What is the process to edit Codex agent model routing and session capabilities?▼

Editing Codex agent model routing involves using the agent-env-codex skill to modify the harness configuration, allowing you to toggle specific session capabilities and update routing rules for your agents.

Do I need Rust and envctl installed to customize the Codex agent environment?▼

Yes, you need Rust and the envctl toolchain installed, as the agent-env-codex skill requires Rust and associated tooling to build and run the Codex agent harness for customizations or bug fixes.

Can I automate the workflow to repair or upgrade the Codex agent harness?▼

Yes, you can automate harness repairing and upgrading workflows using the agent-env-codex skill, which provides scripts to manage and toggle specific harness capabilities without manual intervention.

What's the best way to update active-skill materialization in a Codex harness?▼

The best way to update active-skill materialization is by using the agent-env-codex skill to edit or rebuild the Codex harness, ensuring the active skills are correctly materialized into the agent environment.

Why does modifying the Codex harness require rebuilding the Rust code?▼

Modifying the Codex harness requires rebuilding the Rust code because the envctl agent harness is compiled, meaning structural changes to agents, teams, or rules need a rebuild to take effect in the environment.
