Codex Inner IDE v0.4.4 Preview

Codex Inner IDE v0.4.4 Preview

Highlights

• Restores stdout and stderr when the current Codex App Server returns
  buffered command output without streaming every output event.
• Applies the shared output reconciliation path to Python, Java, JavaScript,
  and TypeScript without duplicating streamed output.
• Reports explicit Output status for HTML, CSS, and Markdown previews while
  retaining JSON validation output.
• Keeps the development Demo Host honest: command runtimes now state that code
  was not executed instead of showing a false successful Ran … result.
• Adds persistent Edit with Codex states for generating, ready, applied,
  rejected, cancelled, stale, and failed proposals.

Verification

• Frontend unit tests and production build.
• Swift unit, loopback, Preview, security, and App Server integration tests.
• Real Python and JavaScript stdout execution through the bundled Codex App
  Server; Java and TypeScript use the same reconciled command-output path.
• Independent macOS Release build, strict deep signature validation, archive
  integrity checks, and public Release asset reverse verification.

Codex Inner IDE v0.4.3 Preview

Codex Inner IDE v0.4.3 Preview

Highlights

• Adds a validated compatibility profile for Codex Desktop 26.721.41059
  build 5848 with bundled codex-cli 0.146.0-alpha.3.1.
• Enables the existing Browser-first IDE route for the new compatibility
  profile, with authenticated readiness and automatic native-window fallback.
• Opens and focuses the built-in Browser tab with an explicit CDP user gesture
  for the updated popup behavior.
• Opens and focuses the built-in Browser tab with a scoped CDP user gesture;
  other renderer evaluations remain non-user-gesture operations.
• Retains all v0.4.2-preview CDP recovery, Workspace, runtime, completion,
  Setup, theme, sidebar, loopback Bridge, and security behavior.
• Keeps support for all previously validated Codex Desktop profiles.

Compatibility evidence

• The installed ASAR retains the Sidepanel, composer, Quick Chat,
  selected-text overlay, and avatar-overlay markers used by desktop-v1.
• The bundled CLI retains codex app-server and stdio transport.
• The installed Codex bundle passes strict deep signature verification.
• Compatibility, frontend, Swift, live Browser, and App Server integration
  checks run against the installed Codex build before packaging.

Codex Inner IDE v0.4.2 Preview

Codex Inner IDE v0.4.2 Preview

Fixes

• Restores Browser-first IDE opening after the Companion restarts while Codex
  Desktop 26.721.30844 is already running.
• Recovers and validates Codex's active random loopback CDP port from the
  running process instead of requiring another Codex relaunch.
• Treats the authenticated Browser clientReady handshake as the source of
  truth because this Codex build can return null from window.open after
  successfully creating the built-in Browser tab.
• Extends the Browser startup allowance to 12 seconds while retaining native
  fallback when the authenticated handshake does not arrive.

Validation

• Live CDP discovery and WebSocket connection against Codex Desktop
  26.721.30844 build 5813.
• Real Open IDE handoff into the Codex built-in Browser.
• Real Workspace, file tree, Monaco editor, and local runtime state loaded
  without a Mock Host fallback.
• Frontend tests, Swift tests, Release build, archive validation, and signature
  verification.

  codex-cli 0.146.0-alpha.3.
• Enables the existing Browser-first IDE route for the new compatibility profile,

• Retains all v0.4.0-preview multi-language runtime, completion, Workspace,
  Setup, theme, sidebar, authenticated loopback Bridge, and security behavior.

• The installed ASAR retains the Sidepanel, composer, Quick Chat,
  selected-text overlay, and avatar-overlay markers used by desktop-v1.

Codex Inner IDE v0.4.0 Preview

Codex Inner IDE v0.4.0 Preview

Highlights

• Browser-first real IDE for validated Codex Desktop builds, with automatic native-window fallback.
• Authenticated loopback HTTP bridge on a random port, token-in-fragment bootstrap, streaming events, Origin checks, a 16 MiB request limit, and restrictive CSP.
• Multi-client dirty state, active edit context, Save All coordination, heartbeat, disconnect, and service-restart handling.
• Python, Java, JavaScript, TypeScript, HTML, CSS, JSON, Markdown, and Plain Text language actions.
• Structured missing-runtime Setup guidance with copy-only commands, official downloads, and live Recheck.
• Java discovery through JAVA_HOME, Workspace .jdk, system JDKs, Homebrew, and PATH.
• Multi-language local completion, recent Workspace switching, redesigned file tree, collapsible sidebar, and Auto / Light / Dark themes.
• Development Vite mode is explicitly labelled Demo host; demo runtimes no longer appear as real installed environments.

Security boundaries

• The Companion App binds only to 127.0.0.1.
• Browser workspace APIs require the per-process token and same-origin requests.
• Runtime setup commands are never executed by the IDE.
• The Codex app, ASAR, signature, and private IPC are not modified.
• The native WKWebView Bridge and Unix Socket MCP Bridge remain available.

Compatibility note

The authenticated Browser page and native fallback were live-validated with
Codex Desktop 26.715.72359. The injected Sidepanel-to-Browser handoff remains
version-gated preview behavior because it requires a user-approved Codex relaunch
with a random loopback-only CDP port. Unknown versions and failed handshakes use
the native IDE.

Codex Inner IDE v0.3.0 Preview

Codex Inner IDE v0.3.0 Preview

Adds explicit, Enter-approved Python edit proposals and time-adaptive IDE colors.

Changes

• Adds the repo-local codex-inner-edit Skill and stdio MCP server.
• Generates proposals in an ephemeral Codex App Server turn with readOnly, approvalPolicy: never, and network access disabled.
• Shows inline Monaco additions/removals; Enter applies one undoable buffer edit, Esc rejects, and only ⌘S writes to disk.
• Rejects stale buffers, non-Python or read-only files, oversized contexts, malformed dynamic-tool responses, and concurrent proposals.
• Adds a same-UID, token-authenticated Unix socket between the plugin MCP process and the running controller; tool results never include source code.
• Automatically uses a light IDE theme from 07:00–18:59 local time and a dark theme from 19:00–06:59.
• Adds a per-workspace Pin control that keeps the IDE window above other apps until unpinned.
• Removes Add to chat and keeps More details as the single selection handoff, with updated Quick Chat composer discovery.
• Detects missing or stale Codex CDP sessions when More details is used, requests an explicit Codex relaunch, and falls back to the clipboard when relaunch is declined or unavailable.

  packaged ASAR markers inspected locally.

• Live CDP Sidepanel and chat handoff verification remains pending because it
  requires an explicit Codex relaunch.

Preview limitations

• Apple Silicon and macOS 14 or newer.
• Ad-hoc signed and not Apple-notarized.
• Version-bound CDP and UI selectors may break after a Codex update.
