v0.16.7

Added

• ClaudeAgentOptions#resume_session_at — forwarded as --resume-session-at <message-uuid> to the CLI. When resuming a session, the conversation is truncated to include only messages up to and including the assistant message with the given UUID, enabling history rewriting / branched continuations from a specific turn. Raises ArgumentError from CommandBuilder if set without resume (matches the CLI's own validation but surfaces it synchronously in the caller's stack).
• examples/e2b_transport_example.rb — working ~320-line custom transport that runs the Claude Code CLI inside an E2B Firecracker microVM via the e2b gem. Reuses CommandBuilder for argv parity with SubprocessCLITransport and demonstrates the 6-method Transport interface against a remote backend. README's Custom Transport section now includes an interface table, data-flow diagram, code sketch, and production-hardening checklist that link to the example.

Usage

# Resume a session and rewrite history from a specific assistant turn
ClaudeAgentSDK.query(
  prompt: 'Try a different approach',
  options: ClaudeAgentSDK::ClaudeAgentOptions.new(
    resume: '550e8400-e29b-41d4-a716-446655440000',
    resume_session_at: 'assistant-message-uuid-from-history'
  )
) do |message|
  # only messages up to and including the given UUID are loaded as context
end
