Changed

(rig-derive) [breaking] generated #[rig_tool] implementations now target the single Tool::call API with ToolContext and preserve the function's Result<T, E> error as Tool::Error until erased dispatch normalizes it. A tool function may accept one &mut ToolContext parameter in any position; fully qualified rig::tool::ToolContext / rig_core::tool::ToolContext paths are recognized directly, while imported names and aliases use #[rig(context)]. The macro forwards the runtime context and excludes that parameter from the generated arguments and JSON Schema without confusing unrelated application types also named ToolContext.

Changed
(agent) [breaking] Remove the completion-model parameter from
AgentHook, HookStack, and the erased hook interface. Managed response
hooks now receive canonical Rig lifecycle fields (prompt, content,
usage, and message_id) through non-generic CompletionResponse and
StreamResponseFinish events. This lets one concrete hook attach to agents
backed by different providers. Typed raw provider responses remain available
from direct CompletionModel completion and streaming APIs.
// Before
impl<M: CompletionModel> AgentHook<M> for TelemetryHook { /* ... */ }

// After
impl AgentHook for TelemetryHook { /* ... */ }
(agent) [breaking] Remove AgentBuilder::dynamic_context,
ExtractorBuilder::dynamic_context, and the internal DynamicContextStore
passive-retrieval pipeline. Static builder context remains available. Rig no
longer imposes passive-retrieval query selection, retrieval, filtering,
reranking, formatting, caching, failure handling, or per-turn policy; those
decisions belong in an application-defined AgentHook.

Migration example:
// Application code: Rig does not provide AppRetrievalHook.
struct AppRetrievalHook<I> {
    index: I,
    samples: u64,
}

impl<I> AgentHook for AppRetrievalHook<I>
where
    I: VectorStoreIndexDyn,
{
    async fn on_completion_call(
        &self,
        _ctx: &HookContext,
        event: CompletionCallEvent<'_>,
    ) -> CompletionCallAction {
        let message_text = |message: &Message| match message {
            Message::User { content } => content.iter().find_map(|part| match part {
                UserContent::Text(text) => Some(text.text.clone()),
                _ => None,
            }),
            _ => None,
        };
        let Some(query) = message_text(event.prompt)
            .or_else(|| event.history.iter().rev().find_map(message_text))
        else {
            return CompletionCallAction::continue_run();
        };

        let request = VectorSearchRequest::builder()
            .query(query)
            .samples(self.samples)
            .build();
        match self.index.top_n(request).await {
            Ok(results) => {
                let documents = results.into_iter().map(|(_, id, value)| Document {
                    id,
                    text: serde_json::to_string_pretty(&value)
                        .unwrap_or_else(|_| value.to_string()),
                    additional_props: Default::default(),
                });
                CompletionCallAction::patch(
                    RequestPatch::new().extra_context(documents),
                )
            }
            Err(error) => CompletionCallAction::stop(
                format!("application retrieval failed: {error}"),
            ),
        }
    }
}

// Before
let agent = client.agent(model).dynamic_context(3, index).build();

// After
let agent = client
    .agent(model)
    .add_hook(AppRetrievalHook { index, samples: 3 })
    .build();
CompletionCallAction::patch(RequestPatch::new().extra_context(documents))
appends application-retrieved documents after static context. Returning
CompletionCallAction::stop(...) on retrieval failure prevents provider I/O
for that turn. The same hook-aware AgentRunner lifecycle powers blocking,
streaming, and extractor execution; register the local hook with
ExtractorBuilder::add_hook for extraction. Multiple hook context patches
append in registration order. For active RAG, expose an index through its
blanket Tool implementation or provide a custom retriever tool so the model
decides whether and when to retrieve.
(agent) [breaking] Make AgentRunner the only execution path for configured agents: remove the raw Completion and StreamingCompletion traits and their Agent implementations, make agent execution state private, add runner-backed per-request overrides, and route Extractor through the full hook lifecycle. Raw hook-free requests remain available explicitly through CompletionModel.

Migration examples:
// Before: built a one-shot request from configured Agent state, but bypassed
// the AgentRunner lifecycle.
agent.completion(prompt, history).await?.send().await?;

// After, for managed Agent execution: hooks, tools, retrieval, memory, and
// turn accounting all run. Budget enough calls for tool follow-ups.
agent
    .runner(prompt)
    .history(history)
    .max_turns(3)
    .run()
    .await?;
Streaming follows the same boundary:
// Before
agent.stream_completion(prompt, history).await?.stream().await?;

// After
let stream = agent
    .runner(prompt)
    .history(history)
    .max_turns(3)
    .stream()
    .await;
The runner consumes tool calls instead of returning the first raw model
response. If the old caller handled that response itself, or for any other
intentionally hook-free provider transport, start from the model rather than
an Agent:
model
    .completion_request(prompt)
    .messages(history)
    .send()
    .await?;

let stream = model
    .completion_request(prompt)
    .messages(history)
    .stream()
    .await?;
AgentRun::new(prompt).with_history(history) remains the public sans-I/O
state machine for custom drivers. It contains no model, tools, memory, or hook
stack: callers must handle every AgentRunStep, perform provider/tool IO, and
feed results back explicitly. It is not a way to execute a configured
Agent; use AgentRunner for that.

An Agent also keeps its configured model private and fixed. Applications
that previously called .model(...) or .model_opt(...) on the returned raw
request builder should retain the provider CompletionModel and use its raw
request API, or construct a separate Agent for that model selection.
(providers) [breaking] Move Together, OpenRouter, and Mistral embeddings onto the shared GenericEmbeddingModel, with provider-specific endpoint and typed request-shaping hooks. Together now forwards configured embedding dimensions, Mistral maps Codestral Embed dimensions to output_dimension while rejecting dimensions for fixed-size models, compatible providers may omit usage without weakening OpenAI's public response type, and Base64 response encoding is rejected before sending because the shared parser accepts numeric vectors. Remove the superseded provider-specific embedding response/data types, Together's API envelope module, and OpenRouter's duplicate EncodingFormat.

