# Per-agent skill scoping. Skills are loaded on-demand by opencode: only a skill's one-line
# `description` ever appears in an agent's <available_skills> list, and the full SKILL.md body
# (curl/API how-to) is loaded ONLY when the agent calls the `skill` tool — it is never in any
# system prompt. To also hide the summary from agents that shouldn't use a skill, we deny all
# skills by default and allow only the ones in this agent's registry list (passed via $SKILLS).
# A denied skill is hidden entirely (name + description omitted), so e.g. @junior never sees
# gitea-api at all; it just knows from the roster that @senior/@lead can, and asks them.
