user-invocable: true
tags: [regex, regexp, pattern, match, replace, test, validate]
capabilities:
  [regex_test, regex_replace, regex_explain, regex_library, regex_generate]
tools:
  - regex_test
  - regex_replace
  - regex_explain
  - regex_library
instructions: |
  Use this skill to work with regular expressions. Test patterns against text,
  perform find-and-replace, get explanations of complex regex, access a library
  of common patterns (email, URL, phone, IP, date, etc.), and extract matches from files.
examples:
  - input: "/regex-playground --test \"\\d{4}-\\d{2}-\\d{2}\" --text \"Today is 2026-02-17\""
    output: "1 match found: 2026-02-17 (position 9-19)"
  - input: '/regex-playground --replace "foo" --with "bar" --text "foo and foo"'
    output: "Result: bar and bar (2 replacements)"
  - input: "/regex-playground --library email"
    output: "Email pattern: ^[\\w.+-]+@[\\w-]+\\.[\\w.]+$"
  - input: "/regex-playground --explain \"^(?=.*[A-Z])(?=.*\\d).{8,}$\""
    output: "Password validation: at least 8 chars, 1 uppercase, 1 digit"
