+# Publishes the `pilotprotocol-mcp` npm package (the Pilot Protocol MCP server,
+# source at pilot-protocol/pilot-mcp) using THIS repo's NPM_TOKEN.
+#
+# Why it lives here and not in pilot-protocol/pilot-mcp: the npm automation
+# token with publish rights on the `pilotprotocol*` packages is a secret on
+# sdk-node, and secret values can't be copied to another repo. So the pilot-mcp
+# release is driven from sdk-node, which holds the token.
+#
+# Manual, on-demand (workflow_dispatch). Checks out the pilot-mcp repo at the
+# requested ref, sanity-checks the server, and publishes. No --provenance:
+# provenance attests the *workflow* repo, which would mismatch pilot-mcp's
+# package.json repository field.
