Changed

(rig-derive) [breaking] #[rig_tool] required-ness is derived from the
parameter types so the advertised schema and the deserializer always agree:
without required(...), Option<T> parameters are optional (previously
advertised as required); with required(...), omitted parameters get
#[serde(default)] (their types must be Option<T> or Default). Names in
params(...)/required(...) must match actual parameters, and malformed or
duplicate attribute entries are compile errors instead of silently ignored.
Listing an Option<T> parameter in required(...) is a compile error
(schemars and serde would both silently ignore the directive), and a
wildcard context binding (#[rig(context)] _: &mut ToolContext) is now
rejected — name it _context instead.

(rig-derive) Crate-name resolution and context classification share one
authority: fully qualified &mut ToolContext paths are recognized under
renamed rig/rig-agent dependencies without #[rig(context)], and a
contextual tool without a reachable runtime crate gets a targeted
diagnostic. Generated code resolves serde/serde_json/schemars through
rig-core's re-exports (no direct downstream dependency needed), the
Embed derive emits fully qualified impls (no Embed import needed at the
call site), and parameters() builds its schema once via LazyLock with no
generated expect. A field carrying both #[embed] and
#[embed(embed_with = "...")] is now a compile error instead of being
embedded twice, and a field carrying more than one
#[embed(embed_with = "...")] attribute is a compile error instead of the
first silently winning.

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

Changed

(completion) [breaking] AssistantContent serializes with a "type" tag, exactly like UserContent — the tag is required on deserialize and there is no untagged fallback — 0.41-persisted assistant content (serialized untagged) does not load; insert the tag per MIGRATING's recipe. additional_params on every content block (Text/Image/Audio/Video/Document) is a named serde field instead of a flatten, typed Option<message::AdditionalParams> — a newtype that is a non-empty JSON object by construction (the non_empty_params/params_carry_data helper family is gone; plain is_none()/is_some() are always correct). A stray key can no longer be silently captured and replayed to providers, an absent field round-trips as None instead of the flatten's Some({}) artifact, and a non-object additional_params value is a loud decode error while being unrepresentable in memory. The unknown-key policy is uniform and tolerant across every content block: unknown keys are ignored on load (0.41 flattened extras that were never re-nested load silently minus those keys — verify with message::keys_lost_in_round_trip, per MIGRATING's recipe), and an unknown content-block tag stays a loud error. A 0.41-serialized stream item with flattened text extras decodes as stream text (stray keys dropped, text assembled); a replayed tagged assistant block decodes as StreamedAssistantContent::Unknown and is excluded from assembly — the agent assembler counts those exclusions and logs one warning per turn. A streamed TextStart whose metadata is the empty object no longer opens (or position-fixes) a text block: null and {} are canonicalized to "no metadata" before accumulation, so a {}-only start yields no empty text part and no longer pins part order. The OpenAI Responses wire type responses_api::AssistantContent::OutputText carries its own OutputText wire struct (preserving annotations/siblings verbatim), and on the blocking response path its extras now also survive conversion into generic history under additional_params["openai_responses"], replayed by the Responses serializer alone (the streaming adapter does not yet capture annotation events into params)

(completion) [breaking] pre-provider-split ToolCall JSON is no longer migrated on load: the ToolCallWire legacy lift is deleted, ToolCall deserializes against the current schema only, and a legacy call_id key is ignored as an unknown field — migrate persisted JSON by hand (call_id → provider.call_id, and for dual-identifier payloads also id → the call_… correlator, with the fc_… handle as provider.item_id) if you need those identifiers; see MIGRATING

(tool) [breaking] ToolOutput::as_content returns &[ToolResultContent] instead of &Vec<ToolResultContent>; message::EMPTY_RESPONSE_ERROR (via message::require_non_empty_response) is the one home for the shared empty-response wording every provider decode rejects with. [behavior] Four wires' empty-response error text changes to the shared wording: ollama (was "No content provided"), xai (was "Response contained no output"), vertexai (was ProviderError("No text or tool call content found in response") — the variant changes to ResponseError too), and bedrock's assistant-message conversion (was "Bedrock returned an assistant message with no content")

(completion) [breaking] OneOrMany<T> and EmptyListError are removed; message content, CompletionResponse::choice, CompletionRequest::chat_history, ToolResult::content and EmbeddingsBuilder output are Vec<T>. The serialized form is unchanged (the container already wrote a plain sequence), so persisted histories and stored embeddings need no migration and no recorded fixture changes. Decoding widens in two places that used to be parse errors: [], which the container rejected outright, and null on the fields that moved onto json_utils::string_or_vec (its visit_none/visit_unit arms are load-bearing for OpenAI's tool-calls-only "content": null). A tool with type Output = Vec<ToolResultContent> also compiles unchanged and now takes IntoToolOutput's rich-content path — N ordered blocks instead of one JSON array — because the guard that used to name OneOrMany<ToolResultContent> now names Vec; see MIGRATING. one_or_many::string_or_one_or_many folds into json_utils::string_or_vec; the orphan rule turns three list conversions into the pub free functions openai::completion::{user_content_to_messages, assistant_content_to_messages} and openai::responses_api::reasoning_summaries — see MIGRATING

