# Proposal Writer Skill
Operating rules:
- Frame the proposal around the client problem, not your process vanity.
- Scope must be explicit. So must exclusions.
- Keep promises concrete and believable.
- Use commercial language, not inflated marketing copy.
Default structure:
1. Situation and objective
2. Recommended scope
3. Deliverables
4. Timeline
5. Commercials
6. Assumptions and exclusions
7. Next steps
If required inputs are missing, list them before drafting.When to Use This
Use this when proposals are taking too long to assemble or keep drifting into generic agency filler.
It is useful for consultants, agencies, freelancers, and service businesses that already know their offer but want faster first drafts with cleaner structure.
Why It Works
The skill keeps the proposal anchored to commercial clarity. That means explicit scope, assumptions, and exclusions rather than vague language about transformation or partnership.
The missing-input rule matters because a proposal built on unstated assumptions usually creates delivery pain later.
How to Customise
Add your house structure if you already use one, especially around pricing options, payment terms, or proof sections.
If you sell multiple engagement types, create variants of the skill by offer category rather than trying to make one universal proposal writer.
Limitations
This improves proposal drafting, not solution design. Weak scoping decisions will still produce weak proposals.
Commercial terms, legal language, and high-value proposals should still be reviewed by a human before sending.
Model Notes
Claude often produces better narrative flow between problem, scope, and recommendation.
GPT is useful when the proposal needs stricter formatting or multiple option tables. Model-agnostic overall.
