EkaAgents Changelog

​

⚠️ Breaking

• [EkaAgents] echo-sdk prompt-schema rename — AgentConfig, PersonaConfig, and TaskConfig are renamed to AgentPrompt, PromptPersona, and PromptTask and have moved from echo.agents.config to echo.prompts.schemas. GenericAgent and AgUiAgent now require agent_prompt= instead of agent_config=, FetchedPrompt.agent_config is now FetchedPrompt.agent_prompt, and load_agent_config() is replaced by load_agent_prompt(). The old module path and kwargs are removed — callers must update imports and constructor arguments before upgrading to 0.3.3.
• [EkaAgents] echo-sdk skill package move — echo.agents.skill.Skill is now echo.skills.Skill; Skill is no longer re-exported from echo.agents. Update imports to from echo.skills import Skill.

​

Added

• [EkaAgents] Runtime skill configuration in echo-sdk — New echo.skills.SkillRuntimeConfig (name, description, prompt_config: PromptConfig, tool_names) plus a build_skills_from_runtime() helper that fetches every skill’s prompt in parallel via the configured prompt provider and materialises them into Skill instances. Individual prompt-fetch failures are logged and the offending skill is dropped, so one bad skill config no longer breaks the whole turn.
• [EkaAgents] PromptConfig descriptor — New Pydantic model for fetching prompts from a provider (currently langfuse), with name, version, and prompt_variables and automatic whitespace-stripping on name. Used by SkillRuntimeConfig and intended for host apps that wire skill prompts dynamically.

​

Changed

• [EkaAgents] Langfuse prompt provider returns AgentPrompt — LangfusePromptProvider.get_prompt() and FetchedPrompt now expose agent_prompt (was agent_config); the underlying Langfuse-side schema (role, goal, backstory, expected_output on the prompt config; description in the prompt text) is unchanged.

​

Added

• [EkaAgents] show_appointments_basic and get_patient_appointments_basic in Eka MCP SDK — eka-mcp-sdk v0.1.40 enables show_appointments_basic (list appointments with filters) and v0.1.41 adds get_patient_appointments_basic (fetch appointments for a specific patient), giving agents direct read access to the appointments surface without bespoke tool wiring. View docs

​

Changed

• [EkaAgents] show_appointments_basic patient_id filter constraint — show_appointments_basic in eka-mcp-sdk now treats patient_id as a single-value filter — when a patient id is supplied, other filters are ignored — making the contract explicit and reducing ambiguous query combinations.

​

Added

• [EkaAgents] CRM lead-creation tool in Eka MCP SDK — eka-mcp-sdk ships a new MCP tool for creating CRM leads, letting agents capture and route a lead in the same conversation flow as discovery and booking.
• [EkaAgents] AG-UI streaming in Echo Agent Kit — echo-sdk adds AG-UI streaming support so agents can emit incremental UI updates to compatible clients during a turn instead of buffering the full response.
• [EkaAgents] Claude prompts in Echo Agent Kit — echo-sdk adds prompt support for Anthropic Claude models, broadening the LLM provider mix available to agents built on the kit.

​

Added

• [EkaAgents] Agent skills in Echo Agent Kit — echo-sdk introduces a skills concept for building modular, reusable agent capabilities that can be composed into larger workflows.

​

Improved

• [EkaAgents] doctor_availability success response in Eka MCP SDK — eka-mcp-sdk enriches the success response from the doctor availability flow so downstream booking tools have the context they need without re-querying.

​

Improved

• [EkaAgents] Selected hospital pushed to the top in Eka MCP SDK — eka-mcp-sdk now surfaces the user’s selected hospital at the top of availability listings, so chosen-hospital options aren’t buried under nearby alternatives during a booking flow.

​

Added

• [EkaAgents] service_availability_elicitation and book_service in Eka MCP SDK — The Eka MCP SDK gains two new tools for service and health-package booking flows: service_availability_elicitation (interactive UI tool that lets users discover services, view available dates, and pick a slot — accepts either suggested_service_ids or a single service_id, plus optional hospital_id, preferred_date, and preferred_slot_time) and book_service (creates a health-package booking from a ServiceBookingRequest with deduplication of concurrent calls and slot-unavailable handling). The shared elicitation builder was also generalised with an entity_type parameter so the same UI contract powers both doctor and service flows. View docs

​

Improved

• [EkaAgents] doctor_availability_elicitation now returns selected_doctor_id and selected_hospital_id — When the elicitation completes successfully, the tool result now includes selected_doctor_id and selected_hospital_id in _meta.tool_result, so downstream booking tools can chain off the elicitation output without re-prompting the user.

​

Improved

• [EkaAgents] doctor_availability_elicitation aligned with search_doctor_tool — The Eka MCP SDK removes the legacy doctor_discovery tool references and updates doctor_availability_elicitation to consume results from search_doctor_tool. The tool description and UI contract were updated to render multiple doctor cards in a single elicitation, and suggested_doctor_ids is now an accepted input parameter so an agent can hand a shortlist directly to the elicitation. View docs

​

Added

• [EkaAgents] Audio transcription module in Echo Agent Kit — Echo Agent Kit adds a new echo.audio module with a BaseTranscriber interface, a TranscriberConfig model, and two pluggable providers: GeminiTranscriber (Gemini 2.0 / 2.5 audio models) and EkaCareTranscriber (Eka Care ASR over HTTPS, supporting en-IN, en-US, and hi). Audio can be supplied as raw bytes (with explicit mime_type), a public URL, or a Gemini Files API URI. A new echo[ekacare] extra pulls in httpx for the Eka Care provider. get_transcriber(config) and generate_transcriber_config(...) factory helpers make it straightforward to swap providers without rewriting agent code. View docs

​

Improved

• [EkaAgents] Echo Agent Kit v0.1.34 — Echo Agent Kit released as v0.1.34 with the new audio transcription module bundled in. The Gemini install hint was also corrected from google-generativeai to google-genai. pip install -U echo is safe — defaults preserve existing agent behavior.