(completion) [behavior] an assistant turn that carried no text and no tool calls is now empty instead of a fabricated AssistantContent::text(""). Six production sites pushed that part solely to satisfy the non-empty container — including anthropic's documented empty end_turn follow-up — and it reached history and the wire indistinguishable from a real empty text block; is_empty_assistant_turn recognises both spellings of an empty turn — zero parts, or one empty unannotated text block (a shape a blocking wire can still deliver, and the shape old histories encode) — and the agent loop keeps such turns out of history; caller-supplied history is never filtered. Three guards that were unreachable only because of the padding are removed rather than made live: reachable, each would have failed a run that previously succeeded

(completion) the container's two enforcement directions separate: CompletionRequest::validate_message_content rejects an empty chat_history, a content-less user/assistant message, or a tool result whose own block list is empty (named by tool, since ToolResult::content carried the same by-construction guarantee; a single empty-string block still passes — the rule is on block count, not block content) once at the request boundary (called by CompletionRequestBuilder::send/stream, which is also how both agent surfaces issue their requests; System content exempt — it is a String and was never constrained), while inbound per-wire guards route through the new message::require_non_empty(items, || error) — most via require_non_empty_response, which pairs the guard with the shared EMPTY_RESPONSE_ERROR wording (see the dedicated entry); guards rejecting a different state keep their own text; its Option sibling message::non_empty(items) is the one home for the "empty list means absent" rule (the replacement for OneOrMany::from_iter_optional). The OpenAI Responses websocket session validates in send_with_options — it takes a raw CompletionRequest, so it is a direct-to-model surface under the validator's own contract

(tool) [breaking] an empty tool output is rejected at construction: ToolOutput::content is fallible (Vec<ToolResultContent> -> Result<ToolOutput, ToolExecutionError>) and From<Vec<ToolResultContent>> becomes TryFrom — on 0.41 the OneOrMany argument made the empty case unrepresentable, and the Vec argument moves that guarantee into the return type. Every construction route is covered (rich-content tool returns, tools returning ToolOutput directly, hook rewrites), so the failure surfaces as an ordinary tool error fed back to the model instead of a zero-block result entering history and aborting the run at the next request's boundary check. Deliberately not normalized to an empty text block (that would fabricate content the tool never produced); an empty MCP result still normalizes to one empty text block, because that outcome is protocol-legal and outside the tool author's control. text/json/one stay infallible

(ollama) [behavior] converting an assistant history message with empty content no longer mints the legacy vec![AssistantContent::text("")] sentinel — the text block is pushed only when non-empty, matching the response decode path. Consequence: such a converted message cannot be replayed through the request boundary (validate_message_content rejects a content-less assistant message); callers ingesting raw Ollama history filter empty assistant messages rather than rig inventing content for them. The agent loop never produces this shape — it drops empty turns before history

(completion) [breaking] UserContent::tool_result/Message::tool_result record their string as the correlation handle only (echo ToolCall::id), never as a provider-issued id — a bare string cannot prove provider provenance, and stamping an echoed minted handle sent it upstream on optional-id wires as an asymmetric functionCall/functionResponse pair. Wire output on required-id wires is unchanged (the handle is the fallback). Callers holding a wire-issued id use the new tool_result_from_wire (the ToolCall::from_wire mirror), tool_result_with_call_id, or tool_result_for

(streaming) [breaking] RawStreamingChoice::ReasoningEnd gains wire_sent; the driver yields the completed Reasoning block for a payload-carrying end OR a bare end frame the wire itself sent (anthropic content_block_stop on an unsigned thinking block, restoring its pre-lifecycle completed event) — only adapter-synthesized bare ends stay silent. The chat-compat adapter now synthesizes the reasoning end before tool calls as well as text, matching the ollama adapter

(ollama) ToolCall gains id: Option<String>: modern daemons issue "id":"call_..." and rig now preserves it as the durable tool-call id (streaming key + blocking history) instead of discarding it; absent ids still mint. Never serialized back — request shapes are unchanged

(openrouter) id-less encrypted reasoning details key by a dedicated MintKind::EncryptedReasoning, so a whole encrypted block can no longer replace reasoning text accumulating under the shared compat Reasoning mint key

(gemini) [behavior] streamed function calls carry a single-wire identity: the wire's one id travels as the part id only, so provider is {call_id, item_id: None} — filling both slots fabricated a dual identity whose fake item id could pass the foreign-id guard on cross-provider replay, and made stream() and completion() disagree on byte-identical wire content

