Description: Agent guidelines lacked explicit instruction to apply @functools.cache to IO-intensive private helpers or to register their .cache_clear() in the conftest fixture — leaving both steps to tribal knowledge. Changes usethis-python-code skill (v1.6 → v1.7): New "Caching IO-intensive private helpers" section — when to apply @functools.cache (read-only, called multiple times per invocation), the three-step procedure, and common mistakes (caching side-effectful functions, omitting conftest registration). usethis-python-test skill (v1.1 → v1.2): New "Clearing functools caches between tests" section — two-step procedure for importing and registering .cache_clear() in clear_functools_caches, with explanation of why omitting it causes silent test pollution.
