ai-feature-prd

生成包含评估与护栏的 AI 功能产品需求文档（PRD）

帮你把 AI 功能的产品需求写成可执行的 PRD，不只是写场景和交互，还把模型会出错的地方、评估标准、护栏和兜底流程都写清楚。适合在要设计或上线用到 model/LLM 的功能时用，避免上线后才发现模型“瞎答”带来的风险。特别之处是把产品 UX（不确定性的展示）和工程指标（eval、成本/延迟预算、fallback）同时落地。

# AI Feature PRD Skill

AI features break the normal PRD because the system is probabilistic: it will be wrong sometimes, and
the product must be designed around that, not in denial of it. This skill extends a standard PRD with
the AI-specific sections that decide whether the feature is trustworthy — the UX of uncertainty, the
eval bar, guardrails, and what happens when the model is wrong.

## Required Inputs

Ask for these only if they aren't already provided:

- **The user problem** and why an AI/probabilistic approach fits it (vs. deterministic rules).
- **What "good" looks like** to the user, and the cost of a wrong answer (low-stakes vs. high-stakes).
- **Inputs available** — context/da
