rose-ash/scripts/sx-fix-up.sh

#!/usr/bin/env bash
# sx-fix-up.sh — spin up ONE claude fix-loop in tmux, driven by an agentic-sx
# branch in the rose-ash/sx-review forge (git-sx / gitea-sx / agentic-sx).
#
# This tests the git→gitea→agentic→tmux wiring: the forge holds the agent
# branch + briefing; this launcher READS that briefing from the forge (proving
# the forge drives the session), then materialises a git worktree and a tmux
# window running claude on the corresponding real branch.
#
# Usage: ./scripts/sx-fix-up.sh <forge-agent> <briefing.md> [interval]
#   forge-agent   agentic-sx agent branch in the forge, e.g. ws-W14
#   briefing.md   file under plans/agent-briefings/ with the detailed work plan
#   interval      optional /loop interval (e.g. 15m); omit for self-paced
#
# Example: ./scripts/sx-fix-up.sh ws-W14 sx-gate-loop.md
#
# The real code branch is loops/sx-<slug> in worktree
# /root/rose-ash-loops/sx-<slug>. Commits are LOCAL by default — the briefing
# decides whether to push. Watch: tmux a -t sx-fix ; stop: ./scripts/sx-fix-down.sh
