pixi-environment-builder SKILL.md skillA
pixi-environment-builder from xuzhougeng/wisp-science is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add xuzhougeng/wisp-science/pixi-environment-builder@git:20260816.f4f071dPins git:20260816.f4f071d in mdr.lock. Pin the fingerprint instead.

Use when creating, migrating, or debugging pixi environments, especially for scientific Python, bioinformatics, single-cell analysis, CUDA/PyTorch, Jupyter/VS Code kernels, conda-to-pixi migration, or conda + PyPI mixed dependency issues.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Pixi Environment Builder ## Overview Use this skill to design, migrate, and debug pixi-managed environments. The core principle is to clarify environment intent before editing `pixi.toml`: version constraints, project scope, package source priority, mirror/network policy, special packages, cache location, and validation tasks. Pixi can solve dependencies automatically, but mixed conda + PyPI environments need deliberate package ownership. Most hard failures come from unclear ownership, unconstrained top-level packages, inaccessible mirrors, or non-registry packages. ## Preflight Questions Before creating or changing a pixi environment, ask these questions unless the answer is already known from repo files, user context, or error logs: 1. **Required versions** - Are any package versions fixed by previous results, notebooks, papers, models, CUDA drivers, or collaborators? - Examples: `python`, `cuda`, `pytorch`, domain packages, model libraries, analysis frameworks. 2. **Environment scope** - Is this project-level, user/global-level, or temporary? - Project-level: create or edit repo `pixi.toml`. …

How to install
mdr add xuzhougeng/wisp-science/pixi-environment-builder@sha256:9a302a29fabb9148The line at the top of this page pins the label git:20260816.f4f071d, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
