What it does

Prd Writer is an agent skill from cafe3310/public-agent-skills. 此 Skill 指导 Gemini 将一个高阶的产品想法,通过结构化的分析与协作,转化为一份详尽、可执行的产品需求文档(PRD)。

Its SKILL.md is about 380 tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files and assets (for example `assets/PRD-Template.md` and `references/workflow-and-best-practices.md`).

It sits in Product & Project Management, covering PRD writing. The repository describes itself as: personal agent skills for better QoL. The licence is Apache-2.0.

When your agent uses it

  • Tasks that involve PRD writing

Example prompts

  • “/prd-writer”

Workflow steps

7 steps, taken from the first numbered list in SKILL.md.

  1. 收集项目信息:通过搜索,建立对项目的全面上下文认知。
  2. 筛选高阶背景与现状:提炼项目愿景、路线图和当前状态。
  3. 生成“现状分析”文档:与用户确认对项目背景的共同理解。
  4. 获取用户洞察:引导用户提供对下一迭代的具体需求和想法。
  5. 分析、对齐并生成“迭代分析”文档:评估新需求,并制定前进计划。
  6. 识别参考资料并选择模板:准备撰写 PRD 所需的所有材料。
  7. 起草 PRD:综合所有信息,生成最终的 PRD 文档。

What it can do on your machine

Read from SKILL.md and the folder at commit 6c45501. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Prd Writer loads about 375 tokens when it runs, and up to ~1.5k if it reads all its reference files. Until then it costs about 19 tokens; SKILL.md has 87 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~19
When it runs · the whole SKILL.md, loaded when a task matches
~375
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.5k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

PRD Writer Skill (产品需求文档撰写)

本 Skill 的核心目标是协助用户,将一个初步的产品构想或迭代需求,系统化地发展成一份完整的、符合业界标准的、可直接用于研发团队排期的产品需求文档(PRD)。

Agent 在此流程中扮演着商业分析师和产品经理的角色,通过一系列结构化的步骤,主动引导对话、澄清需求、对齐认知,并最终完成文档的撰写。

何时使用

当用户提出以下类型的需求时,应激活此 Skill:

  • “帮我为一个新项目/产品写一份 PRD。”
  • “我们准备开发XX功能的下一版,我们一起梳理一下需求。”
  • “我有一些关于XX产品的想法,你能帮我把它变成一个更具体的计划吗?”
  • “我们来规划一下下个季度的产品功能。”

核心工作流

本 Skill 的工作流程被定义在 references/workflow-and-best-practices.md 文件中。在开始任务前,必须首先阅读并严格遵循该文档中定义的 7 步工作流。

工作流摘要
  1. 收集项目信息:通过搜索,建立对项目的全面上下文认知。
  2. 筛选高阶背景与现状:提炼项目愿景、路线图和当前状态。
  3. 生成“现状分析”文档:与用户确认对项目背景的共同理解。
  4. 获取用户洞察:引导用户提供对下一迭代的具体需求和想法。
  5. 分析、对齐并生成“迭代分析”文档:评估新需求,并制定前进计划。
  6. 识别参考资料并选择模板:准备撰写 PRD 所需的所有材料。
  7. 起草 PRD:综合所有信息,生成最终的 PRD 文档。

可用资产 (Assets)

本 Skill 提供了一个标准的 PRD 模板,以确保产出文档的专业性和完整性。

  • 路径: assets/PRD-Template.md
  • 用途:
    • 当项目中不存在可供参考的、高质量的旧版本 PRD 时,应使用此模板作为新 PRD 的基础。
    • 在工作流的第 6 步中,根据情况决定是使用此模板还是参考项目中的现有文档。

操作指南

  1. 启动:在任务开始时,向用户确认你将使用 prd-writer Skill,并简要说明你将遵循一个结构化的流程来合作。
  2. 遵循工作流:严格按照 references/workflow-and-best-practices.md 中定义的步骤推进。不要跳过任何一步,尤其是与用户确认和对齐的步骤(第 3、4、5 步)。
  3. 使用工具:熟练运用 search_file_content、glob、read_file 和 write_file 工具来完成信息收集、分析和文档撰写。
  4. 产出文档:流程中的每一步都应有明确的文档产出(现状分析、迭代分析、最终的 PRD)。确保所有产出的文档都遵循用户的命名和存储习惯。
  5. 完成:在生成最终的 PRD 草稿后,将其交付给用户,并告知用户可以对其进行最后的审阅和修改。任务至此完成。
