Create the basic plugin structure for contract-validator: Plugin structure: - plugins/contract-validator/.claude-plugin/plugin.json - plugins/contract-validator/.mcp.json - plugins/contract-validator/mcp-servers/contract-validator -> symlink MCP server scaffolding: - mcp-servers/contract-validator/mcp_server/server.py (7 placeholder tools) - mcp-servers/contract-validator/pyproject.toml - mcp-servers/contract-validator/requirements.txt - Virtual environment with mcp>=0.9.0 Tools defined (placeholders): - parse_plugin_interface - parse_claude_md_agents - validate_compatibility - validate_agent_refs - validate_data_flow - generate_compatibility_report - list_issues Sprint: Sprint 2 - contract-validator Plugin Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
