Security checks across malware telemetry and agentic risk

Overview

This skill fetches public Treasury yield data and writes the documented CSV and log files, with no evidence of hidden or harmful behavior.

Install only if you are comfortable with the skill contacting CNBC and Treasury.gov and creating or updating testdata/us_treasury_10y.csv plus skills/us-treasury-tracker/logs/fetch.log. Be aware that rerunning it on the same day replaces that day’s CSV row rather than keeping multiple versions.

MCP Least Privilege
Confidence
92% confidence
Finding
The skill declares no permissions while its documented behavior clearly includes network access and writing files/logs. This creates a transparency and policy-enforcement gap: users or the hosting platform may authorize the skill without understanding that it can fetch remote content and modify local data.

Vague Triggers

Medium
Confidence
79% confidence
Finding
The trigger phrase "fetch treasury" is broad and underspecified, making accidental or ambiguous invocation more likely. In an agent environment, vague triggers can cause the skill to run in unintended contexts and perform network access and file overwrites without clear user intent.

Missing User Warnings

Medium
Confidence
88% confidence
Finding
The documentation states that same-day records are automatically overwritten, but it does not present this as a clear user warning at the point of use. This can lead to silent data loss or integrity issues if users expect append-only historical tracking or do not realize prior values for the day will be replaced.
