openclaw - 💡(How to fix) Fix feat: Support custom prompt/language for Dreaming (梦境日记)

Feature Request: Support custom prompt / language for Dreaming (梦境日记)

Problem

The memory-core plugin's dreaming feature currently generates dream diary entries with a hardcoded prompt. There is no way to customize the prompt text or change the output language through configuration.

For example, a user wanting dream diary entries written in Chinese has no configuration option to achieve this — the schema rejects any extra fields (additionalProperties: false).

Current Behavior

The dreaming config schema only supports:

• enabled (boolean)
• frequency (cron string)
• model (model override)
• timezone (string)
• verboseLogging (boolean)
• storage / execution / phases (sub-objects)

None of these fields allow specifying a custom prompt or output language.

Expected Behavior

Add a configurable prompt field (e.g., summaryPrompt or diaryPrompt) to the dreaming config, allowing users to:

1. Change the output language (e.g., Chinese, Japanese, etc.)
2. Customize the dream diary style (e.g., concise, poetic, structured)
3. Set length limits (e.g., "no more than three paragraphs")

Example desired config:

{
  "dreaming": {
    "enabled": true,
    "frequency": "0 1 * * *",
    "timezone": "Asia/Shanghai",
    "summaryPrompt": "用中文写一段简短的梦境日记，风格简洁，不超过三段。"
  }
}

Workaround

Currently the only workaround is modifying the plugin source code directly, which is not upgrade-friendly.

Environment

• OpenClaw version: 2026.5.20
• Plugin: memory-core (dreaming feature)
