Conflicts & caveats

• OpenCode is a terminal-first CLI; running it inside Replit works but the experience is in the embedded terminal.
• Replit has its own built-in AI Agent — external integrations like OpenCode cannot run inside the Replit web IDE.
• OpenCode does not officially support Xcode. Use GitHub Copilot for Xcode or Direct API.
• OpenCode has limited or no official Android Studio support. Use GitHub Copilot or JetBrains AI Assistant.
• Void Editor is BYO-API-key first — OpenCode runs as an extension on top, which can work but isn't the intended Void workflow.
• Lapce has a small plugin ecosystem; OpenCode may not have an official plugin yet.
• Positron is VS Code-based but tuned for R/Python data science — OpenCode may install but is not officially supported.
• OpenCode does not officially support RStudio — use direct API calls or the rstudio.cloud Copilot integration.
• OpenCode does not officially support Spyder — use the direct API.
• Cursor Mobile only runs Cursor-managed agents and background tasks — local-only integrations like OpenCode cannot run on the phone.
• OpenCode does not officially support Eclipse — Copilot, Tabnine, and Codeium are the main supported options.
• OpenCode does not officially support Apache NetBeans — Copilot and Tabnine are the main supported options.
• @codebase (Cursor) only works with Cursor built-in integration (yours is OpenCode).
• Continue's codebase indexing only works when the integration is Continue.dev (yours is OpenCode).
• Windsurf codebase indexing only works with Windsurf Cascade integration (yours is OpenCode).
• Aider architect mode requires the Aider integration (yours is OpenCode).
