Thoth for VS Code

Companion extension for the thoth coding agent. Replaces thoth's window-title detection with real editor data:

• active file in the current workspace
• selection (line numbers + selected text, up to 2000 chars)
• diagnostics ("Problems": errors and warnings, up to 50)

How it works

On every editor event (tab switch, selection change, diagnostics update, save — debounced 300ms, plus a 60s heartbeat) the extension writes a small JSON state file to ~/.thoth/ide/vscode-<workspace-hash>.json:

{
  "ide": "VS Code",
  "workspace": "C:\\proj",
  "updated": 1699999999,
  "activeFile": "src/main.rs",
  "selection": { "startLine": 5, "endLine": 10 },
  "selectedText": "...",
  "diagnostics": [
    { "file": "src/lib.rs", "line": 3, "severity": "error", "message": "..." }
  ]
}

Before each request, thoth picks the freshest state whose workspace matches its working directory and injects it as <editor-context> for the model. The file is removed when the extension deactivates; thoth ignores states older than 5 minutes. Everything stays on your machine — nothing is sent anywhere.

Other editors can integrate the same way: write the same JSON shape to ~/.thoth/ide/<editor>-<key>.json.

Build

bun install
bun run build     # -> index.js (CJS bundle, vscode kept external)

Install (local)

Copy package.json + index.js into your VS Code extensions folder:

$dst = "$env:USERPROFILE\.vscode\extensions\thoth.thoth-for-vscode-0.1.0"
New-Item -ItemType Directory -Force $dst | Out-Null
Copy-Item package.json, index.js $dst

Then run Developer: Reload Window in VS Code. No configuration needed.
