Tool Creator Workflow

1. Ask for the tool's file name (e.g., web_search_tool).
2. Read the template: cat .claude/skills/careercopilot-tool-creator/templates/tool.py.tpl
3. Replace placeholders like {{TOOL_NAME}} with the file name.
4. Write the new file to src/tools/{{TOOL_NAME}}.py.
5. Advise the user to now add the tool to src/tools/__init__.py and to the agent file.
