Optibot, our senior engineering agent, has expanded its capabilities. Beyond catching functional bugs and security flaws, it now identifies structural issues and maintenance risks specifically targeting the bloat often introduced by AI code assistants.
AI coding tools (like Copilot or Cursor) are fantastic at generating code, but they are often terrible at cleaning up after themselves. They frequently leave behind unused variables, unreachable logic paths, and "zombie" functions that look correct but are never actually called. We call this AI Bloat.
In a recent internal audit, Optibot flagged a getPatternColor function. The function contained a switch statement for pattern types (streak, high_collaboration) that didn't actually exist in the TypeScript definition.

Because the union type for ActivityPattern didn't include these keys, this code was literally impossible to reach—it was just sitting there adding weight to the bundle size and confusing developers.
We know that sometimes "dead code" is there for a reason (e.g., a future feature). That's why Optibot is conversational. You can ask it why a change is necessary.
When Optibot flagged the issue above, we asked it to explain the reasoning. It explained that removing unused code reduces cognitive load and prevents future confusion.
