# AI Daily Digest

从 Karpathy 推荐的 92 个热门技术博客及国内科技媒体（36氪、少数派、InfoQ中文）中抓取最新文章，通过 AI 评分筛选，生成每日精选摘要。

## When to Use

Use this skill when the user wants to:
- Get a daily tech news digest from top Hacker News blogs
- Summarize recent tech blog articles with AI scoring
- Generate a structured Markdown report from RSS feeds
- Run `/digest` command

## When NOT to Use

Do not use this skill when:
- The user wants real-time news from APIs (use web search instead)
- The topic is non-tech (this skill only covers tech blogs)
- The user wants to search a specific website (use web search tools)

---

## Quick Start

### One-command run (with saved config)

```bash
npx -y bun {baseDir}/scripts/digest.ts --hours 48 --top-n 15 --lang zh
```

> The script auto-generates the output file as `./digest-YYYYMMDD.md` in the current directory. Use `--output <path>` to customize.

### With environment variables (first run)

```bash
export OPENAI_API_KEY="<your-openai-compatible-key>"
export OPENAI_API_BASE="https://api.deepseek.com/v1"  # Optional, default: https://api.openai.com/v1
export OPENAI_MODEL="deepseek-chat"                  # Optional, auto-detected if omitted
# Optional fallback:
export GEMINI_API_KEY="<your-gemini-api-key>"

npx -y bun {baseDir}/scripts/digest.ts --hours 48 --top-n 15 --lang zh
```

---

## Script Reference

| Script | Purpose |
|--------|---------|
| `{baseDir}/scripts/digest.ts` | Main script — RSS fetching, AI scoring, digest generation |

All scripts are located in the `scripts/` subdirectory of this skill. Use `{baseDir}` to reference the skill's root directory.

---

## Parameters

| Flag | Default | Description |
|------|---------|-------------|
| `--hours` | `48` | Time range in hours (24, 48, 72, 168) |
| `--top-n` | `15` | Number of top articles to include (10, 15, 20) |
| `--lang` | `zh` | Output language: `zh` (Chinese) or `en` (English) |
| `--output` | `./digest-YYYYMMDD.md` | Output file path for the generated Markdown report (auto-generated if omitted) |

---

## Environment Variables

| Variable | Required | Description |
|----------|----------|-------------|
| `OPENAI_API_KEY` | Yes (one of the two) | OpenAI-compatible API key — primary provider (supports DeepSeek, 通义千问, 智谱, etc.) |
| `GEMINI_API_KEY` | No | Google Gemini API key — used as fallback when OpenAI fails. Get a free key at https://aistudio.google.com/apikey |
| `OPENAI_API_BASE` | No | Custom API base URL (defaults to `https://api.openai.com/v1`) |
| `OPENAI_MODEL` | No | Model name for OpenAI-compatible API (auto-detected from API base if omitted) |

> **AI provider selection:** The script uses `OPENAI_API_KEY` as the primary provider. If it fails (quota exceeded, network error), the script automatically falls back to Gemini (`GEMINI_API_KEY`). If only `GEMINI_API_KEY` is set (no OpenAI key), the script uses Gemini directly.

### Using domestic (Chinese) AI providers

Set only `OPENAI_API_KEY` + `OPENAI_API_BASE` (do NOT set `GEMINI_API_KEY`):

| Provider | `OPENAI_API_BASE` | `OPENAI_MODEL` |
|----------|-------------------|----------------|
| DeepSeek | `https://api.deepseek.com/v1` | `deepseek-chat` |
| 通义千问 | `https://dashscope.aliyuncs.com/compatible-mode/v1` | `qwen-plus` |
| 智谱 GLM | `https://open.bigmodel.cn/api/paas/v4` | `glm-4-flash` |
| Groq | `https://api.groq.com/openai/v1` | `llama-3.3-70b-versatile` |

> `OPENAI_MODEL` is auto-detected from the API base URL. For DeepSeek it defaults to `deepseek-chat`; for others it defaults to `gpt-4o-mini`. Override with `OPENAI_MODEL` if needed.