(cohere) [behavior] an id-less tool call mints its correlation handle and records no provider id, instead of adopting the tool name as a provider-issued id — a name-as-id is fake provenance and collided two parallel same-tool calls in one turn

(xai) [behavior] the request conversion guards its converted input with require_non_empty (id-less reasoning has no xAI representation and drops — now with a warning — so rig-level non-empty content can convert to zero wire items), failing locally with a named error instead of shipping input: [] for a remote 400

(openai) [behavior] a Responses unary response with status: incomplete and an empty choice normalizes with its finish reason (e.g. Length after the documented truncated-function-call drop) instead of being rejected as "contained no message or tool call" — matching the streaming path, which already surfaced truncation this way

(completion) [breaking] tool-call identity is typed: message::ToolCall is { id: ToolCallId, provider: Option<ProviderCallId>, .. } and message::ToolResult is { call: ToolCallId, provider: Option<ProviderCallId>, name: String, .. }. ToolCallId is non-empty by construction and minted at the provider boundary when the wire issued no id (ToolCall::from_wire / from_dual_wire); ProviderCallId carries the wire's call_id plus the dual-wire item id (OpenAI Responses fc_*). Serializers send provider.call_id when the provider issued one, else the minted handle on wires that require an id; optional-id wires (Gemini REST/gRPC) omit minted handles entirely, and the Interactions/Responses/xAI "requires call_id" request errors are gone. ToolResult::name is required and read directly by every name-keyed serializer; the resolve_tool_result_names back-compat pairing shim (and its name-in-id legacy encodings) is deleted. Persisted-history serde is breaking — see MIGRATING

(streaming) [breaking] the raw grammar is a part lifecycle: ReasoningStart/ReasoningEnd/TextEnd join the vocabulary, ReasoningSignature is deleted (a trailing signature is an End arriving late), and the accumulator becomes open-maps into an arrival-ordered part list with entity-owned idempotence — a repeated ToolInputEnd finalizes nothing even with an authoritative payload (review 84a43e9 environment variables? #1), and one end primitive replaces the per-adapter signature/boundary branches (feat(datastore): add Qdrant data store #2). Boundary-less wires synthesize their ends in the adapter; the ordinal machinery, closed_by_full_call, and every adapter-side thought/restatement buffer are deleted

(streaming) [breaking] the raw-event identity is the opaque StreamPartId (no Serialize, no rendering, no durable accessor), with the durable provider handle carried separately as WireId (provider_id on reasoning events, tool_id on RawStreamingToolCall/ToolInputEnd); WireId::new rejects the empty string so absence is None — the fabricated Wire("") class and its per-serializer empty-string filters are gone (review 84a43e9 feat: Add support for Anthropic models #3/feat: Add support for Perplexity models #4). Public delta ids are rig-generated correlators (ReasoningDelta gains provider_id; ToolCallDelta drops id)

(completion) [breaking] message::ToolResult carries the executed tool's name as required data (name: String) — name-requiring wires (Gemini functionResponse.name, Ollama tool messages, Vertex, gemini-grpc) read it directly, and an identifier is never replayed as a name (review 84a43e9 feat: Add support for PostgreSQL vector store #5, pinned by live cross-provider replay cassettes)

(gemini) [behavior] Interactions function-call steps assemble their arguments_delta fragments through the shared accumulator — previously the wire's fragmented tool-call arguments were dropped entirely (the call aggregated with {} args) and an unmodeled arguments_delta frame errored the stream; recorded live in interactions_same_tool_twice

(streaming) [breaking] RawStreamingChoice's part ids (TextStart/ToolCallDelta/Reasoning/ReasoningDelta, ToolInputEnd::id, RawStreamingToolCall::id) are the opaque streaming::StreamPartId; SyntheticIds lives in rig_core::streaming and mints it. ToolCallDelta lost internal_call_id (the shared accumulator mints it at assembly open; read it from StreamedAssistantContent::ToolCallDelta); exhaustive matches over RawStreamingChoice need arms for the lifecycle variants (ToolInputEnd, ReasoningStart/ReasoningEnd, TextEnd) — RawStreamingChoice is not #[non_exhaustive]. MINTED_ID_NAMESPACES/is_boundary_minted_id and the request-side provenance gate are deleted (unrepresentable by construction)

(providers) [breaking] OpenAICompatibleProvider::decorate_streaming_tool_call returns Option<ToolCallDecoration> instead of mutating a &mut HashMap<usize, RawStreamingToolCall>; OutputFunctionCall::arguments is a FunctionCallArguments newtype over the raw string (.parse()/.as_str())

(providers) [breaking] the Anthropic and OpenAI Responses streaming event enums no longer carry #[serde(other)]: unrecognized events triage as Unknown in the classify layer, and a known tag with a defective payload is a decode error instead of a silent absorb

