SM Saver
Extracts, summarizes, and logs resources from social media posts or direct URLs.
Output log
Append all saved entries to ~/workspace/resources.md (create if missing).
Workflow
1. Detect source type
| Pattern | Type |
|---|---|
x.com/* or twitter.com/* | Twitter/X post |
linkedin.com/* | LinkedIn post |
| Anything else | Direct URL |
2. Fetch content
Twitter/X — use xurl:
{
"tool": "exec",
"command": "xurl read <tweet_url>"
}
Parse the JSON response:
- Extract
data.text(tweet body) - Extract
data.entities.urls[].expanded_url(linked resources, skipt.coself-references and pic.twitter.com) - Extract
data.author_idor author handle if available
LinkedIn / Direct URL — skip to step 3 directly with the URL itself as the resource.
3. Summarize each resource
For each extracted URL (or the URL itself if direct):
{
"tool": "exec",
"command": "summarize \"<url>\" --length short"
}
If summarize is not installed, fall back to:
{
"tool": "exec",
"command": "python3 -c \"\nimport urllib.request, sys\nreq = urllib.request.Request('<url>', headers={'User-Agent': 'Mozilla/5.0'})\nwith urllib.request.urlopen(req, timeout=10) as r:\n html = r.read().decode('utf-8', errors='ignore')\nimport re\ntitle = re.search(r'<title>(.*?)</title>', html, re.I)\nprint(title.group(1).strip() if title else '<url>')\n\""
}
If a URL is inaccessible (auth wall, timeout), note it as [inaccessible] and continue.
4. Append to resources.md
Format — strict, no deviation:
## {YYYY-MM-DD} · {source_label}
> {tweet text or first sentence of post — max 120 chars, truncate with …}
{For each resource:}
- [{title}]({url}) — {1-line summary, max 80 chars}
---
source_label:
- Twitter:
@{handle}if extractable, elseX - LinkedIn:
LinkedIn - Direct: domain name (e.g.
github.com)
5. Confirm to user
Respond with exactly:
💾 {N} resource(s) saved · {source_label}
{title of first resource, truncated to 60 chars}
If nothing was extractable: ⚠️ No resources found in this link.
