+# Stable Release Workflow for Kilo CLI
+# =====================================
+#
+# HOW TO RELEASE:
+# 1. Go to GitHub Actions → publish-stable
+# 2. Click "Run workflow"
+# 3. Enter the version (e.g., 1.0.0) - REQUIRED for stable releases
+# 4. Click "Run workflow"
+#
+# HOW USERS INSTALL:
+#   npm install -g @kilocode/cli
+#
+# REQUIRED GITHUB SECRETS:
+# - NPM_TOKEN: npm authentication token with publish access to @kilocode/cli
+#   (Get from: npmjs.com → Access Tokens → Generate New Token → Automation)
+#
+# WHAT THIS DOES:
+# - Runs the existing publish-start.ts script with OPENCODE_CHANNEL=latest
+# - Builds all platform binaries (Linux, macOS, Windows, x64, ARM64)
+# - Publishes to npm with @latest tag (default for npm install)
+# - Creates git tags and GitHub releases
+# - Includes npm provenance attestation for supply chain security
