Use Tuning to define health rules, signals, procedures, deterministic workflows, and reusable Assistant skills. These settings shape the recommendations and actions Cust produces from your customer data.

Tuning is where all of that configuration lives. Each area has its own page:

AI Health Scoring: define what "healthy", "at risk", and "growth opportunity" mean in your business, in your own words.
Signals: notify CSMs to refresh recommendations when something important happens with a customer.
Guidance: turn a written operating procedure into a structured pipeline with per-customer next-step recommendations.
Workflows: deterministic trigger-condition-action playbooks for the cases you want fully under control.
Skills: reusable AI prompts your whole team can invoke with a slash command.
Email: workspace-wide email behavior, including smart reminder cadence and communication style, the tone and voice the AI uses when it drafts customer-facing content on your behalf.
Knowledge base: product documentation Cust references when answering customer questions or writing replies.
