Quoting OpenAI Codex CLI
How to use a skill (progressive disclosure):
- After deciding to use a skill, open its
SKILL.md. Read only enough to follow the workflow.- If
SKILL.mdpoints to extra folders such asreferences/, load only the specific files needed for the request; don't bulk-load everything.- If
scripts/exist, prefer running or patching them instead of retyping large code blocks.- If
assets/or templates exist, reuse them instead of recreating from scratch.Description as trigger: The YAML
descriptioninSKILL.mdis the primary trigger signal; rely on it to decide applicability. If unsure, ask a brief clarification before proceeding.

“Eating the right foods in the proper quantities, 16th-century Britons believed, balanced mind and soul. So in Shakespeare’s plays, roasts, ales, and pies are not props, but clues to characters’ souls, moods, and motivations.”
This Is Why Everyone Is a DJ Now
I guess this is as good an explanation of contemporary culture as anything.
Hungover from a world that told us we could be anything, we decided to be DJs. We don’t create our own music. We curate playlists, recirculating songs that will make people think we’re cool. And we do this through the labels we wear, the books we read, the people we hang out with, and the opinions we parrot. The DJ figure, ruled by the same logic, is just another celebration of self.

OpenAI Releases GPT-5.2
OpenAI:
In ChatGPT, GPT‑5.2 Instant, Thinking, and Pro will begin rolling out today, starting with paid plans. In the API, they are available now to all developers.

5.1 was released just one month ago, but 5.2 delivers a slew of measurable improvements across the board. Where 5.1 was seemingly more about the feel of responses, the personality, 5.2 was clearly focused on tangible and benchmarkable gains.
