Issue 151: Remote SSH (Living Execution)

• cmux ssh creates remote workspace metadata and does not require --name
• Remote daemon bootstrap/upload/start path with cmuxd-remote serve --stdio
• Reconnect/disconnect controls (CLI/API/context menu) + improved error surfacing
• Retry count/time surfaced in remote daemon/probe error details
• Remove automatic remote service port mirroring (ssh -L from detected remote listening ports)
• Add transport-scoped proxy broker (SOCKS5 + HTTP CONNECT) for remote traffic
• Extend cmuxd-remote RPC beyond hello/ping with proxy stream methods (proxy.open|close)
• Auto-wire WKWebView in remote workspaces to proxy via WKWebsiteDataStore.proxyConfigurations
• Add browser proxy e2e tests (remote egress IP, websocket, reconnect continuity)
• Implement PTY resize coordinator with tmux semantics (smallest screen wins)
• Add resize tests for multi-attachment sessions (attach/detach/reconnect transitions)

Socket API / Agent

• Add window handles + window.list/current/focus/create/close for multi-window socket control (v2) + v1 equivalents (list_windows, etc) + CLI support.
• Add surface move/reorder commands (move between panes, reorder within pane, move across workspaces/windows).
• Add browser automation API inspired by vercel-labs/agent-browser, but backed by cmux's WKWebView (wait, click, type, eval, screenshot, etc.).
• Finalize browser parity contract and command mapping decisions in docs/agent-browser-port-spec.md.
• Add cmux browser command surface that mirrors agent-browser semantics and targets explicit surface_id handles.
• Add short handle refs (surface:N, pane:N, workspace:N, window:N) and CLI --id-format refs|uuids|both output control.
• Add v1->v2 compatibility shim for migrated browser/topology commands while v1 remains supported.
• Port browser automation coverage to tests_v2/ per docs/agent-browser-port-spec.md and keep v1 + v2 suites green.
  • Added tests_v2/test_browser_api_comprehensive.py, tests_v2/test_browser_api_p0.py, tests_v2/test_browser_api_extended_families.py, tests_v2/test_browser_api_unsupported_matrix.py, and tests_v2/test_browser_cli_agent_port.py.
  • Full VM runs: ./scripts/run-tests-v1.sh and ./scripts/run-tests-v2.sh passing (v2 visual D12 remains reported as a known non-blocking VM failure, matching v1 policy).
• Fix cmux browser open|open-split|new URL parsing so routing flags (--workspace, --window) are removed before URL construction.
• Fix identify --workspace/--surface caller parsing to honor ref handles (workspace:N, surface:N) instead of falling back to current/focused IDs.
• Update browser.open_split placement policy: reuse nearest right sibling pane first (nested-aware), only create a new split when caller has no right sibling.
• Upgrade browser.snapshot to agent-browser-style output (snapshot tree text + refs) and make non-JSON CLI output print snapshot content instead of OK.
• Add richer selector failure diagnostics (hint, counts, sample, snapshot excerpt) with bounded retries for transient not_found races.
• Add regression coverage for browser placement policy + snapshot/ref output + diagnostics in v2 tests.
• Allow browser fill with empty text (clear input) in CLI + v2 API flows.
• Make legacy new-pane/new-surface CLI output prefer short surface:N refs by default.
• Add optional --snapshot-after / snapshot_after action feedback to include a fresh post-action browser snapshot.
• Switch CLI --json default ID output to refs-first (UUIDs only via --id-format uuids|both) and add regression coverage.
• Expand end-user skill docs with deep-linkable cmux-browser references/templates plus a new core skills/cmux/ topology skill.

Command Palette

• Add cmd+shift+p palette with all commands

Feature Requests

• Warm pool of Claude Code instances mapped to a keyboard shortcut

Claude Code Integration

• Add "Install Claude Code integration" menu item in menubar
  • Opens a new terminal
  • Shows user the diff to their config file (claude.json, opencode config, codex config, etc.)
  • Prompts user to type 'y' to confirm
  • Implement as part of cmux CLI, menubar just triggers the CLI command

Additional Integrations

• Codex integration
• OpenCode integration

Browser

• Per-WKWebView proxy observability/inspection once remote proxy path is shipped (URL, method, headers, body, status, timing)

Bugs

• P0 Terminal title updates are suppressed when workspace is not focused (e.g. Claude Code loading indicator doesn't update in sidebar until you switch to that tab)
• Sidebar tab reorder can get stuck in dragging state (dimmed tab + blue drop indicator line visible) after drag ends
• Drag-and-drop files/images into terminal shows URL instead of file path (Ghostty supports dropping files as paths)
• After opening a browser tab, up/down arrow keys (and possibly other keyboard shortcuts) stop working in the terminal
• Notification marked unread doesn't get pushed to the top of the list
• Browser cmd+shift+H ring flashes only once (should flash twice like other shortcuts)

Refactoring

• P0 Remove all index-based APIs in favor of short ID refs (surface:N, pane:N, workspace:N, window:N)
• P0 CLI commands should be workspace-relative using CMUX_WORKSPACE_ID env var (not focused workspace) so agents in background workspaces don't affect the user's active workspace. Affected: send, send-key, send-panel, send-key-panel, new-split, new-pane, new-surface, close-surface, list-panes, list-pane-surfaces, list-panels, focus-pane, focus-panel, surface-health
• P0 Remove close-workspace with no args — require explicit workspace short ID or UUID, with clear error message if missing

UI/UX Improvements

• Show loading indicator in terminal while it's loading
• Add question mark icon to learn shortcuts
• Notification popover: each button item should show outline outside when focused/hovered
• Notification popover: add right-click context menu to mark as read/unread
• Right-click tab should allow renaming that workspace
• Cmd+click should open links in cmux (browser panel) instead of external browser
• "Waiting for input" notification should include custom terminal title if set
• Close button for current/active tab should always be visible (not just on hover)
• Add browser icon to the left of the plus button in the tab bar

Analytics

• Add PostHog tracking (set PostHogAnalytics.apiKey in Sources/PostHogAnalytics.swift)

Browser Parity Completion (agent-browser port)

• Implement locator family:
  • browser.find.role
  • browser.find.text
  • browser.find.label
  • browser.find.placeholder
  • browser.find.alt
  • browser.find.title
  • browser.find.testid
  • browser.find.first
  • browser.find.last
  • browser.find.nth
• Implement frame/dialog/download:
  • browser.frame.select
  • browser.frame.main
  • browser.dialog.accept
  • browser.dialog.dismiss
  • browser.download.wait
• Implement session/context state APIs:
  • browser.cookies.get|set|clear
  • browser.storage.get|set|clear
  • browser.tab.new|list|switch|close
  • browser.state.save|load
• Implement developer/diagnostic helpers:
  • browser.console.list|clear
  • browser.errors.list
  • browser.highlight
  • browser.addinitscript
  • browser.addscript
  • browser.addstyle
• Add explicit not_supported for WebKit/CDP-gap commands:
  • browser.viewport.set
  • browser.geolocation.set
  • browser.offline.set
  • browser.trace.start|stop
  • browser.network.route|unroute|requests
  • browser.screencast.start|stop
  • browser.input_mouse|input_keyboard|input_touch
• Extend cmux browser ... CLI grammar for the new families (including aliases).
• Port/add v2 tests for all newly implemented families.
• Update unsupported matrix tests to assert not_supported for hard platform gaps (instead of method_not_found).
• Re-run full run-tests-v1.sh and run-tests-v2.sh on cmux-vm.
