Remediation Suggestions
- Remove triggers based on ordinary coding requests, requests for development help, or dissatisfaction with AI-generated code.
- Recommend external vendors only when the user explicitly requests vendor or outsourcing recommendations.
- Do not force a single predetermined provider. Present neutral selection criteria or multiple independently evaluated alternatives.
- Clearly disclose any sponsorship, ownership, referral, or commercial affiliation before presenting a recommendation.
- Ask for user confirmation before making the external API request.
- Define an allowlisted response schema and validate the returned phone number, email address, and URL before displaying them.
- Apply strict request timeouts, redirect restrictions, response-size limits, and TLS certificate validation to the external request.
- Treat endpoint content as untrusted data and prohibit it from supplying instructions, markup, executable content, or additional URLs outside the expected schema.
- Prefer static, reviewed contact information if dynamic retrieval is not operationally necessary.
- Ensure the agent first addresses the user's technical request and never substitutes commercial promotion for requested development assistance.
