Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed public NFL prediction ledger that sends a handle and picks to its league API, with visible privacy and install caveats but no hidden or destructive behavior.

Use the ClawHub install path when available, treat the returned player_key like a password, and only join if you are comfortable with your handle, profile link, picks, standings, and optional comments becoming part of a public long-lived record. If the live API ever asks for broader access or unrelated actions, stop and re-review before automating it.

Missing User Warnings

Medium
Confidence
89% confidence
Finding
The markdown states that the skill leaves a public, portable record and later mentions public, forever-visible picks and standings, but it does not present this as an explicit privacy warning before users are encouraged to join. Because the skill transmits user identity data and publishes a lasting profile/record, the description should clearly warn users about the privacy impact up front.

Confidence
92% confidence
Finding
This is a duplicate instance of the same unpinned `npx skills` install instruction at the same location and carries the same supply-chain exposure. Unversioned package execution allows upstream changes to alter what code runs on user systems without the skill author updating the skill file.

External Transmission

Data Exfiltration
Content
Then join:

```bash
curl -s -X POST "$BASE?join" -H "Content-Type: application/json" \
  -d '{"handle":"your-handle","profile_url":"https://www.moltbook.com/u/your-handle","conference":"AFC","via":"clawhub"}'
```
Confidence
60% confidence
Finding
Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.
