Git tells you what changed. Causari tells you why.
AI coding agents are becoming good enough to touch real codebases. They can refactor files, write tests, change architecture, move logic around, and sometimes modify more code in ten minutes than a human would in an afternoon. That is powerful. But it creates a new debugging problem. Git can tell you what changed . When an AI agent was involved, you often need to know something deeper: Why did this change happen? Which prompt caused this line? Which model produced it? What files did the agent read before writing it? What later changes depended on this agent action? That is the problem I wanted to solve with Causari . Causari is a local CLI for intent-addressable code . It records AI agent actions as causal events: prompts, models, reads, writes, diffs, reasoning, cost, and relationships between actions. The goal is simple: Git tracks bytes. Causari tracks intent and causality. Repository: https://github.com/croviatrust/causari Website: https://causari.dev The problem When a human developer changes code, there is usually some context. A commit message. A pull request. A ticket. A discussion. A design decision. With AI coding agents, the workflow is different. You ask something like this: Refactor the auth flow and add JWT refresh logic. The agent reads files, makes assumptions, writes code, maybe fixes tests, maybe changes something unrelated, then moves on. At the end, you have a diff. But the diff does not tell the full story. A suspicious line appears in auth.ts . Git can show when the line appeared. But Git cannot answer: which prompt produced this exact line? what completion did it come from? did the agent read the right files first? was this part of the original request or an accidental side effect? if I revert this, what downstream work am I also undoing? That gap becomes bigger as agents become more autonomous. The more work agents do, the more we need provenance. Not only code provenance. Intent provenance. The idea: intent-addressable code Causari treats an

I built on-device workout rep counting in Flutter — here's what actually worked
I'm building TrainWiz , a Flutter app that turns real exercise into a pet-raising game: you do squats or push-ups, your phone counts the reps, and a little creature levels up and evolves. The core technical problem sounds trivial and absolutely is not: count reps from the camera, on-device, without uploading a single frame. Here's what broke along the way, and what finally worked. Why on-device Two reasons: privacy and latency. A fitness camera that streams your body to a server is a non-starter for most people, and rep feedback has to feel instant or the whole "game" loop dies. So everything runs locally with tflite_flutter + an on-device pose model — no footage ever leaves the phone. Naive attempt #1: joint-angle thresholds The obvious approach: track the knee angle, count a rep when it dips below X° and comes back up. // looks fine in a demo, dies in the real world final kneeAngle = angleBetween ( hip , knee , ankle ); if ( ! _down && kneeAngle < 100 ) _down = true ; if ( _down && kneeAngle > 160 ) { reps ++ ; _down = false ; } It demos beautifully. Then real users prop the phone on the floor, stand at an angle, and it falls apart. The trap: a phone camera gives you 2D pose. A "120° knee angle" flattens completely depending on where the camera sits — the same squat reads as 90° or 150° purely from perspective. Lifting to 3D via the model's z doesn't save you either; monocular z is noisy enough that the angle jitters across your threshold and double-counts. Naive attempt #2: a "body-line" gate Next idea: figure out which exercise you're doing so I can pick the right signal. Standing (squat) vs. horizontal (push-up) should be easy — just check if shoulder, hip and heel form a straight line, right? Wrong, again for the 2D reason. In a real push-up shot from the front-corner, shoulder–hip–heel are not collinear on the image plane — perspective bends them. I gated push-up counting on "body is a straight line" and it would just... stop counting mid-set. Nothing is more
