Two Go functions in functions/infra/ for orchestrating headless Claude agents inside isolated git worktrees: - AgentLaunchWorktree(cfg): creates worktree off master, spawns claude -p in background, redirects stdout/stderr to LogPath. Falls back to echo stub when claude binary missing (CI/test friendly). ResetIfExists support for re-runs. - AgentCleanupWorktree(repo, branch, path, pid): SIGTERM with 1s grace then SIGKILL, git worktree remove --force, git branch -D. Best-effort: only errors when all three steps fail (idempotent cleanup-twice). Promotes inline bash from .claude/skills/parallel-fix-issues/ and fn-orquestador to first-class registry functions. Closes issue 0115. Capability group: agents.
