Hotspots

Find and fix the code that's actually causing problems.

Hotspots analyzes your codebase to find functions that are both complex and frequently changed — the 20% of code responsible for 80% of your bugs, incidents, and feature delays.

hotspots analyze src/

# Results show your true priorities:
LRS   File                  Line  Function
12.4  src/api/billing.ts    142   processPlanUpgrade  # Critical — fix this first
9.8   src/auth/session.ts    67   validateSession     # High — watch closely
3.2   src/utils/format.ts    12   formatDate          # Low — safe to ignore

Why Hotspots?

• Objective priorities — Stop arguing about what to refactor. The numbers tell you.
• CI protection — Block new high-complexity functions before they merge.
• Progress tracking — Show stakeholders: "Dropped from 31 critical functions to 23."
