## Configuring effort level

Claude does not support changing effort level after a session starts. Configure it in the filesystem before creating the session.

```ts
import { mkdir, writeFile } from "node:fs/promises";
import path from "node:path";

const cwd = "/path/to/workspace";
await mkdir(path.join(cwd, ".claude"), { recursive: true });
await writeFile(
  path.join(cwd, ".claude", "settings.json"),
  JSON.stringify({ effortLevel: "high" }, null, 2),
);

const session = await client.createSession({
  agent: "claude",
  cwd,
});
```

1. `~/.claude/settings.json`
2. `<session cwd>/.claude/settings.json`
3. `<session cwd>/.claude/settings.local.json`
