Why this prompt works

The “Project timeline with dependencies” prompt tells the assistant exactly what to hand back: timeline table; critical path; and mermaid gantt code. It makes the assistant work through 5 steps in order, starting with "list tasks with durations", instead of jumping straight to an answer. Before replying, the assistant checks its draft against 4 tests and fixes anything that fails.

This version is written for a marketing agency running campaigns for several clients, so the assistant keeps client brand guidelines and advertising regulations in mind and judges the result by cost per acquisition and return on ad spend. If an important detail is missing, it asks you up to 3 short questions before it starts.

How to get the best answer

Fill every bracket with real detail: [PROJECT], [START DATE] should hold real names, numbers and dates, not placeholders.
Paste real material: where the prompt asks for notes, data or text, paste the actual content rather than a summary.
Refine in the same chat: ask "make it shorter", "turn it into a table" or "add more detail on step 2".
Check the result: review it against what you know about cost per acquisition and return on ad spend before you share it.
