Major Features

Agent Skills

  • New skills module: Support for the Agent Skills specification — discover skill repositories (SkillsDiscovery), model them as Skill objects, and generate skills-catalog prompts for progressive disclosure and activation. The catalog formatter emits XML, YAML, or JSON. Documented in docs/docs/skills.md (#1383, #2160)

Amazon Bedrock AgentCore Runtime

  • New koog-bedrock-agentcore-runtime module: Run a Koog agent as an Amazon Bedrock AgentCore Runtime entry point, with request/response mapping between the Bedrock Runtime protocol and Koog agents (KG-602, #2154)

Bug Fixes

  • OpenAI Responses API instructions as a plain string: OpenAIResponsesAPIResponse.instructions now accepts both a single value and an array, instead of failing deserialization when OpenAI returns a plain string (KG-898, #2220)
  • Reasoning content in OpenAI streaming deltas: OpenAIStreamDelta now models reasoning_content / reasoning, so reasoning from models like DeepSeek reaches MessagePart.Reasoning and is replayed to the provider on subsequent requests (KG-866, #2190)

Examples

  • Bedrock AgentCore deployment: New example illustrating Koog agent deployment to Amazon Bedrock AgentCore, with tests covering different kinds of content (#2189)
