Codex CLI 0.115.0: Image Detail, Realtime v2, Filesystem APIs

TL;DR

• Full-resolution image inspection now available via detail: "original" for precision visual tasks
• Realtime websocket sessions gain dedicated transcription mode and v2 handoff support
• App-server filesystem RPCs for reads, writes, copies, and directory ops; new Python SDK included
• Smart Approvals now route through guardian subagent, reducing repeated setup work

New

• Full-resolution image inspection — Models can now request original-detail images through view_image and codex.emitImage(..., detail: "original") for tasks requiring pixel-level precision.
• js_repl helpers persistence — codex.cwd, codex.homeDir, and saved tool references now persist across cells, eliminating repeated setup.
• Realtime v2 transcription mode — Websocket sessions support dedicated transcription mode plus unified [realtime] session config for cleaner v1/v2 handoff.
• App-server filesystem RPCs — New v2 APIs expose file reads, writes, copies, directory operations, and path watching. Python SDK included for integration.
• Smart Approvals guardian routing — Review requests now route through a guardian subagent in core, app-server, and TUI, cutting setup overhead on follow-up approvals.
• App integrations tool search — Integrations now use Responses API tool-search flow, can suggest missing tools, and gracefully fall back when models don't support search-based lookup.

Fixed

• Subagent sandbox inheritance — Spawned subagents now reliably inherit sandbox and network rules, including project-profile layering, persisted host approvals, and symlinked writable roots.
• js_repl Unicode hang — Fixed hang when dynamic tool responses contain literal U+2028 or U+2029 characters.
• TUI exit stall — TUI no longer stalls on exit after creating subagents; interrupting a turn preserves background terminals by default.
• Profile-scoped settings — codex exec --profile now preserves profile-scoped settings when starting or resuming a thread.
• MCP and elicitation robustness — Safer tool-name normalization and preserved tool_params in approval prompts.
• HTTP proxy compatibility — Local network proxy now serves CONNECT traffic as explicit HTTP/1, improving compatibility with HTTP proxy clients.

Chores

• Subagent tool naming — The multi-agent wait tool is now consistently named wait_agent, aligning with spawn_agent and send_input.
