AI Analysis

●●SolidSolve My ProblemNiche GemCozy

PreToolUse hooks block over-budget requests while SQLite tracks Claude Code spend locally.

Strengths
  • PreToolUse hooks block requests when budgets hit instead of just alerting.
  • Local SQLite storage ensures zero telemetry and instant queries without syncing.
  • Efficiency analysis suggests Opus-to-Sonnet routing based on actual session data.
Weaknesses
  • Only supports Claude Code CLI, ignoring API users and other providers.
  • Hook installation modifies Claude config files, creating friction during updates.
