@anvia/core: Changelog

Release history mirrored from packages/core/CHANGELOG.md.

0.15.0

Minor Changes

• ca24a5e: Emit public tool-call deltas by default for responsive application status, provide an explicit legacy opt-out, propagate the setting through streaming agent tools, and handle append-versus-replace argument snapshots consistently in React clients.

0.14.0

Minor Changes

• d9ac48c: Expose cumulative authoritative usage on failed agent stream events, include provider-reported usage from failed OpenAI Responses requests, and retain failed child-agent usage in built-in observability and Studio traces. Agent error event producers must now provide usage; unavailable provider usage remains empty rather than estimated.

0.13.5

Patch Changes

• 9e190bc: Persist provider, model, and per-generation token usage on generated assistant messages, and show those durable response metrics in Studio’s Memory inspector.
• ede828b: Add optional read-only memory inspection, implement it across the database memory adapters, and let Studio discover persisted agent conversations before falling back to Studio session storage.

0.13.4

Patch Changes

• d196025: Add prompt-scoped completion retries for transient non-streaming and pre-output streaming failures.

0.13.3

Patch Changes

• 8b7fe0d: Reject malformed JSON tool arguments before execution or persistence while preserving valid scalar and blank inputs.

0.13.2

Patch Changes

• b5f285a: Preserve streamed tool call names and provider call IDs when continuation chunks contain empty metadata placeholders.

0.13.1

Patch Changes

• 433f642: Simplify internal optional-property construction while preserving the existing public API and runtime behavior.

0.13.0

Minor Changes

• b52c479: Persist strict JSON message metadata across UI and core message conversions while keeping it out of provider requests and model-generation trace inputs.

0.12.8

Patch Changes

• 26efea0: Match persisted tool results by unique call ID before reused provider IDs and store tool names on new results.

0.12.7

Patch Changes

• b54fba5: Scope live UI tool result matching by turn when reducer events include turn metadata.

0.12.6

Patch Changes

• 70ae42c: Preserve streamed and replayed tool result ordering across text/tool boundaries.

0.12.5

Patch Changes

• 384c8f0: Preserve tool result names when rehydrating persisted UI messages from core messages.

0.12.4

Patch Changes

• 327261f: Preserve streamed assistant content part order when reconstructing final streaming responses.

0.12.3

Patch Changes

• 6cd352e: Fix agent option isolation, deterministic regex eval metrics, and MCP client version metadata.

0.12.2

Patch Changes

• 7b398eb: Add composable React UI primitives for Anvia chat, completion, message parts, and human-input workflows. Merge raw agent tool-call results back into the originating tool part when provider and internal call ids differ. Add UI attachment contracts, chat suggestions, composer attachments, auto-resizing composer input, Markdown rendering, granular tool primitives, thread status helpers, expanded human-input controls, controlled composer state, custom composer submit handlers, optional empty collection mounting, and thinner headless defaults.

0.12.1

Patch Changes

• 2735197: Remove experimental tool and tool-result guardrails. Guardrail policies now cover input and final output boundaries only; use tool approvals, hooks, middleware, and service-level validation for tool execution behavior.

0.12.0

Minor Changes

• eed8b5f: Add experimental guardrail policies for input, tool calls, tool results, and final output.

0.11.3

Patch Changes

• 32171dc: Add provider model-name types for autocomplete while preserving custom string model IDs.

0.11.2

Patch Changes

• 730c23d: Clean up request internals by moving prompt runtime implementation details behind the internal source boundary while preserving the public request API.

0.11.1

Patch Changes

• 9fc55c9: Update upstream runtime dependencies to their latest npm releases.

0.11.0

Minor Changes

• 4068a2a: Send converted core messages from React hooks and keep completion helpers limited to core Message input.

0.10.0

Minor Changes

• 9e4de00: Improve completion stream DX by allowing createCompletionStream() and createCompletion() to accept UI messages directly, and by letting React hooks consume raw completion or agent stream events without a separate UI stream adapter.

0.9.0

Minor Changes

• ca25fca: Add the shared UI message stream protocol for React-facing completions and agents.

  @anvia/core now exposes @anvia/core/ui with UI message types, core/UI message conversion helpers, and adapters for completion and agent streams. @anvia/server adds createUIStreamResponse. @anvia/react now standardizes useChat and useCompletion around UIMessage[] state and the { messages, stream: true } request shape.

