# Validate Agent YAML

Validate Copilot Studio agent YAML files using the LanguageServerHost binary's full diagnostics — the same validation engine used by the VS Code Copilot Studio extension.

## Instructions

1. **Locate the agent workspace.** Find the directory containing `.mcs/conn.json`. If a specific file was requested, use the workspace that contains it.

2. **Run LSP-based validation**:
   ```bash
   node ${CLAUDE_SKILL_DIR}/../../scripts/manage-agent.bundle.js validate \
     --workspace "<path-to-agent-folder>" \
     --tenant-id "<tenantId>" \
     --environment-id "<envId>" \
