Sim v0.6.56 Adds AgentPhone Integration and Better Subagent Visibility

Sim v0.6.56 delivers a focused product update aimed at agent usability, file management, and operational reliability. The release adds AgentPhone integration, improves how subagent logs are displayed in the UI, and refines file sorting behavior, while also fixing issues in image rendering, table resizing, API responses, and data retention handling.

What Changed

The most visible feature in v0.6.56 is a new bounded vertical log view for subagents in the UI. This should make multi-agent workflows easier to monitor by keeping logs readable and contained within a cleaner interface. For teams running complex automations or supervising multiple agents, that is a practical quality-of-life improvement.

The release also adds AgentPhone integration, extending Sim's connectivity into another agent interaction surface. While the changelog is brief, this suggests the platform is continuing to expand how agents can connect to external interfaces and communication layers.

File management also gets an upgrade in this version. Files now sort by updated time by default, and users can explicitly choose an updated-sort option. That improves usability for active projects where the newest artifacts matter most.

Why It Matters

Beyond the headline features, v0.6.56 includes a set of bug fixes that improve reliability in day-to-day use. AgentPhone image handling was fixed, reducing friction in media-related workflows. Table auto-resize behavior now better accounts for letter spacing and displayed content, which should make data-heavy interfaces render more accurately.

On the backend and governance side, the API now passes archivedAt in list table responses, which is useful for downstream tooling and lifecycle-aware interfaces. Data retention has also been shifted to the organization level, a meaningful change for teams that need more consistent policy control across users and resources.

The release also sets a 90-second statement timeout, indicating attention to database safety and query control. That kind of operational tuning matters for keeping application performance predictable as workloads grow.

Overall, Sim v0.6.56 is less about a sweeping platform overhaul and more about tightening the product in the places users feel every day: agent observability, file recency, interface correctness, and org-level operational controls.
