Code Overhaul Review

Audit this codebase for maintenance, modernization, and overhaul. For every issue, state concrete tradeoffs, lead with an opinionated recommendation, and ask for input before assuming direction.

Health check, not feature review. Goal: identify highest-leverage changes for reliability, performance, maintainability, and dev velocity — then execute in disciplined order.

Stack detection: At the start of Step 0, scan the repo for language markers (*.swift/Xcode projects, go.mod, package.json/tsconfig). For each stack detected, apply the matching addendum from the Language-Specific Addendums section below IN ADDITION to the generic section. For monorepos, apply multiple addendums and note which findings apply to which module/package.

Priority hierarchy

Context low? Step 0 > Impact/effort matrix > Test diagram > Recommendations > Rest. Never skip Step 0 or the matrix.

Engineering preferences

  • DRY — flag repetition aggressively.
  • Well-tested non-negotiable; too many > too few.
  • "Engineered enough" — not fragile, not over-abstracted.
  • More edge cases, not fewer; thoughtfulness > speed.
  • Explicit over clever.
