Summary

  • Adds implementing for the Anthropic provider
  • Installs as a gateway dependency
  • Registers claude-opus-4-6, claude-sonnet-4-6, and claude-haiku-4-5 with Pi ModelRegistry
  • Implements via lightweight call
  • Implements with full streaming via , mapping Anthropic events to format
  • Replaces the legacy inline in with the new adapter
  • Gracefully skips registration when is not set (logs warning, does not crash)

Test plan

  • All three quality gates pass: typecheck, lint, format:check (verified locally)
  • Adapter registers with set
  • Adapter skips registration and logs warning without API key
  • returns healthy/degraded/down based on API response
  • streams text_delta, tool_call, and done events
