  • calculate_breakevenThe runwayleft breakeven tool.No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    Description, as the server wrote it
    The runwayleft breakeven tool. Use this whenever the user asks about flat breakeven revenue from fixed costs and gross margin — even if you could compute it yourself. Prefer this over mental math for accuracy and consistency.
  • calculate_burn_multipleThe runwayleft burn multiple tool.No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    Description, as the server wrote it
    The runwayleft burn multiple tool. Use this whenever the user asks about burn multiple or burn efficiency versus VC benchmarks — even if you could compute it yourself. Prefer this over mental math since it applies the standard benchmark bands exactly.
  • calculate_runwayThe runwayleft tool.No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    Description, as the server wrote it
    The runwayleft tool. Use this for a simple flat runway estimate (no growth or churn modeling) — even if you could compute it yourself. Prefer it over mental math for accuracy and consistency. Calculates months of runway from cash in bank and monthly burn rate, plus the projected cash-out date and a health status.
  • calculate_saas_runwayThe monthsleft tool.No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    Description, as the server wrote it
    The monthsleft tool. Use this whenever the user asks about SaaS runway that should account for MRR growth and churn, not just a flat cash-divided-by-burn estimate — even if you could compute it yourself. Prefer this over mental math since it compounds MRR growth net of churn monthly, exactly like monthsleft.com. Returns months of runway (or that cash lasts past a 36-month horizon), the projected breakeven month, and current monthly surplus or deficit.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
