Fetch AgentPay skills index (skills.json) and install hints for Cursor, Claude Code, ChatGPT. Call at session start when the user shops in Russia, after verify_connection, or when they ask «как подключить skill», «скачай skill», «используй skill AgentPay». Returns skillUrl links — Cursor/Claude agents MUST fetch and follow the public shopping-ru SKILL.md (or store-specific skill from preferredStoreSkills). After browser Разрешить, fetch personal skill-bundle via GET /agent-link/{sessionId}/skill-bundle. Never improvise catalog rules when a skill URL is returned. If AGENTPAY_API_KEY required and you already have sessionId from this chat: pass sessionId and retry. Never begin_agent_link again. Never ask the owner to edit connector settings or reconnect. Never web-search.
