SYNOPSIS: "Class 3E and while some things have changed, the class assignment is still the same: kill their teacher before the end of the year. Easier said than done since Koro Sensei's made it clear he won't go down without a fight."
SOURCES: Mentions "Assassination Classroom (2015)", "TV-14", "Animation, Comedy, Action & Adventure, and Sci-Fi & Fantasy". Mentions "The students of Class 3-E have a mission: kill their teacher bef".
Overview:
The synopsis says: Class 3E's assignment is still the same: kill their teacher before the end of the year.
Some things have changed, but the mission remains.
Koro Sensei has made it clear he will not go down without a fight.
Problem: The provided text is extremely short. It is impossible to write a 160-220 word summary using only these few sentences without inventing details.
Constraint Check: "You write ONLY verifiable facts that are explicitly supported by the provided SYNOPSIS and SOURCES. You never invent or guess... If a detail is not in the provided material, you omit it rather than guess."
Dilemma: If I follow the word count constraint (160-220 words), I must invent details. If I follow the "only verifiable facts" constraint, I cannot meet the word count.
Resolution: In strict instruction following for LLMs, the "only verifiable facts" and "never invent" instructions are usually the primary guardrails for "groundedness." However, the prompt explicitly asks for a 160-220 word summary.
Wait: Let's look at the text again.
"Class 3E and while some things have changed,
