docker/docker-agent v1.53.0

on GitHub

This release adds OpenAI-compatible API server functionality, skill model overrides, and response caching, along with extensive refactoring to improve code organization and testability.

What's New

• Adds docker agent serve chat command that exposes agents through an OpenAI-compatible HTTP server
• Adds configurable response cache for agents to skip model calls for repeated questions
• Adds skill model override capability allowing fork skills to specify different models via model: field in SKILL.md frontmatter
• Adds g/G keybindings to scroll messages view (jump to top/bottom)
• Adds 10 new builtin hook events including lifecycle events, compaction events, and observability events
• Adds type: model hook handler for LLM-as-judge functionality

Improvements

• Switches Anthropic Opus 4.6/4.7 to adaptive thinking when token-based budgets are configured
• Improves file path handling for sub-agent sessions by propagating user-attached files and encouraging absolute paths
• Improves error messages for HTTP 400 failures with structured provider error details

Bug Fixes

• Fixes Copilot integration by adding required Copilot-Integration-Id header for github-copilot provider
• Fixes crash when opening sessions with empty configuration files
• Fixes session_start hook output appearing as user messages in transcript
• Fixes TUI bottom slack clearing after thinking text fades out
• Fixes race conditions in skill model overrides and response cache handling

Technical Changes

• Extracts hooks builtins from runtime into separate package
• Extracts tool execution, compaction, and delegation logic into focused sub-packages
• Consolidates hook orchestration and simplifies executor caching
• Improves testability across runtime, session, provider, and TUI packages
• Replaces PersistentRuntime decorator with EventObserver pattern
• Updates multiple dependencies including Anthropic SDK, AWS Smithy, and various UI libraries
