# platform-custom-report-type-generate

Guides the agent through authoring and validating Salesforce Custom Report Type metadata: base object, joins, exposed fields. Handy when a .reportType-meta.xml deploy fails.

## What it does

The skill gives the agent a rulebook for `.reportType-meta.xml` files. One CRT is one file, and the file basename becomes the report type's developer name. It spells out the required elements: `<fullName>`, `<label>`, `<baseObject>`, `<deployed>`, plus `<join>` and `<sections>` with their columns.

A separate block covers the critical rules. If `<fullName>` is present, it has to match the file name exactly — same characters, same casing, same underscores. Each join hinges on `<outerJoin>`: `false` keeps only records that have children, `true` keeps them all. A join chain holds at most four objects, and an inner join after an outer one is not allowed. Fields are referenced by API name, never by label.

The skill targets authoring, not reporting. It stays away from running, editing or filtering existing reports, and from folders, dashboards and list views. API version 51.0 or higher is required, otherwise some elements will fail validation at deploy time.

## Requirements
- Works with: Salesforce

## Install

### Claude Code (native platform)

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

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

### Codex

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

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

### Cursor

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

2. **Manually: put the files in place**
- File: `.cursor/skills/platform-custom-report-type-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-report-type-generate
```

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

### Gemini CLI

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

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

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add forcedotcom/sf-skills --skill platform-custom-report-type-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-report-type-generate/SKILL.md

## When to use it
- build a CRT across custom objects and their relationships
- pick inner or outer join for a chain of objects
- check that `<fullName>` matches the file name
- debug a `.reportType-meta.xml` deployment error
- curate the field set shown in report builder

## Example prompts
- Create a Custom Report Type for Account and Project__c, fields from both, outer join
- Check my `AccountsWithProjects.reportType-meta.xml` — why does the deploy fail?
- Add a Contact join via `Contacts` to this CRT, no inner join after an outer one

## Specification

# Salesforce Custom Report Type Metadata Knowledge

## Overview
Custom Report Types (CRTs) define the **data framework** for Salesforce reports. They specify a primary object, up to 3 related objects, the relationship (join) between them, and which fields are available in the report builder.

## Purpose
- Enable reporting across custom objects and custom relationships not covered by standard report types
- Curate a focused set of fields for report builders (including fields reached via lookup)
- Control inner/outer join behavior to include or exclude primary records without related records

## Configuration

**File extension:** `.reportType-meta.xml`. The file basename is the report type's developer name (e.g. `AccountsWithProjects.reportType-meta.xml`). Each CRT is a single file, not nested under an object folder.

### Key Elements

Top-level `<ReportType>` children:

| Element | Required | Notes |
|---------|----------|-------|
| `<fullName>` | Yes | API identifier; must match the file name. Letters, numbers, underscores; must begin with a letter; no spaces; no trailing underscore; no consecutive underscores |
| `<label>` | Yes | Human-friendly name shown in the report type picker |
| `<description>` | Recommended | State the business "why" — who uses this and what they learn |
| `<baseObject>` | Yes | API name of the primary object (e.g. `Account`, `Project__c`). Cannot be changed after initial creation. All objects, including custom and external, are supported (external objects from API 38.0+) |
| `<category>` | Recommended | Report builder category — see `references/category-values.md` |
```
