astropy-astronomy SKILL.md skillA
astropy-astronomy from jaechang-hits/sciagent-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Core Python library for astronomy/astrophysics: units with dimensional analysis, celestial coordinate transforms (ICRS/Galactic/AltAz/FK5), FITS I/O, tables (FITS/HDF5/VOTable/CSV), cosmology (Planck18, distance/age), precise time (UTC/TAI/TT/TDB, Julian, barycentric), WCS pixel-world mapping, model fitting. For general tables use pandas/polars; for radio interferometry use CASA.
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
# Astropy — Astronomy & Astrophysics Toolkit ## Overview Astropy is the core Python package for astronomy, providing essential functionality for astronomical research: unit-aware calculations, celestial coordinate transformations, FITS file I/O, cosmological calculations, precise time handling, tabular data operations, and WCS image coordinate mapping. ## When to Use - Converting between celestial coordinate systems (ICRS, Galactic, FK5, AltAz) - Working with physical quantities and units (Jy→mJy, parsec→km, spectral equivalencies) - Reading, writing, or manipulating FITS files (images and tables) - Cosmological calculations (luminosity distance, lookback time, comoving volume) - Precise time handling with multiple scales (UTC, TAI, TT, TDB) and formats (JD, MJD, ISO) - Cross-matching astronomical catalogs by sky position - WCS transformations between pixel and world coordinates - For **general tabular data**: use pandas or polars instead - For **radio interferometry**: use CASA instead ## Prerequisites ```bash pip install astropy # Core package pip install astropy[all] # With optional dependencies (regions, photutils, etc.) …

How to install
mdr add jaechang-hits/sciagent-skills/astropy-astronomy@sha256:5842dac588393a4eThe line at the top of this page pins the label git:20260428.81ea2d2, 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.
