From 7df110e25ec3d4e62df2cc9a7568c7fb6a2c6091 Mon Sep 17 00:00:00 2001 From: "sentry-junior[bot]" <264270552+sentry-junior[bot]@users.noreply.github.com> Date: Tue, 3 Nov 2026 14:50:54 +0000 Subject: [PATCH] perf(workspaces): List Workspaces in the turn context The agent could not see which Workspace covers a repository, so repo work ran searchTools, a rejected github_cloneRepository, then switchWorkspace. List each Workspace and its repositories in the bootstrap turn context so the agent can switch first, before it does sandbox work that the switch throws away.
