docker/docker-agent v1.74.0

on GitHub

This release introduces self-update functionality, session read-only mode, and 1Password CLI integration, along with model selection improvements and various bug fixes.

What's New

• Adds opt-in self-update functionality via DOCKER_AGENT_AUTO_UPDATE environment variable with interactive confirmation
• Adds --session-read-only flag to view sessions without sending messages in TUI mode
• Adds 1Password CLI integration for secret resolution using op:// references
• Adds first_available model selection for automatic fallback across multiple model candidates
• Adds user_steering_messages_submit and user_followup_submit hooks for queued user messages

Improvements

• Updates default agent to use first_available model selection with multi-provider fallbacks
• Updates default model versions: OpenAI from gpt-5-mini to gpt-5, Google from gemini-2.5-flash to gemini-3.5-flash
• Updates coder agent to use first_available model selection instead of hardcoded Anthropic models

Bug Fixes

• Fixes tool call being dropped when finish_reason shares the same chunk in streaming responses
• Fixes orphaned tool results on session resume that caused validation errors on AWS Bedrock
• Fixes agent field not being preserved during command expansion, causing incorrect routing to root agent
• Fixes binary files being processed in content search operations
• Fixes self-update validation to prevent arbitrary file deletion and detect help flags properly
• Fixes IPv6 6to4, NAT64, site-local and CGNAT ranges not being blocked in SSRF protection

Technical Changes

• Hardens self-update download and re-exec process against tampering with digest and checksum verification
• Uses SSRF-safe HTTP client for MCP OAuth metadata fetches
• Hardens 1Password provider against silent pass-through and PATH hijacking
• Fixes custom-base-image evaluation template to include docker-agent binary and entrypoint
• Removes broken MCP servers from configuration
