Nothing Improves a Framework Like Building on It
Five apps filed 133 bugs against my own framework and libraries in five weeks, and thirty releases followed. What a test suite cannot find, an app built on top of it will. Thirty-one releases of my framework and libraries since October, and I planned none of them.

TfLens: My AI Observability Dashboard
I build software with AI coding agents, and every run costs tokens or dollars. TfLens is the dashboard I built to see where that money goes: per project, per phase, per model, per tool. It reads the five metrics files TechieFlow writes into every repository and turns them into nine pages: coverage, gate outcomes, harness comparison, routing and economics, misses and rework, phase effort, price providers, snapshot export. Free, live at tflens.techierathore.com, with every number next to the file it came from.

The Simulator Said 301. The Phone Said 155
Last month I counted 119 mistakes that got through because somebody checked the wrong thing. This is one more, caught in time. AI agents built the part of my library that runs a language model on the device itself, and they tested it on an iPhone simulator: 301 tokens a second. The real phone gave 155. The pretend Android phone was wrong in the other direction. Four real devices, one table of measured numbers, and what it taught me about the word "tested".