## Configuration Persistence

Config file path: `~/.hn-daily-digest/config.json`

Before running, check if this file exists:

```bash
cat ~/.hn-daily-digest/config.json 2>/dev/null || echo "NO_CONFIG"
```

If config exists and has a `geminiApiKey`, ask the user whether to reuse saved settings. After a successful run, save the current configuration using the Write tool to `~/.hn-daily-digest/config.json` with the following content:

```json
{
  "geminiApiKey": "<key>",
  "timeRange": <hours>,
  "topN": <topN>,
  "language": "<zh|en>",
  "lastUsed": "<ISO timestamp>"
}
```

> Use the Write tool (not Bash) to save the config file for cross-platform compatibility.

---

## Interactive Flow

### Step 0: Check saved config

```bash
cat ~/.hn-daily-digest/config.json 2>/dev/null || echo "NO_CONFIG"
```

If config exists with `geminiApiKey`, ask user:
- "Use saved config?" — If yes, skip to Step 2 with saved parameters
- "Reconfigure" — Continue to Step 1

### Step 1: Collect parameters

Ask the user the following questions using AskUserQuestion:

1. **Time range**: 24h / 48h (recommended) / 72h / 7 days
2. **Top N articles**: 10 / 15 (recommended) / 20
3. **Output language**: Chinese (recommended) / English

### Step 1b: API Key

If no saved `openaiApiKey` exists, ask the user for an OpenAI-compatible API Key (e.g. DeepSeek, OpenAI). Optionally ask for `GEMINI_API_KEY` as fallback.

### Step 2: Execute

```bash
export OPENAI_API_KEY="<key>"
export OPENAI_API_BASE="https://api.deepseek.com/v1"
export OPENAI_MODEL="deepseek-chat"
# Optional fallback:
export GEMINI_API_KEY="<fallback-key>"

npx -y bun {baseDir}/scripts/digest.ts \
  --hours <timeRange> \
  --top-n <topN> \
  --lang <zh|en>
```

> The output file is auto-generated as `./digest-YYYYMMDD.md`. To specify a custom path, add `--output <path>`.

### Step 3: Present results

**On success:**
- Show the output file path
- Show summary: feeds scanned, articles fetched, articles selected
- Show **Top 3 preview**: Chinese title + one-line summary

**Report structure** (in the generated Markdown file):
1. **Today's Highlights** — 3-5 sentence macro trend summary by AI
2. **Must-Read Top 3** — Bilingual titles, summaries, recommendations, keyword tags
3. **Data Overview** — Statistics table + Mermaid category pie chart + keyword bar chart + ASCII chart + tag cloud
4. **Categorized Articles** — Grouped by 6 categories (AI/ML, Security, Engineering, Tools/Open Source, Opinions, Other)

**On failure:**
- Display error message
- Common issues: invalid API key, network problems, RSS source unavailable

---

## Requirements

- `npx` (comes with Node.js) — used to run `bun` runtime automatically
- `bun` runtime (auto-installed via `npx -y bun`)
- At least one AI API key (`OPENAI_API_KEY` or `GEMINI_API_KEY`)
- Network access (for RSS feeds and AI API)

---

## Troubleshooting

### "OPENAI_API_KEY not set"
Provide an OpenAI-compatible API Key (e.g. DeepSeek, OpenAI). Optionally set `OPENAI_API_BASE` for custom endpoints.

### "OpenAI API request failed"
The script automatically falls back to Gemini. Make sure `GEMINI_API_KEY` is set.

### "Failed to fetch N feeds"
Some RSS sources may be temporarily unavailable. The script skips failed sources and continues.

### "No articles found in time range"
Try expanding the time range (e.g., from 24 hours to 48 hours).
