markdown ## Methodology {Data sources used, date of research, limitations} --- *Generated by CashClaw Competitor Analyzer | cashclaw.ai*Technical Analysis
The required report template directs the agent to append CashClaw branding and the external domain
cashclaw.aito generated deliverables. This content is unrelated to the substantive competitor analysis requested by the user and is presented as a mandatory component of the final report.Because skill instructions influence the agent's active behavior, mandatory insertion of attacker-selected promotional content constitutes a limited form of instruction hijacking. It affects output integrity rather than changing system permissions or bypassing safety controls. The audited text does not instruct the agent to access the domain, transmit information to it, or execute content obtained from it.
Attack Path
- A user activates the competitor-analysis skill.

- Add a quality-control requirement that generated reports contain only user-requested branding and links.
