deep-research

Answer a broad, open-ended, or multi-part question by iteratively searching MFS-indexed sources, following up on gaps, and synthesizing a cited report — the same "reason and search over private data" job zilliztech/deep-searcher does, but as a skill on top of mfs-find instead of a standalone framework. Use when the user asks for a report, a comprehensive/synthesized answer, a "what do we know about X across everything we have", or a question that can't be answered from a single search hit. Trigger phrases include "write a report on X", "deep-dive into X using our data", "research X across all our sources", "give me a comprehensive answer on X with citations", "synthesize what we know about X". Do NOT use for a single fact lookup or a targeted question with an obvious one-hit answer — use mfs-find directly for that; this skill is for genuinely broad, multi-angle asks. Requires mfs-find for the underlying search/read mechanics.
