What this skill does
Knowledge Synthesis The last mile of enterprise search. Takes raw results from multiple sources and produces a coherent, trustworthy answer. The Goal Transform this: Into this: Deduplication Cross-Source Deduplication The same information often appears in multiple places. Identify and merge duplicates: Signals that results are about the same thing: Same or very similar text content Same author/sender Timestamps within a short window (same day or adjacent days) References to the same entity (project name, document, decision) One source references another ("as discussed in ~~chat", "per the email", "see the doc") How to merge: Combine into a single narrative item Cite all sources where it appeared Use the most complete version as the primary text Add unique details from each source Deduplication Priority When the same information exists in multiple sources, prefer: What NOT to Deduplicate Keep as separate items when: The same topic is discussed but with different conclusions Different people express different viewpoints The information evolved meaningfully between sources (v1 vs v2 of a decision) Different time periods are represented Citation and Source Attribution Every claim in the synthesized answer must be attributable to a source. Attribution Format Inline for direct references: Source list at the end for completeness: Attribution Rules Always name the source type (~~chat, ~~email, ~~cloud storage, etc.) Include the specific location (channel, folder, thread) Include the date or relative time Include the author when relevant Include document/thread titles when available For ~~chat, note the channel name For ~~email, note the subject line and sender For ~~cloud storage, note the document title Confidence Levels Not all results are equally trustworthy. …
