TestTau

Security checks for vulnerabilities and agentic risk

Overview

TestTau is a disclosed testing helper for disposable email and webhook capture, with privacy caveats users should follow.

Install this only for testing workflows. Use private inboxes/hooks and bearer tokens for sensitive test data, do not send production secrets or PII to public captures, and require explicit confirmation before replaying requests or wiping inboxes/hooks.

Vague Triggers

Confidence
92% confidence
Finding
The default prompt uses a broad trigger phrase ('Use $testtau') while the policy enables implicit invocation, which can cause the skill to activate in contexts the user did not explicitly intend. Because this skill creates disposable inboxes and webhooks and can wait for captured data, unintended invocation could expose test traffic, emails, or webhook payloads and lead to unnecessary external actions.
