Switch codex skills from deprecated custom prompts to ~/.agents/skills SKILL.md - #390
Merged
Conversation
…s SKILL.md Custom prompts (~/.codex/prompts/) are deprecated upstream and are only user-typed slash commands — the model never discovers them, so a codex task cannot self-advance its workflow. Switch to codex's model-discoverable skills mechanism: ~/.agents/skills/<name>/SKILL.md (user scope, so nothing reaches the working tree). Adds write_agent_skills / write_agent_operation_skills to container/skills.py with the name+description frontmatter the skills surface requires; updates CodexAgentCLI to call them; removes the now-unused PROMPTS_SUBDIR; updates test_codex.py path pins.
