opencode-prompt-enhancer

OpenCode TUI plugin that rewrites rough prompt drafts into clearer, stronger prompts.

What it does

• Rewrites rough prompt drafts into clearer, stronger prompts.
• Uses lightweight workspace context.
• Keeps the original intent and language, and does not read file contents.
• Preserves a leading OpenCode slash command while enhancing only its instructions.
• Supports canceling an active enhancement and reverting an unchanged enhanced prompt.

Context used

The enhancer uses:

• the current working directory
• the current VCS branch
• recent user prompts in the current session
• files changed in the current session

Install

For local development without an npm release:

bun run setup

This replaces the released plugin entry in OpenCode's tui.json plugin list with the local checkout. To restore the released plugin entry:

bun run setup:uninstall

The setup command installs dependencies, builds dist, and updates the TUI plugin configuration.

For npm install/publish flows, add the package to OpenCode's tui.json plugin list:

{
  "plugin": [
    "@mtayfur/opencode-prompt-enhancer@latest"
  ]
}

OpenCode >=1.18.12 <2 is required.

Restart OpenCode after changing the plugin configuration.

Model

The enhancer uses OpenCode's small_model when model is not set.

{
  "plugin": [
    [
      "@mtayfur/opencode-prompt-enhancer@latest",
      {
        "model": "anthropic/claude-sonnet-4-6",
        "variant": "high"
      }
    ]
  ]
}

Use

1. Open OpenCode in a workspace.
2. Enter a rough prompt in the TUI prompt.
3. Press Ctrl+E or run the Enhance Prompt command.
4. Review the prefilled dialog, edit it if needed, and confirm.
5. The enhanced prompt replaces the current input.
6. Press Ctrl+Shift+E to cancel an active enhancement or revert to the original prompt. Revert is skipped if the enhanced prompt was edited or is no longer active.
