LLM hosting providers bottom line and bad for the environment. This is especially important when it comes to Agentic coding, where there are a lot of tokens in/out and important - a lot of token reuse, which makes it a perfect use case for prompt caching. ...
