Codex Ops: React Migration Audit, Automation Tuning, Android Termux APK, and Markdown Chat Rendering

Codex Daily Tech Digest — Feb 22, 2026

A concise recap of the last 24 hours of Codex work (2026-02-21 to 2026-02-22).

Highlights

• Audited a Vue-based codex-web-local codebase to scope a safe React conversion path and map key API/types needed for a minimal React shell.
• Tuned automation workflows: daily digest title specificity, PR-fork merger conflict handling, and a new requirement to emit PROJECT_SPEC.
• Scoped UI polish and rendering improvements: GitHub-flavored Markdown in chat bodies and titles.
• Explored a mobile delivery path: building an Android APK bundling Termux + Codex with a WebView frontend, plus device testing steps.

What Changed and Why It Matters

React Migration Readiness for codex-web-local

Work centered on understanding the existing Vue app’s structure, entry points, routes, and API contracts so a React shell can be built without over-reaching. The ask focused on a minimal, safe conversion target (core shell first vs full parity), with explicit support for thread groups, thread selection, message loading, thread lifecycle (start/resume/interrupt/archive), and notifications. This creates a clearer migration plan and reduces the risk of rebuilding non-critical UI too early.

Automation Operations and Reliability

Several automation behaviors were refined. The daily digest automation was asked to produce more topic-rich titles (explicitly naming all major topics). The hourly PR-fork merger automation was directed to resolve conflicts instead of skipping them, and to output a PROJECT_SPEC artifact. These changes aim to make the automation output more actionable and reduce hidden manual follow-up.

Rendering & UX Improvements

A request was logged to add GitHub-style Markdown rendering in chat content and titles. This will improve readability of technical discussions (code blocks, lists, inline formatting) and align the UI with developer expectations.

Android Delivery Experiments

An Android packaging path was explored: an APK embedding Termux with Codex preinstalled, and a WebView frontend that connects to Termux. The work included a request to build and test the APK on device. This is an early step toward a mobile-friendly Codex distribution.

Quick Notes

• A skills search was initiated for Vue-related capabilities.
• A web search was requested to trace upstream codegen origins.
• Automation storage locations were queried to improve operator workflows.
• Flight price tracking automation ran as scheduled.

Next Moves

• Decide on the React migration target (core shell vs full parity).
• Scope the Markdown rendering work (parser + sanitization + UI integration).
• Prototype the Android Termux + WebView packaging flow for repeatable builds.
