A busy week across the harness, the new Voss ADE desktop shell, and the underlying memory and review loops.

​
New features

​
Voss ADE desktop shell

The Voss app is now branded Voss ADE and ships with platform-native window effects, a polished pane chrome, and a new appearance system. You can switch themes, reduce motion, and manage settings profiles from the command palette or native menu.
  • Workspace tab bar — open multiple workspaces side by side, rename and reorder tabs, and color-code them so you can tell projects apart at a glance.
  • New workspace picker — create or open a workspace with a keyboard shortcut, or from the command palette.
  • Five bundled themes — light, dark, and three new accent themes, validated against the theme schema so custom themes won’t break the UI.
  • Status bar — a dedicated bar surfaces session, PID, and notification state, with dual-buffer notifications so transient messages don’t clobber persistent ones.

​
Durable agent sessions

Agent sessions now persist across app restarts. The ADE keeps a SQLite-backed registry of every agent pane, restores PTY scrollback, and cleans up workspaces on quit so you can pick up exactly where you left off — even after a crash or reboot. See Sessions for the harness-side commands. Project memory now combines BM25 lexical scoring with Chroma vector search using Reciprocal Rank Fusion. The result is noticeably better recall on identifier-heavy queries (function names, file paths, error strings) without losing semantic matches. No configuration required — it’s on by default. Background in Project cognition.

​
Skill bundles

The harness can now discover, install, verify, and trust third-party .voss skill bundles from the CLI. New commands let you list installed skills, install a bundle, and manage trust. voss doctor also surfaces a gate-only confinement caveat so you can tell when a skill is sandboxed.

​
Command palette and tmux-style keymap

The ADE has a typed command registry, a fuzzy-matching command palette, and a tmux-style prefix-mode state machine with a pane-header indicator. You can drop workspace-local keymap overrides into your project and they’ll hot-reload as you edit them.

​
Updates

  • Project open flow — a new Setup window lets you pick a project folder from a native dialog and shows your recent projects. The titlebar updates dynamically to reflect the active project.
  • Toast notifications — a stacked toast system surfaces keymap validation errors and other transient feedback without blocking your work.
  • Engineering Manager loop — the autonomous EM coroutine now runs a full plan-tick cycle with structured LLM planning, gate predicates, and a Kanban board that enforces WIP caps and tracks card lifecycle. Reviewer responsibilities are split into a verification-authoring Reviewer A and a separate judge.
  • Audit harness — a new audit package captures session lineage and exit reasons for post-hoc analysis of agent runs.
  • MCP server bridge — Voss can now act as an MCP host, with vdiff tooling and inspect modals for examining tool calls.

​
Bug fixes

  • Fixed a BM25 recall fallback so hybrid search stays stable when the lexical index is cold.
  • Cleared a lingering blocked-state timer on pane unmount so panes don’t get stuck mid-drag.
  • Bumped the Vite build target from safari13 to safari15 to unblock layout-preset builds.
  • Added a session-persistence timeout on quit so the app no longer hangs on shutdown when the registry is busy.
