Cease-and-Desist Letter

Q: How do I know the Cease-and-Desist Letter output is good?

The skill verifies itself against its own quality checks: Names the specific conduct with dates/examples; States why it's wrongful without overstating the law; Makes a clear, bounded demand with a deadline; States only a consequence the sender would actually pursue.

Draft a firm, professional cease-and-desist letter to stop harassment, defamation, IP misuse, or unwanted contact — clear about what must stop and what happens if it doesn't. Use when asked to write a cease and desist, make someone stop [harassing/using my work/defaming me], or send a formal letter to stop. Produces a structured letter stating the conduct, why it's wrongful, the specific demand and deadline, and the consequence, plus guidance on delivery and records — flagging when the matter needs a real lawyer. Not legal advice.

What to give it

▸The conduct — what's happening (harassment, defamation, copyright/trademark misuse, breach, unwanted contact) and by whom

▸The evidence — dates, examples, and what you can document

▸What you want — stop, take down, retract, return, or no further contact

▸Relationship & history — prior warnings, any agreement/contract involved

▸Region & stakes — for tone and whether a lawyer is warranted
