Welcome to my digital garden – a space dedicated to exploring technology and sharing what I’ve been learning. This site reflects my passion for continuous learning and open-source software, wherein I document my journey, offer insights, and dive into miscellaneous topics that reflect my interest. My goal is to maintain a corner of the Web for self-expression focused on valuable, distraction-free content. I believe in the power of the Open Web as a platform for sharing knowledge.

♠ More and more I’ve been resorting to LLMs / Gen AI to file feature requests or issues/bugs in upstream repositories. Sometimes I get completely ignored, even when I follow the project guidelines. For example, last week I filed this...
♠ Problem statement: ship a simple change (or commit, or pull request: you name it), then wait for green CI, then remove its local branch and worktree (=clean up). It’s 2026, so we’ll codify this workflow in the form of an agent skill. I...
♠ Previously. Problem statement: a Kubernetes ARM64 node kept running an AMD64 image after I replaced the registry tag with a multi-architecture image via skopeo, due to image caching. I first mirrored only the AMD64 variant into AWS ECR...
♠ Problem statement: wait before opening an upstream Helm chart upgrade PR, without putting a timer in the PR workflow. In other words: implement dependency cooldowns1 in Kargo. A Kargo Warehouse makes newly discovered Freight...

♠ Previously. When enrolled in an OpenAI / ChatGPT plan (e.g. Pro/Plus), you may want to figure out how much weekly usage (%) you have left. I’m sure codex has an /usage or /cost command to do so, but what if I’m using a third-party...
♠ Previously. Problem statement: review an AI-written slop pull request from a teammate. We’ll use a clanker to review slop PRs. First, I invoke the /meat skill, turning the diff into a reading guide, inspired by David Crawshaw: /meat...
♠ Problem statement: split a running Pi conversation / session into a second independent one whilst keeping the original. Pi has three similarly named albeit distinct operations: /fork /clone pi --fork <path|id> /fork opens a selector...
♠ Problem statement: a code block that quotes a markdown file swallows the first closing fence it meets, which is the inner one. The ADRs and LLMs post quotes a README.md that itself contains a fenced template. Written naively:...
