Python

Favour Python 3.14+ features. Use uv for .venv management. Use uvx ty check for type checking
Type hints for all functions. Dataclasses for data structures. Pathlib over os.path. f-strings
For standalone scripts that have a few dependencies, use PEP 723 to declare dependencies in a TOML block inside # /// markers (e.g. # /// script\n# dependencies = [\n# "beautifulsoup4",\n# ]\n# ///)

Trustgrade A

passBody integrity
Whether the stored document is plausibly the kind of file the artifact declares, rather than something fetched by mistake.
passType matchnot applicable to this artifact type
Whether the artifact is really the kind of thing its metadata claims it is.
passFreshness
How long since the source repository was last pushed to.
passPrompt injection
Scans the artifact's own text for instructions aimed at your agent rather than at you.
passLicense
Whether the source repository declares an SPDX license permissive enough to redistribute.

How the grade is calculated

Each check contributes 0 points when it passes, 1 when it warns, and 2 when it fails. The total maps to a letter:

Aevery check passed
Bone warning
Ctwo warnings
Dprompt injection or body integrity failed, or three warnings
Fone of those failed, and something else is wrong

These are automated hygiene checks, not a security audit, and not a dependency or vulnerability scan. A grade of A means nothing was flagged — not that the artifact is safe.
