+# This template wires Agent Skills (https://agentskills.io) into Plano so the
+# built-in Plano-Orchestrator can decide *per request* which skill(s) to attach
+# to the selected route.
+#
+# 1. Install skills locally:
+#      planoai skills add owner/pdf-processing
+#      planoai skills add owner/code-review
+#    Skills land under .plano/skills/<name>/SKILL.md.
+#
+# 2. (Required for project-scope skills) Mark the project trusted so its
+#    skills auto-load at startup:
+#      planoai skills trust
+#
+# 3. Reference the installed skills under `routing_preferences[].skills`.
+#    During the intent step Plano-Orchestrator receives both a <routes> and a
+#    <skills> XML block; it picks a route and zero or more skills, and the
+#    SKILL.md bodies of the chosen skills are injected into the upstream
+#    system prompt for that turn.
