Named entities (e.g., "that song", "the meeting") are looked up in conversation memory. Ambiguous references trigger a user clarification prompt via the `ClientIO` layer. +**Intermediate results** - A translated `resultEntityId` labels a completed +action; it does not require that every successful action manufacture an +entity. The three consumers have distinct contracts: + +- A legacy `${result-id}` parameter consumes `resultEntity.name` and retains + same-agent entity metadata. A missing entity remains an error. +- A `{ "$result": "id" }` parameter consumes only the explicit `resultValue`, + not display text, structured display `rawData`, or an entity name. Before + invoking the consumer, the dispatcher validates the concrete value against + its parameter schema without the translation-time placeholder exemption. + Empty strings, empty arrays, zero, and false are values, not missing results. +- A `pendingRequestAction` remains in the execution queue until its earlier + action completes. Translation receives request-local snapshots of completed + actions and their actual results, including display-only outputs, even when + conversation history or memory extraction is disabled. These outputs are + context for translating the remaining request, not instructions to replay + earlier actions or an automatic switch to reasoning. + + Deferred context uses a projection of result values, entity bindings, history + text, and display data, rather than serializing execution metadata. Identical + value/text representations and duplicate structured `rawData` are omitted; + display alternates and presentation flags are not sent. Distinct display + content is preserved even when history text is only a summary. Entity metadata + continues to be available through the history's entity references. + + The serialized UTF-8 envelope containing the remaining request and its full + history context is limited to 64 KiB. The limit includes all completed outputs, + action parameters, inherited prompt sections, entities, activity state, and + additional instructions. This is a deterministic deferred-context safeguard, + not a token limit for the complete model prompt (which also includes schemas + and other translation instructions). Oversized context stops before translating + or executing the continuation, with an explicit error: no output is silently + truncated or summarized and completed producers are not replayed. Concrete + `$result` substitution is unchanged and does not use this prompt-size limit. + + Deferred translation retains the caller's active-schema and schema-family + restrictions. An unavailable or empty scope stops the continuation rather than + widening it to globally active schemas. Newly translated actions also pass the + execution-eligibility check before entering the queue; unknown or disabled + actions stop the continuation without reasoning fallback or producer replay. + + An unused result label does not turn a successful mutation into a failure. + Errors stop the chain; missing references and invalid concrete values fail + before their consumers execute. Deferred translation cannot use an action + still awaiting confirmation. Continuations retain completed-action history + while each newly translated plan has its own result-reference bindings. + +In legacy action execution, a pending user choice stops the remaining queue, +including actions without result references and any returned additional +actions. The choice remains available, but the dispatcher explicitly reports +that the remaining steps were not executed and will not resume automatically. +This interruption does not trigger reasoning fallback or replay completed +actions. A standalone choice retains its existing behavior. Structured +execution continues to resolve choices through its own awaited interaction +path before returning to the action queue. + Translated actions may also contain **entity placeholders** — explicit references the LLM emits as string values pointing back at entities provided in the prompt's history context. `resolveEntityPlaceholders()` diff --git a/ts/packages/actionSchema/src/validate.ts b/ts/packages/actionSchema/src/validate.ts index 136acc89fe..326822c19a 100644 --- a/ts/packages/actionSchema/src/validate.ts +++ b/ts/packages/actionSchema/src/validate.ts @@ -43,13 +43,14 @@ export function validateSchema( expected: SchemaType, actual: unknown, coerce: boolean = false, // coerce string to the right primitive type + allowResultReferences: boolean = true, ) { if (actual === null) { throw new Error(`${errorName(name)} should not be null`);
