bytedance/agentkit-samples is a collection of examples and tutorials for Volcengine AgentKit, an AI-agent development platform for building, deploying, and operating agent applications. Developers use the samples to learn agent creation, multi-agent collaboration, memory, retrieval, MCP integrations, media generation, customer service, and other workflows. The catalogue skills provide agent workflows based on these examples.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00074 | $0.00897 |
| Opus 5 | $0.00037 | $0.00449 |
| Sonnet 5 | $0.00015 | $0.00179 |
| Haiku 4.5 | $0.00007 | $0.00090 |
Grade A, and why
byted-util-prd-developer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
PRD Developer Skill
专业的产品需求文档（PRD）开发技能，帮助产品经理系统化地输出高质量的产品需求文档。
核心功能
- 需求分析：从用户描述中提取核心需求，进行优先级排序
- PRD 文档撰写：输出结构化的产品需求文档
- 用户故事编写：按照标准格式编写用户故事和验收标准
- 页面/功能规格：定义页面结构、交互流程、状态管理
PRD 文档模板
标准前端项目 PRD 结构
# [项目名称] 产品需求文档
## 1. 项目概述
### 1.1 项目背景
### 1.2 项目目标
### 1.3 目标用户
### 1.4 成功指标
## 2. 功能需求
### 2.1 功能列表（按优先级排列）
| 功能模块 | 优先级 | 描述 | 状态 |
|----------|--------|------|------|
| ... | P0/P1/P2 | ... | 待开发 |
### 2.2 用户故事
- 作为[用户角色]，我希望[功能描述]，以便[用户价值]

## 7. 里程碑与排期
工作流程
- 接收需求：收集用户/老板的需求描述
- 需求分析：拆解需求，识别核心功能和扩展功能
- 撰写 PRD：按照上述模板结构化输出 PRD 文档
- 定义 Mock 数据：为前端开发提供 Mock API 定义
- 制定验收标准：明确功能和视觉的验收条件
- 输出产物：将 PRD 保存为
PRD.md文件
最佳实践
- 用户视角优先：所有功能描述从用户价值出发
- 明确边界：清晰定义"做什么"和"不做什么"
- 可量化指标：验收标准必须可测量、可验证
- Mock 数据先行：定义好数据结构后再开始开发
- 渐进式细化：先定义核心流程，再补充边缘场景
输出规范
- PRD 文档保存为
PRD.md - Mock API 定义保存为
mock-api.md或mock-api.json - 设计规范整合到 DESIGN.md（配合 getdesign-md 技能下载的设计系统）
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

byted-util-prd-developer is a skill published in the GitHub repository bytedance/agentkit-samples (449 stars, last pushed 3d ago), licensed Apache-2.0. It adds 74 tokens to every session and 897 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
