Research FAQ
How do I install every Research skill at once?
Run curl -fsSL https://codexskills.dev/install.sh | sh -s -- --category research to put all 15 in ~/.agents/skills/, or add --project to install them into the current repository's .agents/skills/. You can also download the category zip and unpack it yourself.
Does installing 15 skills slow Codex down?
Hardly. At startup Codex sees only each skill's name and description, a few dozen words apiece, and reads a full SKILL.md only when a task needs it. Install the whole category if the work fits; unused skills cost almost nothing.
Which Research skill should I start with?
Start with Deep Research, Benchmark Comparisons, Citation Management. They cover the requests that come up most in this category. Mention one with $deep-research to try it.
