# opencode-start.sh — Start OpenCode with or without oh-my-openagent
# =============================================================================
#
# PURPOSE:
#   Wrapper script that starts the OpenCode server, optionally injecting the
#   oh-my-openagent plugin at runtime via OPENCODE_CONFIG_CONTENT.
#   No files are mutated — the base opencode.json stays clean.
#
# USAGE:
#   ./opencode-start.sh          — Start without omoa (vanilla)
#   ./opencode-start.sh --omoa   — Start with omoa enabled
#
# HOW IT WORKS:
#   - Reads ~/.config/opencode/opencode.json
#   - If --omoa flag is set, uses python3 to add oh-my-openagent@latest to the
#     plugin array and sets OPENCODE_CONFIG_CONTENT with the modified JSON
#   - If --omoa is not set, starts with the clean config file
#   - OPENCODE_CONFIG_CONTENT has higher precedence than the config file,
#     so the plugin is only active for that process
#
