# Agent skills from upstream and the /pr template

Matt Pocock's skills and pstack come from their upstream sources through the official installer, /pr joins the skills, and pull requests open with its Summary, Evidence and Merge Danger sections.

Matt Pocock's skills and pstack are installed again from their sources with the official `skills` installer, so `skills-lock.json` matches what upstream ships. `pr` is new from Matt Pocock. `design-an-interface` and `resolving-merge-conflicts` are gone because upstream deleted them, and `writing-great-skills` is gone because upstream renamed it to `writing-for-agents`, which the repo already had. `domain-modeling` keeps this repo's ADR header rules and was not reinstalled.

pstack adds `correct`, `in-your-own-words`, `ketchup`, `principle-attack-the-premise`, `principle-explain-the-number` and `principle-test-behavior-not-implementation`, and seven pstack skills follow upstream edits. pstack's `teach` and `tdd` stay out, so the names keep pointing at Matt Pocock's skills.

A new pull request opens with the `/pr` sections: Summary (a diff sketch, file tree or pseudocode, no Mermaid), Evidence (before and after) and Merge Danger (one-way or two-way door, blast radius). The checks list below them is unchanged. The template says that a merge to `main` deploys to production and that migrations, RLS changes, secret or env changes and feature removals are one-way doors. Skills that name `GLOSSARY.md` read this repo's `CONTEXT.md`.
