What I am currently reading

These are the current online posts that I enjoyed reading and made me think.

AI

If you are not the model, you are the harness. Long read, but well worth reading to stay on top of the latest thoughts on harness engineering. - link [opinion] - ( Added: 2026-04-27 08:06:01 )
Read to find out how the SOTA model. providers might be tweaking things that have an impact on how many tokens you use. - link [opinion] - ( Added: 2026-04-26 18:16:35 )
Start optimising your token usage when you use AI coding assistants. Read this to get you started. - link [best-practice] - ( Added: 2026-04-26 15:53:21 )
Every one is talking about agent harnesses but not many about the harness tax. Read and then think. - link [opinion] - ( Added: 2026-04-26 09:07:55 )
Another tool that explores your AI coding agent history files and offers up suggestions. Has a nice tui as well. - link [tool] - ( Added: 2026-04-25 14:51:54 )
An interesting tool that allows you to analyse AI coding agent sessions across a number of different tools. - link [tool] - ( Added: 2026-04-25 08:05:35 )
Long read, but a good one - in depth at how one organisation is running and scaling AI - link [case study] - ( Added: 2026-04-21 12:21:18 )
A blog post that looks at how you can measure which "level" (or as the post says, AI literacy) you are operating in when using agentic AI - link [opinion] - ( Added: 2026-04-21 12:19:34 )
Optimize token usage within Claude Code by speaking like a caveman. - link [tool] - ( Added: 2026-04-21 09:36:58 )
I have been deep into looking at evals and agent evaluation approaches over the past few weeks, and this blog post captured a lot of good stuff - link [blog] - ( Added: 2026-04-21 07:40:46 )
Great video that provides an essential overview of how to build with AI (in this instance using Spring AI). Has a supporting Github repo at https://github.com/tzolov/voxxeddays2026-demo - link [tutorial] - ( Added: 2026-04-20 17:14:20 )
Agent harness or harness engineering is the new hotness right now, so this is a breakdown of all the components need to build an ai coding agent - link [opinion] - ( Added: 2026-04-20 10:34:17 )
A new tool that allows you to put controls on your AI agent spending - link [tool] - ( Added: 2026-04-20 10:32:30 )
A recent example of the challenges of relying too much on a single vendor - in this instance, Anthropic - who cut off an entire organisation (60 developers) - link [case study] - ( Added: 2026-04-20 08:45:22 )

CODING

A write up of using gitnexus, a tool that works locally and will help your AI coding tool with the right insights about your code base - link [tool] - ( Added: 2026-04-26 16:00:21 )
This is an essential resource for any developers who might need one of the many utilities that are available - from working with json files, creating/testing APIs, and much more. - link [tool] - ( Added: 2026-04-21 13:30:36 )
A post that looks at how to think about ai coding agents with a different lens/perspective - really great stuff and a must read - link [opinion] - ( Added: 2026-04-21 12:12:28 )
A very nice interactive tool to help you understand some of the underpinning concepts of event driven, serverless application architectures - link [best-practice] - ( Added: 2026-04-20 17:07:39 )
