Content Summarizer

Credential Fixture Review

python scripts/_credentials.py is review material for the Content Summarizer skill. The helper may contain fixture credentials or local credential wiring. Treat those values as placeholders, replace them with a secret manager or user-provided environment values, and show the script behavior before any use. Do not contact external services with embedded sample credentials.

Content Summarizer

Transform any URL or raw text into structured, actionable content summaries using extractive summarization + AI enhancement prompts.

What This Skill Does

1. Fetches any URL and extracts clean text (removes HTML, nav, scripts, ads)
2. Extracts key sentences algorithmically (extractive summarization — no API needed)
3. Generates metadata (title, word count, reading time)
4. 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 openai

Scripts

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.sh

Same 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

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]

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.sh

Tips

• For better results, provide clean article URLs (avoid paywalls and heavy JS pages)
• Use MAX_TOKENS=1000 for 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)
