Agent Skill Installer started as a by-product of another project I am working on. That project needed to install a skill reliably and easily, and the installer came out useful enough that I decided to make it available more generally.

Agent skills are useful when they are easy to try. The awkward part is usually not writing SKILL.md; it is getting the files into the right place, making the agent aware of them, and later remembering exactly what was installed.

Agent Skill Installer is a small Python tool for that part of the job. It installs Codex and Claude Code skills from GitHub, PyPI, a local checkout, or a local wheel file. Installation can be global for the current user or specific to a repository.

Backlog Atlas started from a maintainer problem I ran into when I recently started maintaining OmegaConf and Hydra again. Both projects are widely used, but they had been under-maintained for years. Over time, issues accumulated, pull requests piled up, and the backlog became hard to reason about.

With hundreds of issues and pull requests across both repositories, tackling the work directly felt almost impossible. Backlog Atlas came from needing a way to make that backlog visible enough to act on.

This first post is about making yadan.net into a small personal website: enough structure for projects, blog, about, and contact, without turning it into a full resume or a busy homepage.
