ReflectionTask.run(question: string, context: OperationContext<App>): Promise<ReflectionReport>

Answers the question from evidence; never throws for incomplete evidence alone.

Parameter	Type	Passing	Description
question	string	Required	—
context	OperationContext<App>	Required	—

Fields of context

Field	Type	Required	Description
app	unknown extends App ? App : Readonly<App>	Required	Read-only. See the type definition and usage context.
logger	SubFlowLog | undefined	Optional	Read-only. Explicit optional recorder for this operation; never inferred from diagnostics.
signal	AbortSignal	Required	Read-only. Non-optional cancellation signal; never undefined once execution has started.
diagnostics	DiagnosticContext | undefined	Optional	Read-only. Diagnostic scope of the enclosing call, when recording is enabled.

Returns: Promise<ReflectionReport>.

Awaited value: ReflectionReport.

Return value structure

Field	Type	Required	Description
id	string	Required	Read-only. See the type definition and usage context.
status	"completed" | "incomplete"	Required	Read-only. incomplete when evidence, model budget or the timeout stopped the work early.
question	string	Required	Read-only. Question as submitted; at most 2000 characters.
findings	readonly ReflectionFinding[]	Required	Read-only. See the type definition and usage context.
limitations	readonly string[]	Required	Read-only. Known limitations, for example exhausted budgets or incomplete coverage.
evidence	readonly ReflectionEvidence[]	Required	Read-only. Evidence items the reflection actually saw.
coverage	readonly { readonly consistency: "best-effort" | "snapshot"; readonly complete: boolean | null; readonly gaps: readonly string[]; }[]	Required	Read-only. Coverage statement of each page that was read.
createdAtMs	number	Required	Read-only. See the type definition and usage context.
expiresAtMs	number | undefined	Optional	Read-only. See the type definition and usage context.
persisted	false	Required	Read-only. Marker: a report is returned to the caller and never stored by the Kit.

Examples

• Log reflection: authorization metadata and evidence reports: The App supplies authorized evidence sources; the reflection task produces a sourced report through ordinary model and tool contracts.

Bind the reflection model, evidence source, and authorization

Beginner · Node.js

TypeScript

import { defineReflection } from '@jangts/agent-core/kits/reflection';
import type { ReflectionSource } from '@jangts/agent-core/kits/reflection';
import type { ModelRunner, OperationContext } from '@jangts/agent-core';

export function review<App>(model: ModelRunner, source: ReflectionSource<App>,
  authorize: (question: string, context: OperationContext<App>) => Promise<void>) {
  return defineReflection({ model, source, authorize,
    maxCalls: 4, reserveCalls: 1, maxPages: 4, maxEvents: 64, maxEvidenceChars: 12000 });
}

JavaScript

import { defineReflection } from '@jangts/agent-core/kits/reflection';
export function review(model, source, authorize) {
    return defineReflection({ model, source, authorize,
        maxCalls: 4, reserveCalls: 1, maxPages: 4, maxEvents: 64, maxEvidenceChars: 12000 });
}

Build the same kind of evidence source from a log reader

Configuration · Node.js

The reader's directory scope, shutdown, and retention are managed by the App. The adapted source can be passed into the same defineReflection.

TypeScript

import { defineReflectionLogSource } from '@jangts/agent-core/kits/reflection';
import type { ReflectionLogReader } from '@jangts/agent-core/kits/reflection';
import type { OperationContext } from '@jangts/agent-core';

export function logSource<App>(reader: ReflectionLogReader, traceId: string,
  authorize: (context: OperationContext<App>) => Promise<void>) {
  return defineReflectionLogSource({ reader, traceId, id: 'authorized-history', authorize });
}

JavaScript

import { defineReflectionLogSource } from '@jangts/agent-core/kits/reflection';
export function logSource(reader, traceId, authorize) {
    return defineReflectionLogSource({ reader, traceId, id: 'authorized-history', authorize });
}
