Copy Problem Context Agent

Copy compact VS Code problem context for agent prompts, then optionally send it to the active terminal with a configurable instruction suffix.

Features

• Copies the nearest diagnostic within a configurable line window.
• Formats the problem as compact text with severity, language/source, location, and nearby code.
• Sends the copied text to the active terminal for interactive agent CLI workflows.
• Appends a configurable instruction when copying and running in the terminal.
• Uses selected text as the terminal context when running with an active selection.
• Warns for confirmation before copying or running selected text over 5000 characters.
• Runs selected text even when there is no nearby problem, without appending the suffix.
• Keeps terminal execution disabled in untrusted workspaces while still copying to the clipboard.

Copied Format

Copy Problem Context Agent: Copy for Agent copies compact problem context:

Error (source: Pylance): `"(" was not closed`
Location: /Users/example/project/hello.py:5:10

Relevant code:
```python
  2 |     print(f"Hello, World! {i}")
  3 |
  4 | if __name__ == "__main__":
> 5 |     print("Hello, World!"
  6 |
```

Copy Problem Context Agent: Copy and Run in Terminal copies and sends the same context, then appends the configured suffix as a separate paragraph:

Understand the root cause and implement fix.

When text is selected, Copy and Run in Terminal uses that selection instead of the automatic code excerpt. If the selection is longer than 5000 characters, the command asks for confirmation before copying or sending it to the terminal. If no nearby problem exists, it sends only the absolute location and selected text, without the suffix:

Location: /Users/example/project/hello.py:5:5

Selected text:
```python
print("Hello, World!"
```
