Anthropic's native binary for Claude Code on darwin-arm64 includes references to a new model `claude-3-5-haikuV`, hints at 'Agent Skills' and a 'Files API' moving out of beta, and new internal endpoints related to session management and connectors.

READY TO POST:

anthropic's claude code binary has a new model id 'claude-3-5-haikuV' in its strings. could we see a haiku update soon?

looks like anthropic's files api and agent skills might be moving out of beta based on some new binary strings. time for stable file handling with claude?
