Variable: E_CONTEXT_RESOLVER_MISSING

const E_CONTEXT_RESOLVER_MISSING: CreatedException<[string, string]>;

Defined in: src/batteries/context/exceptions.ts:54

Thrown when a context-management battery function is called without a REQUIRED injected resolver (estimateTokens, or — for Compact's summarize seam — the model-call function).

Remarks

Both @nhtio/adk/batteries/context/thrift and @nhtio/adk/batteries/context/compact ship with no bundled tokenizer and (for Compact) no bundled model transport — every capability they cannot perform themselves is an INJECTED function the caller must supply. Omitting one is a caller programming error (a wiring mistake, not a runtime condition to recover from): rather than let the omission surface later as a confusing undefined is not a function deep inside the algorithm, every entry point checks eagerly and throws this, naming both the missing option and the function that needed it, so the fix is obvious at the call site. Fatal — construct the missing resolver and retry; there is no degrade-and-continue path, because a battery with no way to measure tokens (or, for Compact, no way to call a model) cannot make progress at all.

Printf args: [functionName, missingOption] — e.g. ['subtractToFit', 'estimateTokens'] or ['summariseTurns', 'summarize'].

Example

import { isInstanceOf } from "@nhtio/adk";

try {
  subtractToFit(ws, contextWindow, relevantToolNames, {} as never);
} catch (err) {
  if (isInstanceOf(err, "E_CONTEXT_RESOLVER_MISSING")) {
    // err.message: "subtractToFit: options.estimateTokens is required — this context-management
    // battery ships with no bundled tokenizer/model transport of its own."
  }
}