(tool) [breaking] Replace the parallel tool-execution APIs with one structured path. Typed tools now implement only Tool::call(&mut ToolContext, Args) -> Result<Output, Error>; author-facing errors remain typed until private runtime erasure normalizes them into ToolExecutionError, ToolContext carries inbound values and host-only result metadata, ToolResult is the single runtime observation, and ToolSet::execute / ToolServerHandle::execute are the dispatch surfaces. Event-specific hook action types make invalid event/action combinations unrepresentable.

Tool implementations: retain one typed type Error for ordinary ? propagation and direct-call tests; remove classify_error, call_with_extensions, and call_structured. The optional map_error method classifies domain failures at the erased boundary, while its default preserves the source as Other. Return refusals through map_error with ToolExecutionError::refused, and attach host-only result metadata with ToolContext::insert_result.

Context: replace ToolCallExtensions and ToolResultExtensions with ToolContext; replace request/runner .tool_extensions(...) with .tool_context(...). Each dispatch snapshots inbound context exactly once, isolates tool-local mutations, and publishes only result metadata back to the caller and hooks.

Dynamic tools: ToolDyn is removed from the public API; use DynamicTool for runtime-defined tools. Rig's erased dispatch trait is private. Typed tools use Tool::NAME as their sole identity; runtime-named agents convert explicitly with Agent::into_tool().

Registration vocabulary: AgentBuilder::tools(Vec<Box<dyn ToolDyn>>) is removed; use repeated .tool(...) calls for typed tools or dynamic_tools(Vec<DynamicTool>) for runtime-defined callbacks. Retrieval-backed dynamic_tools(sample, index, toolset) becomes retrieved_tools. On ToolSetBuilder, static_tool remains the typed-tool path, the former embedding-backed dynamic_tool(ToolEmbedding) becomes retrieved_tool, and runtime-defined callbacks use dynamic_tool(DynamicTool).

Results and errors: replace ToolError, ToolFailure, ToolFailureKind, ToolReturn, ToolReturnOutcome, ToolExecutionResult, and ToolOutcome with ToolExecutionError, ToolErrorKind, and the read-only ToolResult observed by hooks.

Model presentation: serializable outputs convert once into canonical ToolOutput content blocks; strings remain literal text, explicit serde_json::Value values remain JSON, and multimodal tools use ToolOutput::content / ToolOutput::one or return typed ToolResultContent directly. Result hooks now rewrite ToolOutput, provider adapters preserve native JSON where supported or render it only at their terminal wire boundary, mixed user/tool-result blocks retain order, and Rig never reparses strings to infer rich content. Consumers can inspect ToolResultContent with as_text / as_json and explicitly decode either structured JSON or legacy JSON-bearing text with deserialize_json.

Error presentation: explicit ToolExecutionError constructors keep actionable diagnostics model-visible, while the generic ToolExecutionError::from_error path preserves operator diagnostics and the concrete source but defaults to safe kind-level model feedback. Use with_model_feedback for deliberate replacement text or with_model_output for JSON/multimodal feedback. MCP responses preserve ordered supported text/image content, retain unsupported and future blocks as typed JSON, and attach raw CallToolResult, structuredContent, and response metadata to ToolContext. MCP list installation and refresh are atomic and ownership-aware, so stale handlers cannot replace or remove newer registrations, while disconnected owners are retired during refresh, provider exposure, or direct dispatch.

Dispatch: replace ToolSet::{call, call_with_extensions, call_structured} with ToolSet::execute; replace ToolServerHandle::{call_tool, call_tool_with_extensions, call_tool_structured} with ToolServerHandle::execute.

Registration and definitions: ToolSet is the single ordered registry and records whether each tool is always advertised or retrieval-only. ToolSet::{get_tool_definitions, documents} are now synchronous and infallible, ToolServerHandle registration/removal methods no longer return an artificial Result, and the obsolete ToolSetError is removed.

Hooks: replace AgentHook::on_event, StepEvent, and Flow with the event-specific AgentHook methods and their corresponding action types (CompletionCallAction, ToolCallAction, ToolResultAction, InvalidToolCallAction, and ObservationAction). Result rewrites replace the effective model and result-content telemetry presentation while preserving the raw ToolResult and ToolContext for policy; result stops omit result-content telemetry. Invalid-tool hooks return None to defer; every explicit action, including Fail, is terminal for that hook stack.

Streaming execution observation: the atomically surfaced post-batch event is named ToolExecutionCommitted, reflecting that it is not a real-time start notification. Applications that need live host lifecycle events should observe on_tool_call / on_tool_result; typed result metadata remains available through ToolResultEvent::tool_context without entering model-facing messages.

(core) [breaking] Mark PromptError, StructuredOutputError, and VectorStoreError as non-exhaustive, requiring downstream match expressions to include a wildcard arm. Conversation memory load failures now surface as the typed PromptError::MemoryError variant instead of CompletionError::RequestError.

Added

(neo4j) implement InsertDocuments for Neo4jVectorIndex — bulk-insert documents with precomputed embeddings via a single UNWIND Cypher write (one node per embedding, document fields flattened onto the node alongside embedded_text and the configured embedding property). Nodes are written under the index's label, which get_index now resolves from the index's labelsOrTypes (default Document); IndexConfig gains a node_label field + builder. (closes #1636)
