This report does not block or authorize the manifest or ZIP.

All 65 external-command alerts are false positives caused by Markdown backticks and code fences; no Ruby or shell backtick execution exists. The three hardcoded URLs point to official Slack properties and match the connector's declared purpose. The example exposes posting to every authenticated caller, enabling unauthorized Slack messages under the configured workspace credential.

Risk findings

Confirmed security concerns are separated from items that still need review.

Confirmed security concerns (1)

RISK-001 High
SKILL.md:209-215
Slack Posting Lacks Role Authorization
The example rejects anonymous callers but lets every authenticated caller post arbitrary text through the shared bot or user credential.
Lines 209-215 check only caller anonymity before using the shared Slack token; no role, channel, or message authorization is enforced.

Remediation

Suggested fixes recorded by this audit. Applying them is the maintainer’s responsibility.

  1. FIX-001
    High
    The postSlackMessage example permits every non-anonymous caller to send messages with the shared Slack credential.
    Require an explicit sender permission before posting, restrict allowed channels, validate message limits, and add rate controls.
