"""Seed default agent templates into the database on startup.

Templates come from two sources, merged at seed time:

1. Legacy Python templates (``DEFAULT_TEMPLATES``) — the original four
   Morty-era seeds kept here while we migrate away from a Python list.
2. Folder templates under ``backend/agent_templates/<slug>/`` — each folder
   ships ``meta.yaml`` (structured fields) + ``soul.md`` (soul_template) +
   ``bootstrap.md`` (bootstrap_content).

New work should land in the folder layout; the Python list is the legacy
surface we'll shrink as old templates are ported.

# Each founding prompt is a one-shot system instruction the backend injects

# mechanics (prompts, files, "bootstrap") to the user — just play it out.
# The flow is always: warm greeting → exactly one targeted question → as
# soon as the user answers, immediately start a concrete role-specific demo
# task inline. The goal is to show value in the first message exchange,
# not to schmooze.
