Content Summarizer
Transform any URL or raw text into structured, actionable content summaries using extractive summarization + AI enhancement prompts.
What This Skill Does
- Fetches any URL and extracts clean text (removes HTML, nav, scripts, ads)
- Extracts key sentences algorithmically (extractive summarization — no API needed)
- Generates metadata (title, word count, reading time)
- Outputs a structured markdown template + AI enhancement prompt ready for any LLM
The AI enhancement prompt makes the extracted content easy to summarize with MiniMax, GPT-4o, or Claude.
Quick Start
# Summarize a URL (outputs to terminal + /tmp/summaries/)
./scripts/url-to-summary.sh https://example.com/article
# Summarize text directly (from argument or pipe)
./scripts/summarize.sh "Your article text here..."
cat article.txt | ./scripts/summarize.sh
# Custom model for AI prompt
./scripts/url-to-summary.sh https://example.com --model openaiScripts
url-to-summary.sh — Full Summary from URL
./scripts/url-to-summary.sh <url> [--model minimax|openai|anthropic]Fetches URL, extracts clean text, produces:
- Extracted key sentences (extractive summarization)
- Structured markdown template (summary, tweet hook, key takeaways)
- AI enhancement prompt — copy-paste into any LLM for full summarization
- Metadata (title, word count, reading time)
Output saved to /tmp/summaries/summary-TIMESTAMP.md
summarize.sh — Summarize Text Directly
./scripts/summarize.sh "Your text..."
cat file.txt | ./scripts/summarize.shSame output as url-to-summary.sh but for raw text input.
Output Format
# Content Summary
**Source:** [url]
**Title:** [extracted or unknown]
**Stats:** ~1,200 words | ~6 min read
## Key Sentences (Extractive Summary)
[Top 15-20 most meaningful sentences from the text]
## Structured Summary Template
[TODO fields for: what, why, key points]
## Tweet Hook
[TODO: Compelling one-liner]
## Key Takeaways
1. [TODO]
2. [TODO]
3. [TODO]
## AI Enhancement Prompt
[Ready-to-use prompt with extracted text embedded]Environment Variables
| Variable | Default | Description |
|---|---|---|
OUTPUT_DIR | /tmp/summaries | Where to save summary files |
MODEL | minimax | AI model for enhancement prompt |
Use Cases
- Content repurposing: Fetch articles, extract key points, feed into content pipeline
- Research pipeline: Batch summarize 20 URLs, collect key points, synthesize insights
- Newsletter workflow: Fetch sources, generate structured summaries, assemble newsletter
- Quick reading: Extract key sentences from long articles for rapid triage
Notes
- Uses extractive summarization (algorithmically selects important sentences) — no API key needed
- AI enhancement prompt is the value-add: paste into MiniMax/GPT/Claude for full abstractive summary
- HTML extraction removes scripts, styles, nav, footer, ads — focuses on article body
- Limited to 15,000 characters of extracted text to keep context manageable
Output Format
## Summary
[2-3 paragraph summary of the content]
## Tweet Hook
> [One compelling, shareable sentence that captures the essence]
## Key Takeaways
1. [First key point]
2. [Second key point]
3. [Third key point]

MAX_TOKENS | No | 500 | Max tokens in summary output |
Usage Examples
# Summarize a blog post
./scripts/url-to-summary.sh https://yourcompetitor.com/blog/industry-trends
# Process a research paper
./scripts/summarize.sh "$(curl -sL https://arxiv.org/pdf/2301.00001.pdf | head -c 10000)"
# Quick key points for a meeting
./scripts/key-points.sh https://news.ycombinator.com/item?id=12345678
# Use with OpenClaw: feed the output directly into your workflow
SUMMARY=$(./scripts/url-to-summary.sh https://example.com/article)
echo "$SUMMARY" | ./scripts/key-points.shTips
- For better results, provide clean article URLs (avoid paywalls and heavy JS pages)
- Use
MAX_TOKENS=1000for longer, more detailed summaries - Chain with other skills: competitor-tracker alerts → content-summarizer → social posting
- The tweet hook is designed to be engaging, not just a truncated sentence
- Key points should be actionable insights, not just topic labels
Dependencies
curl— for fetching URLs- OpenClaw agent with web_fetch tool for content extraction (used internally by the agent)
