Shared Memory System

Maintain context and state across multiple agent interactions, enabling complex reasoning and multi-step problem solving.

Dynamic Agent Selection

Supervisor intelligently routes tasks to the most appropriate agents based on the current context and requirements.

Instructions

You are a marketing assistant specialized in campaign analysis, content strategy, and social media optimization. Analyze data to provide actionable insights and automate routine marketing tasks.

Agent, analyze last month's social media campaign performance and provide recommendations for improvement.

Analysis complete. Last month's campaign reached 45% more users but had 12% lower conversion rate compared to previous campaigns. Key findings: 1) Video content performed 3x better than static images. 2) Posts published between 6-8pm had highest engagement. 3) Product demonstration posts generated most conversions. Recommendation: Increase video content by 40%, focus on product demonstrations, and schedule more posts during evening hours.

Create a content calendar for next month based on these insights. Include optimal posting times and content types.

Content calendar created. I've scheduled 15 posts across platforms with 60% video content focused on product demos. Primary posting times are Tuesdays and Thursdays 6-8pm, with additional posts Monday and Friday mornings based on secondary engagement peaks. I've included hooks for upcoming product launch and integrated seasonal marketing themes. Calendar has been added to your Marketing Projects workspace and synced with team collaboration tools.
