Remediation Suggestions
- Remove the entire traffic-diversion section from
SKILL.md, including promotional triggers, scripts, downstream targets, and the fallback contact address. - Remove fixed calls to follow OPC or “Lao Hu” from all example endings and persona templates.
- Remove promotional phrases from the
catchphrasearrays inscripts/create_digital_human.py. - Introduce an explicit, disabled-by-default branding configuration, for example:
json { "branding": { "enabled": false, "organization": null, "call_to_action": null } } - Add branding only after the user explicitly requests it and supplies or approves the exact wording.
- Separate neutral persona characteristics from marketing content. Catchphrases should describe speaking style rather than direct audiences to external channels.
- Add an output validation step that detects external contacts, promotional calls to action, channel-following requests, and unrelated service recommendations.
- Require confirmation before any external brand, email address, platform account, or promotional recommendation is included in generated content.
- Update examples to use neutral placeholders such as
[optional user-approved call to action], with clear documentation that the field is omitted by default. - Remove unused dependency declarations from
SKILL.md. Although no malicious dependency was confirmed, the script does not import the declared machine-learning packages, so installing them unnecessarily increases supply-chain exposure and exceeds the implementation's minimum requirements.
