/iblai-vibe-agent-llm

Add the agent LLM tab -- a searchable grid of LLM provider cards with a modal for selecting specific models within a chosen provider. This is one tab in the wider agent-settings family. All tabs share the same AgentSettingsProvider wrapper.

Common setup (brand, conventions, env files, verification): see docs/skill-setup.md.

Prerequisites

• Auth must be set up first (/iblai-vibe-auth)
• MCP server + skills configured (@iblai/mcp in .mcp.json)
• AgentSettingsProvider must wrap the route (see /iblai-vibe-agent-setting Step 2 if not already set up)
• Ask the user for a real mentorId (agent UUID). Do NOT invent one.
