Track spending changes over time.

You need to know if your CAC is slipping or climbing before you commit to a budget. Use `analyze_mom_trend` to track Month-over-Month shifts for either total spend or the blended CAC itself. This tool doesn't just give you numbers; it tells you whether the trend is worsening (positive number) or improving (negative number). It helps you spot when a channel’s performance starts dipping, so you can adjust before things get bad.

Optimize resource allocation recommendations.

Instead of guessing where to put the next million dollars, let your agent recommend it. `assess_budget_efficiency` takes period data and ranks channels for you. It returns suggested budget percentages alongside natural language advice. This is huge because you get structured JSON output detailing which channels are under- or over-funded relative to their actual CAC performance.

Establish core CAC metrics instantly.

Want a clean, accurate view of your spending? Run `calculate_cac_metrics` by feeding it simple channel spend data. It calculates both the per-channel CAC and the overall blended CAC for any given period. This provides the foundational data set you need—the initial metrics that prove where money is going and what those dollars are actually buying.
