Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install python-313-features

With no option, the skill goes to ~/.agents/skills/; add --agent claude-code (or codex, cursor…) to target an agent.

First time: connect the CLI with

npx --yes palatekit@latest login

The agent applies Python 3.12 and 3.13 syntax: pattern matching, type parameters, exception groups and the walrus operator. It explains free-threaded mode and the experimental JIT and points out what still needs testing.
