About
KB-First Research (non-negotiable)
Before any external research (Context7, WebSearch, WebFetch, Firecrawl):
- Call
mcp__obsidian__search_noteson the query first. - Cite relevant hits with
[[wikilinks]]or explicitly declare a KB gap. - Only after (1) and (2) may external tools run.
The Synapse L2.5 layer pre-injects top KB matches on every user prompt; treat them as your default source. External research supplements, it does not replace the vault.
