About this skill

AI Daily Digest (Claude Native Edition)

Fetch the latest articles from the 90 popular tech blogs recommended by Karpathy, score and filter them with Claude, and generate a daily curated digest.No external AI API Key required.

Default Parameters

Parameter Default Value Description
Time Range 48 hours The last two days
Curated Count 15 articles Standard recommendation
Output Language Chinese Titles and summaries translated into Chinese

Script Directory

All scripts are located in this skill's scripts/ subdirectory.

  1. Determine the directory path of this SKILL.md file as SKILL_DIR
  2. Script path = ${SKILL_DIR}/scripts/digest.ts

Execution Flow (fully automatic by default, no user input required)

Usage Notes

On each run, output at the beginning of the reply:

Step 0: Determine run parameters (automatic, no interaction)

Priority (from high to low)：

  1. Explicitly specified by the user in the message — e.g., "fetch 72 hours", "want 20 articles", "English" → use directly
  2. Saved configuration file — read ~/.hn-daily-digest/config.json, and if it exists, use the values in it directly
  3. Built-in default values — hours=48, topN=15, lang=zh
cat ~/.hn-daily-digest/config.json 2>/dev/null || echo "NO_CONFIG"

Only perform interactive parameter collection when the user's message explicitly contains words such as "reconfigure", "change parameters", or "customize". In all other cases, silently use the parameters determined by the above priority and execute directly.

Before starting execution, inform the user in one line of text of the parameters actually used, for example:

▶ 参数: 48小时 / 15篇 / 中文（来自已保存配置）

Or:

▶ 参数: 48小时 / 15篇 / 中文（默认值）

Step 1: Execute RSS fetching (--raw mode, no API Key required)

SKILL_DIR="<此 SKILL.md 文件所在目录的绝对路径>"
RAW_FILE="/tmp/hn-digest-raw-$(date +%Y%m%d%H%M).json"

npx -y bun "${SKILL_DIR}/scripts/digest.ts" \
  --raw \
  --hours <hours> \
  --output "$RAW_FILE"

Wait for execution to complete, and record statistics (number of sources, total articles, filtered articles).

Step 2: Read the article list

Use the Read tool to read $RAW_FILEto obtain the complete article JSON data.

Step 3: Claude scoring and filtering

Complete this in internal thinking; do not output the intermediate score list.

For each article, based on title + description score across three dimensions (1-10):

Dimension Scoring Criteria
relevance Practical value for tech/AI/engineering professionals, whether it solves a real problem
quality Article depth, insight, writing quality, whether it offers unique views
timeliness Current relevance, whether it reflects the latest trends or urgent topics

Also assign to each article:

  • category: ai-ml / security / engineering / tools / opinion / other
  • keywords: 2-4 keywords

Sort by relevance + quality + timeliness total score and select the Top N articles.

Step 4: Generate summaries

For each curated article, generate:

  • titleZh(Chinese mode): accurate Chinese title, retaining technical terms
  • summary: 4-6 sentence structured summary
    • Sentence 1: core problem or background
    • Sentences 2-4: main arguments, technical details, or key findings
    • Last sentence: conclusion, impact, or recommended action
  • reason: one-sentence recommendation reason ("why it's worth reading")

In English mode, titleZh keeps the original English title.

Step 5: Generate Today's Highlights

Synthesize all selected articles and write a 3-5 sentence macro trend summary:

  • Distill common themes and technology trends across articles
  • Do not enumerate articles one by one; instead distill higher-level insights
  • Concise and impactful language, aimed at technical professional readers

Step 6: Save configuration

mkdir -p ~/.hn-daily-digest
cat > ~/.hn-daily-digest/config.json << 'CONF'
{
  "timeRange": <hours>,
  "topN": <topN>,
  "language": "<zh|en>",
  "lastUsed": "<当前 ISO timestamp>"
}
CONF

Step 7: Use the Write tool to generate the Markdown report

Output path:./output/ai-daily-digest-YYYYMMDD-HHmm.md(first mkdir -p ./output）

### Step 8: 生成 PDF 报告

基于 Step 7 生成的 Markdown 文件，通过 `marked` 转 HTML + Chrome headless 打印 PDF（零额外安装）：

```bash
MD_FILE="./output/ai-daily-digest-YYYYMMDD-HHmm.md"
HTML_FILE="/tmp/ai-daily-digest-YYYYMMDD-HHmm.html"
PDF_FILE="./output/ai-daily-digest-YYYYMMDD-HHmm.pdf"

# 1. Markdown → HTML（带排版样式）
cat > "$HTML_FILE" << 'HTMLEOF'
<!DOCTYPE html>
<html lang="zh-CN">
<head>
<meta charset="UTF-8">
<style>
  body {
    font-family: -apple-system, BlinkMacSystemFont, "Segoe UI", "PingFang SC", "Hiragino Sans GB", "Microsoft YaHei", sans-serif;
    max-width: 900px; margin: 0 auto; padding: 40px 20px;
    color: #333; line-height: 1.8; font-size: 14px;
  }
  h1 { font-size: 24px; border-bottom: 2px solid #333; padding-bottom: 10px; }
  h2 { font-size: 20px; color: #1a1a1a; margin-top: 30px; border-bottom: 1px solid #ddd; padding-bottom: 6px; }

  hr { border: none; border-top: 1px solid #eee; margin: 24px 0; }
  a { color: #2980b9; text-decoration: none; }
  @media print { body { padding: 0; font-size: 12px; } h1 { font-size: 20px; } h2 { font-size: 16px; } }
</style>
</head>
<body>
HTMLEOF

npx -y marked "$MD_FILE" >> "$HTML_FILE"
echo "</body></html>" >> "$HTML_FILE"

# 2. HTML → PDF（Chrome headless）
"/Applications/Google Chrome.app/Contents/MacOS/Google Chrome" \
  --headless --disable-gpu --no-sandbox \
  --print-to-pdf="$PDF_FILE" \
  --no-pdf-header-footer \
  "file://$HTML_FILE"

Note: If the system does not have Chrome, you can use npx -y md-to-pdf "$MD_FILE" as an alternative.

Final output is two files:

  • ./output/ai-daily-digest-YYYYMMDD-HHmm.md — Markdown version
  • ./output/ai-daily-digest-YYYYMMDD-HHmm.pdf — PDF version

Environment requirements

  • bun runtime (via npx -y bun automatically installed,no pre-installation required）
  • No AI API Key required
  • Network access (needs access to RSS sources, about 30 seconds)

Troubleshooting

Issue Solution
Failed to fetch N feeds Some RSS sources are temporarily unavailable; the script will skip them, which is normal
No articles found in time range Expand the time range (e.g., 24h → 48h)
/digest command does not take effect Restart Claude Code
Need to reselect parameters Include "reconfigure" in the message to trigger interactive mode
