blanket-type-ignore (PGH003)

Derived from the pygrep-hooks linter.

What it does

Check for type: ignore annotations that suppress all type warnings, as opposed to targeting specific type warnings.

Why is this bad?

Suppressing all warnings can hide issues in the code.

Blanket type: ignore annotations are also more difficult to interpret and maintain, as the annotation does not clarify which warnings are intended to be suppressed.

Example

from foo import secrets  # type: ignore

Use instead:

from foo import secrets  # type: ignore[attr-defined]

References

Mypy supports a built-in setting to enforce that all type: ignore annotations include an error code, akin to enabling this rule:

[tool.mypy]
enable_error_code = ["ignore-without-code"]
