+description: Audit a scoped GEWU collection for stale claims, duplicate candidates, contradictions and missing relationships, and propose authorized corrections with preserved history.

+# Curate scoped knowledge
+
+Read the pack's [evidence](../../protocols/EVIDENCE.md), [scope](../../protocols/SCOPE.md) and [contribution](../../protocols/CONTRIBUTIONS.md) protocols, then use the [curation pipeline](../../pipelines/curate.md).
+
+Identify the requested audit and bound its collection/budget. For a report-only request, do not submit proposals. Inspect candidate nodes, source revisions, dates and relationships before recommending a change. Similarity nominates candidates; it does not prove duplicates. Preserve incompatible claims and explain the conditions under which they differ.
+
+For requested corrections, submit typed stale flags, supersession or relationship proposals supported by inspected records. Merges, promotion and protected changes follow their separate policy/owner gates. Never silently delete a node, rewrite canonical files or treat read scope as change authority.
+
+Report examined coverage, findings, proposed/accepted changes and unresolved exceptions. Unsupported curation tools remain unavailable; do not substitute raw SQL or filesystem edits.

+description: Process explicitly selected sources for a GEWU project into evidence-bound MCP proposals, with support assessments, coverage and resumable receipts.
+---
+# Ingest selected sources
+
+Read the pack's [evidence](../../protocols/EVIDENCE.md), [scope](../../protocols/SCOPE.md) and [contribution](../../protocols/CONTRIBUTIONS.md) protocols, then use the [ingestion pipeline](../../pipelines/ingest.md).
+
+Inputs are the selected source(s), explicit project and the user's research objective. Inspect existing source identity/revisions before creating duplicates. Retrieve the project lens and supported tool/schema contract; use the connector for local byte transfer. If the service is unavailable, report the blocked stage and only prepare an unaccepted local draft when that work was requested.
+
+Extract useful atomic assertions, problems, techniques or cases with their conditions. Preserve the service's exact source/extraction/location bindings. Map each factual field to evidence; assess semantic support separately. Record triage exclusions and skipped/deferred sections. Optimize for useful coverage rather than maximum note count.
+
+Submit bounded bundles under the affected project/shared policies. Repair actionable findings without weakening evidence, changing scope to evade policy or assuming owner authority. Resume uncertain calls through status lookup. Report accepted node IDs and receipts, pending/rejected work, archive/extraction limits and actual coverage. A successful upload or schema check is not a completed ingestion.

+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.

+description: Create a GEWU comparison, brief or synthesis from accepted revision-bound inputs, preserving conditions, disagreement and dependencies before any requested MCP submission.
+---
+# Synthesize evidence
+
+Read the pack's [evidence](../../protocols/EVIDENCE.md), [scope](../../protocols/SCOPE.md) and [contribution](../../protocols/CONTRIBUTIONS.md) protocols, then use the [synthesis pipeline](../../pipelines/synthesize.md).
+
+Identify audience, purpose, scope and requested output. Retrieve accepted input revisions and build a dependency inventory. Compare conditions, methods, observations and limitations before composing. Label new interpretation and cite the accepted records it depends on. Preserve contradictory evidence and unknown values.
+
+Audit factual statements and dates against the input inventory. Changing an input revision requires rechecking affected statements. A draft may be written locally when requested; do not report it as saved GEWU knowledge. Submit a synthesis proposal only when the user requested a knowledge contribution and the service exposes a compatible synthesis contract.
+
+Return the artifact, dependency inventory, limitations and receipt if accepted. If synthesis submission is unavailable, keep the draft and identify that exact missing capability. The skill does not add a server-side reasoning agent or website authoring path.
