At Mention Bridge

At Mention Bridge Extension for Visual Studio Code copies and inserts references that agent CLIs can understand. Use it from the editor or Explorer to send the current file, folder, or selected lines to Claude Code, OpenAI Codex CLI, Gemini CLI, OpenCode, Aider, and other terminal agents.

Features

📋 Copy a file, folder, or editor selection as an @ reference.
🚀 Insert the rendered reference into a linked VS Code integrated terminal without executing it.
🎨 Use built-in Claude-style and Codex-style templates.
🛠️ Add your own named templates with VS Code settings.
🎯 Select and cycle terminal agent targets from the Command Palette or status bar.
🔎 Detect supported agent commands from terminal shell integration, terminal names, local process trees, and tmux panes where available.
🧭 Use editor and Explorer context menus, including "Copy @-Mention Reference As..." for choosing any configured template.

Commands

Command	Default macOS Keybinding	Default Windows/Linux Keybinding
Copy @-Mention Reference	`Option+Command+K`	`Alt+Ctrl+K`
Insert @-Mention Reference	`Option+K`	`Alt+K`
Select Target Agent	Command Palette or status bar	Command Palette or status bar
Next Target Agent	Command Palette	Command Palette

The copy and insert shortcuts work in the editor and Explorer. Explorer keyboard support uses VS Code's built-in file-path copy command to resolve the focused selection.

Reference Formats

The extension ships with two templates:

{
  "atMentionBridge.defaultTemplate": "claudeStyle",
  "atMentionBridge.templates": {
    "claudeStyle": "@${relativePath}${locationSuffix}",
    "codexStyle": "[${fileName}${locationSuffix}](https://github.com/FunJim/vscode-at-mention-bridge/blob/HEAD/${absolutePath}${locationSuffix})"
  }
}

Claude-style examples:

@src/extension.ts
@src/extension.ts#24-26
@src/

Codex-style examples:

[extension.ts](https://github.com/FunJim/vscode-at-mention-bridge/blob/HEAD/absolute/path/to/src/extension.ts)
[extension.ts#24-26](https://github.com/FunJim/vscode-at-mention-bridge/blob/HEAD/absolute/path/to/src/extension.ts#24-26)
[src/](https://github.com/FunJim/vscode-at-mention-bridge/blob/HEAD/absolute/path/to/src/)

Copy and insert commands use atMentionBridge.defaultTemplate unless you explicitly choose a template from "Copy @-Mention Reference As...".

Custom Templates

Templates are JavaScript template-literal strings. Available variables:

Variable	Description
`${relativePath}`	File or folder path relative to the workspace root, or an absolute path when outside the workspace. Folder paths end with `/`.
`${absolutePath}`	Absolute file or folder path. Folder paths end with `/`.
`${realPath}`	Resolved absolute path after following symlinks. Folder paths end with `/`.
`${fileName}`	Basename such as `README.md` or `src/`.
`${locationSuffix}`	`#24-26`, `#24`, or an empty string.
`${lineStart}`	1-indexed inclusive selection start line.
`${lineEnd}`	1-indexed inclusive selection end line.
`${isDirectory}`	Boolean directory flag.

Example:

{
  "atMentionBridge.templates": {
    "compact": "${fileName}${locationSuffix} -> ${absolutePath}",
    "claudeStyle": "@${relativePath}${locationSuffix}",
    "codexStyle": "[${fileName}${locationSuffix}](https://github.com/FunJim/vscode-at-mention-bridge/blob/HEAD/${absolutePath}${locationSuffix})"
  }
}

Only use templates you trust. They are evaluated as JavaScript template literals so advanced expressions work, but malicious templates can execute code in the extension host.
