## What it does

The skill generates XML definitions for Salesforce Custom Settings in `force-app/main/default/objects/<Name>__c/<Name>__c.object-meta.xml`. Its primary role is enforcing the mandatory `<customSettingsType>` tag. Without this tag, the Salesforce CLI treats the component as a standard CustomObject and fails with invalid validation errors.

It creates metadata definitions only, not the record values themselves, because Salesforce treats setting values as data rather than metadata. When building trigger bypass switches or maintenance flags, the skill generates a hierarchy setting with a checkbox and deliberately skips Apex handlers.

Working with this skill requires the `sf` CLI version `2.136.8` or higher and API version `60.0`. It prevents invalid XML additions by omitting forbidden tags like `<pluralLabel>`, `<sharingModel>`, and `<nameField>`.

## Requirements
- Works with: Salesforce

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add forcedotcom/sf-skills --skill platform-custom-setting-generate -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/platform-custom-setting-generate/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/platform-custom-setting-generate/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add forcedotcom/sf-skills --skill platform-custom-setting-generate -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/platform-custom-setting-generate/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add forcedotcom/sf-skills --skill platform-custom-setting-generate -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/platform-custom-setting-generate/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install forcedotcom/sf-skills platform-custom-setting-generate
```

2. **Manually: put the files in place**
- File: `.github/skills/platform-custom-setting-generate/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add forcedotcom/sf-skills --skill platform-custom-setting-generate -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/forcedotcom/sf-skills --path skills/platform-custom-setting-generate
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/platform-custom-setting-generate/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add forcedotcom/sf-skills --skill platform-custom-setting-generate -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/forcedotcom/sf-skills/tree/HEAD/skills/platform-custom-setting-generate/SKILL.md

## When to use it
- generate Hierarchy or List Custom Setting metadata
- create trigger bypass flags for bulk data loading
- strip forbidden elements like pluralLabel from setting XML
- validate Custom Setting definitions against Metadata API rules

## Example prompts
- Create a hierarchy custom setting for trigger bypass flags
- Generate metadata for a List custom setting in force-app
- Validate the custom setting XML file and verify customSettingsType

# Salesforce Custom Setting Generator and Validator

## When to Use This Skill

Use this skill when you need to:

- Create a Hierarchy or List custom setting
- Generate custom setting metadata XML
- Add or validate fields on an existing custom setting
- Populate custom setting **values** (these are data, not metadata — see Section 6)
- Troubleshoot custom setting deployment errors

> **A trigger bypass / kill switch is a Custom Setting — not Apex and not a `__mdt`.** When the user wants a
> switch admins can flip to turn behavior on or off — "disable my Account triggers during a data load", a
> feature toggle, a maintenance-mode flag — generate **only** a hierarchy custom setting with a `Checkbox`
> field (e.g. `Disable_Triggers__c` / `Bypass__c`). Do **not** author the Apex trigger, handler, or test
> that reads it, and do **not** model it as a Custom Metadata Type: the per-profile/per-user override a
> bypass flag needs is exactly what a hierarchy custom setting gives you and a `__mdt` does not. The Apex
> that checks the flag is the developer's to write — this skill generates the setting only.

For authoritative Metadata API type, field, and enum details beyond this skill, use the `platform-metadata-api-context-get` skill.

## 1. Overview and Purpose

This document defines the mandatory constraints for generating Custom Setting metadata. A custom setting is
a `CustomObject` with `<customSettingsType>` set — it is **not** a distinct metadata type.
