使用 Claude Code CLI 和 Obsidian 的每日 AI 新闻摘要——零依赖

如何用6行bash脚本、Claude Code headless模式和macOS launchd构建每日新闻研究代理。

发布于 2026年4月12日7 分钟阅读

TL;DR

一个6行的bash脚本,每天早上9:00以headless模式运行Claude Code CLI。它在11个可配置主题中搜索新闻,过滤噪音,并将格式化的markdown摘要直接写入通过iCloud同步的Obsidian vault。零依赖。总共约100行配置。

问题

作为开发者,跟踪多种技术是一项日常税收。RSS源嘈杂,Twitter浪费时间,新闻通讯在你深度专注时到达。我需要一个能我做研究的东西。

典型的解决方案是构建爬虫管道:调度器、爬虫、NLP管道、数据库、通知服务。那需要几周的工作。我想要一个下午就能完成的东西。

架构

整个系统只有4个文件和零依赖:

macOS launchd (9:00 AM daily)
  │
  └── digest.sh
        │
        └── claude -p "$(cat prompt.md)" --max-turns 20 --allowedTools Read,WebSearch,WebFetch,Write
              │
              ├── Reads topics.yaml (11 configurable topics)
              ├── WebSearch → finds news for each topic (last 24-48h)
              ├── WebFetch → reads full articles
              ├── Filters noise: old tutorials, promos, AI spam
              └── Write → saves digest to Obsidian Vault
                    │
                    └── ~/Obsidian Vault/digests/2026-04-12.md
                          │
                          └── iCloud sync → available on all devices

代码(全部)

项目刻意保持最小化。

入口:digest.sh

整个应用程序是一个6行的bash脚本:

digest.sh
#!/bin/bash
DIGEST_DIR="$HOME/Developer/news-digest"

claude -p "$(cat "$DIGEST_DIR/prompt.md")" \
  --max-turns 20 \
  --allowedTools Read,WebSearch,WebFetch,Write

关键标志:-p以headless模式运行Claude,--max-turns 20给代理足够的回合,--allowedTools限制代理只能读取、搜索和写入。

大脑:prompt.md

这里是智能所在。提示词将Claude变成新闻研究代理:

prompt.md
# News Digest Agent

You are a news research agent. Your job is to find today's most important
and interesting news for a senior frontend developer.

## Instructions

1. Read the topics file at ~/Developer/news-digest/topics.yaml
2. For EACH topic, search the web for news from the last 24-48 hours
3. Filter: only include genuinely new and noteworthy items
4. Write the digest as a markdown file to Obsidian Vault digests/YYYY-MM-DD.md
5. IMPORTANT: Use the Write tool to save the file. Do NOT output to stdout.

## Rules

- Language: Ukrainian for summaries, English for titles and technical terms
- If there's no real news for a topic — SKIP IT ENTIRELY
- Prioritize: releases > breaking changes > security > new patterns > discussions
- Max 5 items per topic, sorted by importance
- Include direct links to sources
- Skip promotional content, generic tutorials, and AI-generated spam

配置:topics.yaml

主题完全可配置——添加新主题,它就会出现在明天的摘要中:

topics.yaml
topics:
  - name: better-auth
    context: "auth library for TypeScript. New releases, breaking changes"

  - name: Next.js
    context: "GitHub issues, releases, App Router, Turbopack, performance"

  - name: SolidJS
    context: "SolidStart, releases, ecosystem, comparison with React"

  - name: Tailwind CSS
    context: "v4 updates, new utilities, plugins"

  - name: Claude AI
    context: "Anthropic announcements, Claude Code, new models, MCP, API"

  - name: GPT AI
    context: "OpenAI announcements, new models, ChatGPT features"

  - name: React
    context: "React 19+, Server Components, new patterns, ecosystem"

  - name: Apple
    context: "Hardware, software, WWDC, developer tools, Apple Intelligence"

  - name: Notable People
    context: >
      Latest tweets from: Elon Musk, Dario Amodei, Sam Altman,
      Jensen Huang, Andrej Karpathy, Simon Willison, Swyx...

  - name: AI Global
    context: "Major AI news, new models, regulations, open-source AI"

使用launchd调度

在macOS上,launchd是调度重复任务的原生方式:

~/Library/LaunchAgents/com.news-digest.plist
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN"
  "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>Label</key>
    <string>com.news-digest</string>

    <key>ProgramArguments</key>
    <array>
        <string>/bin/bash</string>
        <string>/Users/you/Developer/news-digest/digest.sh</string>
    </array>

    <key>StartCalendarInterval</key>
    <dict>
        <key>Hour</key>
        <integer>9</integer>
        <key>Minute</key>
        <integer>0</integer>
    </dict>

    <key>StandardOutPath</key>
    <string>/Users/you/Developer/news-digest/logs/stdout.log</string>
    <key>StandardErrorPath</key>
    <string>/Users/you/Developer/news-digest/logs/stderr.log</string>

    <key>EnvironmentVariables</key>
    <dict>
        <key>PATH</key>
        <string>/usr/local/bin:/opt/homebrew/bin:/usr/bin:/bin</string>
        <key>HOME</key>
        <string>/Users/you</string>
    </dict>
</dict>
</plist>

安装:launchctl load ~/Library/LaunchAgents/com.news-digest.plist。脚本每天9:00运行。

输出效果

每天早上,Obsidian vault中会出现一个新的markdown文件:

digests/2026-04-12.md
---
date: 2026-04-12

关键设计决策

  • Claude Code CLI而非API——无需管理API密钥或HTTP客户端
  • Obsidian而非邮件——摘要可搜索、可链接且永久保存
  • launchd而非cron——macOS原生调度器,自动处理错过的运行
  • YAML配置主题——新主题只需改2行
  • 跳过空主题——没有新闻=没有该部分

构建你自己的

10分钟即可运行:

  1. 安装Claude Code CLI并认证
  2. 克隆仓库:git clone https://github.com/oleksiimazurenko/news-digest
  3. 编辑topics.yamlprompt.md
  4. 编辑plist文件并launchctl load
  5. 等待9:00——或用bash digest.sh手动测试

结论

这个项目最有趣的是它没有什么。没有数据库、没有API服务器、没有Docker、没有npm包、没有Python、没有HTML解析器、没有NLP管道。

这就是用AI代理构建的样子:你定义什么哪里,代理处理怎么做。总开发时间:约2小时。
