What problem does it solve? Maintaining consistency across six consumer plugins that share the webtools-ui SDK requires repeated manual checks of manifests, HTML structure, MCP wiring, and agent configuration. This Skill centralizes those platform-wide validation and registry tasks so agents do not accidentally treat the shared SDK as a product runtime. ## Core Features & Use Cases - Harmonization CI: Run core gates, enhanced cross-consumer validation, and MCP/agent wiring checks via make targets and Python audit scripts. - Plugin contract management: Validate plugin.manifest.json files against the registry and sync registry snapshots across consumer repos. - Installer and registry operations: Use install scripts, the knowledge-registry, and the Tools Hub bootstrap for platform setup. - Use Case: After updating the shared chat-orb CSS, run the enhanced validation and plugin manifest checks to confirm all six consumers still conform to the platform contract. ## Quick Start Ask the agent to run the webtools-ui platform validation gates and check all consumer plugin manifests for contract compliance.
