Use this skill when the user wants to create, update, or troubleshoot custom subagent roles backed by [agents. ] and a role configfile.
This skill installs the role into /.codex/config.toml (or a user-selected project config), writes the role-specific config file, and validates key support against codex-rs/core/config.schema.json.
Default behavior is strict-minimal: configure only model, modelreasoningeffort, and developerinstructions unless the user explicitly asks for additional parameters.
Create and install Codex custom agent roles in ~/.codex/config.toml, generate role config files, enforce supported keys, and guide users through required role inputs (model, reasoning effort, developer_instructions). Source: am-will/codex-skills.
