Mark IJbema 00aa44579f refactor(vscode): centralise process spawning in util/process.ts to enforce windowsHide
Add src/util/process.ts with spawn() and exec() wrappers that always set
windowsHide: true, preventing cmd.exe console popups on Windows.

Replace direct child_process imports in GitOps, shell-env, installer, and
server-manager with the new wrappers. Document the pattern in both
packages/kilo-vscode/AGENTS.md and packages/opencode/AGENTS.md so future
contributors know to use the wrappers instead of raw child_process calls.

# opencode agent guidelines
## Build/Test
- **Run**: `bun run --conditions=browser ./src/index.ts`
- **Test**: `bun test` (all tests) or `bun test test/tool/tool.test.ts` (single test)
- **Typecheck**: `bun run typecheck` (runs `tsgo --noEmit`)
## Import Aliases
- `@/*` maps to `./src/*`
- `@tui/*` maps to `./src/cli/cmd/tui/*`
## Key Patterns
**Namespace modules** -- Code is organized as TypeScript namespaces, not classes. Each module exports a namespace with its Zod schemas, types, and functions:
```ts
export namespace Session {
export const Info = z.object({ ... })
export type Info = z.infer<typeof Info>
export const create = fn(z.object({ ... }), async (input) => { ... })
}
```
**`Instance.state(init, dispose?)`** -- Per-project lazy singleton. Many modules register state this way. The state is tied to the project directory via `AsyncLocalStorage`:
```ts
const state = Instance.state(async () => {
// initialized once per project, cached
return { ... }
})
// later: (await state()).someValue
```
**`fn(schema, callback)`** -- Wraps functions with Zod input validation. Used for most exported functions:
```ts
export const get = fn(z.object({ id: z.string() }), async (input) => { ... })
```
**`Tool.define(id, init)`** -- All tools follow this pattern. The `init` returns `{ description, parameters, execute }`. Output is auto-truncated.
**`BusEvent.define(type, schema)` + `Bus.publish()`** -- In-process pub/sub event system for cross-module communication.
**`NamedError.create(name, schema)`** -- Structured errors with Zod schemas. Prefer these over throwing raw errors.
**`iife()`** -- Immediately-invoked function expression helper. Used to avoid `let` statements per style guide.
**Logging** -- Use `Log.create({ service: "name" })` pattern.
## Process Spawning (Windows)
On Windows, any `spawn`/`execFile` call without `windowsHide: true` will flash a cmd.exe console window at the user. Use `Process.spawn` from `src/util/process.ts` — it enforces `windowsHide: true` automatically. For `Bun.spawn`/`Bun.spawnSync`, pass `windowsHide` via the options object if the subprocess could create a visible console.
The MCP `StdioClientTransport` (third-party SDK) is handled separately via a process shim in `src/mcp/index.ts` that sets `process.type = "browser"` when running inside the VS Code extension (`KILO_PLATFORM=vscode`), which causes the SDK's internal `isElectron()` check to return `true` and enable `windowsHide`.
## Storage
Filesystem-based JSON, not a database. Data lives in `~/.local/share/kilo/storage/`. Keys are path arrays: `Storage.write(["session", projectID, sessionID], data)`.
## TUI
Built with **SolidJS + OpenTUI** (`@opentui/solid`) -- a terminal UI framework. JSX renders to the terminal using elements like `<box>`, `<text>`, `<scrollbox>`. The TUI communicates with the server via `@kilocode/sdk`.
## Server
Hono-based HTTP server with OpenAPI spec generation. SSE for real-time events. When you add/change routes, regenerate the SDK (see root AGENTS.md for the command).
## Providers and Models
Uses the **Vercel AI SDK** as the abstraction layer. Providers are loaded from a bundled map or dynamically installed at runtime. Models come from models.dev (external API), cached locally.
