Retrieve clean markdown from URLs when web_fetch fails. Converts pages via Jina AI reader service with automatic retry. Use when web_fetch or curl returns 403, blocked, paywall, timeout, JavaScript-rendering errors, or empty content or user explicitly suggests using jina.
Retrieve readable content from URLs that web_fetch cannot access. Jina AI's reader service renders JavaScript, bypasses soft blocks, and returns clean markdown.
Invoke this skill immediately when web_fetch returns:
curl -s --max-time 30 "https://r.jina.ai/TARGET_URL"
The service returns markdown with page title, body text, and preserved links.
Jina's backend has ~10% intermittent failures. Use retry logic to achieve 99%+ success:
for attempt in 1 2 3; do
result=$(curl -s --max-time 30 "https://r.jina.ai/TARGET_URL" 2>&1)
echo "$result" | grep -q "upstream connect error" || { echo "$result"; break; }
[ $attempt -lt 3 ] && sleep 1
done
Attempt this fallback before asking users to copy-paste content manually.
Jina returns structured markdown:
Title: page titleURL Source: original URLMarkdown Content: extracted body text, links preservedr.jina.ai is whitelisted in Claude container network configuration.
