Designing Terminal UX for AI is really about DX (and a few classic UX principles)

A lot of AI devtools talk about models. However, another hard problem is DX ("Developer Experience"): how do you make an AI assistant feel native inside the terminal, without breaking the muscle memory developers already have?

When we built Aye Chat, the UX playbook looked surprisingly “traditional”:

1) Hierarchy first: route user intent the way a shell does

In a terminal, ambiguity is the enemy. So Aye Chat treats input with a clear priority:

• Built-in commands (help / restore / model / etc.)
• Shell commands (run the real command directly)
• Everything else becomes an AI prompt

This is a classic hierarchical decision tree: predictable, fast, and easy to learn. The key DX benefit is you don’t “leave the terminal mindset” to use AI.

2) Progressive disclosure: power features only appear when you need them

The terminal is already dense; AI shouldn’t add UI clutter.

Aye Chat keeps the default experience minimal (type a prompt, get an answer), then progressively reveals capabilities:

• help exists, but it’s not forced into every interaction.
• verbose on|off toggles how much operational detail you see.
• RAG context selection is usually invisible; in verbose mode you can see which files were included.
• For large projects, indexing runs in the background; you only see progress if you opt into verbosity (and it shows as a small inline hint in the prompt).

This keeps the “happy path” clean while still supporting the power-user path.

3) “Optimistic UX” with an explicit escape hatch

AI edits are only useful if they’re fast, but speed without safety kills trust.

Aye Chat leans into an optimistic workflow: apply changes directly, but make rollback instantaneous.

• Every update creates snapshots automatically.
• diff is the review step.
• restore / undo is the safety net.

DX-wise, this shifts the mental model from “AI is risky” to “AI is reversible” and "I can experiment without fear". Developers move faster because the cost of being wrong is low.

4) Reduce cognitive load with “focus tools” instead of more UI

Two small primitives do a lot of work:

• @file references: include a file inline, on demand.
• with <files>: <prompt>: constrain the problem to specific files (supports wildcards).

This is progressive disclosure again: you don’t need to learn these on day one, but when prompts get vague, you have a precise way to tell the system what matters.

5) Interaction design for the terminal: make latency feel manageable

AI latency is real; good terminal UX acknowledges it instead of hiding it.

Aye Chat uses “progressive waiting” messages (spinner text that changes over time):

• “Building prompt…”
• “Sending to LLM…”
• “Still waiting…”

It’s a small thing, but it makes the experience feel responsive and honest.

6) Autocomplete as a DX feature (not a gimmick)

Terminal tools win when they help you stay in flow. Aye Chat’s completion behavior is designed for that:

• Multi-column completions for readability.
• Special-cased auto-complete for @file contexts.
• A user setting to choose “readline-like” vs “complete while typing”.

The principle here is consistency: the UI adapts to the terminal, not the other way around.

Takeaway

If you’re building AI for developers, UX principles like hierarchy, progressive disclosure, and reversible actions aren’t “nice to have.” They’re the difference between a demo and a daily driver.
