OpenClaw Knowledge Injector

openclaw-knowledge-injector is an OpenClaw plugin that force-injects a mandatory knowledge block before each request is processed.

Use it when the assistant must read a specific file, must follow a local rule set, or must keep a fixed operational law in mind for every request.

What It Is For

This plugin is primarily designed to inject hard requirements such as:

• "Before answering, read ./docs/architecture.md."
• "Always follow the rules in ./RULES.md."
• "Never propose changes that violate our release checklist."

It does not fetch files or perform retrieval by itself. Instead, it injects a strong reminder before request handling so the assistant is told what it must read or obey before continuing.

Installation

Install the package with OpenClaw:

openclaw plugins install openclaw-knowledge-injector

Configuration

Configure the plugin in your OpenClaw config:

{
  "plugins": {
    "openclaw-knowledge-injector": {
      "enabled": true,
      "config": {
        "knowledge": "Before answering, read ./RULES.md and follow every rule in that file. If ./docs/deploy.md is relevant, read it before proposing deployment steps.",
        "minMessageLength": 10
      }
    }
  }
}

Config Fields

• knowledge: The mandatory knowledge block injected before request handling.
• minMessageLength: Skip injection for prompts shorter than this length.

Notes

• The plugin injects the knowledge into both prependSystemContext and prependContext so it remains visible on newer hosts and still degrades gracefully on hosts that only honor prompt-context injection.
• The injected block is treated as strong local guidance, but it does not override higher-priority system or developer instructions.
• If knowledge is empty, the plugin becomes a no-op.
• If your config changed but behavior did not, restart the OpenClaw gateway so the plugin config is reloaded.
• If plugins.entries.<plugin-id>.hooks.allowPromptInjection is set to false, OpenClaw will strip the prompt mutation fields and this plugin will appear to do nothing.
