2. Requirements
Before installing, check the list below. Required items are the minimum for Aefos to work; optional ones enable extra features.
Required
| Item | Requirement | Note |
|---|---|---|
| IDE | RAD Studio Delphi 13 (BDS 37.0) | Minimum and only supported version |
| OS | Windows | The plugin is Windows-only |
| AI CLI | At least one of: Claude Code, Codex, GitHub Copilot CLI, or Gemini | "Bring your own" — no CLI is bundled. See AI providers |
Without an installed and logged-in AI CLI, the Chat opens normally, but sending messages "does nothing" — there is nowhere to dispatch the prompt.
Recommended
| Item | For what | Where to get it |
|---|---|---|
| WebView2 Runtime | Rich rendering (Markdown + syntax highlighting) in the Chat | https://aka.ms/webview2 |
Without WebView2 the Chat still works, but falls back to plain text (no formatted Markdown).
Optional
| Item | For what | Where to get it |
|---|---|---|
Python (py / python) |
Run PyTools (Python MCP tools you drop into a folder) | https://python.org or winget install Python.Python.3.12 |
PowerShell 7+ (pwsh) |
Helper scripts (build/installer) | Bundled with Windows (older version); 7+ optional |
What you do not need to install
- SQLite — already statically embedded in the plugin; there is no
sqlite3.dllto install. - Delphi runtimes (RTL/VCL/FireDAC) — already part of your RAD Studio.
