- FeatureFlagService: local JSON config with env override, hot reload, typed accessors
- MetricsCollector: session metrics (tools, commands, tokens, errors), daily JSON persistence
- FeatureGate: connects flags to tool/feature enable checks with status reporting
- Default flags for all major features (server, worktree, LSP, coordinator, etc.)
- Metrics flushed to ~/.claude-code/metrics/{date}.json
