install-opencode.sh

#!/usr/bin/env bash
# install-opencode.sh — export this marketplace's subagents + hooks to OpenCode
# format and install them additively into an OpenCode config directory.
#
# Runs export-opencode.sh into a disposable temp dir, then copies agents/,
# plugins/ (generated hook plugins), and hook-scripts/ into <target>. The copy
# is ADDITIVE: the user's own agents/plugins under <target> are preserved
# (no rm -rf of the target trees).
#
# SKILLS ARE NOT INSTALLED (#2094). They reach OpenCode through the adapter,
# which configure-opencode.sh wires into opencode.json — see
# adapters/opencode/ and docs/opencode-export.md.
