Install specialist modes from GitHub.

user-invocable: false description: Handles specialist mode installation by downloading from the agency-agents GitHub repository. Always confirms with user before installing. allowed-tools: [Read, Write, Bash, WebFetch, Glob, AskUserQuestion]

Instructions

When called with an agent to install, follow this flow.

Pre-installation Checks

1. Conflict detection: Check if an agent with the same name already exists:

   Glob: .claude/agents/{agent-id}.md
   Glob: ~/.claude/agents/{agent-id}.md
   

2. If already installed, inform the user and ask if they want to update/overwrite.
3. Always confirm with the user before proceeding with installation.

Installation

From agency-agents repository (primary)

1. Download the agent file from GitHub:

   WebFetch: https://raw.githubusercontent.com/msitarzewski/agency-agents/main/{path}
   

   Where {path} is the full path (e.g., engineering/engineering-frontend-developer.md)

2. Determine install location:

   • Project local (default): .claude/agents/{agent-id}.md
   • Global (if user requests): ~/.claude/agents/{agent-id}.md
   • Ask the user which location they prefer.

3. Create the directory if needed:

   mkdir -p .claude/agents
   

4. Write the downloaded content:

   Write: .claude/agents/{agent-id}.md
   

5. Add include reference to CLAUDE.md:

   • Read existing CLAUDE.md (or create if absent)
   • Add @agents/{agent-id}.md as an include line if not already present
   • This ensures Claude Code loads the specialist mode automatically

From other GitHub source

1. Confirm with the user.
2. Download via WebFetch from the raw GitHub URL.
3. Save to .claude/agents/{agent-id}.md
4. Add include reference to CLAUDE.md.

Post-installation Verification

After installation, verify:

1. The .md file exists at the expected path
2. The file is valid (non-empty, contains expected content)
3. The CLAUDE.md include reference exists
4. Report success or failure to the user

Output

Provide a clear summary:

• What was installed and its specialty
• Where it was installed (project local or global)
• The include reference added to CLAUDE.md

Language Rules

• NEVER use "에이전트", "agent", "persona" when talking to the user
• Use "전문가 모드", "전문 지원", "specialist mode" instead
