vscode-cowriting-plugin

Non-shippable proof-of-concept (Feature #2 of Epic #1): a standalone VS Code extension that drives @cline/sdk — validating Approach A (own coauthoring extension on the Cline SDK, no fork).

What it does

Registers one command, Cowriting: Show Cline SDK Info, which loads @cline/sdk and shows the SDK build version plus the agent's builtin tool catalog (a pure, key-free SDK call) in a notification and the "Cowriting (Cline SDK)" output channel.

Architecture

• CommonJS extension bundled with esbuild (src/extension.ts → out/extension.cjs).
• @cline/sdk is ESM-only (Node ≥22) and uses createRequire(import.meta.url), so it is not bundled — it is shipped in node_modules and loaded at runtime via dynamic import() from the vscode-free src/cline.ts.

Run it (F5)

1. npm install
2. npm run build
3. Press F5 (or Run → "Run Extension") to launch the Extension Development Host.
4. In the new window: Cmd/Ctrl+Shift+P → "Cowriting: Show Cline SDK Info".

Develop

• npm run watch — rebuild on change.
• npm test — run the unit test for the SDK driver.
• npm run typecheck — type-check without emit.
