Cursor

Build me an AI coding setup to replace Cursor, assembled from parts I own. Requirements: - Do not write an editor or an agent. Install and wire together: VS Code or VSCodium, the Continue extension for in-editor chat, edit, and autocomplete, and a terminal agent (aider or Claude Code) for multi-file jobs. - Continue config at ~/.continue/config.yaml: chat and edit on Claude Sonnet, autocomplete on a cheap fast model (Codestral, or qwen2.5-coder via Ollama to keep completions local and free). - All API keys read from environment variables set in my shell profile, nothing hardcoded in any config file. - Enable Continue's codebase indexing on my main repo and verify a where-is-this-defined question retrieves the right file. - Keybindings mapped to muscle memory: cmd+K edit selection, cmd+L chat, Tab accepts completions. - A spend check in the README: per-token API pricing vs the $20 flat fee, and a reminder to compare the provider dashboards after two weeks of real use. - Out of scope: cloud and background agents, Cursor's composer UX, and team features; that iteration speed is exactly what the subscription buys. - README: install commands per OS, the full config file, and how to swap models later.
