Last year a few of us at the Perl Toolchain Summit got together to trade command-line tips. Iwrote up the notes. This year there was some demand for a repeat, so we continued the tradition. Hopefully you find some helpful tips.

Full disclosure: I don’t use AI to write the content of my blog posts, but in this case I did get an assist from Claude, particularly in summarizing notes and adding project links. Since this is meant to be a cheat sheet rather than a piece of creative writing, I’m ok with using AI as a tool to help get the job done.

The initial post featured male wrestlers, so I’m hoping this year’s photo provides a much needed counterbalance.# Leo’s Picks# superpowers

An agentic skills framework and software-development methodology for coding agents like Claude Code. Rather than diving straight into writing code, it pushes the agent to tease a spec out of the conversation, get your sign-off, and then work through an implementation plan with an emphasis on test-driven development.

Olaf’s note: superpowers deserves its own series of posts. I rely on this quite heavily for all sorts of daily tasks.# nono

A capability-based sandbox for AI agents and other untrusted processes. It uses kernel-level primitives — Landlock on Linux, Seatbelt on macOS — to enforce a default-deny policy, so a process starts with no file, network, or command access until you explicitly grant it.

Olaf’s note: I use nono every day, thanks to Leo having pointed it out shortly before we got together for the summit. Now I spend a lot less time building Docker containers. 😅# Shawn’s Picks# eza

A modern replacement for ls with colourful, human-friendly output and git integration for directories. Claude’s note: eza was also a pick inlast year’s throwdown.# fx

A terminal-based JSON viewer and processo…
