Generates, explains, and tests regular expression patterns. Builds patterns from positive and negative examples, breaks down each component with a readable explanation table, generates edge-case test suites, and provides usage examples in Python and JavaScript. Triggers on: "regex for", "regular expression", "pattern for", "match strings like", "extract from", "build regex", "create pattern", "explain this regex", "what does this regex do", "regex to match", "parse with regex", "validate format". Use this skill when building, explaining, or testing a regular expression pattern.
Decision framework for choosing between regex and LLM when parsing structured text — start with regex, add LLM only for low-confidence edge cases.
Build, test, and explain regular expressions against sample text or files using CLI tools (rg, python) and specific regex flavors. Use when asked to craft, debug, or validate regexes or search patterns.
Regular expression expert for crafting, debugging, and explaining patterns
Debug regex patterns with visual breakdowns, plain English explanations, test case generation, and flavor conversion. Use when user needs help with regular expressions or pattern matching.
Guidance for generating legal chess moves using only regex pattern matching and substitution. This skill applies when implementing chess move generators constrained to regex-only solutions, FEN notation parsing/manipulation, or similar pattern-matching-based board game logic. Use this skill for tasks requiring regex-based state transformations on structured string representations.
Use this skill when writing regular expressions, debugging pattern matching, optimizing regex performance, or implementing text validation. Triggers on regex, regular expressions, pattern matching, lookahead, lookbehind, named groups, capture groups, backreferences, and any task requiring text pattern matching.
Create custom Code Analyzer rules for Regex (pattern matching), PMD (XPath/AST for Apex and metadata XML), and ESLint (LWC/JavaScript/TypeScript). Use when users want to enforce coding standards, ban patterns, detect hardcoded values, govern metadata, or add rules not in the built-in set. TRIGGER when: user says 'create a rule', 'ban System.debug', 'enforce naming convention', 'detect hardcoded IDs', 'custom rule', 'xpath rule', 'regex rule', 'add a PMD rule', 'enforce a policy', 'create a check for', 'flag this pattern', 'make a rule that catches', 'metadata rule', 'check permissions', 'enforce API version', 'eslint rule', 'lwc rule', 'override rule threshold', 'customize complexity', or describes a pattern to enforce. DO NOT TRIGGER when: user wants to run a scan (use dx-code-analyzer-run), configure engines (use dx-code-analyzer-configure), or explain existing rules (use dx-code-analyzer-run).
Search file contents using regex patterns with ripgrep or grep. Use when: finding code, text patterns, or content across files.
Assess construction data quality using completeness, accuracy, consistency, timeliness, and validity metrics. Automated validation with regex patterns, thresholds, and reporting.
Runs tilth CLI for structural code navigation — reads files with smart outlining, searches symbols/text/regex, finds files by glob, and maps codebases. Use instead of read/grep/find for all source code exploration.
Control LLM output with regex and grammars, guarantee valid JSON/XML/code generation, enforce structured formats, and build multi-step workflows with Guidance - Microsoft Research's constrained generation framework
