Field structure

Field	Type	Required	Description
id	string	Required	Read-only. Check id, reported with the issue and matched against a task's checkIds.
check	(value: Value, context: OperationContext<App>) => CheckResult<Value>	Required	Returns the verdict; unavailable and not-run are not verdicts on the value.

Member index

Member	Purpose
check	Returns the verdict; unavailable and not-run are not verdicts on the value.

AnswerChecker.check(value: Value, context: OperationContext<App>): CheckResult<Value>

Returns the verdict; unavailable and not-run are not verdicts on the value.

Parameter	Type	Passing	Description
value	Value	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: CheckResult<Value>.

Return value structure

Field	Type	Required	Description
status	"unavailable" | "passed" | "failed" | "not-run"	Required	Read-only. See the type definition and usage context.
issues	readonly Issue[]	Required	Read-only. Problems found; expected to be empty when the status is passed.
value	Value | undefined	Optional	Read-only. Checked or produced value; present only when the check yields one.

Examples

• Answering catalog: tasks, source reads, and check references: One task definition ties together the input Schema, reader, output, and check, with real references verified at assembly.
• Answering Flow: item-by-item generation, review, and local repair: Preserve coverage relationships over a split question batch and repair failing items without regenerating the ones that passed.

Register one read task for explanatory material
