Project context

Context pasted into every new chat is paid for again in every chat, and drifts each time it is retyped. Written once as instructions, it costs nothing to bring along and stays the same.

Collect

From this conversation, gather what the user keeps supplying: who they are and what they work on, the audience, rules and constraints, tone and format preferences, terms and names, recurring reference material. Ask one question at most, and only for something essential that isn't in the conversation.

Write two things, in the user's language

1. Instructions, in one code block, under 250 words: short imperative lines grouped as Context, Always, Never and Output. Keep only what changes the answers. No pleasantries, no restating what Claude does anyway.
