Augment (Auggie)

Happier integrates Augment using the Auggie backend/runtime.

Auggie is an experimental integration. It works and people use it daily, but its surface is younger than Claude, Codex or OpenCode and is more likely to change. What it supports today is in Agent capabilities.

Requirements

Auggie CLI installed locally.
Binary available on PATH (or set HAPPIER_AUGGIE_PATH).

Install Auggie

Happier can install it for you:

happier install provider auggie
auggie --version

Or install manually:

npm install -g @augmentcode/auggie
auggie --version

Local authentication in Happier

Auggie supports launching its native login flow from:

Settings → AI & Agents → AI backends → Auggie

Use that page to:

open auggie login directly inside Happier
re-run auth checks on the selected machine with Check now

Auth-status detection for Auggie is currently conservative. Happier may still show Unknown even though the login flow is available.

For the shared user guide, see Provider authentication.

Start Augment/Auggie with Happier

happier auggie

Notes

Resume availability is session-specific in Happier and depends on valid resume metadata plus the current backend/settings.
Modes, permissions, and model behavior can still vary by the installed runtime.
Session tools are normalized into canonical Happier timeline tools.

Troubleshooting

If Auggie is not detected:

Verify auggie --version works.
Restart Happier.
Set HAPPIER_AUGGIE_PATH if needed.
