Dx Code Analyzer Custom Rule Create

This is the rule authoring companion to the Code Analyzer suite. It walks you through creating custom rules when the built-in set doesn't cover your org's patterns: banning System.debug, catching hardcoded IDs, enforcing metadata standards, or writing XPath queries against the Apex AST. The skill is opinionated about process (always dump the AST before writing XPath, never hand-edit the YAML after the scripts run) because the failure modes are specific and painful. It handles regex rules, PMD rules for Apex and metadata XML, and ESLint setup for LWC. If you're enforcing team-specific guardrails beyond what ships with Code Analyzer, this is the one that gets you there without trial-and-error escaping hell.

dx-code-analyzer-custom-rule-create: Custom Code Analyzer Rule Authoring

Ecosystem: This skill is part of a 3-skill Code Analyzer suite — dx-code-analyzer-run (scans & results) · dx-code-analyzer-configure (setup, config, CI/CD) · dx-code-analyzer-custom-rule-create (custom rule authoring).

Use this skill when the user needs to create a custom rule that enforces a pattern not covered by Code Analyzer's built-in rules. Supports Regex engine (text pattern matching) and PMD engine (structural XPath queries against the AST).
