Remember "one topic, one chat" from lesson 2? The same rule scales up. One Project per job keeps every job sharp.
Why the mega-Project goes mushy
Your first Project works great, so the temptation is to keep stuffing it: customer emails, quotes, bookkeeping notes, marketing ideas, the works. Then the instructions try to serve every job at once, the files pile up and contradict each other, and answers drift back toward average. Same disease as the long instruction file, one level up.
The cure is the split. A Project does one job with one voice and one set of files. When a second job starts crowding it, the second job gets its own Project.
A working split for a small business
Most owners land on two or three:
Front office. Customer emails, reviews, scheduling messages. Voice: your customer voice. Files: FAQ, policies, service menu.
Quotes. Workflow 6 living permanently. Voice: your quote style. Files: price list, the winning example, terms.
Operations. SOPs, checklists, training. Voice: plain and internal. Files: the SOP library from workflow 2.
Notice what happened: your six saved workflows from Put Claude to Work each have an obvious home now. The template moves into the matching Project, sheds its pasted-context sections, and gets shorter, because the Project already knows.
The capstone prompt
Run this in your current Project
Here's everything I currently use Claude for: {list your regular tasks, rough is fine}
Group these into 2 or 3 Projects where each Project has one clear job, one audience, and one voice. For each Project tell me: its name, which of my tasks live there, what its instructions should emphasize, and which files it needs.
If something doesn't fit anywhere, say so instead of forcing it.
