Sigma Auth Codex Agent Setup

Install Siggy's generated Codex adapter as a regular file. Run this skill only after an explicit request to install, update, check, or uninstall Siggy.

Safety contract

• Default to the current project's .codex/agents/ directory.
• Use --user only when the user explicitly requests a user-wide install.
• Never edit ~/.codex/config.toml or any global Codex configuration.
• Never create plugin-cache symlinks or delete unrelated custom agents.
• Run --check when the user asks what would change.

Commands

bash "${SKILL_DIR}/scripts/setup.sh" [--check|--uninstall|--force]
bash "${SKILL_DIR}/scripts/setup.sh" --user [--check|--uninstall|--force]
bash "${SKILL_DIR}/scripts/setup.sh" --target /custom/agents/directory

The installer manages only sigma-auth-guide.toml and records ownership in .sigma-auth-agents.json. An unmanaged collision is refused unless the user explicitly authorizes --force.

After a successful install or update, tell the user to start a new Codex session, then invoke Siggy using the runtime name sigma_auth_guide.
