How to choose
Prioritize local execution for privacy and zero-latency loops when building agents. Check tool-unlimited or goal-spec features if your workflows need many skills without context limits. Test staging and state-management tools early to catch multi-agent coordination issues. Avoid pure monitors or security scanners unless you already have a core harness in place.
