Two Small Prompt Changes Cut Claude Editing Time by 80%

A Reddit user who's been using Claude daily for six months reports that two simple structural changes to prompts cut their editing time by about 80%. The key: put the role instruction at the start and the format instruction at the end, with the actual task in the middle.

The Two Changes

1. Role instruction at the start: Not a "act like" preamble, but a direct statement. Example: You are a senior account manager handling a client complaint. The user says this shifts vocabulary, depth, and assumptions so that outputs read like they come from someone with domain experience rather than a general assistant.

2. Format instruction at the end: Specify output constraints. Example: Max 130 words, three paragraphs, professional but direct, no bullet lists. Without this, Claude defaults to long explanatory prose that requires reformatting. With it, you get exactly what you specified on the first pass.

Order Matters

Structure: role at the start, format at the end, task in the middle. The user reports that this pattern means most outputs need one round of iteration instead of three, drastically reducing editing time.

The post invites others to share similar structural tricks that consistently work for their specific use cases.
