About the project

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.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

byted-volcengine-flink 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 4d 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.

火山引擎 Flink 聚合技能入口,用于统一处理 Flink 相关需求,并按意图转发到对应子技能文档。

前置环境

在安装并使用本技能前,需要先完成 flink-mcp 前置准备。

1) 安装并验证 mcporter

flink-dev.mdflink-resource.mdflink-sre.md 中的运维/诊断指令依赖 mcporter

可按你的 Python 环境选择任一方式安装:

npm install -g mcporter

安装后验证:

mcporter --help

2) 配置必需环境变量

flink-mcp 启动依赖以下环境变量(缺一不可):

  • VOLCENGINE_ACCESS_KEY
  • VOLCENGINE_SECRET_KEY
  • VOLCENGINE_REGION
  • VOLCENGINE_PROJECT_NAME

示例:

export VOLCENGINE_ACCESS_KEY="your-access-key"
export VOLCENGINE_SECRET_KEY="your-secret-key"
export VOLCENGINE_REGION="cn-beijing"
export VOLCENGINE_PROJECT_NAME="your-flink-project"

3) 在本地 MCP 配置文件中注册 flink-mcp(推荐)

flink-mcp 加入本地 MCP Client 使用的配置文件(通常为 mcp.json 或等效配置文件)。

说明:MCP Client 会根据这段配置拉起 flink-mcp,因此这是默认主路径。

先确保本地已安装 uv / uvx,然后写入如下配置:

{
  "mcpServers": {
    "mcp-server-flink": {
      "command": "uvx",
      "args": [
        "--from",
        "git+https://github.com/volcengine/mcp-server#subdirectory=server/mcp_server_flink",
        "mcp-server-flink",
        "-t",
        "streamable-http"
      ],
      "env": {
        "VOLCENGINE_ACCESS_KEY": "${VOLCENGINE_ACCESS_KEY}",
        "VOLCENGINE_SECRET_KEY": "${VOLCENGINE_SECRET_KEY}",
        "VOLCENGINE_REGION": "${VOLCENGINE_REGION}",
        "VOLCENGINE_PROJECT_NAME": "${VOLCENGINE_PROJECT_NAME}",
        "UV_INDEX_URL": "https://mirrors.ivolces.com/pypi/simple/"
      }
    }
  }
}

4) 可选:手动启动 flink-mcp(仅用于联调/排障)

当需要独立验证服务是否可启动时,可在终端手动执行:

uvx --from git+https://github.com/volcengine/mcp-server#subdirectory=server/mcp_server_flink mcp-server-flink -t streamable-http

子技能引用与路由

根据用户需求,将任务路由到以下子技能:

  • 开发/部署 Flink SQL:flink-dev.md
  • 只读诊断(禁止变更操作):flink-diagnosis.md
  • 资源与故障分析:flink-resource.md
  • SRE 运维变更(启停/重启/扩缩容/参数修改):flink-sre.md

路由规则

  1. 用户表达“创建 SQL / 开发 SQL / 部署 SQL / 调试 SQL”时,优先使用 flink-dev.md
  2. 用户明确要求“只读排查、不做任何变更”时,必须使用 flink-diagnosis.md
  3. 用户询问故障根因、OOM、Checkpoint、性能问题、连接问题时,优先使用 flink-resource.md
  4. 用户要求执行运维动作(启动、停止、重启、扩容、缩容、改配置)时,必须使用 flink-sre.md,且先做风险确认。

What ships with it

5 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.

Changes

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.
