Do not use this for ordinary Markdown documentation, one-off task notes, or company-owned skills under `~/.agents/skills/projects/`. ## Ownership and placement - Non-project directories under `~/.agents/skills/` are the open-source/private skill source tree; edit them directly with `write` or `edit`, preserving their category and existing conventions. - `~/.agents/skills/projects/` is company-owned and remains a direct child of the skills root. Never create, edit, delete, or reformat files there from this skill. - Shared skills may live under category directories such as `core/`, `planning/`, or `operations/`; category paths are organizational, not aliases. Preserve one canonical directory per skill and update references after moves. - `skill_manage` creates skills in its managed store; it is not a substitute for editing this repository source tree. - Before editing, read applicable `AGENTS.md` files and the target skill body. ## Procedure 1. **Check for an existing skill.** Search by trigger, name, and behavior.
