VS Code is the most popular code editor in the world. It’s excellent for writing code, managing projects, and debugging. But opening VS Code to check a file that an AI agent just modified is like driving to the store for a glass of water when you have a tap at home.

A built-in code editor in your terminal handles the quick inspection workflow without the overhead of switching applications.

Two different jobs

VS Code is for deep editing sessions: writing new features, complex refactoring, debugging with breakpoints, managing extensions, configuring build pipelines.

A terminal-integrated editor is for quick inspection: checking what an AI agent changed, reviewing a config file, making a one-line fix, looking at a file structure.

These are different jobs. Using VS Code for both means you’re alt-tabbing every time you want to glance at a file. That’s context switching you don’t need.

The AI agent review loop

When you’re running AI coding agents, the review loop is the core of your workflow:

Agent completes a task
You review the modified files
You approve, reject, or ask for revisions
Agent moves to the next task

Step 2 is where the editor choice matters. If reviewing a file means:

Alt-tab to VS Code
Wait for it to detect file changes
Navigate to the file
Review
Alt-tab back to terminal

Then each review adds 10-15 seconds of overhead and a full context switch. Across dozens of agent tasks per day, it compounds.

In GridTerm:

Ctrl+click the file path in agent output
File opens in the sidebar editor
Review
Talk to the agent in the same window

Same review, zero switches. The editor is right there.

What GridTerm’s editor does

GridTerm embeds CodeMirror 6 — the same engine used by many web-based IDEs. It provides:

Syntax highlighting — Automatic language detection for TypeScript, JavaScript, Python, Rust, Go, HTML, CSS, JSON, YAML, Markdown, and more
Tabbed interface — Open multiple files, switch between them
Dirty state tracking — Visual indicator when a file has unsaved changes
Line numbers — Navigate by line reference
Basic editing — Make quick changes without switching apps

What it doesn’t do (and shouldn’t)

GridTerm’s editor intentionally doesn’t include:

IntelliSense / autocomplete
Debugging
Git integration (your terminal handles that)
Extensions
Project-wide search and replace
Linting / formatting on save

These features belong in a full IDE. Adding them to a terminal editor would bloat it without adding value for the primary use case: quick file review.

The workflow in practice

Morning setup

Load your GridTerm workspace. Three Claude Code agents start in a 2x3 grid. Dev server launches. You’re ready.

During work

Agent 1 finishes refactoring the user module. Output says:

Modified: src/services/userService.ts
Modified: src/routes/users.ts  
Modified: src/types/user.ts

Ctrl+click src/services/userService.ts → opens in editor tab. Look good. Ctrl+click src/routes/users.ts → new tab. Looks good. Quick glance at types. All correct.

“Looks good, move on to the payment module.”

Total time in editor: 15 seconds. Never left the GridTerm window.

When to switch to VS Code

Complex features you’re writing from scratch. Deep debugging sessions. Large-scale search and replace operations. Configuration of project tooling. These deserve a full editor.

But for the 80% of file interactions that are “look at what changed and verify it’s correct” — the built-in editor is faster and less disruptive.

Not a replacement, a complement

Think of GridTerm’s editor as the “quick look” for code files. You don’t open Photoshop to preview an image — you use Quick Look. You don’t open VS Code to glance at a file — you use the terminal’s editor.

VS Code stays installed. You open it for deep work. GridTerm’s editor handles everything else without the overhead.
