# scripts/tier2/setup_tier2_clone_directives.ps1
<#
.SYNOPSIS
  Directive-based alternative to setup_tier2_clone.ps1.
.DESCRIPTION
  Same bootstrap as setup_tier2_clone.ps1, but promotes the directive-based
  agent prompt (tier2-autonomous.warm.md) into the clone's
  .opencode/agents/tier2-autonomous.md slot. The agent then warms via a
  single manual-slop_aggregate_directives MCP call against
  conductor/directives/presets/current_baseline.md instead of ingesting the
  bulk-markdown prompt verbatim.

  The original tier2-autonomous.md is left untouched in the main repo (per
  the warm_md_duplicates_not_in_place directive: originals are the rollback
  target; .warm.md is the experimental layer). This script is the promotion
  step: it copies .warm.md into the clone's active agent slot.

  Idempotent: re-running updates templates and re-fetches, but does not
  destroy existing feature branches in the clone.
