Curated by Skill Harbor: a modernization guide that makes Muse write and review Perl 5.36+ the way current Perl developers do, not the way Perl looked in 2005. It starts with the single use v5.36 pragma that replaces the old strict/warnings boilerplate and enables signatures, then covers subroutine signatures with defaults and slurpy parameters, scalar versus list context, postfix dereferencing for readable nested structures, and the infix isa operator. Error handling moves from eval/die to Try::Tiny and the native try/catch of 5.40+. Modern OO prefers Moo with typed attributes and roles over blessed hashrefs, with the native class keyword of 5.38+ as the coming standard. Regular expressions get named captures with the /x flag and precompiled qr// patterns. File I/O uses three-argument open with autodie and Path::Tiny, module organization follows a standard lib/bin/t layout with Exporter, and the tooling section covers perltidy, perlcritic and cpanfile with carton. A legacy-to-modern quick reference table and an anti-pattern list (two-arg open, string eval, no strict refs) close the skill. By @affaan-m, listed here with credit to its creator. From the affaan-m/ECC repository (MIT). Honest caveats: the modern features need Perl 5.36 or newer, check your production version before adopting; the native class keyword is still experimental in some versions; it will not make legacy CPAN code disappear. Skill Harbor never reviews the code, review it yourself before use.

Install
Copy the install package below, then paste it into MuseThe install prompt below already includes the vetting steps: your agent follows the community checklist before installing anything with executable code. Want more?
Use "Modern Perl Patterns" with your Muse. Prerequisites: none to install. Pure guidance; a Perl project helps. 1. Open the skill: https://github.com/affaan-m/ECC/blob/main/skills/perl-patterns/SKILL.md and copy the full SKILL.md text. 2. Paste it into a chat with Muse and add: "Modernize this legacy Perl to 5.36+ idioms: [paste code]." 3. Ask follow-ups like "convert this blessed hashref class to Moo" or "find the two-arg opens and string evals in this file." Tip: check your Perl version first; the patterns assume 5.36+. Safety: a skill is plain-text instructions; it runs nothing by itself. Review generated commands before running them, especially anything touching production.

Questions
How do I install a build?
Every product page includes a copy-paste install prompt. Paste it into your Muse and it sets the build up for you — no manual configuration.
Where does my money go?
Straight to the seller. Skill Harbor never processes payments: checkout happens on the seller’s own page, usually Stripe.
What does the ✓ next to a creator’s name mean?
It means we confirmed the identity of the person behind the listing. It says nothing about the code itself — always check a build before installing it.
