mumax3 SKILL.md skillA
mumax3 from msjs2333/mumaxwriter.skill is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add msjs2333/mumaxwriter.skill/mumax3@git:20261031.cb6c5e4Pins git:20261031.cb6c5e4 in mdr.lock. Pin the fingerprint instead.

Write, review, debug, and parameterize MuMax3 .mx3 simulations, including geometry, materials, fields, initial states, OVF output, Python batch workflows, and paper-guided phenomenon reconstruction.
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
# mumax3 Use native MuMax3 for `.mx3` simulations. Python can handle case generation, analysis and plotting when useful; keep existing workflows unless the request calls for a change. ## Start with the requested work Read the target script and relevant task instructions. Use current source and input records to resolve parameters; generic examples and historical plans are not evidence of what ran. Do not load an entire project history for a local edit. - **Edit or generate a script:** check the identifiers and patterns you need in [api_index.md](references/api_index.md) and [api_patterns.md](references/api_patterns.md), not both files in full by default. - **Syntax uncertainty:** use [language_subset.md](references/language_subset.md) and [anti_patterns.md](references/anti_patterns.md). MuMax3 is Go-like, not full Go. Do not redeclare built-ins such as `mu0`, `t`, `m`, or `B_ext`. - **Missing/disputed API:** search [api_full.md](references/api_full.md); consult [compatibility_notes.md](references/compatibility_notes.md) and the official API for version-sensitive behavior. Do not invent identifiers. …

How to install
mdr add msjs2333/mumaxwriter.skill/mumax3@sha256:b2acdf89fbba6e33The line at the top of this page pins the label git:20261031.cb6c5e4, 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.
