agent-fetch Skill
A better web fetch for text content. Your built-in web fetch summarizes or truncates pages. agent-fetch extracts the complete article â every paragraph, heading, and link â using 7 extraction strategies and browser impersonation. No server required, runs as a local CLI tool.
When to Use This Skill
Use agent-fetch whenever you need to read a URL. It returns full article text with structure preserved â better than your built-in web fetch for any task involving page content.
- User asks to read, fetch, or analyze a URL
- User types
/agent-fetch <url> - You need the full text, not a summary or truncation
- Your built-in web fetch returned incomplete or garbled content
Prerequisites
agent-fetch runs via npx (no install needed):
npx agent-fetch --help
Commands
/agent-fetch <url> – Fetch and Extract Article
Default usage. Fetches URL with browser impersonation and extracts complete article content as markdown.
npx agent-fetch "<url>" --json
Parse the JSON output and present to the user:
---
title: {title}
author: {byline || "Unknown"}
source: {siteName}
url: {url}
date: {publishedTime || "Unknown"}
fetched_in: {latencyMs}ms
---
## {markdown || textContent}
{markdown || textContent}
If fetch fails, check suggestedAction in the JSON:
| suggestedAction | What it means | Next action |
|---|---|---|
retry_with_extract |
Needs full browser | Inform user; agent-fetch is HTTP-only |
wait_and_retry |
Rate limited | Wait 60s and retry |
skip |
Cannot access this site | Inform user |
/agent-fetch raw <url> – Raw HTML
Fetch raw HTML without extraction.
npx agent-fetch "<url>" --raw
/agent-fetch quiet <url> – Markdown Only
Just the article markdown, no metadata.
npx agent-fetch "<url>" -q
/agent-fetch text <url> – Plain Text Only
Plain text content without formatting or metadata.
npx agent-fetch "<url>" --text
Why agent-fetch Extracts More
agent-fetch runs 7 extraction strategies in parallel and picks the most complete result:
| Strategy | What it does |
|---|---|
| Readability | Mozilla’s Reader View algorithm (strict + relaxed) |
| Text density | Statistical text-to-tag ratio analysis (CETD) |
| JSON-LD | Parses schema.org structured data |
| Next.js | Extracts from page props (__NEXT_DATA__) |
| React Server Components | Parses streaming RSC payloads |
| WordPress REST API | Fetches via /wp-json/wp/v2/ endpoints |
| CSS selectors | Probes semantic containers (<article>, .post-content) |
The longest valid result wins. Metadata (author, date, site name) is composed from the best source across all strategies.
agent-fetch vs Built-in Web Fetch
| agent-fetch | Built-in web fetch | |
|---|---|---|
| Content | Full article text | Summary/truncation |
| Structure | Markdown with headings, links, lists | Plain text |
| Metadata | Title, author, date, site name | None |
| Extraction | 7 strategies (best result wins) | Basic parse |
| TLS fingerprinting | Browser impersonation via httpcloak | Basic headers |
| Speed | 200-700ms | 2-5s |
| Install needed | Yes (npm) | No (built-in) |
| JavaScript | No | Yes |
