Package file provides a simple JSONL-backed MemoryStore implementation.

Package opensearch provides an OpenSearch-backed implementation of the MemoryStore interface for persistent, production-grade agent memory storage with BM25 text search and optional kNN vector search via eino's indexer/opensearch and retriever/opensearch components.

Package profilesupervisor provides a profile supervisor agent factory that dynamically selects, at runtime, the sub-agent whose shell sandbox uses the right OCI base image for the task.

Package prune provides a document.Transformer that removes documents whose trimmed content is below a configurable minimum length.

Package opensearch provides an Indexer implementation backed by OpenSearch, plus supporting utilities for index lifecycle management (field mapping merges, source-hash lookups, bulk reconciliation).

Command contextopt_persistent demonstrates how to combine the cross-request session condenser (components/memory/session) with the intra-run context optimizer (components/middleware/contextopt) WITHOUT paying the LLM summarization cost twice.

Package runner bridges an eino adk.Runner run to the cross-request session lifecycle (session.Turn) so that any eino project gets streaming + history persistence out of the box, without re-implementing the glue per project.

Package session provides the generic, cross-request lifecycle for persisting a conversation history on top of a memory.Memory store.

Package agentattr provides an adk.ChatModelAgentMiddleware that attributes the callbacks/activity event stream to a named agent.

Package contextopt provides context-window optimization strategies (inspired by kilocode's session compaction) for the eino ecosystem.

Package promptenhance provides an ADK middleware that enhances user prompts through a small model and optionally asks for human approval before sending the enhanced version to the supervisor.

Package safety provides an adk.ChatModelAgentMiddleware that enforces a safety control layer around LLM tool invocations.

Package cachestab provides a deterministic, non-destructive normalization of tool definitions to maximize prompt-cache stability (port of headroom's tool_def_normalize).

Package chatmodel provides a provider-generic factory for constructing an eino model.ToolCallingChatModel from a single, additive Config.

Package copilot provides a GitHub Copilot provider implementation.

Package github provides eino tools that interact with GitHub repositories, issues, pull requests, releases, branches, and webhooks.

Package opensearch_retriever provides a generic tool.InvokableTool that wraps the existing OpenSearch retriever, enabling semantic document search via natural-language queries as an invokable tool.

Package shell provides an eino shell tool backed by the Dagger engine.

Package websearch provides eino tools for DuckDuckGo web search and URL fetching with anti-bot mitigations (cookie jar, browser headers, session warm-up), HTML-to-Markdown conversion, and SSRF protection.
