Merge Open PRs and Close Associated Issues

Merge open pull requests and automatically close any issues they reference via "Fixes #N".

Usage

• /merge-prs — merge ALL open PRs
• /merge-prs 123 456 789 — merge specific PR numbers

Steps

1. List open PRs (or use the provided numbers).
2. Merge each PR with --merge strategy.
3. For any that fail with merge conflicts, rebase on master and retry.
4. Extract "Fixes #N" references from each merged PR body.
5. Close the associated issues.
6. Report results.

Implementation

# Get PR list — either from args or all open
if [ -n "$ARGS" ]; then
  PRS="$ARGS"
else
  PRS=$(gh pr list --state open --json number -q '.[].number' | sort -n)
fi

if [ -z "$PRS" ]; then
  echo "No open PRs to merge."
  exit 0
fi
