Implement Skill

If $ARGUMENTS is provided and matches a skill name in output/, use it directly.

If $ARGUMENTS is not provided or doesn't match, show the list from Phase 1 and ask the user to pick by name or number.

Phase 3: Validate

Run the validation script on the selected skill before installing:

python "${CLAUDE_SKILL_DIR}/../validate-skill/scripts/quick_validate.py" output/<skill-name>

If validation reports any FAIL, warn the user and ask if they want to proceed anyway or fix the issues first.

If validation passes, proceed to install.

Phase 4: Install

4a: Check for existing installation

Check if ~/.claude/skills/<skill-name>/ already exists.

If it exists — show a comparison:

## Skill already installed globally

**[skill-name]** exists at `~/.claude/skills/[skill-name]/`.

| | Global (current) | Output (new) |
|---|---|---|
| Files | [count] | [count] |
| SKILL.md lines | [count] | [count] |
| Description | [first 80 chars] | [first 80 chars] |

Ask: "Overwrite the global version with the one from output/? (y/n)"

• If user confirms → proceed to 4b
• If user declines → abort with "Installation cancelled."

If it does not exist — proceed to 4b.

4b: Copy files

1. Create the target directory: ~/.claude/skills/<skill-name>/
2. Copy all files from output/<skill-name>/ to ~/.claude/skills/<skill-name>/:
   • SKILL.md
   • references/ directory (if exists)
   • scripts/ directory (if exists)
   • README.md (if exists)
   • assets/ directory (if exists)

mkdir -p ~/.claude/skills/<skill-name>
cp -r output/<skill-name>/* ~/.claude/skills/<skill-name>/

Phase 5: Confirm

## Skill Installed

**[skill-name]** has been installed to `~/.claude/skills/[skill-name]/`.

Files installed:
- [list of files copied]

Restart Claude Code to pick up the new skill, then use it with:
- `/[skill-name] [example usage based on argument-hint]`

Rules

• Never install a skill that fails validation without explicit user approval
• Always show what will be installed before copying
• If the skill already exists at the target, warn the user and ask to overwrite or skip
• Do not remove the skill from output/ after installing — keep it as a local backup
