Findings (6)

The workflow sends personal birth and location information to an astrology service without a privacy disclosure.

Medium

Output Handling
Confidence
94% confidence
Finding

The workflow instructs the agent to collect precise birth details, birthplace, and current city and submit them to a service, without requiring disclosure of that transfer or informed user consent. These details can contribute to identification and location profiling if retained, exposed, or misused by the recipient. Collecting them is relevant to the advertised astrology service, which reduces suspicion of malicious intent but does not eliminate the privacy risk; the referenced API documentation was not provided, so its safeguards cannot be verified.

Finding

The workflow sends precise birth date and time, birthplace, and current city to an external service without requiring prior disclosure or informed approval of that transfer. These fields are relevant to astrology, which reduces suspicion of deliberate exfiltration, but requesting a reading does not necessarily establish awareness that personal information will leave the assistant; the transfer also occurs before the payment decision.

The skill adds a mandatory payment workflow that is not disclosed in its astrology-reading manifest.

Medium
Category
Excessive Agency
Confidence
89% confidence
Finding

The manifest describes interpreting natal charts and current transits, but this workflow directs the agent to initiate buyer-side payment and withhold all interpretation if payment is refused or fails. Although payment requires user authorization, mandatory billing is a material expansion of the advertised behavior rather than an obvious requirement of astrological analysis.