0.8.0

Minor Changes

• 3de3cce: Add an optional update? hook on AgentGenerationObserver so observability adapters can record streaming deltas as they arrive.

  The agent loop now awaits observer.update?.({ turn, delta }) for every delta produced by the underlying completion stream. The new method is optional, so existing adapters keep working. A new AgentGenerationUpdateArgs type is exported alongside.

• 3de3cce: Add an optional event? hook on AgentRunObserver so observability adapters can record ad-hoc checkpoints (e.g. retrieval, validation) during a run.

  The new method accepts an AgentRunEventArgs value with a name, optional attributes map, optional level, and optional timestamp. The hook is optional, so existing adapters keep working without modification.

• 3de3cce: Add an optional promptRef?: { name; version? } field on AgentRunStartArgs. Observability adapters can use this to record the prompt name and version on the trace root and on each generation in the run.

  The new field is optional, so existing call sites keep compiling. The AgentRunPromptRef type is also exported alongside.

• 3de3cce: Extend the EvalMetric type with optional Langfuse-related annotations: dataType, scoreConfigId, configId, and metadata. All fields are optional, so existing metric definitions keep compiling unchanged.

  Add a defineMetric() identity helper that wraps a metric definition for clearer intent at call sites. Re-export it from @anvia/core/evals.

0.7.1

Patch Changes

• 2559d04: Refresh upstream runtime dependencies and make pipeline construction schema-first.

0.7.0

Minor Changes

• ef5e727: Add centralized tool approval handling with tool-level approval policies and .approvals(...) decision handlers.

  Add React useChat human-input state for tool approvals and ask_question prompts, including helpers for approving, rejecting, and answering pending human input.

0.6.3

Patch Changes

• 369b6c4: Refactor internal code quality: consolidate duplicate utilities, eliminate conditional spread patterns, and improve file organization.

0.6.2

Patch Changes

• 4806f3e: Add PromptRequest.steer() for enqueueing user messages at safe model-turn boundaries during active prompt runs.

0.6.1

Patch Changes

• 2d039f6: Add ergonomic tool result message helpers and export ToolContent from the root entrypoint.

0.6.0

Minor Changes

• e54aece: Add direct completion helpers for non-streaming, streaming, and parsed structured output flows.

  createCompletion now always returns a final completion result, createCompletionStream exposes raw normalized model stream events, and createParsedCompletion returns schema-validated data from direct completions.

0.5.0

Minor Changes

• 4ab66c9: Broaden agent runtime hooks and add general middleware for completion requests, completion responses, tool inputs, and tool outputs while keeping existing tool middleware APIs as deprecated aliases.

0.4.2

Patch Changes

• 4c1620d: Harden MCP connection cleanup and vector dimension validation, and organize loader internals without changing public loader APIs.

0.4.1

Patch Changes

• 95712d8: Refactor core internals for improved maintainability while preserving public API and behavior.

0.4.0

Minor Changes

• e84d775: Clean up the @anvia/core public import surface by keeping common app-authoring APIs on the root export, moving advanced APIs to focused subpaths, and exposing runtime agent internals through @anvia/core/internal/agent for Anvia integration packages.

0.3.1

Patch Changes

• b12932d: Update upstream dependencies for PDF loading, globbing, Langfuse tracing, and pgvector support.

  The PDF loader now destroys the pdfjs-dist loading task after reading pages, matching the v6 cleanup API.

0.3.0

Minor Changes

• 09c70f5: Add first-class multimodal tool result support.

  Tools can now return ToolResultContent[] directly, or use ToolOutput.content(...), and agent execution will pass structured text/image tool results to model turns instead of JSON-stringifying them. Tool middleware, hooks, observers, stream events, and Studio transcript surfaces keep the existing display string while exposing optional structured result content.

  OpenAI Responses and Anthropic now serialize multimodal tool result images as provider-visible image blocks. Text-only provider fallbacks render image results as media-type placeholders instead of raw base64.

  Update provider and tracing wrapper dependencies to the latest checked upstream releases.

0.2.4

Patch Changes

• a0a5def: Preserve accumulated streamed tool arguments when a provider final response contains an empty tool input.
