| `selectedTopics` | array of string ≤ 120 chars (max 30) | No |  |
| `accountRules` | string ≤ 500 chars or null | No | The account's writing rules, applied to every draft: short lines such as "No hashtags." At most 500 characters, so keep only the rules that matter most. Replaces the saved rules, so include any existing rules to keep. Null clears them. |
| `account` | string ≤ 64 chars | No | X account to act on, as @handle. Leave it out to use the connection's default account. |
| `dryRun` | boolean | No | Return exactly what would happen without doing it. |
