This looks really great on first glance - design is good, implementation is solid, tests and documentation look great.

Looks like a couple of mypy failures in the tests at the moment:

  mypy sqlite_utils tests

sqlite_utils/db.py:543: error: Incompatible types in assignment (expression has type "type[Table]", variable has type "type[View]")  [assignment]
tests/test_lookup.py:156: error: Name "test_lookup_new_table" already defined on line 5  [no-redef]
Found 2 errors in 2 files (checked 54 source files)
Error: Process completed with exit code 1.

Apologies - I pushed a fix that addresses the mypy failures.

Also tested this manually like so:

sqlite-utils create-table strict.db strictint id integer size integer --strict
sqlite-utils create-table strict.db notstrictint id integer size integer         
sqlite-utils install sqlite-utils-shell
sqlite-utils shell strict.db                                             

Attached to strict.db
Type 'exit' to exit.
sqlite-utils> insert into strictint (size) values (4);
1 row affected
sqlite-utils> insert into strictint (size) values ('four');
An error occurred: cannot store TEXT value in INTEGER column strictint.size
sqlite-utils> insert into notstrictint (size) values ('four');
1 row affected
sqlite-utils> commit;
Done
