A guide for running Kaggle competitions, an online platform where people build models against shared datasets, and organizing research in a searchable NotebookLM knowledge base.

In plain words
What is it for?
Use it to plan a competition, study top solutions, explore features and models, track Stage 1 and Stage 2 rules, and build a competition reference library.
Why use it?
It reduces repeated research and keeps rules, winning approaches, feature ideas, and submission details together for quick reference.

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

kaggle-competition-best-practices scanned grade A with 1 finding 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 11d 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.

Runs shell commandslowCapability

Expected in a hook, worth knowing in a rule or an instructions file.

Kaggle竞赛最佳实践与知识库管理

Problem

Kaggle竞赛涉及大量领域知识、获胜技巧和策略。每次竞赛都重新学习效率低下。需要:

  • 系统化的竞赛工作流程
  • 可复制的获胜方案
  • 竞赛知识的快速查询
  • 为每个竞赛建立RAG知识库

Context / Trigger Conditions

使用此技能当:

  • 开始新的Kaggle竞赛项目 - 建立完整工作计划
  • 查询竞赛策略 - 提问: "这个竞赛的最佳实践是什么?"
  • 分析获胜方案 - 需要理解top方案的思路
  • 特征工程困惑 - 需要有效的特征灵感
  • 提交策略 - Stage1/Stage2规则和策略
  • 创建竞赛知识库 - 为新竞赛整理资料

Solution

Phase 1: 竞赛规划与知识库建立

1.1 创建竞赛NotebookLM知识库

为每个竞赛创建独立的NotebookLM notebook用于RAG查询:

# 创建新notebook
notebooklm create "{竞赛名称} 竞赛资料"

# 记录notebook ID
notebooklm list | grep "{竞赛名称}"
1.2 收集和上传资料

爬取并整理以下内容上传:

必须上传的资料:

  • 官方规则和数据说明
  • 论坛置顶讨论
  • TOP20高赞Notebooks摘要
  • 获奖方案解析

资料整理模板:

# {竞赛名称} - 论坛讨论

## 置顶/官方讨论
- 竞赛规则更新
- 数据发布通知
- 重要时间节点

## 热门讨论
- 按投票排序的TOP20

## 技术讨论
- 数据质量问题
- 特征工程技巧
- 模型架构

---

# {竞赛名称} - Notebooks分析

## TOP30 Notebooks
## 技术栈统计
## 获奖方案深度解析

---

# {竞赛名称} - 竞赛指南

## 任务理解
## 数据结构
## 评估指标
## 提交规则(Stage1/Stage2)
## 关键时间节点
## 最佳实践

上传命令:

notebooklm source add 论坛.md -n {notebook_id} --title "论坛讨论"
notebooklm source add notebooks.md -n {notebook_id} --title "Notebooks"
notebooklm source add guide.md -n {notebook_id} --title "竞赛指南"
1.3 获取Notebooks列表(推荐方法)

首选方法: Kaggle CLI

# 安装kaggle CLI(如果未安装)
pip install kaggle

# 配置API密钥
# 从 https://www.kaggle.com/settings 下载kaggle.json
# 放置在 ~/.kaggle/kaggle.json

# 获取竞赛notebooks列表(按投票排序)
kaggle kernels list --competition {competition-slug} --sort-by voteCount --page-size 50

# 示例
kaggle kernels list --competition march-machine-learning-mania-2026 --sort-by voteCount --page-size 50
kaggle kernels list --competition vesuvius-challenge-surface-detection --sort-by voteCount --page-size 50

优势:

  • ✅ 无需登录
  • ✅ 数据结构化(包含投票数、作者、更新时间)
  • ✅ 100%可靠
  • ✅ 可排序和分页

备用方法: Playwright爬虫 ⚠️

  • 仅当kaggle CLI不可用时使用
  • 可能需要登录
  • 参见 discover-undocumented-web-apis skill
1.4 批量下载和上传Notebooks(完整工作流)

问题: 直接上传Kaggle notebooks到NotebookLM会失败

  • .ipynb.Rmd 文件返回 400 Bad Request
  • NotebookLM只支持: .md, .txt, .pdf, .docx, .xlsx 等格式

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.
