ai-sandbox: rotating Git source credentials changes the sandbox key #1468

Description

@HCaupert

TanStack AI version

@tanstack/ai@0.58.0, @tanstack/ai-sandbox@0.5.12, @tanstack/ai-sandbox-docker@0.3.2 (npm latest versions when tested).

Framework/Library version

No UI framework. Bun 1.4.2 on Linux.

Describe the bug and the steps to reproduce it

Changing only gitSource({ auth: { token } }) changes the sandbox instance key, even with the same threadId, sandbox ID, repository, and reuse: 'thread'.

This comes up with GitHub App installation tokens, which expire after one hour. Renewing the token changes the lookup key, so a later run cannot find the previous sandbox record even if its container is still available.

To reproduce, download the three files from the gist below and run:

bun install
bun repro.ts

The script computes keys before and after changing a Git token, then does the same for a workspace secret. It does not create a sandbox or make any network requests; no Docker daemon or real credentials are needed to run it.

Actual output:

Git token rotation changes key: true
Workspace secret rotation changes key: false

Expected: both comparisons return false. Renewing a credential with equivalent access should not by itself invalidate sandbox reuse.

In computeWorkspaceHash(), workspace.secrets is excluded, but source.auth.token remains in the hashed object. gitSource accepts a string token and bootstrap forwards it directly to handle.git.clone().

The provisioning guide documents SecretRef authentication for gitSkill, but the main workspace source does not accept it. Is there a supported way to use rotating credentials for the main Git source without changing its sandbox key?
