docker/docker-agent v1.62.0

on GitHub

This release improves error handling for model context overflow, adds external coding harness support, and includes numerous TUI fixes and performance optimizations.

What's New

• Adds external coding harness agents that delegate coding tasks to external coding CLIs
• Adds support for running context: fork slash commands as sub-sessions instead of inlining them
• Adds docker-agent kit staging in sandbox with skills and prompt files

Improvements

• Classifies overflow errors by kind to provide more specific error messages for different types of context window issues
• Optimizes session browser rendering to only render visible window rows for better performance with large session histories
• Improves shutdown safety by racing Wait() against deadline and calling ReleaseTerminal on timeout
• Updates Gemini adapter to forward stream chunks that carry only UsageMetadata for accurate token counting

Bug Fixes

• Fixes URL clicks in TUI by properly handling mouse events
• Fixes crash prevention by not notifying on click if the agent didn't change
• Fixes deadlock in TUI exit safety net and race conditions in shutdown handling
• Fixes auto-scroll blocking user scroll in long elicitation dialogs
• Fixes MCP tool name prefix stripping in callTool functionality
• Fixes OpenAI strict mode support for Notion and Jira MCP tools with gpt-5
• Fixes user_prompt dialog to open scrolled to top and respect user scrolling
• Fixes keychain prompts in tests by using in-memory token store
• Fixes MCP OAuth handler to drop stray callbacks and respond with proper HTTP status codes

Technical Changes

• Bounds three previously-unbounded caches to prevent memory growth on long sessions
• Uses SSRF-safe HTTP client for remote skills registry
• Honors Cache-Control headers properly in skills caching
• Extracts lrucache package and bounds unbounded caches
• Refactors model override into runAgent request body for atomic model selection
• Updates Grok example to use grok-4.3 model
• Treats wezterm as a terminal that handles shift+enter properly
• Adds clean task to remove generated binary
• Updates various dependencies including Anthropic SDK, AWS Bedrock runtime, and Docker CLI
