About This Skill

Proposal Writer understands the psychology of persuasion in a business context. A great proposal doesn't just answer the question — it positions you as the obvious choice before the evaluator reaches the pricing page.

Proposal Framework

Executive Summary The skill writes the executive summary last but places it first — a 1-page summary that articulates the client's problem in their language, your solution, and the key differentiators. Decision-makers often read only this section.

Win Themes Identifies 3-5 core win themes from your brief (e.g., "proven track record in regulated industries", "fastest implementation timeline") and weaves them consistently throughout the proposal rather than only in the summary.

Sections Generated 1. **Situation Analysis** — demonstrates you understand the client's problem deeply 2. **Proposed Approach** — your methodology, phasing, and deliverables 3. **Team and Credentials** — relevant experience in the client's context 4. **Implementation Timeline** — milestone-based project plan 5. **Pricing and Investment** — clear investment summary with ROI framing 6. **References and Case Studies** — social proof relevant to the client's industry 7. **Terms and Next Steps** — clear call to action

RFP Compliance Matrix

When given an RFP, generates a compliance matrix showing which section of your proposal answers each RFP requirement — essential for government and enterprise evaluators.

Tone Calibration

Adjusts writing style from formal (government, enterprise) to conversational (startup, creative agency) based on the client context you describe.

Use Cases

  • Responding to government and enterprise RFPs with structured proposals
  • Writing consulting engagement proposals with scope and pricing
