Tools

Tool	What it does

`clarify_brief`	Turns a one-line ask into a brief Siren can render
`create_campaign`	Generates the asset. Optional `scheduled_at`, `timezone`, `platforms`
`render_asset`	Renders a specific output type
`list_runs`, `get_run`	Status and result URLs
`post_run`	Publishes a finished run to your connected channels now
`schedule_post`	Queues a finished run for a time in your timezone
`get_brand_dna`, `update_brand_dna`	Read and patch the brand profile

Posts go through the channels already connected in the Siren dashboard: X, LinkedIn, TikTok and YouTube (Instagram once Meta approves the app). The agent never sees your platform tokens.

Example

> Post an update about the new export feature. Use the dashboard screenshot.

The agent calls clarify_brief, then create_campaign, waits on get_run, and calls post_run. One image or film, a caption, and the post, on brand every time.
