Check Emacs config for org-ql and test emacs --batch queries to list projects/targets; report usefulness.
Created /home/ben/.emacs.d/org-agent-init.el for batch org-ql queries; added skills/org-ql.md with usage and examples (projects, tags, overdue).
Confirmed org-ql is installed (init.el loads use-package org-ql). In batch, org-ql works after (require 'package) (package-initialize) (require 'org-ql). Ran org-ql-select on org-agenda-files with (todo "PROJ") and got project list output.
