Summary

  • Convert event-streaming and ai-data-integration from legacy model_tier: reasoning to full model: block with preferred: sonnet
  • Add conditional Opus hold for ai-data-integration when designing novel security tier taxonomies
  • Update model-routing.yaml to v1.4 with Sonnet 4.6 tier mapping and updated cost ratios
  • Update SKILL-MODEL-ROUTING-SPEC.md tier definitions

Part of cross-repo Sonnet 4.6 model routing audit. Estimated savings: ~$7/mo at moderate usage from eliminating Opus invocations in this suite.

Test plan

  • pre-commit run --all-files passes (advisory warning on ai-data-integration token budget is pre-existing)
  • Run event-streaming and ai-data-integration on 2-3 real inputs at Sonnet tier to validate quality
