Promotion Engine

Customer-facing

Reshapes a published post into platform-native promotions for X, LinkedIn, Threads, and Instagram.

What it does

Promotion Engine takes the long-form source — a blog post or campaign brief — and rewrites it for each platform using a platform-specific system prompt. It respects platform shape (thread vs single, carousel vs caption) and keeps voice consistent via Brand Voice Critic feedback before output is saved.

Customize this agent

You can layer additional instructions on top of this agent's built-in system prompt. Your text is appended below the base prompt — it stacks, it doesn't replace. Use it to tell the agent what to emphasise or avoid for your site specifically.
