PyAutoArray AGENTS.md

A repository guide for PyAutoArray, a Python package that provides data structures and numerical utilities for scientific imaging and related projects.

In plain words
What is it for?
Use it when modifying PyAutoArray code, especially arrays, grids, masks, imaging or interferometer data, inversions, convolution, documentation, or JAX-related paths.
Why use it?
It gives coding agents the project’s architecture, dependency boundaries, related repositories, and common commands so they can make changes without breaking how the packages fit together.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

PyAutoArray AGENTS.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

PyAutoArray — Agent Instructions

Canonical, agent-agnostic instructions for this repo. CLAUDE.md imports this file; any tool that does not process @-imports should read this directly.

What this repo is

PyAutoArray (package autoarray) is the low-level data-structure and numerical-utility layer: masks, arrays, (y,x) grids, imaging/interferometer datasets, inversions/pixelizations, convolution/over-sampling operators, and the grid decorators used throughout PyAutoGalaxy and PyAutoLens.

Dependency direction: autoarray depends on autonerves only. It does not import autofit, autogalaxy, or autolens — never add such an import. Shared utilities (e.g. test_mode, jax_wrapper) belong in autonerves.

  • Source siblings: PyAutoNerves (upstream). PyAutoGalaxy / PyAutoLens build directly on autoarray.
  • No _workspace, _workspace_test, or HowTo of its own. The JAX/xp path is exercised by the parity scripts in autogalaxy_workspace_test and autolens_workspace_test.
  • docs/ — Sphinx source; published to ReadTheDocs.

Architecture

  • autoarray/structures/Array2D, Grid2D, Grid2DIrregular, VectorYX2D, and the grid decorators.
  • autoarray/dataset/Imaging / Interferometer dataset containers.
  • autoarray/inversion/ — pixelizations and linear inversion machinery.
  • autoarray/operators/Convolver, over-sampling, and related operators.
  • test_autoarray/ — test suite.

Quick commands

pip install -e ".[dev]"                                  # install with dev/test extras
python -m pytest test_autoarray/                         # full test suite
python -m pytest test_autoarray/structures/test_arrays.py   # one focused test (add -s for output)
black autoarray/                                         # formatter (advisory — not gated)

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

PyAutoArray AGENTS.md is an instructions file published in the GitHub repository PyAutoLabs/PyAutoArray (10 stars, last pushed 2d ago), licensed MIT. It adds 1,452 tokens to every session, about $0.0073 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
