- elasticsearch-search-relevanceelastic/agent-skillsImprove Elasticsearch search relevance for content and catalog indices: pin or promote results with query rules (correct rule type, criteria, and rule-query wiring) and tune organic ranking with multi_match, field boosts, and analysis grounded in the index mapping. Use when search results rank poorly, a specific document must appear first for a query, or the user asks to tune full-text matching — not for ES|QL analytics, index ingest, or cluster health.OfficialDataNo warnings★ 603↓ —Also in 1 other repo

- delegating-workmvschwarz/openrigUse when you have a task and must decide WHO does it — yourself, a spawned subagent, or another agent in the topology that already holds the context — or how to brief the agent you hand it to, which depends on the model it runs. The rule: how much would a blank slate have to read in to do this correctly? A lot → route to a context-holding agent; a little → subagent; unsure → a real agent or yourself. NOT the mechanics of fanning out (that's dispatching-parallel-agents / subagent-driven-development) — this is the who/whether decision, and the failure mode that makes teams abandon subagents. Also use it to decide how far to trust a delegated result.ProductivityNo warnings★ 8.3K↓ —
