/**
 * SWML Transfer Skill - Transfer calls between agents using SWML with pattern matching.
 *
 * Port of the Python `SWMLTransferSkill`. Supports the Python `transfers`
 * config (regex-keyed dict of per-destination configs with url/address,
 * message, return_message, post_process, final, from_addr) as well as the
 * TypeScript-native `patterns` array of friendly-named destinations.
 *
 * Either configuration shape works; when both are provided `transfers`
 * takes precedence (matching the Python API).

/**
 * Transfer calls between agents based on pattern matching.
 *
 * Multi-instance capable (distinguished by `tool_name`).
 * Accepts either Python-style `transfers` config (regex → per-entry config)
 * or TypeScript-style `patterns` array of named destinations.
 *
 * @example
 * ```ts
 * agent.addSkill('swml_transfer', {
 *   patterns: [
 *     { name: 'sales', pattern: /sales|pricing|buy/i, to: '+15551112222' },
 *     { name: 'support', pattern: /help|support|broken/i, to: '+15553334444' },
 *   ],
 * });
 * ```
