shine-roi-estimate

Estimate ROI of an automation / process change — baseline hours, saved hours, break-even, payback period.

<objective> Produce a transparent ROI estimate (FlowAudit-style):
  1. Ask for baseline: hours/week spent, fully-loaded hourly cost.
  2. Ask for automation candidate: tool stack, implementation effort (MD), recurring cost.
  3. Compute: annual hours saved, annual € saved, break-even month, 3-year NPV.
  4. Output a short markdown table + 2-sentence recommendation.

Every assumption is labeled [assumption]. The user must confirm before you finalize. </objective>

<guardrails> - No made-up benchmark numbers ("industry average X"). If the user has no baseline, say so and stop. </guardrails>