(providers) [behavior] gemini (REST/interactions/gRPC), vertex and ollama no longer fabricate durable tool-call ids — not from an index and not from the tool name, so two calls to the same tool in one turn stay distinct; an id-less call carries a minted ToolCallId with provider: None, replays with the wire id absent on optional-id wires, and the function name a replayed tool result needs travels as the required ToolResult::name

Added

(streaming) wire::classify_typed_event extends the decode-then-validate policy to typed-transport wires (bedrock, candle, gemini-grpc): modeled variants are Known, the SDK's non-exhaustive/unrecognized variants are Unknown, SDK decode errors are Corrupt — a typed transport earns no policy exemption

(streaming) WireAdapter gains an associated Frame type so typed-event wires implement the same contract over their SDK events; classify now takes the frame by value

(streaming) the conformance corpus accepts typed-event input (WireInput::{Bytes, Event}), so typed wires run the shared scenarios events-first with no mock transport; frame-level scenarios a typed wire cannot spell report visible skips

(streaming) wire-sequence conformance corpus (test_utils::streaming_conformance + tests/core) driving raw bytes through each provider's full pipeline; recorded streaming_grammar cassette suites for openai (reasoning summaries, encrypted multi-part reasoning, parallel tool calls, incomplete) and gemini (max-tokens truncation, tool calls, thinking, interactions requires_action)

(streaming) OpenAICompatibleProvider::streaming_detail_reasoning — a defaulted hook letting an OpenAI-compatible provider map a per-chunk streaming detail onto a complete reasoning block instead of a tool-call decoration

(completion) ToolCall::wire_call_id()/ToolResult::wire_call_id() — the one derivation for a required-id wire's call-id slot (provider-issued when it exists, else the minted handle), replacing the expression every serializer hand-rolled — and ToolCallId::for_provider, the shared correlation-handle derivation

(completion) add typed raw_completion/raw_stream escape hatches on every provider model

(completion) add public ProviderCapabilities, replacing CompletionModel::composes_native_output_with_tools

Fixed

(anthropic) a streamed turn's Usage::input_tokens prefers the terminal message_delta and falls back to message_start, instead of always reading message_start. Anthropic proper reports the count on both frames and they agree, so nothing changes there; Anthropic-compatible gateways need not, and OpenRouter's Messages endpoint can send input_tokens: 0 on message_start with the real count on message_delta (observed when it routes to an Amazon Bedrock upstream) — which silently surfaced as Usage { input_tokens: 0 }, worse than a missing value for a consumer sizing a context window from it. A zero on the delta is read as "not reported" so a gateway with the inverse split cannot erase a count message_start got right

(providers) name-keyed wires (Gemini REST/Interactions, Ollama, Vertex AI, gemini-grpc) fill a cross-provider ingested result's empty name from its paired call at request assembly (providers::internal::resolve_empty_tool_result_names, matched by identifier only) — rig's own inbound converters stamp "" because the Anthropic/OpenAI-chat/Cohere/Bedrock wires carry no name, and replaying it raw was INVALID_ARGUMENT

(openai) a Responses tool call whose output_item.done frame was lost survives a healthy response.completed: the terminal closes every open slot (with the announced dual-wire identity) and the call finalizes from its streamed fragments instead of being discarded as truncation — the same terminal-proof drain Interactions and chat-compat ship

(gemini) an Interactions streamed call carries a single-wire identity: its fc_* id lands in provider.call_id with item_id empty, instead of a fabricated Responses-shaped dual id whose fake item id passed the foreign-id guard on cross-provider replay

(streaming) whole-call adoption accepts the two gateway shapes it rejected: a nameless args-only assembly (empty name is no evidence against the restatement) and a buffer still holding the literal null placeholder (covered vacuously) — both used to publish the call under a fresh minted id and finalize the assembly as a duplicate

(openai) a multi-block Responses reasoning done item (summaries + encrypted_content) aggregates as ONE part: the adapter emits one wire-sent end restatement carrying every block in wire order, so history replays exactly one rs_* input item instead of same-id siblings that duplicated the reasoning input on the next request (xai shares the fix)

(openai) Responses reasoning keys are slot-scoped like the tool path: a slot mixing id-bearing and id-less frames (gateways, ChatGPT envelope-less replays) keeps one assembly key fixed at the slot's first event, and the done item resolves through the slot map — no more orphaned partial part beside the superseded one

(openai) an unparseable restated done-item argument string is re-emitted into the assembly buffer only when no function_call_arguments.delta fragment preceded it — fragments already streamed those bytes, and the re-emit doubled them against consumers and the accumulation bound

(streaming) a second signature under a per-stream constant reasoning key (gemini, cohere, ollama) records a distinct signed part instead of overwriting the first — signatures cannot merge, and the overwrite left only the last one to replay (`MISSI
