Codex Configuration Log

A running list of configuration changes and tweaks used to optimise my Codex setup for agentic research and coding tasks.

System Settings & Tooling

This page documents the technical configurations and environment choices that power my agentic coding workflow. Instead of a chronological log, settings are grouped by category to help track the evolution of the system.

Agent Capabilities & Features

Web Search Tooling Adopted: 2026-01-14

Enabling the web_search_request feature allows the agent to call the web_search tool. This is essential for verifying up-to-date documentation and fetching real-time data during research tasks.

Configuration change:

File: ~/.codex/config.toml

[features]
web_search_request = true

Rationale: Reduces hallucinations by allowing the agent to verify facts against live web data rather than relying solely on training data.

Execution Environments

VS Code + WSL (Remote Integration) Adopted: 2026-01-14

Testing Codex performance when running within Windows Subsystem for Linux (WSL) via VS Code remote sessions. Focus areas include:

  • Responsiveness: Evaluating latency and "feel" compared to native Windows execution.
  • IDE Integration: Leveraging VS Code's native UI (file explorer, integrated terminal) as a steering layer for complex agentic tasks.

Future Roadmap

Planned entries for AGENTS.md system prompt refinements, TODO.md task orchestration patterns, and token budget management.
