Automation summary

• root_cause: In managePermissions tool schema, password (and username) were declared as z.string().optional() without any description indicating they are required for the createUser action. The runtime code correctly validates both parameters, but the model only sees the schema — which marks them optional with no hint about action-specific requirements. This caused the model to omit password when calling createUser, resulting in the API error "缺少必填参数 username 和 password".
• changes: Added .describe() to both username and password fields in the managePermissions tool's inputSchema at mcp/src/tools/permissions.ts:595-596, explicitly stating they are required for action=createUser. This is a Layer 1 (cheapest) fix — the schema still allows these fields to be optional (since they ARE optional for other actions like updateUser), but now the model is informed via the description that createUser requires them.
• validation: TypeScript compilation passes (tsc --noEmit), all 3 required skill quality tests pass (build-skills-repo, build-compat-config, skill-quality-standards).
• follow_up: None. The fix is minimal and targeted — only the two parameter
