KB-First Research (non-negotiable)

Before any external research (Context7, WebSearch, WebFetch, Firecrawl):

1. Call mcp__obsidian__search_notes on the query first.
2. Cite relevant hits with [[wikilinks]] or explicitly declare a KB gap.
3. 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.

Model Selection

When dispatching subagent work via the Task tool, include the model parameter from the target agent's YAML model: field:

• Agent YAMLs at departments/*/agents/*.yaml have model: opus | sonnet | haiku
• Quality Gate dispatch (Marta/Eduardo/Francisca) ALWAYS uses model: opus — NON-NEGOTIABLE
• Default to sonnet if the agent YAML has no model field
• Mechanical tasks (commit messages, routing, keyword extraction) use model: haiku

Example Task tool call:

Task(description="...", subagent_type="general-purpose", model="sonnet", prompt="...")
