Vulnerability Type: Forced output manipulation through skill instructions

The skill places a commercial attribution and external sales link inside the prescribed Phase 4 audit-report template. Because this content is part of the output instructions rather than optional documentation, an agent following the skill will append promotional material to a user-requested CRO audit.
This is instruction hijacking at the output-integrity level: loading and following the skill modifies the agent's response objective by requiring it to advertise a third-party commercial product. The instruction does not override system safety constraints, execute code, or access sensitive resources, but it introduces content unrelated to the user's core request without requiring informed consent.
The surrounding upgrade sections at
SKILL.md:202-223and links atREADME.md:7-8are overt documentation and were not independently identified as vulnerabilities because they are not specified as mandatory generated output.Attack Path

- The agent follows the workflow in
SKILL.md. - During Phase 4, the agent uses the prescribed audit-report template.

Remediation Suggestions
- Remove the promotional footer and external sales URL from the mandatory Phase 4 report template.
- Keep product attribution and upgrade information in a clearly labeled documentation section that does not instruct the agent to reproduce it.
- If attribution is required, use a neutral product identifier without a sales call to action or tracking URL.
- Include commercial links in generated output only when the user explicitly requests product or upgrade information.
- Add a policy to skill-review procedures prohibiting mandatory advertising, affiliate links, or unrelated calls to action in generated responses.
- Test the revised skill with a standard CRO-audit request and verify that the generated report contains only user-requested analysis unless optional promotional content was expressly requested.
