}}

  ## ⚠️ 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](/ai-tools/medai-tools-mcp/tools)

  ## 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.

}}
>
  ## 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](/ai-tools/medai-tools-mcp/tools)

  ## 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.

description: "• Echo Agent Kit ships an audio transcription module with Gemini and Eka Care ASR providers, released as v0.1.34\n\nRead more: https://developer.eka.care/ekaagents-changelog"
}}
>
  ## 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](/ai-tools/agent-kit/introduction)

  ## 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](/ai-tools/agent-kit/agents)

  * **\[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](/ai-tools/agent-kit/tools)

  ## 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.

>
  ## 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](/ai-tools/agent-kit/mcp-integration)

  * **\[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](/ai-tools/mcp-server/supported-tools)

  ## 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.
