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).

When This Skill Owns the Task

Use dx-code-analyzer-custom-rule-create when the work involves:

Creating a new custom rule for Code Analyzer (any engine)

Enforcing team-specific coding standards via static analysis

Banning specific patterns (System.debug, hardcoded IDs, TODOs)

Writing XPath expressions for PMD rules (Apex or metadata XML)

Writing regex patterns for the Regex engine

Setting up custom ESLint rules/plugins for LWC/JavaScript

Enforcing metadata governance (API versions, field descriptions, dangerous permissions)

Overriding built-in rule thresholds (CyclomaticComplexity, ExcessiveParameterList, etc.)

Organizing multiple rules into shared rulesets

Iterating on a custom rule that isn't matching correctly
