+## What and why
+
+<!-- One bullet per change: what changed and why. The diff already shows how. One concern per PR. -->
+
+-
+
+## Linked issue
+
+<!-- Write "Fixes #N" only if this PR delivers everything the issue asks for, because merging closes the issue. Otherwise write "Part of #N" or "Related to #N". -->
+
+## Test run
+
+<!-- Paste the commands you ran and their pass/fail counts, for example "bun test tests/: 1204 pass, 0 fail". Name any check you skipped and why. A PR with no test run here will be closed. -->

+## Checklist
+
+- [ ] I ran `bun install --frozen-lockfile`, `bun tools/generate.mjs`, and `bun test tests/`, and committed the generator's output.
+- [ ] `bun tools/generate.mjs --check` exits 0.
+- [ ] I changed model defaults only in `plugins/pstack/models.json`, and every Pi model ID is in Pi's catalog for that provider.
+- [ ] If this changes skill behavior, it adds a `CHANGES.md` entry and bumps `VERSION`, or names the release PR that will.
+- [ ] If this touches `plugins/pstack/pi/`, `pi-tools.md`, `plugins/pstack/hooks/`, `copilot-tools.md`, or `setup-pstack`, I ran the runtime checks that [CONTRIBUTING.md](https://github.com/michael-denyer/pstack-claude/blob/main/CONTRIBUTING.md#before-you-open-a-pr) lists for those paths.
