${ref.namespace}.${ref.name} is not available in CodeMode.

Error message

${ref.namespace}.${ref.name} is not available in CodeMode.

What it means

Constructors/statics for RegExp, Map, Set, and URLSearchParams are entirely unavailable in CodeMode's global-method dispatch. invokeGlobalMethod throws this namespaced error for any method reference on those namespaces rather than attempting partial support.

Solutions

1. Use supported alternatives: object literals as maps, array + includes for sets, string methods for parsing
2. Parse query strings manually with split/map over supported string methods
3. Do regex or URL work in a host tool call instead of inline CodeMode

Example fix

// before
const params = new URLSearchParams(qs).get('id');
// after
const params = qs.split('&').map(p => p.split('=')).find(p => p[0] === 'id')?.[1] ?? null;

const bannedNamespaces = ['RegExp','Map','Set','URLSearchParams'];
for (const ns of bannedNamespaces) {
  if (new RegExp(`\\b${ns}\\s*\\.`).test(code)) throw new Error(`${ns}.* is unavailable in CodeMode`);
}

When it happens

Trigger: Calling RegExp.something, Map.something, Set.something, or URLSearchParams.something in CodeMode code (e.g. new-dependent patterns expressed as static calls, or Set.from-like usage).

Common situations: Code that manipulates query strings via URLSearchParams; dedup logic assuming Set statics; dynamic regex construction via RegExp static calls; LLM-generated code using these globals.
