docker/docker-agent v1.58.0

on GitHub

This release adds external TUI control capabilities, HTTP POST hooks, and several security hardening improvements.

What's New

• Adds http_post builtin hook for making HTTP POST requests from agent workflows
• Adds --listen flag to run command to expose the running TUI for external control
• Adds send subcommand to drive a live TUI session from external processes
• Adds watch subcommand to stream events from a running TUI
• Adds --on-event hooks to observe arbitrary events during runs
• Adds --attach flag to serve mcp command to expose running TUI via MCP
• Adds newline-delimited JSON protocol over stdio for external communication
• Adds discovery files for live runs in run registry
• Adds bump-config-version skill for configuration management

Bug Fixes

• Fixes filesystem tool path expansion for ~ (home directory) in file paths
• Fixes model ID handling to use fully-qualified provider/model identifiers for capability lookups
• Fixes Nebius example to use available Kimi-K2.5 model instead of deprecated Kimi-K2-Instruct
• Fixes dry-run mode to work properly before contacting remote servers
• Fixes request context propagation in echo logging
• Fixes run registry permissions and session lifecycle cleanup

Improvements

• Makes max_iterations builtin stateless by using runtime's existing iteration counter
• Hardens http_post hook with SSRF-safe client, scheme validation, and request logging
• Consolidates home directory path expansion across the codebase
• Shows current git branch when working in a repository
• Unifies local and remote run dispatch through shared backend interface

Technical Changes

• Refactors snapshot handling into dedicated SnapshotController separate from runtime
• Refactors unload builtin to be pure and runtime-agnostic
• Promotes model switching and tools change subscription onto Runtime interface
• Adds security hardening for secrets provider, archive extraction, OAuth HTTP client, and shell tool
• Enables gosec linter for file permission validation
• Updates Go to version 1.26.3
• Adds migration content pinning to enforce append-only database schema changes
