A local app is a small tool the agent builds once and Tidebreak keeps in the Apps library. Ask for a triage view, review console, or other focused interface in a chat; when the agent publishes it, the app outlives that chat and can be reopened from the sidebar.
Apps are versioned. Publishing another revision appends to the app's history instead of replacing the old record in place.
What an app contains
Each revision has two parts:
- An HTML, CSS, and JavaScript bundle authored by the model.
- A manifest naming the exact capabilities the app needs: selected operations from REST connected apps, connected folders, or apps granted through an organization's model gateway.
The bundle is untrusted. The manifest is the part you review and consent to. Tidebreak enforces it on every call, regardless of what the app's interface claims it can do.
Opening and granting one
Open Apps in the sidebar and choose an app. The first open—and any open after its capability set changes—shows a consent sheet before the app runs. Review the named folders, connected apps, and exact operations, then grant or decline access.
Consent belongs to that app, not to a chat permission mode. You can revoke it from the app's detail view. If a bound connected app is reconfigured, or a new revision asks for more access, the existing grant stops matching and Tidebreak asks again.
Containment
The app runs in a sandboxed, opaque-origin frame with a strict content security policy. It has no direct network access, cannot read Tidebreak's DOM or local storage, and never receives provider or connected-app credentials.
When the app invokes a granted operation, it sends a message to the trusted host. The host checks the current manifest and consent, injects credentials at request time, executes the operation, bounds the result, and returns only the result to the frame.
An app can still render misleading text—the bundle is model-authored—so treat its interface as presentation, not authority. The server-side manifest and grant are the actual boundary.
Managing apps
The Apps library shows every live app, its revision count, last update, and whether access is granted. Open an app to run it, inspect or revoke access, review its revision history, or delete it.
