Some more thoughts from last week’s open space gathering on the future of software development in the age of AI. I haven’t attributed any comments since we were operating under the Chatham House Rule, but should the sources recognize themselves and would like to be attributed, then get in touch and I’ll edit this post.

Context Engineering for Coding Agents
The number of options we have to configure and enrich a coding agent’s context has exploded over the past few months. Claude Code is leading the charge with innovations in this space, but other coding assistants are quickly following suit. Powerful context engineering is becoming a huge part of the developer experience of these tools. […]
Fragments: February 4
I’ve spent a couple of days at a Thoughtworks-organized event in Deer Valley Utah. It was my favorite kind of event, a really great set of attendees in an Open Space format. These kinds of events are full of ideas, which I do want to share, but I can’t truthfully form them into a coherent […]
Excessive Bold
I’m increasingly seeing a lot of technical and business writing make heavy use of bold font weights, in an attempt to emphasize what the writers think is important. LLMs seem to have picked up and spread this practice widely. But most of this is self-defeating, the more a writer uses typographical emphasis, the less power […]
Assessing internal quality while coding with an agent
There’s no shortage of reports on how AI coding assistants, agents, and fleets of agents have written vast amounts of code in a short time, code that reportedly implements the features desired. It’s rare that people talk about non-functional requirements like performance or security in that context, maybe because that’s not a concern in many […]

My colleagues here at Thoughtworks have announced AI/works™, a platform for our work using AI-enabled software development. The platform is in its early days, and is currently intended to support Thoughtworks consultants in their client work. I’m looking forward to sharing what we learn from using and further developing the platform in future months. ❄ ❄ ❄ ❄ ❄ […]
LLMs and the what/how loop
All this matters even when we use LLMs and prompt them. I recently experimented with writing a miniature object store inspired by the MinIO codebase. When I asked the LLM to derive the implementation for MinIO, it produced something that was too procedural and harder to understand. When I wrote it myself, step by step, […]
Stop Picking Sides
I like Agile. I like discipline. I like systems that ship and systems that learn. What I don’t like: tribes. In the last couple decades, many teams camped at the ends of a spectrum: Traditional shops treated optimization as virtue and adaptation as risk. Agile shops treated adaptation as virtue and optimization as betrayal. Both […]
My favorite musical discoveries of 2025
I listen to a lot of music, it’s a constant accompaniment to my work and our evening relaxing. I don’t use streaming services, every couple of weeks I buy a bunch of digital albums and listen to them every day until we’re ready for a new batch. Here’s my favorite six from last year’s listening. […]

Anthropic report on how their AI is changing their own software development practice. Most usage is for debugging and helping understand existing code Notable increase in using it for implementing new features Developers using it for 59% of their work and getting 50% productivity increase 14% of developers are “power users” reporting much greater gains […]
