Trebell Code Desktop v1.3.0

Trebell Code 1.3 is the large post-1.2 parity and reliability release. It expands Trebell from a Codex-centered desktop shell into a multi-harness coding workspace while tightening the workflows around background agents, worktrees, browsers, terminals, source control, updates, and provider compatibility.

Multi-harness runtime support

  • Runtime profiles for Codex, Claude Code, Cursor, Grok Build, OpenCode, and Antigravity.
  • Multiple configured instances per harness, with runtime-specific probing, authentication/status reporting, model discovery, and isolated homes where supported.
  • Local, WSL, and SSH environment support for agent execution and workspace access.
  • Provider-agnostic usage tracking and restart recovery across supported runtimes.

Background and multi-model work

  • Ctrl+Enter / Cmd+Enter starts a new task in the background so the composer is immediately free for another prompt.
  • Shift-click models in a new-thread model picker to send the same task to multiple models.
  • Each selected model receives its own isolated Git worktree and thread.
  • Fan-out validates that the project is a Git checkout with a real base branch and rejects detached-HEAD launches.
  • Partial failures preserve the failed prompt in Trebell Stash. Ambiguous RPC failures attempt to recover the possibly-started thread by its unique worktree path and warn before retrying, reducing duplicate background work.

Project and worktree parity

  • Per-project identity with automatic monograms, emoji, custom monograms, colors, or imported images.
  • Project model, permissions, workspace, worktree-submodule, cleanup, and project-action overrides.
  • T3-compatible worktree submodule modes: recursive, top-level, and none, including t3.json inheritance.
  • Safe managed-worktree cleanup with inactivity, merged-branch, last-thread-deletion, and unchanged-from-base rules.
  • Dirty worktrees, active agent paths, running terminal paths, and non-Trebell worktrees are never automatically removed.
  • Cleaned managed worktrees retain their branch metadata and are recreated automatically when reopened.
  • Project actions can be saved, imported from t3.json / package.json, run during worktree setup, wait for setup completion, and open preview URLs.

Codex capability surfaces

  • MCP server status, skills, plugins, plugin marketplaces, plugin sharing, apps/connectors, hooks, experimental features, configuration layers, account/usage information, and provider capabilities are exposed through Trebell's Harness Tools UI.
  • Connector detail inspection includes tool summaries instead of presenting connectors as dead list items.
  • Plugin sharing supports save, checkout, delete, discoverability, and target updates using the bundled Codex app-server's real RPC contracts.

Browser, desktop, and device tools

  • Isolated Agent Browser with navigation, DOM snapshots, click/type, screenshots, responsive viewport controls, cookies, recording permission, annotations, and localhost preview discovery.
  • One-time browser-profile import for Firefox and Helium on Windows. Other Chromium browsers remain intentionally excluded because their cookies use app-bound encryption that Trebell does not bypass.
  • Desktop screenshot context plus explicit full-access mouse, keyboard, scroll, and typing controls for agent computer use.
  • Android emulator and iOS simulator discovery/control surfaces, with separate opt-in agent access.
  • Global SnapShot shortcut with optional accessibility-text capture and local pending-capture recovery.

Terminal, source control, and review workflow

  • Persistent terminal scrollback survives app restarts as stopped history rather than pretending stale PTYs are still running.
  • Git branches, worktrees, status, commit/push/pull/fetch, PR creation/review/comments/merge/update/checkout, multi-forge detection, and diagnostics remain integrated in the workspace.
  • Review comments, checkpoints, rewind/revert support where the active harness exposes it, linked pull requests, and diff/file review state are retained across the streamlined workspace UI.

Reliability and desktop experience

  • Restart continuation can recover supported active threads after Trebell restarts; it remains opt-in to avoid silently resuming work.
  • Provider switching no longer leaves a stale model catalog visible while the harness restarts.
  • Non-Freebuff compatibility bridges now use per-instance dynamic loopback ports, preventing multiple Trebell instances/tests from fighting over one hard-coded socket.
  • Firefox/Helium import, attachment ceilings, remote attachment streaming, conditional keybindings, open-in-editor integration, license browsing, custom theme import/export, appearance modes, usage/cost views, and background tray mode are covered by the current test suite.
  • One-click packaged desktop updates now check GitHub releases, download through electron-updater, show progress, and install/restart only after explicit user confirmation. Normal app quit never silently installs a downloaded update.

Provider validation

  • Freebuff, AgentRouter, Vyce AI, JustWorker, and HCNSec integrations remain available to the Codex harness where configured.
  • AgentRouter keeps the Codex-compatible request fingerprint required by its current gateway and uses the Responses API.
  • Vyce live model discovery is tested against the configured account.
  • A live two-model fan-out smoke test ran deepseek-v4.1 and agnes-3.0-flash through Trebell's real bundled Codex app-server in separate Git worktrees. Both threads completed and returned the expected proof marker.

Run the reusable live fan-out check from trebell-code:

npm run test:vyce:fanout

Pre-release validation

  • Node unit/integration suite: 103/103 passing.
  • Playwright desktop-style harness flow: passing.
  • Real bundled Codex app-server browser relay integration: passing.
  • Real Windows DPAPI round-trip and Firefox/Helium cookie-import tests: passing.
  • Real temporary Git repository tests for worktree creation, cleanup protection, merge/inactivity rules, and restoration: passing.
  • Live Vyce multi-model fan-out through the Trebell + Codex harness: passing.

The Windows release pipeline additionally builds and launches the unpacked packaged app, validates the bundled Codex relay and desktop surfaces, runs a packaged model-driven harness check when Vyce credentials are available, produces NSIS update metadata (latest.yml + blockmap), and then publishes the installer and updater assets to GitHub.
