ScriptAnalyzer is missing a lot of warnings

Prerequisites

I have written a descriptive issue title.
I have searched all open and closed issues to ensure it has not already been reported.
I have read the troubleshooting guide.
I am sure this issue is with PowerShell Editor Services itself and does not reproduce in a standalone PowerShell instance, and is not an issue with my editor.
I have verified that I am using the latest version of PowerShell Editor Services.
If this is a security issue, I have read the security issue reporting guidance.

Summary

I've been using PSScriptAnalyzer (1.25.0) from the PowerShell command line on an individual file like:
Invoke-ScriptAnalyzer .\foo.ps1

I'm getting warnings for rules: PSAvoidShouldContinueWithoutForce, PSAvoidUsingInvokeExpression, PSReviewUnusedParameter, PSShouldProcess and PSUseSingularNouns

Now, I've been running PowerShellEditorServices LSP (latest version) in my editor on that same file but I'm not getting any of these warnings reported. And yes the LSP is working because it reported other types of errors/warnings normally.

My question is, is it possible to modify the default settings or rules included? Or is it a bug somewhere?

PowerShell Version

C:\Users\grolongo> $PSVersionTable

Editor Version

Emacs version: 30.2 (latest stable)

LSP client setup is really simple:
(use-package powershell :ensure t :demand t)

then to install the LSP server:
M-x powershell-install-langserver

Eglot connects successfully.

PowerShell Editor Services Version

ModuleVersion = '4.5.0'

Steps to Reproduce

create a ps1 file and write a simple function with a plural noun like Install-Programs
run PSScriptAnalyzer: Invoke-ScriptAnalyzer .\foo.ps1 -> PSUseSingularNouns warning reported
open the same file in your editor with LSP on -> no warning reported

My question is, is it possible to modify the default settings or rules included? Or is it a bug somewhere?

Yes it is possible and to my recollection, the default config in PSES is not the same as the default config running PSSA by itself. Why it was designed that way, I don't know. How to configure it over LSP in Emacs...I'd have to dig but I think you can find it in another issue.

I dug and couldn't find it. It's a matter of setting the server's PSSA config options via Eglot.

Thank you Andy,

I tried to change the rules tweaking the configuration files in
c:/Users/grolongo/AppData/Roaming/.emacs.d/.cache/powershell/PSScriptAnalyzer/1.25.0/
but that didn't work.

If I can manage to do that from Eglot that would be even better. I'll reply back if I can find the solution.

Alright, managed to find it with Eglot. So for reference, if someone wants to change what rules to apply or not for any project, do it like this (Emacs only):

Create a ps data file, call it PSScriptAnalyzerSettings.psd1 for example, and inside it add your rules:

@{
    Rules = @{
        PSUseSingularNouns = @{
            Enable = $true
        }
        PSShouldProcess = @{
            Enable = $false
        }
        PSAvoidShouldContinueWithoutForce = @{
            Enable = $true
        }
    }
}

Then in your init.el:

(setq-default eglot-workspace-configuration
                '(:powershell
                  (:scriptAnalysis
                   (:settingsPath "path/to/PSScriptAnalyzerSettings.psd1"))))

and voilà!

That's it! Good work.
