We are developing an automated API documentation generator for backend engineering leads. We haven't conducted formal user interviews yet, but we have notes from sales calls and customer support chats. Please craft a preliminary proto-persona profile capturing their identity details, representative quotes, current frustrations, intended outcomes and goals, decision authority/influencers, and clear flags for unverified assumptions.

The instructions your model reads when the skill loads.
Create an initial, assumption-based persona profile that synthesizes available user research, market data, and stakeholder knowledge into a working hypothesis about your target user. Use this to align teams early in product development, guide initial design decisions, and identify gaps in understanding that require validation through research.
This is not a validated persona—it's a "proto" (prototype) persona that evolves as you learn more. Think of it as a structured placeholder that prevents design-by-committee while acknowledging you don't have all the answers yet.
A proto-persona is a lightweight, hypothesis-driven persona created from:
| Proto-Persona | Validated Persona |
|---|---|
| Created in hours/days | Created over weeks/months |
| Based on assumptions + limited research | Based on extensive user research |
| Used to align teams early | Used to guide detailed design |
| Evolves rapidly | Stable over time |
| Good enough to start | High confidence |
