@ousing9/omo-no-time

OpenCode plugin that removes the Current time: line from the <omo-env> block in system prompts.

Why?

The <omo-env> block injected by oh-my-opencode includes a Current time: line that changes every request. This kills LLM prompt cache hit rates since the system prompt is different each time.

This plugin strips only the time line, keeping date, timezone, and locale intact — so your cache stays stable within a day.

Before:

<omo-env>
  Current date: Thu, Mar 12, 2026
  Current time: 03:42:09 PM
  Timezone: Asia/Shanghai
  Locale: en-US
</omo-env>

After:

<omo-env>
  Current date: Thu, Mar 12, 2026
  Timezone: Asia/Shanghai
  Locale: en-US
</omo-env>

Install

npm install @ousing9/omo-no-time

Then add to your OpenCode config (~/.config/opencode/opencode.jsonc):

{
  "plugin": [
    // ... other plugins
    "@ousing9/omo-no-time"
  ]
}
