+description: Search and explain accepted GEWU knowledge within an explicit project scope, preserving citations, freshness and uncertainty in a bounded answer.
+---
+# Query accepted knowledge
+
+Read the pack's [evidence](../../protocols/EVIDENCE.md) and [scope](../../protocols/SCOPE.md) protocols, then use the [query pipeline](../../pipelines/query.md). Consult [contributions](../../protocols/CONTRIBUTIONS.md) for connection/availability rules; this skill performs no knowledge writes.
+
+Establish the question, scope and response budget. Use supported search/read tools and inspect the sources behind the strongest results. Preserve complete citation groups and required warnings. Widen scope only through an explicit request consistent with the user's task.
+
+Separate accepted relationships from suggestions and distinguish disagreement from missing evidence. Answer with relevant conditions, as-of dates and source references near the claim. If retrieval is degraded, index-lagged or insufficient, state the observed limitation. Do not present a local draft, model recollection or unavailable service as an accepted GEWU result.
+
+The result is a cited answer or a precise evidence gap, with resolved scope and omissions. If the user later requests capture or correction, route that separate work to the corresponding contribution skill.
