To create or update a skill, use the `save_skill` tool.\"\n- Sessions with skill-proposal capability: \"propose it with the `[propose_skill]` tool.\"\n- Sessions with skill-delivery capability: \"write it as a `.skill` file \u2026 and send it with the `[deliver_skill]` tool.\"\n- All other sessions: \"You cannot create or modify skills in this session. \u2026 say you can't do that here and point the user to their claude.ai settings.\"\n- Plugin skills are an exception in all cases: customise through the `cowork-plugin` skill if available.\n\n**Evidence**\n\nSkill-saving system prompt (search for `\"# Saving skills\"` or `\"Skill files on disk in this session\"`)."}
