​
Highlights

  • Agent builder and capability namespaces are reorganized into Cognesy\Addons\AgentBuilder\*, with agent templates in Cognesy\Addons\AgentTemplate\*.
  • Structured extraction is reworked with ExtractionInput, ResponseContent, and streaming-friendly ExtractingBuffer + PartialJsonExtractor.
  • Hub example discovery now supports configurable sources and grouping via YAML config files.

​
Breaking Changes

  • Agent builder, capabilities, and tool registry classes moved from Cognesy\Addons\Agent\* to Cognesy\Addons\AgentBuilder\*.
  • Agent template definitions, registries, and blueprints moved to Cognesy\Addons\AgentTemplate\*; AgentContract is now AgentInterface and fromConfig() returns an AgentInterface (no Result wrapper).
  • Task planning capability (UseTaskPlanning, Todo* classes) and LlmQueryTool were removed.
  • Instructor extraction contracts changed: CanExtractResponse::extract() now accepts ExtractionInput and returns an array, throwing on failure. CanExtractContent, CanParseContent, DataFormat, JsonParser, and ExtractingJsonBuffer were removed.

​
Addons / Agents

  • Agent builder moved to Cognesy\Addons\AgentBuilder\AgentBuilder with capabilities under Cognesy\Addons\AgentBuilder\Capabilities\*.
  • New SubagentProvider/SubagentDefinition contracts and EmptySubagentProvider; AgentTemplate\Registry\AgentRegistry implements SubagentProvider.
  • Agent template registry and definition flow now live under Cognesy\Addons\AgentTemplate\* with explicit blueprint exceptions.

​
Instructor

  • ResponseExtractor now consumes ExtractionInput and uses ResponseContent for tool-mode extraction.
  • Streaming extraction uses ExtractingBuffer and PartialJsonExtractor for more resilient partial JSON handling.

​
Hub

  • Example sources can be configured via config/examples.yaml (multiple source roots supported).
  • Example grouping and ordering can be configured via config/examples-groups.yaml (subgroup include/exclude rules).

​
Migration from v1.21.0

  • Update imports to Cognesy\Addons\AgentBuilder\* (including AgentBuilder, all Capabilities, and Capabilities\Tools).
  • Move agent templates and registries to Cognesy\Addons\AgentTemplate\* and update AgentContract implementations to AgentBuilder\Contracts\AgentInterface with fromConfig() returning an AgentInterface.
  • Remove task planning usage (UseTaskPlanning, Todo*) and LlmQueryTool references; replace with custom tools or direct inference calls.
  • Update custom extractors to CanExtractResponse::extract(ExtractionInput $input): array and throw ExtractionException (or any Throwable); call with ExtractionInput::fromResponse(...) or ExtractionInput::fromContent(...).
  • Replace any direct usage of ExtractingJsonBuffer/JsonParser/DataFormat with ExtractingBuffer and the new extractor chain.
