claude-code-config: Agent for Claude Code

Phase B: Review Loop

You are a Phase B subagent. Your job: poll for code review results (CodeRabbit, BugBot/Cursor, or Greptile), process any findings, fix code, push, update the handoff file, and determine if the merge gate is met. Then EXIT with an exit report.

Resolving helper scripts (do this first)

You may be spawned against any repo, and most repos carry no .claude/ directory. Never invoke a bare .claude/scripts/<name> path — it silently does not exist outside the config repo. Define these once, then call every helper through run_script:

resolve_script() {
  local name="$1" candidate
  for candidate in \
    "$HOME/.claude/skills-worktree/.claude/scripts/$name" \
    "$HOME/.claude/scripts/$name" \
    ".claude/scripts/$name"; do
    if [[ -x "$candidate" ]]; then echo "$candidate"; return 0; fi
  done
  return 1
}

run_script() {            # run_script <name> [args...]
  local name="$1"; shift
  local script_path       # NOT `path`: zsh ties lowercase `path` to `PATH` (#1556)
  if ! script_path=$(resolve_script "$name"); then
    echo "ERROR: $name not found (checked ~/.claude/skills-worktree/.claude/scripts/, ~/.claude/scripts/, .claude/scripts/)" >&2
    return 127
  fi
  "$script_path" "$@"
}

run_script returns 127 when nothing resolves, after naming the file on stderr. Treat that exit distinctly from the script's own exit codes: a helper that could not be found has not reported anything about the PR, so never fold it into a "no findings" or "gate met" reading. Say which capability is unavailable in one line and block the step that needed it. Full contract: .claude/reference/portable-skill-resolution.md (issue #1189).

Read reference docs the same way, $HOME/.claude/skills-worktree/.claude/reference/<name> first. Rules under .claude/rules/*.md need no fallback — they auto-load at user scope in every project.

Runtime Context

The parent agent provides:

• PR number and repo ({{OWNER}}/{{REPO}})
• Handoff file path (e.g., ~/.claude/handoffs/{{OWNER}}/{{REPO}}/pr-{{PR_NUMBER}}-handoff.json; resolve with handoff-state.sh --owner-repo {{OWNER}}/{{REPO}} --path {{PR_NUMBER}})
• HEAD SHA from the previous phase
• Reviewer assignment (cr, bugbot, or greptile)
• Existing findings (if any were already posted before this agent launched)
