Poem

🐰 A crash in sections, now patched with care,
Guards keep empty translations from snare,
The PO loader bounces, no longer in pain,
Just skipping the void, then onward again! ✨

Check name	Status	Explanation	Resolution
Docstring Coverage	⚠️ Warning	Docstring coverage is 0.00% which is insufficient. The required threshold is 80.00%.	Write docstrings for the functions missing them to satisfy the coverage threshold.
Description check	❓ Inconclusive	The description covers the bug fix and solution but deviates from the template by omitting the structured Changes section and providing incomplete Testing section with vague test descriptions rather than specific test case details.	Follow the template structure: add a clear Changes section with bullet points, and expand Testing with specific test case descriptions or indicate tests were added to the codebase.

✅ Passed checks (1 passed)

Check name	Status	Explanation
Title check	✅ Passed	The title 'fix(cli): guard against empty translations in PO loader' directly and specifically describes the main change—adding guards to handle empty translations in the PO loader.
