+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.
