16 agent skills worth installing

01 / THE IDEA

What a skill actually is

A recipe card the agent reaches for when the task matches. Without them you re-explain the same workflow every session, output quality tracks whatever mood the model is in, and anything multi-step drifts. With them the steps get written once and reused everywhere.

04 / THE ORDER

Install order from a standing start

The author’s closing line is the one to keep: do not collect skills like stickers. Install the ones that remove a pain you can feel this week. A small set you actually trigger beats a junk drawer.

05 / SECURITY

Security rules that carry over

Point offensive security skills only at systems you own or are authorised to test.
Give any autonomous browser agent its own profile. Never your main session.
Read install scripts before piping them into a shell.
Keep secrets out of prompts and out of skill logs.
Prefer local-first tools whenever the data is sensitive.
