# /fusion · /auto-validate · /opinion — fuse two frontier models (AND, not OR).
# The HOST runs on the BUILDER model: raw (non-slash) input IS the builder agent.
#
# Two launch recipes, two tiers — everything else is a flag:
#
#   just fh-workhorse    cheap pair (sonnet-5 plans · terra builds + hosts) — use for testing
#   just fh-sota         frontier pair (fable-5 plans · sol builds + hosts) — the on-camera run
#
# Configuration flags (all optional, appendable to either recipe):
#   --architect <provider/id>              plans/fuses/validates
#   --builder <provider/id>                builds
#   --architect-thinking <level>           EVERY architect-family execution
#   --builder-thinking <level>             EVERY builder execution
#                                          (levels: off|minimal|low|medium|high|xhigh|max)
#   --architect-system-prompt <text|path>  override architect worker/fusion system prompt
#   --builder-system-prompt <text|path>    override builder system prompt
#   --max-validations <n>                  /auto-validate halt cap            default 5
#   --escalate-to-validator-count <n>      validator triage from Nth failure  default 3
#   --child-timeout <seconds>              kill any child agent after N sec   default 28800 = 8h (max 86400)
#
# e.g. just fh-workhorse --architect-thinking high --builder-system-prompt ./persona.md
#      just fh-sota --architect-thinking max --builder-thinking max

# Default prompts live in extensions/fusion-harness/{SYSTEM,USER}_PROMPT_*.md — edit to tune.
