Polish

This skill appears coherent and low-risk: it only provides writing/style guidance for casual Polish and asks for nothing else. Things to consider before installing: (1) Privacy — any text you give the agent to rewrite may be sent to the model/service handling skills, so avoid submitting sensitive data unless you trust the environment. (2) Tone and profanity — the guidelines include casual slang and coarse words (e.g., 'zajebiście', 'do dupy'); expect the skill to produce colloquial or strong language unless you instruct it otherwise. (3) If you need formal or domain-specific Polish (legal, medical, corporate), explicitly require those constraints because the default is casual. No additional technical concerns found.
