Skill v1.0.1

version: "1.0.1" name: platform-report-generate description: "Use this skill when users need to create, generate, or validate Salesforce Lightning Report metadata. Trigger when users mention reports, creating reports, report metadata, .report-meta.xml files, tabular reports, summary reports, matrix reports, joined reports, report columns, report groupings, report filters, report charts, cross-filters, bucket fields, report formulas, or report time frame filters. Also use when users say things like 'create a report', 'generate a report', 'build a report on Accounts', 'add a chart to my report', or when they encounter deployment errors for .report-meta.xml files. Do NOT trigger for: creating or modifying Custom Report Type metadata (.reportType-meta.xml — use platform-custom-report-type-generate), creating dashboards, creating list views, running or viewing existing reports in the UI, or SOQL queries." metadata: version: "1.0" domains: ["Platform"] minApiVersion: "60.0" relatedSkills:

Overview

Lightning Reports define how Salesforce data is queried, grouped, filtered, and displayed. Each report is a single .report-meta.xml file placed under reports/<FolderName>/ within the project's source directory (check sfdx-project.json → packageDirectories[].path for the source root).

Critical Rules (Read First)

TOP DEPLOYMENT KILLERS — check these BEFORE generating any report:

1. Grouping fields in columns — Fields in <groupingsDown> or <groupingsAcross> must NEVER also appear in <columns>
2. Wrong column names — Column names are report-type-specific. ALWAYS call MCP tools to verify (see references/column-names.md)
3. Wrong scope — LeadList uses org, not organization
4. Filter column dot notation — Filter <column> values use FLAT names (INDUSTRY, TYPE) NOT dot notation (ACCOUNT.INDUSTRY is INVALID)
5. Multi-value picklist filters — Use ONE <criteriaItems> with comma-separated <value> (e.g., Technology,Financial Services). Do NOT split into multiple criteriaItems with booleanFilter

Rule 1: Format Determines Required Elements

Rule 2: Use Platform Column Names

Report metadata uses platform report column names, NOT raw API field names. ALWAYS call `get_metadata_type_sections` or `get_metadata_type_context` to confirm valid column names. See references/column-names.md for common mappings per report type.

Rule 3: Valid Report Type Required

<reportType> must be a standard API name (e.g., Opportunity, AccountList, CaseList, LeadList, AccountContactRole) or a deployed custom report type developer name.

Rule 4–5: Chart & Aggregates Require Summary/Matrix

Charts and <aggregateTypes> (Sum, Average, etc.) only work in Summary and Matrix reports.

Rule 6–8: Limits

• Max 3 cross-filters per report, each with up to 5 criteria items
• <filterLogic> must reference all filters sequentially (e.g., 1 AND (2 OR 3))
• Joined reports: 2–5 blocks, each block format must be Summary or Matrix (not Tabular)

Rule 9: Folder Structure

Reports must live inside a folder with a corresponding folder metadata file:

<sourceDir>/reports/<FolderName>/<ReportName>.report-meta.xml
<sourceDir>/reports/<FolderName>-meta.xml

Determine <sourceDir> from sfdx-project.json (commonly force-app/main/default, but this is configurable).

Rule 10–11: Date Columns & Scope

• Date columns use platform names (CLOSE_DATE, not CloseDate)
• LeadList scope is org; Opportunity/AccountList/CaseList use organization

Rule 12–13: Description & Groupings

• <description> max 255 characters
• Grouping fields must NOT appear in <columns> — automatic deployment failure

Rule 14: Folder Metadata Requires <sharedTo>

<?xml version="1.0" encoding="UTF-8"?>
<ReportFolder xmlns="http://soap.sforce.com/2006/04/metadata">
    <folderShares>
        <accessLevel>Manage</accessLevel>
        <sharedTo>AllInternalUsers</sharedTo>
        <sharedToType>Group</sharedToType>
    </folderShares>
    <name>My Report Folder</name>
</ReportFolder>

Rule 15: Valid Date Intervals Only

Use INTERVAL_CURRENT for "this quarter", INTERVAL_CURY for "this year", INTERVAL_LAST30 for last 30 days. Do NOT use INTERVAL_CURQ — it is not valid. See references/date-intervals.md for the full list.

Top-Level Elements

Filter Syntax

<filter>
    <criteriaItems>
        <column>STAGE_NAME</column>
        <operator>equals</operator>
        <value>Closed Won</value>
    </criteriaItems>
</filter>

Multi-value picklist: Use ONE criteriaItem with comma-separated values:

<criteriaItems>
    <column>INDUSTRY</column>
    <operator>equals</operator>
    <value>Technology,Financial Services</value>
</criteriaItems>

Common operators: equals, notEqual, lessThan, greaterThan, contains, startsWith, includes, excludes, isBlank, notBlank. Full list in references/filter-operations.md.

Generation Workflow

1. Gather Requirements — object, fields, groupings, filters, chart needs
2. Determine Format — no groupings → Tabular; row groupings → Summary; row + column → Matrix; multiple objects → Joined
3. Identify Column Names — call get_metadata_type_sections MCP tool to get valid platform column names for the report type
4. Author Metadata — start from closest example in examples/ and adapt
5. Create Folder — generate folder directory + <FolderName>-meta.xml with <folderShares>
6. Validate — run through references/verification-checklist.md
