From 88431defbaaee945bb4a2f42223d10b56646fc70 Mon Sep 17 00:00:00 2001 From: Emeriko Date: Sat, 13 Jun 2026 06:06:03 +0200 Subject: [PATCH] docs: replace em dashes with plain punctuation across prose Swap em dashes for commas/colons/periods in the README, skills, AGENTS.md and its five rule copies, examples, command files, and benchmark README. Rule copies stay in sync (same edit applied to all) and the invariant guard passes. Left untouched on purpose: the vendored caveman SKILL.md (verbatim third-party text), the dated benchmark writeups in results/ (historical records), and .js code comments.
