There's no easy way to see what your coding agents have actually installed — skills, subagents, commands, plugins, MCP servers, hooks — or which sessions are still alive vs. safe to delete.
Large Language Models (LLMs) achieve strong performance on reasoning tasks, but whether this reflects faithful logical inference or heuristic approximation remains unclear. We study this question in legal entailment by comparing three para…