​

Added

• [EkaAgents] Skills in Echo Agent Kit — GenericAgent now supports Skill — a lazy-loaded bundle of (instructions + tools + description) that can be attached and detached mid-conversation. Two activation modes are supported: llm (default, agent auto-injects load_skill / unload_skill meta-tools and an <available_skills> registry into the system prompt so the model self-routes between flows) and manual (host calls await agent.activate_skill(name) from an upstream router). Skills also expose on_activate / on_deactivate lifecycle hooks for tenant-scoped setup or telemetry. Tool-name collisions across base tools and skills are caught at agent construction. Existing agents that don’t pass skills= are byte-for-byte unaffected. View docs
• [EkaAgents] Postgres engine and PgQueryTool in Echo Agent Kit — Echo Agent Kit now ships an opt-in Postgres client (echo[postgres] extra) backed by an asyncpg connection pool with lazy initialization, plus PgQueryTool — a BaseTool subclass that runs a parametric SQL query and returns rows. SQL files can use psycopg-style %(name)s placeholders, which the client rewrites to asyncpg $N positional binds. A process-wide default client can be registered with set_default_client(...) so dynamic loaders that call tool_class() resolve correctly. Configuration is read from ECHO_PG_* environment variables. View docs

​

Improved

• [EkaAgents] Echo Agent Kit v0.1.33 — Echo Agent Kit released as v0.1.33 with the new Skills primitive, Postgres engine, and PgQueryTool bundled in. pip install -U echo is safe — defaults preserve existing agent behavior.

​

Improved

• [EkaAgents] MedAssist web file upload validation — The MedAssist web widget now validates uploaded files against an updated allow-list of supported file types, surfacing a clear rejection for unsupported formats before the upload is attempted.

​

Fixed

• [EkaAgents] [Client-Specific] MedAssist web widget configuration — Resolved a configuration regression that caused the MedAssist web widget to behave incorrectly on a partner deployment; the widget now initializes with the expected configuration on that surface.

​

Changed

• [EkaAgents] Mobile number mandatory for profile creation in MCP SDK — The MCP SDK now requires a mobile number when creating a patient profile, ensuring downstream integrations always have a contactable identifier. Existing profile creation flows must include this field. View docs

​

Improved

• [EkaAgents] [Client-Specific] Doctor card revamp — Doctor discovery cards in the MCP SDK have been redesigned for the EMR client, with refreshed layout and additional doctor metadata surfaced inline. View docs

​

Added

• [EkaAgents] MCP session caching in Echo Agent Kit — The Echo Agent Kit MCP integration now caches MCP sessions per user, splitting tool discovery and session caches with independent idle and absolute TTLs, LRU eviction on pool exhaustion, and user_session_id plumbed through MCPTool.run via tool_context. Tool cache keys are partitioned by configurable headers (tool_cache_key_headers), and concurrent cache misses are serialized to avoid duplicate discovery work. View docs
• [EkaAgents] Doctor discovery elicitation — The MCP SDK now supports interactive elicitation for doctor_discovery cards, allowing agents to confirm doctor availability mid-conversation before booking. View docs

​

Improved

• [EkaAgents] MCP tool call timeout — Tool calls in the Echo Agent Kit MCP integration are now bounded by a 10-second timeout, preventing slow downstream tools from blocking agent responses indefinitely.

​

Removed

• [EkaAgents] Legacy MCP caching layer — The previous monolithic MCP cache has been removed from the Echo Agent Kit in favor of the new split tool/session caching design.

​

Fixed

• [EkaAgents] MedAssist web microphone restored — A temporary disablement of the microphone capture path in the MedAssist web widget was reverted on the same day after a regression was identified, restoring voice input.

​

Added

• [EkaAgents] Contextual popup in MedAssist web widget — The MedAssist web chat widget now supports a contextual popup, surfacing relevant suggestions and actions tied to the current conversation state.

​

Improved

• [EkaAgents] MedAssist nudge configurability — The onboarding nudge in the MedAssist web widget can now be disabled by integration partners that don’t want unsolicited prompts on first load.

​

Fixed

• [EkaAgents] Agent ID resolution in MedAssist web — Fixed a bug where the MedAssist web widget could resolve to the wrong agent ID under certain configurations, ensuring conversations always route to the configured agent.

​

Improved

• [EkaAgents] Doctor discovery tool in MCP SDK — The Eka MCP SDK now includes a doctor discovery tool for EMR workspaces, enabling agents to search for available doctors within a clinic context. View docs
• [EkaAgents] MedAssist web widget responsive layout — The MedAssist web chat widget now renders correctly on small screens (under 360px and 767px widths), preventing layout overflow and improving usability on mobile devices.

​

Added

• [EkaAgents] OTP authentication for EMR clients in MCP SDK — The Eka MCP SDK now includes an authentication_elicitation tool enabled by default for EMR workspaces, supporting SMS-based OTP login with country code selection, OTP verification, and UHID profile selection. Agents can authenticate clinic users mid-conversation without leaving the AI client. View docs

​

Improved

• [EkaAgents] MCP SDK workspace tool fallback — When a workspace has no explicitly configured tool list, the MCP SDK now falls back to the default EMR tool set instead of failing, improving resilience for new workspace onboarding.

​

Improved

• Echo Agent Kit — Empty prompt variables are now handled gracefully, preventing errors when prompt templates contain optional or unfilled placeholders. View docs
