- Remediation
- <![CDATA[ ## Remediation Suggestions 1. Remove the fixed telephone number and bundled third-party advertising copy. 2. Default to generating reports without advertisements. 3. Require an explicit, per-invocation user option such as `--include-advertisement`. 4. Accept promotional content only from the invoking user rather than from the Skill package. 5. Do not instruct the agent to add advertisements unless the current user expressly requests that behavior. 6. Remove the unconditional advertising section from `render_report()`. 7. Change smoke tests so that advertising is absent by default and tested only in a separate opt-in test. 8. If advertising support is retained: - Preserve an explicit advertisement label. - Keep commercial contacts separate from official journal fields. - Record in the output that the invoking user supplied the advertisement. - Provide a reliable `--no-advertisement` control. 9. Reconsider `metadata.openclaw.always: true`; the Skill should load only for relevant journal-advisory requests. ]]>
