 This port applies the Cursor → Claude Code substitutions in skill bodies. Earlier drafts left them flagged; this revision resolves them. A later pass added a Codex build that shares the same skills; see [Codex port](#codex-port) below.
 
+## 1.4.1 syncs to Cursor pstack 0.15.1
+
+Open Pstack 1.4.1 tracks Cursor pstack 0.15.1 at `f8abeddd1862dc73704e3d719dd73df0d51b8c71`. Poteto-mode now requires each claim to include its evidence or a measured, inferred, or guess label in the same sentence. Agents also run any check they can run themselves instead of handing that check to the user. No playbook, model, runtime, or dependency changed.

 ## 1.4.0 syncs to Cursor pstack 0.15.0
 
 Open Pstack tracks Cursor pstack 0.15.0 at `71ed0d1076fec562c1b74ee353121a8d00f75382`. The shared catalog contains 54 skills, including 23 principles. This sync imports the skill density and punctuation passes, the 361,140-byte logo, and the verbatim upstream README. How, Why, and Teach take the shorter explanation guidance. Reflect runs only on explicit invocation. Poteto-mode no longer requires reading the whole principle index as the first todo, but still requires reading any applied leaf and citing it truthfully. Unslop adds the mannered-prose and over-compression rules, preserving stable rule numbers. Technical-writing proposes new abstract-metaphor offenders and replacements without editing Unslop automatically.

 Original by Lauren Tan. This distribution builds on Michael Denyer's [pstack-claude](https://github.com/michael-denyer/pstack-claude) port and retains its history and MIT attribution. It imports seven MIT-licensed skills from [cursor-team-kit](https://github.com/cursor/plugins/tree/main/cursor-team-kit): `deslop`, `thermo-nuclear-code-quality-review`, `make-pr-easy-to-review`, `fix-ci`, `fix-merge-conflicts`, `get-pr-comments`, `what-did-i-get-done`.

 - **Terse is not an excuse to drop content.** Every item the playbook's reply names stays. Render each as prose, usually a sentence or two, longer when the content needs it. No section headers, and no item expanded into its own block.
 - **Frame impact for the consumer and the maintainer.** Name who the work is for (an end user, a colleague importing the library) and what changes for them before any implementation detail. Then what the next engineer who owns this code inherits. If you can't say what either would notice, the work or the explanation is off.
 - **Never fabricate a link, citation, or transcript reference.** Link only artifacts you produced or read this session.
+- **Every claim carries its evidence or its label in the same sentence.** Measured, inferred, or guess. A prediction or an unseen cause is a guess. Never hand the human a check you could run.
 
 Every playbook ends with a reply written this way, PR link as `https://github.com/<owner>/<repo>/pull/<number>`. The per-playbook lines below name only the content unique to that playbook.
