Security audit

Social Draftsmith

Security checks across malware telemetry and agentic risk

Overview

This is a disclosed social media drafting and publishing skill that can post publicly using configured account credentials, so it should be used only with explicit publish approval.

Install only if you want the agent to help prepare and optionally publish social posts through your own configured accounts. Keep credentials least-privileged and private, run dry-runs first, and verify the exact account, platform, text, image, and subreddit/page before allowing any live publish command.

MCP Least Privilege
Confidence
95% confidence
Finding
The skill advertises and documents executable publishing integrations that rely on environment credentials, local file handling, and network access, but it declares no corresponding permissions. That mismatch is dangerous because it obscures the skill's real capabilities from reviewers and users, increasing the chance of unauthorized posting, credential misuse, or file exfiltration if the skill is invoked in an environment where those capabilities are available.

Missing User Warnings

Medium
Confidence
83% confidence
Finding
This script performs a live publishing request to Facebook with post content and credentials as soon as it is run without --dry-run, with no interactive confirmation or explicit user-facing warning at the point of network transmission. In an approval-first social-posting skill, that weakens the intended safety boundary and increases the chance of accidental publication or unintended use of privileged page credentials.

Missing User Warnings

Medium
Confidence
90% confidence
Finding
The script performs a live post when called without --dry-run, but it contains no built-in confirmation prompt, approval token, or other user-facing safeguard before publishing. In the context of a social-posting skill, this is more dangerous because accidental or unauthorized invocation can immediately publish content to a public account, causing reputational or operational harm.
