Installation context

This report may not describe the currently installable artifact. Open the current Skill page for install guidance.

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

All 57 static alerts are false positives caused by Markdown backticks or ordinary clarification text; the cited lines contain no Ruby execution, shell substitution, or system reconnaissance. However, SKILL.md declares a read tier and default installation while exposing real-money order and DCA mutations. Publication should require corrected metadata and clear installation warnings for Trade permission and financial side effects.

Risk findings

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

Confirmed security concerns (1)

RISK-001 High
SKILL.md:10-14SKILL.md:70-78
Mutating brokerage skill labeled as read tier
Metadata sets tier to read and enables default installation, while the skill can buy, sell, cancel, replace, and schedule recurring purchases with real funds.
The metadata and command descriptions directly conflict in SKILL.md. The skill documents real account mutations that require Trade permission despite declaring a read tier.

Remediation

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

  1. FIX-001
    High
    The read-tier and default-install metadata conflicts with real-money mutation capabilities.
    Set the tier to the appropriate mutating classification and disable default installation for a skill that can place or alter brokerage orders.
  2. FIX-002
    Medium
    Order mutations have a shorter confirmation policy than recurring-investment mutations.
    Require a separate preview turn with symbol, side, quantity, price, and order identifier before every buy, sell, cancel, or replace action.
  3. FIX-003
    Medium
    Trade permission exposes sensitive account data and enables financial mutations.
    Show an installation disclosure listing accessed account data, required permissions, and the real-money effects of order and DCA commands.
