Codex Agent Setup

Explicit-only installer for the Product Skills Anthony and Caal Codex custom agents. Use ONLY when the user explicitly asks to install, update, check, uninstall, or set up Product Skills agents in Codex, including "install Anthony in Codex", "install Caal in Codex", "update the Product Skills Codex agents", or "check product_skills_legal". Never auto-invoke for ordinary legal, compliance, SOC 2, SEO, marketing, CRO, copywriting, or launch work.

File contents

Product Skills Codex Agent Setup

Install the generated Anthony and Caal Codex adapters as regular files. Run this skill only after an explicit request to install, update, check, or uninstall these agents.

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 product-skills-legal.toml and product-skills-marketer.toml, recording ownership in .product-skills-agents.json. Unmanaged collisions and symlinks are refused unless the user explicitly authorizes --force.

After a successful install or update, tell the user to start a new Codex session, then invoke Anthony as product_skills_legal or Caal as product_skills_marketer.
