Prompt Line is a macOS app developed to improve the prompt input experience in the terminal for CLI-based AI coding agents such as Claude Code, Codex CLI, and Gemini CLI.
Prompt Line is a macOS app developed to improve the prompt input experience in the terminal for CLI-based AI coding agents such as Claude Code, Codex CLI, and Gemini CLI.
It provides a comfortable input experience through a floating window.
Key capabilities:
Quick input, quick paste — Floating window with Cmd+Shift+Space, paste anywhere with Cmd+Enter
Context search — Search agent skills, files, symbols, and more with / and @, with prompt history reuse
Extensible via plugins — Add custom search and skills with simple YAML files (Plugin Guide)
Features
Quick Launch, Quick Paste
Quick launch with shortcut (Cmd+Shift+Space).
Type text and quick paste (Cmd+Enter).
Perfect for Editing Voice-Inputted Text
The operation is the same as a typical text editor.
Of course, you can also use it in combination with a voice input app.
Pressing Enter will not automatically send the text, so you don't have to worry about line breaks.
It is also ideal for editing text entered by voice.
(This video uses superwhisper.)
The agent harness performance optimization system. Skills, instincts, memory, security, and research-first development for Claude Code, Codex, Opencode, Cursor and beyond.

Prompt history is saved and can be reused from the right menu.
Search is also available. (Cmd+f)
Launch Anywhere
Can be launched anywhere there's a text input field.
Also convenient when you want to reuse the same prompt in other apps.
Of course, it also works with apps other than Terminal.
Context Search and Autocomplete
Type / or @ to search and autocomplete contexts such as agent skills, built-in commands, files, and symbols.
These can be extended with plugins. See: Plugin Guide | prompt-line-plugins
Xcode Command Line Tools or Xcode (for compiling native tools)
fd and rg (ripgrep) (for file search and symbol search features)
Prompt Line Installation
git clone https://github.com/nkmr-jp/prompt-line.git
cd prompt-line
git checkout v0.x.x # Optional: replace with desired version tag
pnpm install
pnpm run install-app # Build and install to /Applications (includes code signing setup)
Launch Prompt Line. An icon will appear in the system tray.
You can start using it with Cmd+Shift+Space.
Accessibility Permissions
Prompt Line requires accessibility permissions to paste text into other applications.
A dialog box will appear on first use, so follow the instructions to set it up.
Troubleshooting
If the accessibility permissions dialog box does not appear
Open System Settings → Privacy and Security → Accessibility.
Find “Prompt Line” in the list and enable it.
If it is not in the list, add Prompt Line from Applications using the “+” button.
If “Prompt Line” is enabled in Accessibility Permissions but you still cannot paste
Open System Settings → Privacy and Security → Accessibility
Delete “Prompt Line” from Applications using the “-” button to reset permissions
The issue should be resolved after reconfiguring settings.
Accessibility permissions can also be reset using the following command:
pnpm run reset-accessibility
📦 Update
If you already have an older version installed and want to update to the latest version:
git pull
pnpm install
pnpm run install-app
pnpm run migrate-settings # Migrate settings to latest defaults (auto-backup)
Usage
Basic Workflow
Move to where you want to input
Press Cmd+Shift+Space to open Prompt Line

Features
History Panel - Click previous entries to reuse. Search is also available. (Cmd+f)
Draft Autosave - Automatically saves your work

⚙️ Settings
Settings file: ~/.prompt-line/settings.yaml (hot-reloaded, no restart needed)
Plugins are YAML files that add agent skills (/), custom search (@prefix:), and built-in commands/skills/agents for CLI tools.
Quickest way: Place a YAML file in ~/.prompt-line/agent-skills/, ~/.prompt-line/custom-search/, or ~/.prompt-line/agent-built-in/ — no GitHub repo needed.
