Generate a title for it'</li> <li>Once the task is completed, Go to '/admin/content/ai-agent-decision'</li> <li>Check the first log. It corresponds to the orchestrator. The system prompt logged is the exact system prompt of the agent.</li> <li>Check the last log. It should be also related to the orchestrator agent. But the logged system prompt is different. Its the system prompt of the previous sub agent that was executed</li> </ul> <h3 id="summary-proposed-resolution">Proposed resolution</h3> <p>In <code>AiAgentEntityWrapper::determineSolvability()</code>, move the <code>$this-&gt;aiProvider-&gt;setChatSystemRole($system_prompt);</code> call immediately before calling <code>$this-&gt;aiProvider-&gt;chat()</code>, so that it always loads the correct system prompt</p> <p>Tested with OpenAI provider, gpt-4.1</p> <h3 id="summary-remaining-tasks">Remaining tasks</h3> <h3 id="summary-ui-changes">User interface changes</h3> <h3 id="summary-api-changes">API changes</h3> <h3 id="summary-data-model-changes">Data model changes</h3>
