Help me add a skill correctly in my setup. Always distinguish between:

1. Global skills (dotfiles-managed): shared across Claude, Codex, and Agents on any machine after stowing dotfiles.
2. Repo skills (project-local): only available inside the current repo for Pi/Agents to use.

First: Determine scope (default to global)

Assume global skill unless the user explicitly asks for a repo-local skill.

If the user does not specify scope:

• Proceed as global.
• Confirm skill name and purpose only.

If the user explicitly requests repo-local behavior, follow the repo workflow below.

A) Global skill workflow (dotfiles)

Architecture to follow

Global skills live in:

• ~/dotfiles/agent-skills/_shared-skills/<skill-name>/SKILL.md

Agent entry points:

• ~/.codex/skills -> stowed from ~/dotfiles/codex/dot-codex/skills (symlink to shared skills)
• ~/.agents/skills -> stowed from ~/dotfiles/codex/dot-agents/skills (symlink to shared skills)
• ~/.claude/commands -> stowed from ~/dotfiles/claude/dot-claude/commands (single symlink to ~/dotfiles/agent-skills/_claude-commands)
• ~/.claude/commands/<skill-name>.md -> ~/dotfiles/agent-skills/_claude-commands/<skill-name>.md -> shared SKILL.md

Steps

1. Create skill directory and file:
   • ~/dotfiles/agent-skills/_shared-skills/<skill-name>/SKILL.md
2. Add frontmatter with at least:
   • name, description (and optional argument-hint, allowed-tools)
3. If Claude should have it, add shim symlink in:
   • ~/dotfiles/agent-skills/_claude-commands/<skill-name>.md -> ../_shared-skills/<skill-name>/SKILL.md
4. Re-stow packages from ~/dotfiles:
   • stow claude codex
5. Verify resolution:
   • ~/.claude/commands/<skill-name>.md exists
   • ~/.codex/skills/<skill-name>/SKILL.md exists
   • ~/.agents/skills/<skill-name>/SKILL.md exists

B) Repo skill workflow (project-local)

Use this when a skill should only exist for one repository.

1. Create skill file in the repo’s local skills area (typically):
   • <repo>/skills/<skill-name>/SKILL.md
2. Add frontmatter and instructions specific to that project.
3. Do not add a dotfiles Claude shim.
4. Do not stow dotfiles for repo-only skills.
5. Verify Pi can discover it from the repo context.

Output expectations when I invoke this skill

• State clearly whether we are creating a global or repo skill.
• If scope was not specified, explicitly note that global was assumed by default.
• Show exact paths that will be created/edited.
• For global skills, include stow + verification commands.
• For repo skills, confirm this is intentionally local-only.
