Proposal Draft From a Short Brief

Step 1: Generate the skeleton.
"Outline a proposal from a client brief, with these sections: Problem
Understanding, Approach, Scope, Timeline, Investment. For each section,
write 2-3 bullet points of what should go there based on the brief. Do
not write full prose yet. First ask me to paste the brief, then wait.
Don't start until you have it."

Step 2: Review the outline. Correct any misread requirements or add
missing constraints (budget ceiling, hard deadline, must-have tech).

Step 3: Expand to full draft.
"Expand the outline from step 1 into a full proposal draft. Problem
Understanding should mirror the client's own language back to them,
proving we listened. Approach should explain the 'how' in plain
language, no jargon. Scope should be a bulleted list of concrete
deliverables, not vague promises. Timeline should use relative phases
(Phase 1, Phase 2) not fixed dates unless I gave you a start date. For
the rate and start date, write 'TODO: rate' and 'TODO: start date' so I
can fill them in myself."

Step 4: Read the draft against the original brief line by line.
Confirm every stated requirement is addressed somewhere in Scope.
