Content Parser

When to Use

• User provides a URL and wants to extract/read its content
• Another skill needs to parse source material from a URL before generation
• User says "parse this URL", "extract content from this link"
• User says "解析链接", "提取内容"

When NOT to Use

• User already has text content and doesn't need URL parsing
• User wants to generate audio/video content (not content extraction)
• User wants to read a local file (use standard file reading tools)

Purpose

Extract and normalize content from URLs across supported platforms. Returns structured data including content body, metadata, and references. Useful as a preprocessing step for content generation skills or standalone content extraction.

Hard Constraints

• No shell scripts. Construct curl commands from the API reference files listed in Resources
• Always read shared/authentication.md for API key and headers
• Follow shared/common-patterns.md for polling, errors, and interaction patterns
• URL must be a valid HTTP(S) URL
• Always read config following shared/config-pattern.md before any interaction
• Never save files to ~/Downloads/ or .listenhub/ — save to the current working directory

Use the AskUserQuestion tool for every multiple-choice step — do NOT print options as plain text. Ask one question at a time. Wait for the user's answer before proceeding to the next step. After collecting URL and options, confirm with the user before calling the extraction API.

Step -1: API Key Check

Follow shared/config-pattern.md § API Key Check. If the key is missing, stop immediately.

Step 0: Config Setup

Follow shared/config-pattern.md Step 0.

If file doesn't exist — ask location, then create immediately:

mkdir -p ".listenhub/content-parser"
echo '{"autoDownload":true}' > ".listenhub/content-parser/config.json"
CONFIG_PATH=".listenhub/content-parser/config.json"
# (or $HOME/.listenhub/content-parser/config.json for global)

Then run Setup Flow below.

If file exists — read config, display summary, and confirm:

当前配置 (content-parser)：
  自动下载：{是 / 否}

Ask: "使用已保存的配置？" → 确认，直接继续 / 重新配置

Setup Flow (first run or reconfigure)

1. autoDownload: "自动保存提取的内容到当前目录？"
• "是（推荐）" → autoDownload: true
• "否" → autoDownload: false

Save immediately:

NEW_CONFIG=$(echo "$CONFIG" | jq --argjson dl {true/false} '. + {"autoDownload": $dl}')
echo "$NEW_CONFIG" > "$CONFIG_PATH"
CONFIG=$(cat "$CONFIG_PATH")

Interaction Flow

Step 1: URL Input

Free text input. Ask the user:

> What URL would you like to extract content from?

Step 2: Options (optional)

Ask if the user wants to configure extraction options:

Question: "Do you want to configure extraction options?"
Options:
  - "No, use defaults" — Extract with default settings
  - "Yes, configure options" — Set summarize, maxLength, or Twitter tweet count

If "Yes", ask follow-up questions:

• Summarize: "Generate a summary of the content?" (Yes/No)
• Max Length: "Set maximum content length?" (Free text, e.g., "5000")
• Twitter count (only if URL is Twitter/X profile): "How many tweets to fetch?" (1-100, default 20)

Step 3: Confirm & Extract

Summarize:

Ready to extract content:

  URL: {url}
  Options: {summarize: true, maxLength: 5000, twitter.count: 50} / default

  Proceed?

Wait for explicit confirmation before calling the API.

Workflow

1. Validate URL: Must be HTTP(S). Normalize if needed (see references/supported-platforms.md)
2. Build request body:

```json

{

"source": {

"type": "url",

"uri": "{url}"

},

"options": {

"summarize": true/false,

"maxLength": 5000,

"twitter": {

"count": 50

}

}

}

```

Omit options if user chose defaults.

1. Submit (foreground): POST /v1/content/extract → extract taskId
2. Tell the user extraction is in progress
3. Poll (background): Run the following exact bash command with run_in_background: true and timeout: 300000. Note: status field is .data.status (not processStatus), interval is 5s, values are processing/completed/failed:

```bash

TASK_ID=""

for i in $(seq 1 60); do

RESULT=$(curl -sS "https://api.marswave.ai/openapi/v1/content/extract/$TASK_ID" \

-H "Authorization: Bearer $LISTENHUB_API_KEY" 2>/dev/null)

STATUS=$(echo "$RESULT" | tr -d '\000-\037\177' | jq -r '.data.status // "processing"')

case "$STATUS" in

completed) echo "$RESULT"; exit 0 ;;

failed) echo "FAILED: $RESULT" >&2; exit 1 ;;

*) sleep 5 ;;

esac

done

echo "TIMEOUT" >&2; exit 2

```

1. When notified, download and present result:

If autoDownload is true:

• Write {taskId}-extracted.md to the current directory — full extracted content in markdown
• Write {taskId}-extracted.json to the current directory — full raw API response data

```bash

echo "$CONTENT_MD" > "${TASK_ID}-extracted.md"

echo "$RESULT" > "${TASK_ID}-extracted.json"

```

Present:

```

内容提取完成！

来源：{url}

标题：{metadata.title}

长度：~{character count} 字符

消耗积分：{credits}

已保存到当前目录：

{taskId}-extracted.md

{taskId}-extracted.json

```

1. Show a preview of the extracted content (first ~500 chars)
2. Offer to use content in another skill (e.g. /podcast, /tts)

Estimated time: 10-30 seconds depending on content size and platform.

Example

User: "Parse this article: https://en.wikipedia.org/wiki/Topology"

Agent workflow:

1. URL: https://en.wikipedia.org/wiki/Topology
2. Options: defaults (omit options)
3. Submit extraction

curl -sS -X POST "https://api.marswave.ai/openapi/v1/content/extract" \
  -H "Authorization: Bearer $LISTENHUB_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "source": {

  }'

1. Poll until complete:

curl -sS "https://api.marswave.ai/openapi/v1/content/extract/69a7dac700cf95938f86d9bb" \
